B: From the suction from the piston moving down, or C: From atmospheric pressure pushing it in. I chose B, because if the piston wasn't moving no air would move, but I bet they wanted to hear C

Don't peek at the spoiler until after you've taken the test.!

You know what? I did the exact same thing.

Anyhow, the test seemed to rely a lot on common sense and (especially in the mechanical portion) stepping back and double-checking your answer. It's a cute little quiz, but not exactly something I'd call the defining measure of how good someone is mechanically.
