How DET Interactive Writing works
Interactive Writing has two connected responses. The initial directions and prompt appear for 30 seconds before a five-minute response period. You then receive a follow-up question and have three minutes to answer it. The second timer starts with the follow-up directions. You can see your first response during the second step. These details come from the official DET task guidance, checked November 11, 2026.
The second question asks you to take the topic further. It may invite another perspective, a consequence, a solution, or a broader application. Read it carefully before continuing: an excellent answer to Part 1 does not answer Part 2 automatically. Duolingo's guidance does not publish a task-specific minimum word count. Write relevant, developed English within the available time rather than chase a memorized total.
How to use these paired examples
- Choose a topic and read only the first prompt. Plan mentally during a 30-second preview, then write for five minutes.
- Open the follow-up and write for three minutes. Keep your initial answer visible but do not revise it during this step.
- Open the models and compare prompt coverage, development, organization, and language. Find one change you could apply to a different topic.
These are original PrepEx teaching examples, not official DET questions or responses with official scores. Each follow-up below is a fixed example paired with the displayed model. On the real test, the follow-up is based on your own first response; this static collection does not analyze your writing or reproduce that selection process. A follow-up can still be useful practice if your answer takes a different position, but do not force your ideas to match the model.
Some examples include a limited draft and a revised excerpt. Those excerpts show one improvement; they are not complete timed responses. The full Part 1 and Part 2 models demonstrate possible answers, not required lengths or paragraph plans.
20 Interactive Writing prompts with both model answers
1. Learning a practical skill

How could you help someone who finds this skill difficult to learn?
Read both model answers and the development notes
Part 1 model answer
My uncle taught me to repair a punctured bicycle tire when I started cycling to college. At first, I expected him to do the repair while I watched. Instead, he asked me to remove the wheel and find the hole myself. I could not hear any escaping air, so he showed me how bubbles appeared when we held the tube in water. After that, he demonstrated the patch once and let me finish the job.
The lesson has saved me several long walks home. More importantly, it changed how I react when something breaks. I now look for the cause before assuming that I need a replacement. I still take complicated repairs to a mechanic, but an ordinary puncture no longer ruins my plans.
Part 2 model answer
I would divide the repair into small stages and let the learner complete each one. Removing a wheel and applying a patch at the same time can feel confusing if both actions are unfamiliar. A spare wheel would also help because there would be no pressure to finish before a journey. If the patch failed, we could check whether the surface was clean and dry, then try again. The aim would be to explain the reason for each step so the person could eventually work without me.
How the follow-up develops the answer
- Part 1 follows a real learning sequence: expectation, difficulty, demonstration, independent action.
- Part 2 changes from personal experience to teaching. The spare wheel and diagnosis of a failed patch develop a new angle instead of retelling the lesson.
One revision to study
Limited draft: My uncle taught me to fix bikes. It was useful and I learned a lot. He is a good teacher.
Revised excerpt: When I could not find the puncture by listening, my uncle held the tube in water. The bubbles showed me exactly where the hole was.
Why it helps: The revision replaces a general judgment with an obstacle, an action, and an observable result. It is a revised excerpt, not a complete timed answer.
2. A quieter place to study
Part 1 prompt · five minutes
Some people study best in a quiet room, while others prefer a place with background activity. Which do you prefer, and why?
Reveal the follow-up prompt · three minutes
How might your preferred study environment change when you work with other people?
Read both model answers and the development notes
Part 1 model answer
I prefer a quiet room when I have to understand something unfamiliar. Background conversation pulls my attention away from the page, especially if I can hear individual words. I may read a paragraph several times without noticing that I have missed its main point. In a quiet room, I can pause over a difficult sentence and connect it with what came before.
That does not mean I need complete silence for every task. I sometimes review vocabulary on a bus because the activity is short and familiar. For longer work, however, I choose a library desk away from the entrance. Keeping my phone in my bag matters as much as finding a quiet location. Otherwise, I bring a source of interruption into the room myself.
Part 2 model answer
For group work, I would choose a room where conversation is permitted. Silence would be unhelpful if we needed to compare ideas or explain a calculation. I would still avoid a crowded cafe, since hearing one another should not require speaking loudly. We could begin with a short period of individual reading and then discuss specific questions. This would preserve the concentration I value while giving everyone something useful to contribute.
