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.
The argument above assumes which of the following?
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.
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.
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.
Wealthy individuals who donate money to charitable and educational institutions are the only individuals who donate money to such institutions.
Income tax laws should be changed to make donations to charitable and educational institutions the only permissible deductions from taxable income.
前提：如果法律条款通过，捐款企业将不再享受捐款免税。
结论：慈善和教育机构将不得不关门。
前提与结论有很强的因果联系，且前提时间逻辑上发生在结论之前。判断为因果推理。题目类型为加强，可对选项取非看是否削弱。
A涉及因果且语义上削弱结果，保留。
B比较有迷惑性，语义上涉及因果对象（条款以及慈善教育机构）但将条款放在了状语中，把论元偷换成了donator而非provison，仅描述了捐献者的特点，而未给出削弱或加强的方向，属于常见的迷惑选项。
C描述税法目的，语义上不能削弱结论。
D未涉及provision且描述了donator特征，语义上不能削弱结论。
E涉及因果，但属于一个建议，语义上不能削弱结论。
