I think () of us could study last night because of the loud noise.

I think () of us could study last night because of the loud noise.

• A. None
• B. Some
• C. Most
• D. All

Answer: (A)

The main idea is choosing how many people in a group could do something given a disruptive condition. “None of us could study last night because of the loud noise” says that zero people in the group were able to study. “None” clearly communicates that no one was able to do it, which fits the idea that the loud noise affected everyone. If you used “some,” “most,” or “all,” you’d be implying that at least one, or most, or every person could still study despite the noise, which doesn’t align with the cause given. So the sentence makes the most sense with none of us.
