GWD6-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?

A. 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.

B.Average pay in the city was at a ten-year low when Mayor Delmont took office.

C.Some of the jobs created in the city during Mayor Delmont’s tenure have in the meantime been eliminated again.

D.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.

E. The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city

这题的答案是C, 我选的D. 不明白为什么选C, 请指教

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.

这题我选了C, 答案是E, 不明白，总觉得答案有问题

14题同意D.

猴子用millipede来擦背, millipede里有防止蚊子的DD,而这个DD会使猴子得病.因此假设说猴子用millipede这玩意的目的是保护自己防止蚊子.

支持,C是迷惑的，

The capuchins rarely rub their bodies with the millipedes except during the rainy season, when mosquito populations are at their peak.

虽然雨季的时候猴子大量使用millipedes的确可以说明猴子使用millipedes的目的是防蚊子,但是前面说非雨季的时候猴子很少使用millipedes就不对了，雨季的时候蚊子的数量最多，没有说非雨季的时候就没有蚊子啊，还是有蚊子,但是猴子却几乎不用millipedes了。要么无关，要么削弱。

E.The two insect-repelling chemicals in the secretions of the millipedes are carcinogenic for humans but do not appear to be carcinogenic for capuchins.

这玩意对猴子是无害的，应该说是一个排除他因的加强。配合文章的事实,很好的巩固。

E的加强没有C中的一点好，但是C里又有加强又有削弱，所以还是E更好。

我还是觉得C更好，它是直接加强假设的。 E绕的太远了，就算是抓痒痒对猴子无害，也不能证明它是为了防蚊子。

14 同意为D

15同意为C

求确认....

请讲一讲为什么14选择D阿，D哪里起了加强作用啊

你做的答案都对。第一题：如果被搞掉的那帮家伙的工资极低无比，把原来的整个平均工资拖的低低的，把他们搞掉后，歘的一下，平均工资飞升，就是新增工作的工资不比原来平均工资高，也是虚假繁荣。

第二题：不下雨不蹭痒，为什么？因为蚊子在不下雨天少呀，不叮不痒嘛。下雨多，蚊子多，痒，蹭，多好的建立联系，这就是桥梁呀。

逻辑切忌想的太复杂。坚信第一感觉（当然要正确）

14.

D: eliminate pay =  ave pay；同时证明，留下的工作，pay＝ave pay

题目说：新增的工，pay(设$80)>原来的average（设$50）；

假设新工，占50％，没被eliminate的占50％

average pay ＝ $80×50％＋$50（此处是指原先存在且没有被eliminate的pay）×50％＝$65>$50(原来的ave pay)