How the follow-up develops the answer
- The preference is qualified with a different task, not weakened by an unrelated counterargument.
- The follow-up applies the same need for concentration to a changed social setting and proposes a workable routine.
3. A useful mistake
Part 1 prompt · five minutes
Tell the story of a mistake that taught you something useful. What happened, and what did you learn?

What could a school or workplace do to make it easier for people to learn from mistakes?
Read both model answers and the development notes
Part 1 model answer
I once sent a club newsletter with the wrong date for a meeting. I had copied the previous issue and changed the main article, but I forgot the small calendar box at the bottom. Several members arrived a day early. When the organizer called me, my first reaction was to explain how busy I had been. That would not have helped the people who had wasted a trip.
I sent a correction, apologized, and checked that the new date appeared consistently in every announcement. I also made a short checklist for later newsletters. The mistake taught me that familiar documents can be risky because they look finished before they have been checked. Now I review practical details separately from the wording, even when I have only made small edits.
Part 2 model answer
A school or workplace could ask people to explain what went wrong and what will change, rather than simply naming who was responsible. For example, a newsletter team could keep a shared checklist and ask a second person to verify dates. People still need to correct the harm they cause. However, if every admitted error leads to public embarrassment, they may hide small problems until those problems become harder to fix. A brief review focused on prevention would be more useful.
How the follow-up develops the answer
- The narrative includes a consequence and a changed habit, so the lesson grows out of the event.
- The second response moves to organizational practice and distinguishes accountability from humiliation.
4. Borrowing everyday tools
Part 1 prompt · five minutes
Would you prefer to borrow an item you rarely use or buy your own? Explain your choice with an example.
Reveal the follow-up prompt · three minutes
What difficulties might arise when people share items, and how could they handle them?
Read both model answers and the development notes
Part 1 model answer
I would usually borrow something that I need only once or twice a year. A large cooking pot is a good example. I might use one for a club dinner, but it would occupy a cupboard for the rest of the year. Borrowing it from a neighbor would save both money and space.
I would buy my own equipment if reliability were especially important. If I used a camera for paid work, depending on someone else's availability would be risky. The decision therefore depends on the cost of being unable to use the item when I need it. For an occasional social event, arranging a loan in advance seems reasonable. I would return the pot clean and promptly, since a convenient arrangement should work for its owner too.
Part 2 model answer
The main difficulty is uncertainty about responsibility. A small scratch may already be present, or an item may stop working during normal use. Before borrowing something expensive, both people could check its condition and agree on a return date. They should also discuss what would happen if it were damaged. This may feel unnecessarily formal between friends, but a short conversation is easier than an argument later. For inexpensive items, a simple message recording the arrangement may be enough.
How the follow-up develops the answer
- The answer uses one concrete item and a contrasting condition; it does not claim borrowing is always best.
- The follow-up adds the missing issue of responsibility and offers proportionate precautions.
5. An ordinary place worth visiting
Part 1 prompt · five minutes
Describe an everyday place in your area that you would recommend to a visitor. Why is it worth visiting?
Reveal the follow-up prompt · three minutes
How could visitors enjoy this place while respecting the people who use it regularly?
Read both model answers and the development notes
Part 1 model answer
I would recommend the covered market near our bus station. It is not a famous attraction, but it shows how the neighborhood works. Early in the morning, sellers arrange vegetables while nearby office workers stop for breakfast. By lunchtime, the small food stalls are busy, and customers often share tables.
A visitor could try a simple meal and see products that are less common in a supermarket. I particularly like the stall that sells different kinds of beans because the owner explains how to cook them. The market is also easy to reach without a car. I would suggest going outside the busiest lunch period, when there is more room to look around and the sellers have time to talk.
Part 2 model answer
Visitors should remember that the market is a workplace and a place where residents buy necessities. They could stand to one side while deciding what to order and ask permission before photographing a stallholder. Buying a small meal would support a business, but there should be no pressure to purchase something from every stall. Learning a few polite expressions would also help. Respectful curiosity would make the visit more pleasant for customers and sellers alike.
