The professor told them that they could have another day to study. That evening, both of the boys crammed all night until they were sure that they knew just about everything.

Arriving to class the next morning, each boy was told to go to two separate classrooms to take the exam. Each boy just shrugged and went to the two different parts of the building.

As each sat down, they read the first question.

"For 5 points, explain the contents of an atom."

At this point, they both thought that this was going to be a piece of cake, and answered the question with ease. Then, the test continued.

"For 95 points, tell me which tire it was."
