For example, doctors think that pre-school children need between 10 and 12 hours a night; school children between 9 and 11 hours; and adults between 7 and 9 hours. There are exceptional【C2】______ of old people who only sleep between 2 and 3 hours a day and continue to be active and healthy.

There are also【C6】______ about mathematicians who solve difficult problems during sleep, because their【C7】______ minds continue working on the problem.

选项
A、causes
B、cases
C、factors
D、proofs

B
解析
A项causes意为:"原因",B项cases意为:"情况",C项factors意为:"因素,要素",D项proofs意为:"证据,证明"。从句意看,空格中应填入B项。本句的意思是:"有一天只睡2至3小时,却依然非常活跃、健康的老人的例外情况"。其他三个选项均与句意不符。
