Rewrite half of questions to be true

[lemonadee71]

Atm, a LOT of questions have their answer as false. I think we should rewrite at least half of them to true. It'd be a simple rewrite like Dogs can only see in black and white to Dogs can see colors other than black and white. This is to mitigate predictability. If you just choose myth every time without even reading the question, you'll still get a decent score. @bappyasif
