This document presents a 4 question quiz that tests logical thinking and memory. The questions involve putting animals like giraffes and elephants in a refrigerator, which animal does not attend an animal conference, and how to cross a river with crocodiles. Getting questions correct requires thinking through the consequences of actions and remembering details. Most professionals miss all the questions, while preschoolers often get some right, suggesting professionals do not have as much brainpower as 4 year olds.
