张老师，这个你那个阅读课里面第十二篇文章。关于是不是细节我处理出了点问题，文章第三段，第一句是k仔细检查了失业模型。第二句是他发现了失业率因阶级而异。第三句是但是这特定阶级内部的失业率影响也不同。第四句即使是在同一个trade里，失业率也不同，confirm里前一句。第五局k用these differential rates 去帮助解释困惑历史学家的现象，这里为什么不是下层细节呢？这句话核心语义是在于“用他的结论去做了件什么事”，并不影响主旨“他的这个结论是什么？”？第六句“但是mobility 不是主要的工人策略”，这里不知道mobility是什么，就返回上一句去看，看见出现在上一句，就觉得在解释上面下沉细节里面的内容是细节转折也就跳了这句。最后一句说的是自救，切入角度小，不读。所以根本没有读出作者在这里还对k怼了一句。这样处理不可以吗？但就是由于这样处理，也就没有读出最后一句前半部分为什么要说尽管还要花很多时间发展应用，这里就没有扣上。。。但实在不懂怎么知道那里就要去读了，感觉有点后面逻辑没有连得上，所以再说服自己该回去读那里的感觉，第一遍读的时候根本对这里没有感觉是逻辑转到了在说他的结论的应用。

这题完全不知道怎么做，看了答案也没明白

我觉得我的问题是自己做的时候思路不是很清楚。 我现在有上十月份的机经班，然后我在跟着老师分析的时候我就是比较清楚，然后正确率就比我平时自己做的时候高很多。 我平时做prep之后也会听自主答疑，然后找问题的思路，但是对自己没有很深入。我要怎样才能就是让思路变得更清晰一点呢？ 因为我是大四在读学生，平时除去上课时间，晚上有时间还有平时抽出来的时间可以复习GMAT. 然后我还有一个月就考试了，然后我制定了一下计划，希望老师帮我改一下。 1. 再重新看一遍OG,着重看讲解，搞懂里面的语法讲解，总结出OG里面的语法知识和做题思路。用一个星期。 2. 每天练一篇OG的阅读精读和作文。 3. 第二个星期专项练习 CR, RC,SR,PS,DS. 4. 第三个星期做PREP和GWD， 然后做专项分析。 5. 第四个星期做计时的全 GWD set，模考当天考试的情况，找出这个考试当时可能会出现的问题。

不懂这题的逻辑，求解！ Kernland imposes a high tariff on the export of unprocessed cashew nuts in order to ensure that the nuts are sold to domestic processing plants. If the tariff were lifted and unprocessed cashews were sold at world market prices, more farmers could profit by growing cashews. However, since all the processing plants are in urban areas, removing the tariff would seriously hamper the government’s effort to reduce urban unemployment over the next five years. Which of the following, if true, most seriously weakens the argument? A. Some of the by-products of processing cashews are used for manufacturing paints and plastics. B. Other countries in which cashews are processed subsidize their processing plants C. More people in Kernland are engaged in farming cashews than in processing them. D. Buying unprocessed cashews at lower than world market prices enables cashew processors in Kernland to sell processed nuts at competitive prices. E. A lack of profitable crops is driving an increasing number of small farmers in Kernland off their land and into the cities.

Since February, the Federal Reserve has raised its short-term interest rate target five times, and (because of the economy's continued strength, analysts have been predicting for weeks that the target will) be raised again in Novermner.

When people engage in activities that help others, their brain releases endorphins, the brain’s natural opiates, which induce in people a feeling of well-being. It has been suggested that regular release of endorphins increases people’s longevity. And a statistic on adults who regularly engage in volunteer work helping others shows that they live longer, on average, than adults who do not volunteer. However, that statistic would be what we would expect even if volunteering does not boost longevity, because___________ Which of the following most logically completes the argument? A In the communities studied, women were much more likely to do regular volunteer work than men were, and women tend to live longer than men do B The number of young adults who do regular volunteer work is on the increase C The feelings of well-being induced by endorphins can, at least for a time, mask the symptoms of various conditions and diseases, provided the symptoms are mild D It is rare for a person to keep up a regular schedule of volunteer work throughout his or her life E Some people find that keeping a commitment to do regular volunteer work becomes a source of stress in their lives 错选了C，答案给的A。A说女士比男士更可能做志愿活动，女士比男士活得长。这不是支持原文了么？可以题目不是应该驳斥吗？
