really hard to have to think about stuff :D
but to figure out which is a subset, pick one, and see if it's possible to be in that set but not in set A.
like the first one, it's children over 7, well, a child of 8 years old <not that age really matters ;) > is in that set but could never be in set A since if you're 8, then you're not between 3 and 7

haha
