Impossibly Possible?

All these riddles have been cleverly compiled to stimulate that human power house you hide under your skull. This is what makes us different from animals (that and the fact we have opposable thumbs, obviously).

The fact that we have the ability to analyse and problem solve is why we are at the top of the food chain.
All these riddles have relatively simple answers but naturally the human nature will trigger a flare in your brain and make you over think a situation and convince you that the answer is more complicated than it seems.

Are you able to prove you can simplify problems and find the correct yet less obvious answer?
