Three 4th year chemical pathology students were so confident that the weekend before their final exams, they decided to go up to Kitwe 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 Ridgeway campus until early Monday morning.
Rather than taking the exam then, they decided to find their lecturer, Dr Kaile, after the exam and explain to him why they missed it.
They explained that they had gone to Kitwe for the weekend with the plan to come back and study 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 lecturer thought it over and then agreed they could take the final exam the following day. The guys were elated and relieved.
They studied that night and went in the next day, at the time the lecturer 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 10 points. It was something simple about describing the basic effect of insulin on carbohydrate metabolism in skeletal muscle.”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 90 points): Which tire?
