> A man is running. A dog is behind him barking and growling. What does the man think might happen?

So what's the correct answer here?

* That's a mean dog

* I hope it's on a leash

* I hope it's not going to start running after me

* I hope I don't get bitten

* Where can I hide?

* OMG, I will get rabies!

This was my first thought, there are many different things a human could think of, and we will probably cycle through them all in a few ms. This would have to be multiple choice and then what? The "AI" would have a baseline 25% chance of getting it correct (assuming 4 options).

Multiple choice doesn't work well for captchas. You can just guess and get it 25% of the time correct. Which is fine for spammers.
