Wait, did they really put 'one two three four five' as an option? That's just the string values, not the actual output. Gotta be more careful with these tricky questions!

Oh man, I remember learning about multimaps in class. This looks like a standard multimap insertion and removal operation. The answer has to be B, right?

Haha, looks like someone's trying to trick us with that 'erase(3)' call. But I bet the answer is still pretty straightforward if you know your multimap stuff.
