marco_v on How to answer summary completion questions properly?

That fits a two-word limit, but the limit alone doesn't decide whether it's correct. 'Came from' allows 'the students'; the passage and full task instructions determine whether the article belongs here.

If the summary says 'came from', using 'the students' implies a specific group already mentioned. In the example, the passage only gives 'students', so the article changes the meaning slightly. For a gap fill, it is safer to copy the exact phrase from the passage when possible.
