    1) Correct.

    2) This is a bit tricky. Note that the students enrolled in your college, can only be either full time or part time. If we consider part-time and full-time students enrolled in your college, we are actually taking all the students in your college. So yes, this is a defined set.

    3) Correct. Who is to judge who are the worst?

    4) Correct. How old is elderly?
