Hi,

Are the sentences with "could not" correct? I want "could not" to mean impossibility.

Peter could not be in the garden now. I have looked in the garden. There is nobody in the garden.
Peter could not be working in the garden now. I don't see anybody in there.
Peter could not attend the school. The school is closed now.

Thank you very much.

    For the last one, should I say "Peter can't attend the school" or "Peter can't be attending the school"?

    I think "Peter can't attend the school" seems to say Peter lacks the ability to attend the school.
