Input: Consider Input: I don't feel like The Hunger Games: Catching Fire fully explained this. It seems awfully convenient to have a tree where lightning strikes 12 times every hour. What would possibly be the point of this in the "game"? It would only kill someone if they were on it.

Output: What was the purpose of the lightning tree?

Input: Consider Input: In Terminator: Genisys, Kyle Reese was sent back in time but didn't have a child with Sarah Connor within that timeline. How is John Connor alive if Kyle and Sarah didn't get together in 1984?

Output: How is John Connor alive if Kyle and Sarah didn't get together in 1984?

Output: Why was Sam "Ace" Rothstein spared by the bosses?
