Okay so if we the 2nd method, Let's say you get the 1st answer correctly. Add 1 to correct and show seed. If it's the wrong the same thing but don't do anything and add 1 to wrong.
But what about the 2nd question. There are 3 possibilities. If you get the 1st question wrong, and 2nd question correct it'll show seed. If you get both questions wrong. It'll show 'X'. If you get both questions right it'll show sapling. There are too many possibilities as you increase the question no.
