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.
Understanding the argument -
A proposed change would eliminate deductions from taxable income.
If this change were adopted, wealthy individuals would no longer be permitted such deductions. (Do not jump to say that this means wealthy individuals do not contribute - that is an assumption that is not stated. What is stated is that they are not permitted. The assumption is if someone is not permitted, they don't do it in light of the conclusion here)
Conclusion - many charitable and educational institutions would have to reduce services, and some would have to close their doors.
The assumption is NOT - Wealthy individuals contribute to the majority of donations.
The assumption for the conclusion is that wealthy individuals DO NOT contribute to the majority of donations in light of the proposed change. (Not the ONLY one)The argument above assumes which of the following?
(A) Without 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. -
Complex options have unnecessarily complicated a simple question. What it is necessarily trying to say is that "at least some wealthy individuals would not donate." in line with our pre-thinking.
It's further complicated by the way we negate options (GMAT knows it, and they just want to raise the bar higher)
The correct negation of "at least some wealthy individuals would not donate" is "None wealthy individuals would not donate," which essentially means "all will donate."
Or the Correct negation of "at least some wealthy individuals would not donate" is "at least some wealthy individuals would donate," which essentially means "at least some will still donate."
In both cases, the conclusion breaks because if all or some are still donating, then "many charitable and educational institutions would not have to reduce services, and some would not have to close their doors."
Incorrect negation - "at least some wealthy individuals would not donate" is "none would donate." This is where this gets complicated as GMAT knows we try to negate every option (which is not a good practice. We should negate the final left or between the final 2 to decide), and this is a trap set by GMAT. (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. -
ONLY source is a problem. We don't need to assume that it's the only source. (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.
Out of scope. (D) Wealthy individuals who donate money to charitable and educational institutions are the only individuals who donate money to such institutions. - ONLY individuals is a problem.
We don't need to assume that these individuals are the only source. (E) Income tax laws should be changed to make donations to charitable and educational institutions the only permissible deductions from taxable income.
Out of scope
