标题: 请教一道prep cr题！！
先直接贴上题目和官方解释：
A proposed change to federal incometax laws would eliminatedeductions from taxable incomefor donations a taxpayer has made to charitable and educational institutions. If this change were adopted,wealthy individuals would no longer be permittedsuch deductions. Therefore, many charitable and educational institutions would have to reduce services,and some would have to closetheir doors.
The argument above assumes which of the following?
A. Without the incentives offeredby federal income tax laws, at least some wealthy individuals would not donate as much money to charitable and educational institutions as they otherwise would have.
B. Money contributed by individuals who make their donationsbecause of provisions in the federal tax laws provides the only source of funding for many charitable and educational institutions.
C. The primary reason for not adoptingthe proposed change in the federal incometax laws cited above is to protectwealthy individuals from havingto pay higher taxes.
D. Wealthy individuals who donate money to charitable and educational institutions are the only individuals who donate money to such institutions.
E. Income tax laws should be changed to make donationsto charitable and educational institutions the only permissible deductions from taxable income.
Reasoning
What must be true in order for the given information to justify the conclusion that the proposed change in tax laws would force charitiesand schools to reduce servicesor dose down? The passagestates only one premise: that the changewould deny wealthyindividuals tax deductions for contributing to charities and schools. To reach the conclusion from this premise, the argumentimplicitly assumesthat denying the wealthy individuals the tax deductions would reducetheir contributions to many charities andschools; that reduced contributions from wealthy individuals wouldreduce overall revenues for many charitiesand schools; and that reduced revenues would force many charitiesand schools to reduce services or close down. Considerthe answer optionsand find one that statesor follows from one of these assumptions.
A. Correct. This follows from the first implicit assumption mentionedabove, that denying wealthy individuals the tax deductions would reduce their contributions to many charities and schools.
B. This need not be true. Even if all charities and schools get some money from sourcesother than these contributions, many charities and schoolsmight still depend mainly on the contributions.
C. The argument does not addressthe motives behind the proposed change, only its likely effects.
D. Even if poorer individuals also donate money to these institutions, the bulk of the donations may come from wealthy individuals.
E. The argument does not discusshow the tax laws should be changed,only the likelyeffects of the proposed change.
这题A是可以选出来，但请问BD为什么错呢？我对这种assumption真的好头晕。。CR是整个V里面最难的我感觉，虽然上次考试CR分最高，但应该不少得益于机经。最近狂看Nature上的科学杂志，看阅读有了明显提示，但读起CR的句子真的毫无抵抗力啊。。还有几天考试了，求急救

我又想了一下，好像有点明白，不知道这样想可以：
assumption的意思就是，没有这个assumption，原文情况就不成立，即选项取反后，原文dies
A：如果这帮人还是会捐钱，那么charities根本就不会有影响，因此原文dies
B和D：是否是唯一来源没关系，取反：非唯一来源，但有了这么一个政策，这帮捐钱人的人确实受到了影响，原文里说的reduce service成立
但是我怕考试中头脑一片浆糊，根本没有这个头脑。这个月13号那场我做V做到后来头都是浆糊状态，没法思考。。

在一堆机经中看到请教prep的，建议楼主发到逻辑版里去，放这可能真是比较少人会回答。
想帮助你来着，这道题我做过，但是我脑子现在也浆糊了。。。一站时候，后来也是觉得好累，一觉得累成绩很快就下来了。。。
不好意思，没帮到你

谢谢你的回答和提议，没关系
我还有几天就考试了，cr是我最担心的。。因为句子真的好绕。
作者: canlan 时间: 2015-11-29 23:54
嗯。。同感。。。cr的句子不比阅读有的句子简单，真的绕来绕去。。。有时候问题都要看半天。。稍不注意就理解错。。。一个单词不认识可能就是全盘错。。。我在这个上面也不稳定，时好时坏。。。。还有几天就二战了，一起加油~~~！

官方解释已经很清楚了。即使按BD所说那些人是唯一来源，也没说是捐多捐少。只有A说了，钱会大大减少。文章倒数第一句和倒数第二句逻辑不连接，有个gap，“钱会减少”能补充上。

明白，谢谢你的解释~~~我之前按GWD的方法有时读不出这种gap的时候就按strengthen题去做，感觉这种方法有时候不行。。

我在KM查了下这道题，评论说出的不好，不符合正常gmac出题，所以你别纠结了。祝考场上看到的都是能一眼看出答案的！
