Final Exam
Four college friends were so confident that the
weekend before finals, they decided to go up to Dallas
and party with some friends up there. They had a
great time. However, after all the partying, they slept
all day Sunday and didn't make it back to Austin until
early Monday morning.
Rather than taking the final then, they decided to find
their professor after the final and explain to him why
they missed it.
They explained that they had gone to Dallas for the
weekend with the plan to come back and study but,
unfortunately, they had a flat tire on the way back,
didn't have a spare, and couldn't get help for a long
time. As a result, they missed the final.
The Professor thought it over and then agreed they could
make up the final the following day. The guys were
elated and relieved.
They studied that night and went in the next day at the
time the professor had told them. He placed them in
separate rooms and handed each of them a test booklet,
and told them to begin.
They looked at the first problem, worth 5 points. It was
something simple about free radical formation. "Cool,"
they thought at the same time, each one in his
separate room. "This is going to be easy."
Each finished the problem and then turned the page. On
the second page was written:
(For 95 points): Which tire?
