标题: OG10的assumption题搞不懂要怎么取反
og_10_195

A proposed change to federal income tax laws would eliminate deductions from taxable income for donations a taxpayer has made to charitable and educational institutions. If this change were adopted, wealthy individuals would no longer be permitted such deductions. Therefore, many charitable and educational institutions would have to reduce services, and some would have to close their doors.

税法改变→有钱人不能捐款→慈善机构倒闭

The argument above assumes which of the following?

(A)Without the incentives offered by 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 donations because 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 adopting the proposed change in the federal income tax laws cited above is to protect wealthy individuals from having to pay higher taxes.

(D) Wealthy individuals who donate money to charitable and educational institutions are the only individuals who donate money to such institutions.(A)

(E) Income tax laws should be changed to make donations to charitable and educational institutions the only permissible deductions from taxable income.
A答案的some wheathy institutions不是不够persuasive吗？还有B答案说了这些慈善机构的来源只能透过捐款为什么不对呢？

我认为是这样的。

税法改变→有钱人不能捐款或停止捐钱→慈善机构倒闭
（前提）（假设）（结论）

A) 正确。不太明白为什么some 就不persuasive了。。结论说many charitable and educational institutions would have to reduce services, and some would have to close their doors。一切有钱人不捐钱了，导致很多减少服务，一些关闭。

B) 错在了它只说了一个possible fact. 而不是假设。B只告诉你有些慈善的唯一来源是有钱人的捐款。没了。。。没告诉你说有钱人会不会停止捐款。so，推不倒结论。

但是B中说了很多慈善机构的资金唯一来源是人们的捐款，题目假设就说了有钱人不能捐款，那不是没有资金来源了么？？A的some是一些慈善机构会这样做，那不是只是少数概率吗？还是不懂啊~~

我是不是钻牛角尖了

Negate A (get rid of not), then it will become "Without the incentives offered by federal income tax laws, at least some wealthy individuals would donate as much money to charitable and educational institutions as they otherwise would have"
It means some wealthy individual will remain their donations, therefore, some charity or educational institution wouldn't have to close their doors.

我认为题目说的是，捐款的人减少，慈善机构倒闭，所以建议产生税法来阻止捐款人减少。
A取非：即使没有税法，人们依然会捐款。从而削弱了题目。即A为正确答案。
