A recent report determined that although only 3% of drivers on Maryland highways equipped their vehicles with radar detectors, 33% of all vehicles ticketed for exceeding the speed limit were equipped with them. Clearly, drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly than are drivers who do not. The conclusion drawn above depends on which of the following assumptions? The answer is: drivers who are ticketed for exceeding the speed limit are more likely to exceed the speed limit regularly than are drivers who are not ticketed. 我想问的是,这个问题怎么思考,虽然看了OG的解释,我还是转不过弯来,请教大家解题思路方法。 ----------------------------------------------------------------------------------------------------------------------------------------------------- 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? The answer is: 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. 但是题目中还有两个选项,我看也像答案,而且ETS的解释我不是很明白(黄底标出),请教有没有别的思路。 1. 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. ETS explained that as the argument need only assume that many institutions depend heavily, but not necessarily exclusively, on donations from such individuals. 2. Wealthy individuals why donate money to charitable and educational institutions are the only individuals who donate money to such institutions. Explained by ETS that as far as the argument is concerned, there can be many other individuals who donate money to the institutions.
