我不是很理解“rational”一词， 整个题目考什么点呢？谁能告诉我思路啊！谢谢！！！
In class we discussed a strange auction whereby a former Harvard professor auctioned off a $100 dollar bill. Whoever was willing to pay the highest for it would be the winner and would simply settle up with the professor by paying his bid. However, there was a strange twist to the game. Whoever had the second highest bid still had to pay the professor but did not get anything in return. I shared with you the results of the experiment and it turned out the winning bid was over $400. Explain how and why this was a rational outcome even though to a casual observer this seems quite absurd. Cite an example from life that seems remarkably similar to this situation? Make sure to explain how it is similar.
