Here's a question: John couldn't smile. He wasn't sad,  he didn't have the muscles for it anymore.   But he made the kids happy by standing on his head when he did what?

Here are possible answers to this question:
- make jokes
- frown
- make others happy too
- cry
- rainbow

I believe the correct choice is "frown", here's why:
