20 questions every adult should answer. If you know who Albert Einstein’s first wife was, then you won’t be fooled.

The second ones, on the other hand, are those who remember that they once stumbled upon the answer to that question and even though they like to read and learn new things they tend to forget some of the facts. In their attempt to remember, they ask for a hint or hesitate a bit until they are sure of their answer.
