请问王文静老师这题的解题思路，谢谢老师

换成了word文档。

老师，我报了7月22号，6月底打算根据模考成绩决定是否改考到7月5号，暂时按照5号考试制定26天计划。我做题的大体情况如下：去年10月份做过OG，并且按照学霸方法总结过。。上一周按照博智新的方法重新把OG所有verval做了1遍又着重解题思维复习了2遍，又把发的习题册做过的全部复习2遍，在做题的时候有感觉到跟以前的思维不一样。做题感觉有些上道了哈哈~~ 今天结束了OG，明天开始GWD，刚做出了计划，望老师指点。

According to a theory advanced by researcher Paul Martin，the wave of species extinctions that occurred in North America about 11,000 years ago，at the end of the Pleistocene era，can be directly attributed to the arrival of humans，i.e.，the Paleoindians， who were ancestors of modern Native Americans. However，anthropologist Shepard Krech points out that large animal species vanished even in areas where there is no evidence to demonstrate that Paleoindians hunted them.Nor were extinctions confined to large animals： small animals，plants，and insects disappeared，presumably not all through human consumption. Krech also contradicts Martin's exclusion of climatic change as an explanation by asserting that widespread climatic change did indeed occur at the end of the Pleistocene. Still，Krech attributes secondary if not primary responsibility for the extinctions to the Paleoindians，arguing that humans have produced local extinctions elsewhere.But，according to historian Richard White，even the attribution of secondary responsibility may not be supported by the evidence. White observes that Martin's thesis depends on coinciding dates for the arrival of humans and the decline of large animal species，and Krech，though aware that the dates are controversial，does not challenge them；yet recent archaeological discoveries are providing evidence that the date of human arrival was much earlier than 11,000 years ago. 　3. In the last sentence of the passage， the author refers to “recent archaeological discoveries” (lines 27-30) most probably in order to 　　(A) Refute White's suggestion that neither Martin nor Krech adequately account for Paleoindians' contributions to the Pleistocene extinctions 　　(B) Cast doubt on the possibility that a more definitive theory regarding the causes of the Pleistocene extinctions may be forthcoming 　　(C) Suggest that Martin's， Krech's， and White's theories regarding the Pleistocene extinctions are all open to question 　　(D) Call attention to the most controversial aspect of all the current theories regarding the Pleistocene extinctions 　　(E) Provide support for White's questioning of both Martin's and Krech's positions regarding the role of Paleoindians in the Pleistocene extinctions 老师，我在做这道题的时候，首先定位到最后一句觉得没说什么重点，就有个yet转折，可能这是用来驳斥前面的某些观点的。所以看选项找有没有驳斥的意思的， 发现5个选项全都在驳斥。。。心里慌了往前找。再回去找的时候时间已到。我就随便选了个B（时间一到各种混乱），因为在做这篇文章之前，我大体看了下原文，记住了原文讲的是P反驳M，W反驳P。后来答案我也看明白了，我认为我做这道题的思路出现了偏差，我想问一下应该怎么修正。

本人到现在已经考了很多次考试，但是还是没有考出来。打算下个月再考一次。写了一个大概的复习计划，希望老师能提下建议。谢谢！

英老师， 你好。我多年前有过3次考gmat的经历，并且都末上700。个人认为最薄弱环节是SC，没有太好的语感，现制定了一套50天的复习计划（详见附件）。由于在职工作较忙，所以每天估计只有2-3小时的复习时间，报的7月底的考试，目标710以上。 谢谢老师！

报了617的考试，一战，关于复习计划有一些问题想请教英老师： 1.我考试时间应该是刚刚换库的时候，我平时做GWD数学一般错误不超过5个，这一个多星期数学应该怎样复习？请问是否有必要看前一个月的数学机经，以及怎样有效利用数学机经？ 2.刚刚开始做GWD模考，才做了4天，请问老师能否详细讲讲每次做完模考以后REVIEW的方法，是先把错误的题全部重做，再听答疑，还是每道题都听解释，尽可能吃透，或者是否有其他建议？谢谢！

Vasquez-Morrell Assurance specializes in insuring manufacturers. Whenever a policyholder makes a claim, a claims adjuster determines the amount that Vasquez-Morrell is obligated to pay. Vasquez-Morrell is cutting its staff of claims adjusters by 15 percent. To ensure that the company’s ability to handle claims promptly is affected as little as possible by the staff cuts, consultants recommend that Vasquez-Morrell lay off those adjusters who now take longest, on average, to complete work on claims assigned to them. Which of the following, if true, most seriously calls into question the consultants’ criterion for selecting the staff to be laid off? (A) If the time that Vasquez-Morrell takes to settle claims increases significantly, it could lose business to other insurers. (B) Supervisors at Vasquez-Morrell tend to assign the most complex claims to the most capable adjusters. (C) At Vasquez-Morrell, no insurance payments are made until a claims adjuster has reached a final determination on the claim. (D) There are no positions at Vasquez-Morrell to which staff currently employed as claims adjusters could be reassigned. (E) The premiums that Vasquez-Morrell currently charges are no higher than those charged for similar coverage by competitors.
