Question

Quizplus · Accepted Answer

The original sentence is trying to communicate that guests must stay in their rooms between 11 p.m. and 6 a.m., but it is not grammatically correct. The verb "to stay" does not agree with the subject and is unclear. We need to find which of the answer choices is both grammatically correct and communicates the same idea as the original sentence.
The correct answer communicates the same thing as the original sentence (that guests need to stay in their rooms between 11 p.m. and 6 a.m.) and is grammatically correct since the verb phrase "must stay" agrees with the subject.
Their rooms must have guests in them at all times.
This sentence is grammatically correct, but does not communicate the same idea as the original sentence. The original sentence is trying to communicate that guests must stay in their rooms between 11 p.m. and 6 a.m., not that they should be in their rooms at all times.
Guests to stay in their rooms while sleeping.
This sentence does not communicate the same idea as the original sentence. The original sentence is trying to communicate that guests must stay in their rooms between 11 p.m. and 6 a.m., not that they should be in their rooms when in their rooms. This answer is also grammatically incorrect because it uses the verbs "to stay" and "sleeping", which don't agree with the subject.
