Build a Sentence: understand the word order
Worked examples by Kate Feng, Language Education Specialist. These separate teaching examples do not reveal the answer to your practice question.
An embedded question
Compare When does the library close? with Do you know when the library closes? The direct question uses does before the subject. Inside the second sentence, the embedded question uses subject–verb order: the library closes. Adding “Do you know” does not leave the rest of the original question unchanged.
A relative clause
In The book that you recommended was already on loan, the words that you recommended describe the book. The main sentence is The book was already on loan. Finding that main structure helps you position the extra clause without losing the subject and verb.
Review the reason, then try another item
After checking an answer, name the structure you missed: question order, a relative clause, agreement or a verb pattern. Use the Build a Sentence strategy guide for a fuller explanation, or the TOEFL grammar course for the underlying pattern. Then return to practice with a new sentence.
