was asleep/was sleeping/were sleeping

Everyone was asleep/was sleeping/were sleeping when I came home.

  1. Which one is correct?
  2. Is “Everyone” singular?

The entrepreneur has collected many informations/a lot of information about the investment opportunity.

Which one is correct at the bold part?

“was asleep” and “was sleeping” are both correct. “were sleeping” is incorrect because “everyone” is grammatically singular.

“information” is an uncountable noun, so “informations” is always wrong. “a lot of information” is correct.

Thanks! I understand now. But I would ask you, between was asleep and was sleeping which one would be better in this sentence.

Both are fine.

They are equally good and mean the same.
