Smithtown University’s fund-raisers succeeded in getting donations from 80 percent of the potential donors they contacted. This success rate, exceptionally high for university fund-raisers, does not indicate that they were doing a good job. On the contrary, since the people most likely to donate are those who have donated in the past, good fund-raisers constantly try less-likely prospects in an effort to expand the donor base. The high success rate shows insufficient canvassing effort.
Which of the following, if true, provides more support for the argument?
分析A选项
分析B选项
分析C选项
分析D选项
分析E选项

A s大学新增的捐赠者和别的大学一样,S大学整体捐赠情况好,说明大多数来自于以前的捐赠者,不能说明募集者的工作好
B 新捐赠者比旧捐赠者捐的还多,削弱
C 不是通过募集者联系得到的,无关信息
D 大多数来自于从未捐赠过的人,说明是新的,削弱
E 超过一半的钱都来自于从未捐过款的人,说明是新的,削弱
就一句话可以排除BCDE, 文中说的success rate是80 percent of the potential donors,是对于人的成功率,但是BCDE说的percentage都是有多少捐款来自于之前捐过的人。是捐款的百分比。所以都是无关选项。因为不排除之前没捐过的新的捐款人每个捐的很少但是人数很多。所以只有人数代表成功率。

1.该题争议的根源在于错误理解了原文的结论和不合理的推理(或者称加进自己的信息)。从原文得出的东西必须是MUST BE TRUE,而不是POSSIBLY TRUE 2。该题的结论是:80%的成功率不能说明他们工作做得好(不是:他们工作做不好)。即割断80%成功率对工作做得好的证明力。至于最后一句话是一个补充,因为该句很模糊。 3。A提供的信息仅限于S大学的RAISERS在NEW DONORS方面和其他大学的RAISERS做得差不多好,并没有突出的地方(本身或和原文结合不能说明80%中OLD DONORS比例较大或反之,比如刚开始NEW DONORS总是多,总之,80%中NEW DONOR 和OLD DONORS那个占的比例大是不知道的。这是典型的加进自己信息) 4。 A对结论的支持表现在:工作做得好,原文提供的标准是EXPAND DONOR BASE(即扩展NEW DONORS)。这方面S大学和他大学的RAISERS差不多(根据A),这80%中,高出别人的部分是OLD DONORS的,而根据原文的标准,这部分不能说明工作做得好。所以这exceptionally high 的80%,按照原文的好的标准,其实和其他大学一样,比如他是70%成功率(在说明工作做得好方面,也就是NEW DONORS方面),其它他大学也是70%,所以你不能用80%来证明S大学的RAISERS工作做得好,即支持结论。 5。选项中C为无关项,BDE为WEAKEN。C意思为OLD DONORS中,多数不用CONTACT便捐款。对OLD DONORS是否需CONTACTS才捐款和原文没关系(不能推出RAISERS没努力) #C#选项的无关实际表现在:往坏了说它是Out of Scope的;往好了说在它仅加强了前提,而非结论。 因为所有的GmatCR题前提和结论都有Gap,没有作用在这个Gap上的选项都是无关的。原文前提是说因为大学里的一个普遍现象是donators如果have donated了,他们就会更容易donate。所以好的Found riser都会尽量去找之间没有donate过的人。原文结论是说尽管在所有的联系到的donators中有80%的成功捐款率,大学的found riser not necessarily were doing a good job. 这个前提和结论的Gap是一个Assumption,作者假设了S大学的found riser可能并没有去找新的donator,而是在原来已经有过捐款行为的donator中进行了contact。 如果支持,就证明作者的假设成立就可以。这是所谓的作用在GAP上。 反观C的处理方式:C说 most of the donors are Old Donators without contract . 原文讨论的success标准的 SCOPE是在 Contact之后的成功率下, C实际是out of scope的。 进一步来说 C的出现并没有证实作者的假设。它仅是证实了的确捐过钱的校友更容易捐款。多了一个不用联系都能捐款并捐了大多数款的信息,这个信息对于前提和结论的Gap没有任何影响。 像C这样的还有A certain cultivated herb 一题中的D选项。原文的Gap是有相关到因果之间的推理。D仅是加强了前提中植物氨基酸可以使土壤的有毒物质失活的作用。并不能充分推导出植物能够存货在有毒土壤就是因为氨基酸而不是其他因素。

A是说 这个学校的rasier和其他学校的raiser在完成使不捐款的人捐款这一任务的成功率是一样的,这就说明rasier的真实efficiency是一样的。 were是前面的su'sfund-raisers were about as frequently as were fund-raisers for other universities

同意,正确答案是C。C是说大部分的捐赠者以前就捐过,而募集者都没有联系过他们,明显说明捐款高不是由于募集工作好啊

判断融资者工作好坏的标准是与新的doners联系而不是联系曾经donate自己的doners,所以该选型与题干无关,排除。

这个分明是个错题,正确答案为C,为什么大家还要拼命的去圆其说呢 这个题目有很多的变异,这个只是其中的一个,先看看题干讲得什么意思:某年的大学的拉赞助的团队从80%左右的客户那里拉来了赞助,但是80%这么高的数字并不能说明他们做出了很杰出的工作,因为真正有竞争力的拉赞助的团队应该去尝试捐助几率更小的客户群,所以不能看捐助的百分率来判断这个团队是否做出了卓有成效的工作,那么问下面的那个选项是加强了这种观点,即那个选项说明这个团队并不是那么的efficient: A选项的本身就有问题,先对他做语法分析:SMithtown universtity的拉赞助的人在和潜在的客户之间的联系过程中是成功的,who引导了定语从句来修饰potential donors,这个定语从句里as frequently as 这个用来做比较的词组,你是想去和potential donors比呢,还是想和主句里的fund-raiser去比呢,如果是前者的话,怎么可以用were,如果是后者,as frequently as怎么可以出现在从句里?

亲,你怕是SC没有学好哦。那个were那么好,是倒装提前了,正常的语序我给你还原一下: Smithtown University’s fund-raisers were successful in their contacts with potential donors who had never given before about as frequently as fund-raisers for other universities were (successful)in their contacts with such people(such很好的指示了前面的那一类potential donors).这句话里面,about 做副词,修饰frequently 表示大约,而frequently做状语,修饰前面主句的successful 的频率。所以as ....as 的结构比较的是两类不同的fund- raisers的成功联系such donors的频率(且大约一样。) 好了,解释完意思之后。咱们再来看为什么A很好?因为,这就证明了,S大学的fund-raisers们虽然收到了80%的看似很好的donations,但是其实他们试图去联系那些从没有donate过的donors的频率和其他学校的差不多(也就是说他们在expand the donor base这件事情上压根儿就没有比别的学校好,甚至有可能比别的学校还差,因为联系了不代表得到donations了。)所以,A简直完美的加强了原文逻辑。

第一,为什么频率差不多=insufficient? 第二,你自己都承认了,联系不等于donation,我们讨论的是donation,和联系多少没关系,是不是无关选项?

A是说 他们和其他大学对那些从来没有捐赠过的人的成功联系是一样的。 既然如此, 他的大学和其他大学的成功率是一样的,但是他的大学却80%那么高,说明是来自于以前捐赠者,他们工作人员自身不给力,甚至更差。
