Select the most appropriate option to fill inblank No. 2.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. after.
Context: The blank refers to the time following the lecture, so the word to be filled must indicate something happening once the lecture is finished.
Meaning of the options:
Until: means up to the time of, not suitable here as the event happens after the lecture.
After: means following in time, fits perfectly in this context.
While: means during the time something else happens, not suitable here.
As long as: means provided that or during the entire time, not appropriate here.
Correct word: After
Reason: The students gathered to ask questions once the lecture was over, so “after” is the correct choice. Other options do not correctly express the sequence of events.
Final sentence: After it was over, the students gathered to ask questions.
Hence, the chosen option will be correct.