How the follow-up develops the answer
- The description explains what a visitor can actually do, rather than relying on adjectives such as amazing.
- Part 2 introduces behavior and relationships; the place stays the same while the purpose of the answer changes.
One revision to study
Limited draft: The market is very interesting and beautiful. Everybody should go there because it is amazing.
Revised excerpt: At lunchtime, customers share tables beside the food stalls. A visitor can try a simple meal while seeing how people use the market during an ordinary workday.
Why it helps: Concrete activity explains the recommendation. The claim about everybody is replaced by a specific reason a visitor might enjoy the place.
6. Planning a free afternoon
Part 1 prompt · five minutes
Do you prefer to plan your free time carefully or decide what to do at the last minute? Explain your preference.
Reveal the follow-up prompt · three minutes
How would you organize free time with someone whose preference is different from yours?
Read both model answers and the development notes
Part 1 model answer
I like to leave some free time unplanned. My classes and work shifts already follow a timetable, so I enjoy an afternoon when I can choose an activity according to my energy. If the weather is pleasant, I might walk along the river. If I feel tired, I can stay home and read without feeling that I have failed to complete a plan.
There are limits to this approach. I book tickets in advance when an event is likely to sell out, and I never assume that friends will be available at short notice. What I dislike is filling every free hour before the weekend begins. A little empty space lets me notice what I actually want to do instead of treating leisure as another list of obligations.
Part 2 model answer
I would agree on one fixed activity and leave the rest flexible. For instance, we could book lunch at noon and decide afterward whether to visit a gallery or take a walk. My friend would know when we were meeting and would not have to wait for a last-minute message. I would still have some choice during the afternoon. Explaining our preferences beforehand would prevent either of us from interpreting a different planning style as a lack of interest.
How the follow-up develops the answer
- The response gives a clear preference with reasonable boundaries.
- The follow-up introduces a compromise and explains the interpersonal problem that the arrangement prevents.
7. Learning through a project
Part 1 prompt · five minutes
Should students learn a new subject mainly through explanations or through practical projects? Give your opinion and reasons.
Reveal the follow-up prompt · three minutes
What could a teacher do if a project becomes enjoyable but students stop learning from it?
Read both model answers and the development notes
Part 1 model answer
I would begin with a short explanation and then give students a project. An explanation provides a useful starting point, but students may not realize what they misunderstand until they have to make a decision themselves. In a basic design class, for example, hearing about balance is different from building a model that keeps falling over.
The project should be small enough for beginners to finish and revise. Otherwise, they may spend all their time dealing with materials or software instead of learning the subject. I do not think teachers need to choose one method permanently. A brief explanation can introduce an idea, a project can expose difficulties, and a later discussion can help students connect their experience with the original concept.
Part 2 model answer
The teacher could pause the activity and ask students to explain a choice they have made. If they are building a model, they might compare two designs and predict which will hold more weight. This would make the learning goal visible again. The teacher could then ask them to test the prediction and record what changed. Enjoyment would remain useful, but it would support observation and reasoning instead of becoming the only purpose of the lesson.
How the follow-up develops the answer
- The argument is organized around a learning sequence, not a list of unrelated advantages.
- The second answer supplies a concrete intervention for the specific problem in the question.
8. Keeping an object
Part 1 prompt · five minutes
Describe an inexpensive object that you have kept for a long time. Why have you kept it?
Reveal the follow-up prompt · three minutes
How might the meaning of an object change as a person gets older?
Read both model answers and the development notes
Part 1 model answer
I have kept a small notebook from my first summer job. It contains shopping lists, bus times, and instructions for tasks that now seem simple. The cover is bent, and several pages have come loose. I could replace it easily, but a new notebook would not contain those records.
At the time, I wrote everything down because I was nervous about forgetting instructions. Looking at the pages now reminds me how much I learned in a few weeks. I can see the point where detailed reminders became shorter because I no longer needed every step explained. I rarely read the notebook from beginning to end. Keeping it in a drawer is enough to remind me that becoming comfortable with a new responsibility takes practice.
Part 2 model answer
An object can shift from being a useful tool to being evidence of an earlier life. My notebook originally helped me complete daily tasks; now it helps me remember what being a beginner felt like. Later, I may notice different details, such as the names of coworkers I have lost contact with. This does not mean every old possession needs to be kept. Its value depends on whether it still connects the owner with an experience that matters.
