Answer 1

You can get a part-time job when you are 16 years old. [It depends on the individual state law.]

You can ride a moped when you are 16 years old. [This, too, is state-by-state, but for the most part, from what I've read, there aren't separate laws for mopeds and cars and motorcycles.]

You can't leave school until you are 18 years old. [This, too, is state-by-state.]

You must be 17 (with parental consent) and 18 (without parental consent) to join the army.
