Four students walked in halfway through the final. “Sorry,” they said, “we had a flat tire.” As understanding, I said that if they could all answer just one question correctly, I would give them each an A for the exam. The students agreed. So I placed them in four separate corners and handed each one a piece of paper, said, “Write down which tire was flat.”
期末考試進(jìn)行到一半,四個學(xué)生才進(jìn)來。他們說:“對不起,我們的一個車胎爆了?!睂λ麄儽硎纠斫?,我說如果他們都能夠正確地回答一道題,我就給他們每人一個A。他們同意了。我讓他們四個人分開坐在四個角落里,然后給他們每人一張紙,上面寫著:“寫出哪一個車胎爆了。”
