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 capuchins.
   

Answer:
答案怎么是E呢？

14题：新工作工资>平均值（题干）    去掉的工作工资=平均值（D选项）  且新工作的数量还>去掉的工作 （题干）

所以大家的平均收入肯定提高了

Q14.如果失去的工作的平均工资保持不变，而新增工作的平均工资增长，而新增的工作岗位又多余失去的工作岗位，那最后的结果就是平均工资水平增高。但是如果失去的工作的工资随着新增工作的工资的增长而增长，那结果可能是总体工资水平保持不变。

yvonnechen88

我也觉得14题选D。。。。。工资整体的升高不是因为裁去了那些低收入的职业才升高的，而是新的工作工资上升，拉动整体上升了。

15题C的意思是猴子除了在蚊子盛行的雨季之外几乎不用millipede来挠痒痒，那说明millipede针对的就是蚊子啊，原文中也说猴子用millipede挠痒痒可以驱蚊，支持了原文啊。。。。。我觉得就应该是C吧。。。。

rainbowmanutd

15是C吧。、

我再看了下题，我觉得14题还是应该选D嘛，第一句话不是结论，最后一句才是！楼主请告诉我答案

guanghenry

14题是选C，因为文章第一句话才是结论！！只有C是加强他的结论的！

whx1862

我觉得也应该是C，你说的对，但是答案确实是E，没有看错，也许答案写错了？