How the follow-up develops the answer
- Physical details are tied to the reason for keeping the object.
- The extension adds time and changing interpretation, rather than simply repeating that the notebook has memories.
9. Changing a daily routine
Part 1 prompt · five minutes
Describe a change you made to a daily routine. What led to the change, and what effect did it have?
Reveal the follow-up prompt · three minutes
Why can a useful change still be difficult to maintain?
Read both model answers and the development notes
Part 1 model answer
Last term, I began preparing my bag before going to bed. I used to leave everything until the morning, when I was often looking for a charger while trying to eat breakfast. After arriving at class without an assignment I had already finished, I decided the routine needed to change.
The new habit takes only a few minutes. I check the next day's timetable and put the necessary books and equipment by the door. Mornings have become less hurried, and I am less likely to forget something. The habit has not solved every problem with my schedule, but it has removed one predictable source of stress. It also makes me notice unfinished work early enough to deal with it before I am about to leave.
Part 2 model answer
A change may be useful without producing an immediate reward. Packing a bag at night feels unnecessary when someone is tired and tomorrow still seems far away. The benefit appears only the next morning, so it is easy to postpone the action. I maintain the habit by doing it just after washing my dinner dishes, an activity I already complete. Linking the two actions makes remembering easier than depending on a fresh decision every evening.
How the follow-up develops the answer
- Cause, action, and effect are all explicit, with a realistic limit on the benefit.
- Part 2 explains the obstacle through delayed reward and adds a new maintenance strategy.
10. A neighborhood event
Part 1 prompt · five minutes
Would you enjoy helping organize a small event in your neighborhood? Explain what kind of role would suit you and why.
Reveal the follow-up prompt · three minutes
How could organizers encourage people who do not usually attend neighborhood events to participate?
Read both model answers and the development notes
Part 1 model answer
I would enjoy helping organize a neighborhood book exchange, especially by arranging the books and welcoming people. I like practical tasks with a visible result, and this role would give me a reason to speak to neighbors I do not know well. I would be less comfortable making announcements to a large crowd.
A book exchange could be simple enough for volunteers to manage. People could bring books they no longer need and choose others to take home. I would group them loosely by subject and make sure the children's books were easy to reach. We would also need a plan for books left at the end. Agreeing with a local charity beforehand would prevent the event from leaving one volunteer with boxes they could not store.
Part 2 model answer
Organizers could make it clear that bringing a book is optional. Someone who has recently moved to the area may have nothing to contribute but still want to meet people. Notices in several languages and an accessible location would also reduce practical barriers. I would avoid describing the event as only for enthusiastic readers, since that could discourage casual visitors. A small seating area would let people stop briefly without committing to a long activity.
How the follow-up develops the answer
- A specific role supports the personal answer; the leftover-books problem makes the plan credible.
- The follow-up considers excluded participants and concrete barriers rather than merely recommending more advertising.
11. Choosing news carefully
Part 1 prompt · five minutes
When you hear surprising news, do you usually share it immediately or check it first? Explain your approach.
Reveal the follow-up prompt · three minutes
How could you respond if a friend shared information that appeared to be incorrect?
Read both model answers and the development notes
Part 1 model answer
I usually check surprising news before passing it on. A dramatic headline may leave out an important condition, and a photograph can be genuine while its caption is wrong. Sharing a story takes only a moment, but correcting it later does not guarantee that everyone who saw the original will see the correction.
My first step is to find where the information came from. If a message says a local service is closing, I look for an announcement from that service rather than another copy of the message. I also check the date, since old information can become misleading when it reappears. If I cannot verify the claim, I would rather wait. I can still discuss it with someone while clearly saying that I am unsure.
Part 2 model answer
I would contact the friend privately and ask where the information came from. They may have a source I have not seen. If I found a clear correction, I would send the link and explain the specific difference, such as an outdated date. Calling the person careless would probably make the conversation defensive. The useful goal would be to correct the information and, if necessary, encourage them to update the people who received it.
How the follow-up develops the answer
- The response explains a verification process without inventing research or statistics.
- The follow-up shifts from evaluating information to handling a relationship respectfully.
