The title of moral education short story

In May p>21, Madison Middle School in Nevada, USA, gave such a question in the entrance examination: Bill? There are five locked drawers on Gates' desk, which are labeled with wealth, interest, happiness, honor and success. Gates always takes only one key and locks the other four in the drawer. Which key does Gates take? In which drawer or drawers are the other four locks?

A mainland student who just immigrated to the United States happened to catch up with this exam. After seeing this topic, he panicked because he didn't know whether it was a Chinese problem or a math problem. After the exam, he went to ask his guarantor, a director of the school. The director told him that it was an intelligent test, the content was not in the book, and there was no standard answer. Everyone could answer it freely according to his own understanding, but the teacher had the right to give a score according to his point of view.

Mainland students got 5 points on this 9-point question. The teacher thinks that he didn't answer a word, which at least shows that he is honest, so he should be given more than half the score. What he can't understand is that his deskmate answered this question, but only got 1 point. The deskmate's answer is that Gates is carrying the key on the wealth drawer, and all the other keys are locked in this drawer.

Later, this question was sent back to China by e-mail. The student said to his classmates in the email, now I know which key Gates brought. Anyone who answers this key has been affirmed and appreciated by the richest man. Are you willing to test it? Maybe you will get some inspiration from it.

We don't know exactly how many answers the students gave. However, it is said that a clever classmate boarded the website of Madison Middle School in the United States, where he posted Bill? Gates' reply to the school. There is a sentence written on the letter: the secret of your life is hidden in what you are most interested in.
