Organic Chemistry Test

     This past spring semester, at Yale University, there were two sophomores
who were taking Organic Chemistry and who did pretty well on all of the
quizzes and the midterms and labs, etc., such that going into the  final, they each
had a solid "A."  These two friends were so confident going into the final that
the weekend before finals week (even though the Chem final was on (Monday), they
decided to go up to Harvard and party with some friends up there. So they did
this and had a great time.

     However, with their hangovers and everything, they overslept all
day Sunday and didn't make it back to New Haven until early Monday morning.
Rather than taking the final then, they found the professor after the final
and explain to him why they missed the final.  They told him that they went
up to Cambridge for the weekend, and had planned to come back in time to
study, but that they had a flat tire on the way back and didn't have a spare
and couldn't get help for a long time and so were late getting back to
campus.

    The prof thought this over and then agreed that they could make up the
final on the following day.  The two guys were elated and relieved.
So, they studied that night and went in the next day at the time that the
prof had told them.  He placed them in separate rooms and handed each of them
a test booklet and told them to begin.

     This professor always put each problem on a separate page.  In their
separate rooms, each young man looked at the first problem:

     1.  (5 points)  Explain free radical formation.

This was really simple!  "Cool" they each thought, "this is going to be
easy." They did that problem and then turned the page.

      At the top of the next (and last) page was a very simple question
that looked like this:

     2. (95 Points)     Which tire?
