问题     A device 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【S1】______, although the evidence until now has been anecdotal(轶事的，趣闻的). But【S2】______at the University of Luebek in Germany  have designed an experiment that shows a good night’s sleep can【S3】______insight and problem-solving. Dr. Jan Born, a neuroscientist at the university, and his team taught volunteers two simple rules to help them【S4】______a string of numbers into a new order. There was also a third,【S5】______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【S6】______were forced to stay awake. They noticed that the group that had slept after the training were twice as【S7】______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【S8】______of memories occurs or what governs it is still unknown. Other scientists say the【S9】______evidence supports the anecdotal suggestions that sleep can【S10】______creative thinking. Although the role of sleep in human creativity will still be a mystery, the research gives people good reason to fully respect their periods of sleep.

选项
答案F)
解析 形容词辨义题。空格处单词前面有appear和比较级more修饰，与句子前面的insurmountable的意思相对，需要填入形容词。该句意为：一夜安眠之后，原本似乎难以克服的问题往往就显得好办一些了。 manageable(可处理的)与insurmountable(不能克服的)相响应。
