Hmmm...I keep trying these answers, but it says it's wrong. I'm not sure why...

Oh I see, the answer to "compounds are molecules" was in fact "Sometimes." Not exactly sure why, though...

The difference may be semantic. Compounds ALWAYS CONSIST of molecules but you may only SOMETIMES have a single molecule of a compound.
That may be the problem.