One revision to study
Limited draft: In the follow-up, I would check news because checking news is important. As I said, we must check it.
Revised excerpt: I would send my friend the original announcement privately and point out that the message used last year's date. This would correct the claim without embarrassing them in the group.
Why it helps: The revised follow-up answers the new interpersonal question. It adds an action and its purpose instead of repeating Part 1.
12. Working with a new teammate
Part 1 prompt · five minutes
Tell the story of a time you worked with someone whose approach was different from yours. How did you handle the difference?
Reveal the follow-up prompt · three minutes
What could a team do at the beginning of a project to prevent similar misunderstandings?
Read both model answers and the development notes
Part 1 model answer
During a class presentation, I worked with a student who liked to begin designing slides immediately. I preferred to agree on the argument first. For the first two days, we both worked hard but produced material that did not fit together. I assumed he was ignoring the plan, while he thought I was delaying the work.
We eventually compared what each of us needed. I wanted a clear sequence of ideas; he needed something visible to react to. We made a rough outline and then built three sample slides together. This gave us a structure without requiring every detail to be settled. The final presentation was more coherent, and I learned that a different working method does not necessarily mean someone is unwilling to cooperate.
Part 2 model answer
A team could agree on a small first deliverable and explain what it is supposed to test. For our presentation, that could have been an outline with a few sample slides, rather than a complete design. Members should also say when they need feedback and which decisions remain open. A short early meeting would not eliminate every disagreement, but it would make differences visible before people invest hours in incompatible work.
How the follow-up develops the answer
- Both approaches have understandable motives, so the story avoids making one teammate a villain.
- The follow-up extracts a preventive process from the experience and explains its limits.
13. Repairing or replacing
Part 1 prompt · five minutes
When an everyday item breaks, is it better to repair it or replace it? Explain how you would decide.
Reveal the follow-up prompt · three minutes
How could businesses make it easier for customers to make this decision?
Read both model answers and the development notes
Part 1 model answer
I would compare the likely repair cost with the item's remaining usefulness. If a desk lamp only needed a new switch, repairing it could be sensible. Buying a replacement would create another task because I would have to dispose of the old one. However, I would not keep paying for repairs if the lamp had several electrical problems and could no longer be used safely.
It is also important to find out whether a repair is possible before deciding that it is too expensive. People sometimes replace things because they do not know where to get advice. For an item I use often, I would ask for an estimate and a clear description of the fault. That information would matter more to me than the age of the item alone.
Part 2 model answer
Businesses could publish repair prices for common faults and explain which parts are replaceable. A customer should not have to pay a large inspection fee merely to discover that no spare parts exist. Shops could also distinguish a temporary fix from a repair expected to last. Clear information would help people compare options honestly. It would not make repair the right choice in every case, but it would reduce decisions based only on uncertainty.
How the follow-up develops the answer
- The decision criterion is usefulness and safety, not a blanket moral claim.
- The extension introduces information supplied by businesses and connects it to the uncertainty in Part 1.
14. Trying an unfamiliar activity
Part 1 prompt · five minutes
Describe an activity you were reluctant to try but later enjoyed. What changed your mind?
Reveal the follow-up prompt · three minutes
How could someone encourage a hesitant beginner without putting too much pressure on them?
Read both model answers and the development notes
Part 1 model answer
I was reluctant to join a beginners' drawing class because I thought everyone else would already be good at it. A friend invited me several times, but I kept saying I was busy. Eventually, she showed me some exercises from her first lesson. They were simple studies of cups and shoes, not impressive finished pictures, so the class seemed less intimidating.
At the first session, the teacher asked us to draw an object without looking at the paper. Everyone's result was uneven, which made it easier to stop worrying about mine. I enjoyed paying close attention to shapes I would usually overlook. I still do not draw especially well, but I now attend the class for the concentration and pleasure of the activity rather than to prove that I have talent.
Part 2 model answer
I would give the beginner an accurate idea of what will happen and offer a small first step. Attending one session is less daunting than joining a course for several months. It would also help to say that they could watch part of the activity before participating. Encouragement becomes pressure when refusing starts to feel unacceptable. I would invite the person once, answer their questions, and let them decide whether the timing was right.
