Can you solve these physics riddles? ft Simone Giertz - Part 1/3

I think the one about the screw it because, let's say you have a piece of wood. And you need your left hand to screw it in and tighten it. Since it's awkward to turn it any other way, you turn it like you're turning a motorcycle handle. So clockwise when you're looking from the right. It's also the same way the left pedal goes so you're basically screwing the screw in all the time?
