Finals
These four 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?