How the follow-up develops the answer
- The turning point is specific: seeing beginner exercises changes an inaccurate expectation.
- Part 2 develops the boundary between encouragement and pressure, a new issue connected to the hesitation.
15. A useful public service
Part 1 prompt · five minutes
Which public service has made a noticeable difference to your daily life? Explain its value with an example.
Reveal the follow-up prompt · three minutes
How could the people running this service learn what users need most?
Read both model answers and the development notes
Part 1 model answer
The evening bus service has made the biggest difference to my daily life. My part-time job sometimes finishes after the shops close, and the later buses allow me to travel home without arranging a ride. Before the timetable changed, I had to leave a little early or wait for someone to collect me.
The value is not only the fare I save. A predictable journey lets me accept shifts with more confidence, and my family does not have to change its plans around my work. The service is not perfect: the last bus is often crowded. Even so, extending the operating hours has been more useful to me than adding extra buses during the middle of the day, when I rarely travel.
Part 2 model answer
The operator could ask riders about specific journeys instead of asking only whether they are satisfied. A passenger might rate the service positively while still struggling with the last connection home. Short surveys on buses could be combined with conversations at stops, including with people who cannot use online forms easily. It would also be useful to hear from nonusers, since an unsuitable timetable may be the reason they do not ride.
How the follow-up develops the answer
- The answer shows an effect on work and family arrangements, beyond calling the service convenient.
- The follow-up proposes ways to gather overlooked evidence, including from people absent from current ridership.
16. Learning alone or with others
Part 1 prompt · five minutes
When learning something new outside school, do you prefer to work alone or join a group? Explain your choice.
Reveal the follow-up prompt · three minutes
How could a learner combine the benefits of both approaches?
Read both model answers and the development notes
Part 1 model answer
I prefer to start alone when I am learning something new outside school. I can repeat a basic step as often as I need without worrying that I am slowing anyone down. When I began learning to cook, for example, I made the same simple soup several times. Each attempt taught me something about heat and timing.
A group would have been useful later, once I had questions that I could explain. At the beginning, though, I found it hard to follow advice while also measuring ingredients and watching the pan. Working alone let me give one problem my full attention. I would not choose this method for an activity that required supervision for safety, but it suits ordinary skills that can be practiced in small stages.
Part 2 model answer
A learner could practice a basic task alone and then meet a group to compare results. Someone learning to cook might prepare one dish during the week and bring questions to a weekend class. The group could suggest a technique that the learner had not considered, while individual practice would give them time to test it. Keeping a short record of difficulties would make the group session more focused than simply asking for general advice.
How the follow-up develops the answer
- The preference is explained through attention and pace, with a relevant safety limit.
- The new answer designs a cycle between the two approaches instead of choosing again.

Read both model answers and the development notes
Part 1 model answer
Our class planned to record a short documentary in a public garden, but heavy rain began just as we arrived. We could not protect the camera properly, and the paths were becoming muddy. At first, we considered canceling because the outdoor scenes were central to our idea.
After discussing our options, we moved to a covered community hall nearby, where a gardening club was preparing plants for a sale. With permission, we interviewed two members and filmed their work. The documentary became a story about the people who maintained local green spaces. It was different from our original plan, but it still addressed the topic. I learned that preserving the purpose of a project can be more useful than preserving every detail of the first plan.
Part 2 model answer
People can identify the essential goal and the parts that can change. For our documentary, the goal was to explain a relationship between people and local green spaces; a particular filming location was only one way to do that. Checking access to an indoor location would also have helped. Preparing an alternative does not require predicting every problem. It means having enough information and flexibility to choose another route when the first one becomes impractical.
How the follow-up develops the answer
- The replacement plan still serves the original purpose; the outcome is more than a generic happy ending.
- Part 2 turns the event into a planning principle and adds a practical preparation step.
One revision to study
Limited draft: It rained and we changed the plan. In conclusion, flexibility is very essential in modern society.
Revised excerpt: We kept the documentary's topic but changed its location, interviewing gardeners in a covered hall. This let us continue filming while protecting the equipment.
Why it helps: The revision shows what flexibility meant in this event. The conclusion now follows from the actual decision.
19. Advice that became useful later

When might it be reasonable not to follow another person's advice?
