题目：
Neuroscientist: Memory evolved to help animals react appropriately to situations they encounter by drawing on the past experience of similar situations. But this does not require that animals perfectly recall every detail of all their experiences. Instead, to function well, memory should generalize from past experiences that are similar to the current one.
The neuroscientist’s statements, if true, most strongly support which of the following conclusions?
The neuroscientist’s statements, if true, most strongly support which of the following conclusions?

D、Recalling every detail of all past experiences would be incompatible with any ability to generalize from those experiences.
E、Animals can often react more appropriately than they otherwise would to situations they encounter if they draw on generalizations from past experiences of similar situations.

解析：60%+80%+10%-100%=50%，即会英语和会法语中都有会两个都会的人，重复计算了该部分，故而减去100%就是两个都会的比例
答案：50%
