Q14:

Political Advertisement:

Mayor Delmont’s critics complain about the jobs that were lost in the city under Delmont’s leadership.  Yet the fact is that not only were more jobs created than were eliminated, but the average pay for these new jobs has been higher than the average pay for jobs citywide every year since Delmont took office.  So there can be no question that throughout Delmont’s tenure the average paycheck in this city has been getting steadily bigger.

Which of the following, if true, most strengthens the argument in the advertisement?

1. The average pay for jobs created in the city during the past three years was higher than the average pay for jobs created in the city earlier in Mayor Delmont’s tenure.
2. Average pay in the city was at a ten-year low when Mayor Delmont took office.
3. Some of the jobs created in the city during Mayor Delmont’s tenure have in the meantime been eliminated again.
4. The average pay for jobs eliminated in the city during Mayor Delmont’s tenure has been roughly equal every year to the average pay for jobs citywide.
5. The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city.

Q15:

Capuchin monkeys often rub their bodies with a certain type of millipede.  Laboratory tests show that secretions from the bodies of these millipedes are rich in two chemicals that are potent mosquito repellents, and mosquitoes carry parasites that debilitate capuchins.  Some scientists hypothesize that the monkeys rub their bodies with the millipedes because doing so helps protect them from mosquitoes.

Which of the following, if true, provides the most support for the scientists’ hypothesis?

1. A single millipede often gets passed around among several capuchins, all of whom rub their bodies with it.
2. The two chemicals that repel mosquitoes also repel several other varieties of insects.
3. The capuchins rarely rub their bodies with the millipedes except during the rainy season, when mosquito populations are at their peak.
4. Although the capuchins eat several species of insects, they do not eat the type of millipede they use to rub their bodies.
5. The two insect-repelling chemicals in the secretions of the millipedes are carcinogenic for humans but do not appear to be carcinogenic for capuchin

这两道题目分别选C，E，可是我觉得这两个答案一点道理都没有，

14题，C怎么能支持结论的Pay Check的Bigger呢？

15题，E关对Human致癌有意义么？

merit

I agree with you, the answers are not correct.

14. D should be the answer, although I first picked A

15. C

leadership

14.题我也选的A

现在大概明白为什么要选D了。原文说"Mayor Delmont created more jobs than he elimitated. Moreover, the average pay for these new jobs has been higher than the average pay for jobs citywide. So there can be no question that throughout Delmont’s tenure the average paycheck in this city has been getting steadily bigger."

But if the average pay for those jobs elimitaed was much higher than the average，the average pay for jobs citywide would be brought down significantly.  As a consequence, the average pay for the new jobs was more likely to be higher than the significantly decreased average pay for citywide.  Therefore, the conclusion in the statement---"So there can be no question that throughout Delmont’s tenure the average paycheck in this city has been getting steadily bigger"--- cannot be guaranteed unless Option D is true--- "The average pay for jobs eliminated in the city during Mayor Delmont’s tenure has been roughly equal every year to the average pay for jobs citywide."

So Option D most strengthens the argument in the advertisement.

15题选C,这个应该比较明显吧
