From the words lettered A to D, choose the word or group of words that best completes the sentence.
Everyone must be ...bed by 9.00p.m
Answer Details
The correct answer is "in".
The sentence means that everyone must be in bed by 9.00p.m., which means they should already be lying down and sleeping by that time.
Option A "over" is incorrect because it does not make sense in the context of the sentence. Option B "inside" is also incorrect because it does not convey the meaning of the sentence correctly. Option C "on" is incorrect because it does not make sense in the context of the sentence. Therefore, the correct option is D "in".
