今天小编为大家带来了新版GMAT考试官方指南中的个别新题讲解，当然，很多题目大家可能已经思考了很多，看看今天小编带来的新版OG2016中GMAT逻辑的那些“鲜货”合不合你的胃口吧。
It is widely assumed that people need to engage in intellectual activities such as
solving crossword puzzles or mathematics problems in order to maintain mental
sharpness as they age. In fact, however, simply talking to other people—that is,
participating in social interaction, which engages many mental and perceptual
skills—suffices. Evidence to this effect comes from a study showing that the more
social contact people report, the better their mental skills.
Which of the following, if true, most seriously weakens the force of the evidence
cited?
(A) As people grow older, they are often advised to keep exercising their
physical and mental capacities in order to maintain or improve them.
(B) Many medical conditions and treatments that adversely affect a person’s
mental sharpness also tend to increase that person’s social isolation.
(C) Many people are proficient both in social interactions and in solving
mathematical problems.
(D) The study did not itself collect data but analyzed data bearing on the
issue from prior studies.
(E) The tasks evaluating mental sharpness for which data were compiled by
the study were more akin to mathematics problems than to conversation.
题干很简单，完全读懂了，但是这个答案的逻辑弄不清楚，正确选B。是这样解释的
B Correct. This provides evidence that the correlation observed in the
study results from mental sharpness facilitating social interaction, in which
case the study results do not indicate that social interaction facilitates
mental sharpness.
因果推理找削弱
前提(因)：the more social contact people report, the better their mental skills.
结论(果)： simply talking to other people suffices to maintain mental sharpness as they age
因--->果 需要建立在一个Assumption之上：“因”必须可以发生!或者没有其他因素阻止“因”发生
举例：
只要我明天GMAT考800分，足以保证我上哈佛。
如果你“突然”发现你不认识英文啊!明天GMAT考800分可能发生吗?如果不可能发生，但你还要上哈佛，那么你是不是要采取别的手段?比如“突然”发现基辛格是我爹铁哥们!
如果你通过基辛格推荐上了哈佛，是不是不是单单通过“明天GMAT考800分”达到这个目的的呢?那你还能说“明天GMAT考800分”是你上哈佛的“唯一充分条件”吗?
这题的意思就是这些老头老太太常吃的药或者治疗会让他们根本无法正常交流，那不做数学题或者玩点别的维持智商，就等老年痴呆啊。
