(单选题)

What did the writer’s thought experiment prove?

A.Good teachers represent higher test scores.

B.Excellence is regarded as a rare thing.

C.American tests are usually too easy.

D.Students don’t meet the test standards.

参考答案：B

参考解析：

推理判断题。由第三段第四句“My little thought experiment uncovers a truth that we have been taught to respond with doubt whenever all members of any group are successful.”（我这个小的思维实验揭示了一个真理：即每当任何群体的所有成员都成功时，每次无论是哪个组内成员全部成功的时候，我们总是被教导持怀疑的态度来回应）可知，我们总是认为优秀是一件很稀有的事情，所以我们不相信一群人都同时很优秀。故选B。
