Concept:The word "review" means to look at or examine something again, especially with the purpose of checking or improving it.
Explanation:In the sentence, the students were told to "review" their assignments.
This means they should go through the work they have already done once more, carefully, to find mistakes or make corrections.
Now, consider the options:
Option A: re-examine — to look over or inspect again carefully. This matches the meaning of review.
Option B: recount — to count again or narrate; not suitable for assignments.
Option C: inspect — to look at closely, but without the sense of "again". Review implies a second look.
Option D: return — to give back; clearly wrong.
Thus, the nearest meaning is "re-examine".
Answer:A. re-examine
