GWD-20

Q14:

Certain politicians in the country of Birangi argue that a 50 percent tax on new automobiles would halt the rapid increase of automobiles on Birangi’s roads and thereby slow the deterioration of Birangi’s air quality.  Although most experts agree that such a tax would result in fewer Birangians buying new vehicles and gradually reduce the number of automobiles on Birangi’s roads, they contend that it would have little impact on Birangi’s air-quality problem.

 

Which of the following, if true in Birangi, would most strongly support the experts’ contention about the effect of the proposed automobile tax on Birangi’s air-quality problem?

 

1. Automobile emissions are the largest single source of air pollution.
2. Some of the proceeds from the new tax would go toward expanding the nonpolluting commuter rail system.
3. Currently, the sales tax on new automobiles is considerably lower than 50 percent.
4. Automobiles become less fuel efficient and therefore contribute more to air pollution as they age.
5. The scrapping of automobiles causes insignificant amounts of air pollution.

Q17:

Of patients over 65 years old who survived coronary bypass surgery—a procedure widely prescribed for people with heart disease—only 75 percent benefited from the surgery.  Thus it appears that for one in four such patients, the doctors who advised them to undergo this surgery, with its attendant risks and expense, were more interested in an opportunity to practice their skills and in their fee than in helping the patient.

 

Which of the following, if true, most seriously undermines the argument?

 

1. Many of the patients who receive coronary bypass surgery are less than 55 years old.
2. Possible benefits of coronary bypass surgery include both relief from troubling symptoms and prolongation of life.
3. Most of the patients in the survey decided to undergo coronary bypass surgery because they were advised that the surgery would reduce their risk of future heart attacks.
4. The patients over 65 years old who did not benefit from the coronary bypass surgery were as fully informed as those who did benefit from the surgery as to the risks of the surgery prior to undergoing it.
5. The patients who underwent coronary bypass surgery but who did not benefit from it were medically indistinguishable, prior to their surgery, from the patients who did benefit.

同意mbz，这两个题是没有争议的

Q14

D, Automobiles become less fuel efficient and therefore contribute more to air pollution as they age.        随着车时间的增加会发出更多的污染,这是新车和旧车的比较,

E,The scrapping of automobiles causes insignificant amounts of air pollution.汽车的残余物带来的不大的环境污染,也在污染总的比例不大,

如果只是在新车和旧车之间的比较,如何理解gradually reduce the number of automobiles on Birangi’s roads, gradually reduce是要经过一段时间的,车不可能总是新车,所以这里要说的不是新车和旧车的比较,而是总量的概念.

如果没有后半句话,那答案D肯定没有问题.

Q17: 我也认为E较好,但是对于D究竟错误在哪里,不是很清楚.请帮办分析D选项的错误之处.

Please take a look at the argument itself:

doctors who advised them to undergo this surgery, with its attendant risks and expense, were more interested in an opportunity to practice their skills and in their fee than in helping the patient.

Now take a look at choice E below:

E) The patients over 65 years old who did not benefit from the coronary bypass surgery were as fully informed as those who did benefit from the surgery as to the risks of the surgery prior to undergoing it.

choice E  does not mention the doctors' interest in skills or money at all, so it is unrelated.

In fact, E even strengthens the argument a little bit by saying that the doctor did not hide anything away from the patients b/c the patients are fully informed before the operations.

Hence, E is not correct.

Q14

的逻辑链是很明显的

加税－－车辆少－－环境污染少

但是：专家们同意的是“加税－－车辆少”，但是不同意“车辆少－－污染少”

找一个东西能加强“车辆少－－污染未必少”

D：时间长了老车的污染增加了。ok。车辆虽然少，污染还是多

E：汽车的残余物带来的不大的环境污染,insignificant 无关紧要的，可以忽略的。反而加强了“加税－－车辆少”

一个紧张，D和E写反了.

不过MBZ兄写的是完全正确的：）
