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.
