    They all look to be right except:

    2nd
    F: A∩B⊂B IS true...
    and
    2nd
    G: A∪B⊂A ISN'T necessarily true.

    Let A= {1,2,3}, B= {4,5}.
    A∪B = {1,2,3,4,5}, is not a subset of {1,2,3}.

    Sorry, that's what I meant...

    I accidently put G and F on the same line. I meant to star F and not G...


    But somehow my answers were wrong? o__O

    Nvm! Thanks!

    I realized that C was actually right!
