题目解析:
利用题干关键短语 European intellecutals 定位到原文最后一句的 best brains:Science, mathematics, poetry, law, historical writing, religious speculation, translation, and classical studies all began to flourish; throughout most of the twelfth century, most of the continent's best brains flocked to southern Europe.这里可以读到,南方普遍识字能力高,科学,数学,诗歌,法律等等 all began to flourish。最后提到这就是为什么欧洲最出色的大脑 flocked to southern Europe,flock to 意为成群结队涌入到,等于题目中的 move。因此答案为 C。A 选项的 commerce 商业没有提到;B 选项虽然提到了 educated people,但是其意为付给有教育的人更多的钱,这在文中没有提到,属于偷换概念;D 选项的 needed teachers 也没有提到,因此答案为 C 选项。
