OG第一题

Andrewlzh

">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.
Th
e neuroscientist’s statements, if true, most strongly support which of the
fo
llowing conclusions?
(A) At least some animals perfectly recall every detail of at least some past
experiences.
(B) Perfectly recalling every detail of all their past experiences could help at
least some animals react more appropriately than they otherwise would to
new situations they encounter.
(C) Generalizing from past experiences requires clear memories of most if
not all the details of those experiences.
(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.

这是OG的第一题，稍微有点疑问的就是B选项，我地理解为，完美的回忆起细节才对一些动物有帮助，所以B选项否认了概括的记忆对动物也有帮助。不知道这样理解是否正确。
第二个疑问就是语法问题！！！求大神解救，E选项怎么会出现“would to situation”这样的结构，没见过啊！！！求普及

你的第一个问题看出你学习GMAT不久，还没找到CR题应该怎么做的技巧。这题是归纳推理，直接去原文找逻辑关系，然后看选项中的逻辑关系是否与原文中的一致，多数情况下选项都是充分必要条件颠倒，或者是原推理关系的非等价变换，或者是原文中根本么有涉及的范围。把这些错误选项都排除，剩下的那个就是正确选项。
B的主要错误是这是一个文中根本没有提及的逻辑关系，文中第二句话只说了perfectly recall every detail of all their experiences不是help animals react appropriately to situations they encounter的必要条件。至于是不是充分条件，题干跟没没说，所以B选项无法直接从题干推出来。故B错。
我们只看factors之间的逻辑关系，不看句子的具体内容。

第二个疑问你断句有问题：than they otherwise would 停
to是跟react搭配的

看得出来你现在甚至连GMAT的很多基础知识都还不掌握，问题太早了。
我建议你先过一遍OG和prep之后再来问题，很多疑问随着你的能力上升都会自己理解，没必要问。

你好 我想问下这题的B选项，og中的解释是：this statement would be false even if all of what the neuroscientist says is true. Even if it were never helpful for any animals to recall every detail of all its past experiences, animals could still benefit by learinging from through generalizations.然后这个和B选项的关系没看懂，求教
