问题     Advice to "sleep on it" could be well founded, scientists say. After a good night’s sleep, a problem that seemed insurmountable(不能克服的)the night before can often appear more【C1】______. although the evidence until now has been anecdotal(轶事的).
    But researchers at the University of Luebek in Germany have designed an experiment that shows a good night’s sleep can【C2】______insight and problem-solving. Dr. Jan Born, a neuroscientist at the university, and his team taught volunteers two simple rules to help them【C3】______a string of numbers into a new order. There was also a third,【C4】______rule, which could help them increase their speed in solving the problem. The researchers divided the volunteers into two groups: half were allowed to sleep after the training while the【C5】______were forced to stay awake. They noticed that the group that had slept after the training were twice as【C6】______to figure out the third rule as the other group.
    "You have a memory representation in your brain of the problem you want to solve, and then you sleep. Sleep can act on the problem," Born said in a telephone interview. But he also admitted that how restructuring of memories occurs or what governs it is still【C7】______.
    Other scientists say the【C8】______evidence supports the anecdotal suggestions that sleep can stimulate creative thinking.
    Although the role of sleep in human creativity will【C9】______be a mystery, the research gives people good reason to【C10】______respect their periods of sleep.
A)hidden I)uninvented
B)experimental J)still
C)fully K)unknown
D)remainder L)reminder
E)strengthen M)convert
F)manageable N)improve
G)complex O)likely
H)prevent
【C5】
选项
答案D
解析 由two groups：half were allowed…和下句的the group…the other group可知，空格处与下句中的the other group指的应是同一个组，本空所填词应表示“另一组或剩下的那组”之义，备选项中只有D)reminder“余下部分，剩下的人数”符合要求，故答案为D)reminder。
