 If one got all 4 questions wrong it said they have the brain of a four-year old, I got 1 question ok, does that mean I have the brain of a five-year old?

I´ve already known the first two ones. Got the other ones wrong though That´s so true, we´re taught to think in patterns and lose the creative thinking ability. School kills it I remember there was once a question: A dog has a few cans attached to his tail. Taken that the dog weighs 30kg and the speed of sound is 340m/s, what speed would the dog have to have in order not to be heard? The simpliest answer was suggested by a pre-schooler who said that the dog would have to stand still. Easy, huh?