Read both model answers and the development notes
Part 1 model answer
A teacher once advised me to ask a question as soon as I became confused. I thought this would interrupt the lesson and reveal that I was a slow learner. Instead, I tried to understand everything alone after class, which sometimes meant spending an hour on a misunderstanding that a short explanation could have resolved.
My opinion changed during a group assignment. I asked what one instruction meant, and two classmates admitted they had the same question. The teacher clarified it for everyone, and we avoided preparing the wrong material. I now see a precise question as a way of taking responsibility for learning. I still wait for an appropriate moment, but I no longer treat every uncertainty as something I must hide.
Part 2 model answer
It is reasonable to question advice when the advisor does not understand the situation or when circumstances have changed. A method that suits one learner may not suit another. I would ask what problem the advice is intended to solve and compare that with my own needs. In my case, asking questions helped because a specific instruction was unclear. That does not mean interrupting immediately is always appropriate; sometimes writing down the question and asking after class works better.
How the follow-up develops the answer
- The change in opinion follows a particular experience and its outcome.
- Part 2 evaluates the limits of advice while remaining consistent with the lesson in Part 1.

How would you find out whether your proposed improvement had worked?
Read both model answers and the development notes
Part 1 model answer
I would add a few shaded benches beside the path to our local health center. The building is close to the bus stop, but the walk feels long in hot weather, especially for older visitors. At present, the only seats are near the entrance, so people who need to rest halfway have nowhere comfortable to stop.
The benches would not need to be elaborate. They should have backs, be placed on level ground, and leave enough space for wheelchairs and people passing. Shade could come from a simple shelter if existing trees were too far from the path. I would choose this change over a decorative feature because it would help people complete a necessary journey. The seats could also serve residents walking to nearby shops.
Part 2 model answer
I would observe whether people used the benches at different times of day and ask users whether the locations were helpful. Counting users alone would not show everything: a bench might be empty because it becomes too hot in the afternoon. Staff could also check whether it obstructed the path or required frequent repairs. After a trial period, the community could move a seat or improve its shade before installing more.
How the follow-up develops the answer
- The proposed change responds to a clear barrier and includes practical design details.
- The follow-up distinguishes usage from usefulness and explains how evidence could change the proposal.
Review both responses separately
- Task coverage: Underline the sentence or passage that answers each requested point. If the question asks what changed, explain the change rather than only describing the original situation.
- Development: Find a reason, event, example, or consequence that makes your main point understandable. Replace “it was useful” with what it helped you do.
- Follow-up: Identify the new direction in Part 2. Check that you have added relevant content, not paraphrased your first conclusion.
- Coherence: Check what pronouns refer to and whether the sequence of events or ideas is clear. A connector cannot repair an unexplained jump.
- Language: Check complete sentences, tense, agreement, word choice, spelling, and punctuation. Prefer an accurate ordinary expression to an unfamiliar phrase used incorrectly.
The official open-response scoring overview identifies content, coherence, vocabulary, and grammar among the writing considerations. This checklist translates those broad areas into study actions; it is not Duolingo's scoring formula. A better revision on a familiar prompt is useful practice, but a fresh timed answer will show whether you can apply the change independently.

Interactive Writing questions
How many words should I write?
The current official task page gives time limits and encourages relevant, effective English; it does not set a task-specific minimum. These models illustrate development within the task. Their lengths are editorial choices, not official targets.
Should Part 2 repeat my main opinion?
Keep enough connection for the reader to follow, then answer the new question. If Part 2 asks about a difficulty, explain that difficulty and its implications. Repeating the original reasons will not supply the new development.
Can I change my position in the follow-up?
You can qualify or reconsider an idea if the new question leads you there. Explain the relationship clearly. A qualification is more useful than silently contradicting your first answer.
Are these official or scored DET sample answers?
No. They are independent PrepEx examples. Different experiences and opinions can also answer the prompts well. Any numeric score in PrepEx practice is a practice estimate, not an official DET score.
Can I use a memorized template?
A flexible habit, such as answering directly and then explaining a reason, can help. Memorized paragraphs are risky because they may not fit the particular prompt or follow-up. Study the decisions behind these examples and write your own content.
