LMAO ... I would have struggled the same way with that 'overthinking' the answer cause it cannot be that obvious ... but sadly many curricula are not designed to get you to 'think for yourself' but rather just regurgitate the thoughts of someone else on the matter about what is 'right' .... this is why I have a hard time in some classroom settings because educators do not like when I 'debate' an answer with them on a test cause IMO there are LOTS of ways to approach things and therefore no 'right or wrong' answer to much of life
