GWD-9-Q13:

Fact: Asthma, a bronchial condition, is much less common ailment than hay fever, an allergic inflammation of the nasal passages.

Fact: over 95 percent of people who have asthma also suffer from hay fever.

If the information given as facts above is true, which of the following must also be true?

A.     Hay fever is a prerequisite for the development of asthma

B.     Asthma is a prerequisite for the development of hay fever

C.     Those who have neither hay fever nor asthma comprise less than 5 percent of the total population

D.    The number of people who have both of these ailments is greater than the number of people who have only one of them

E.     The percentage of people suffering from hay fever who also have asthma is lower than 95 percent.

答案是E, 推理过程是" A没有F多发率,而95%的A病人就会有HF, 这证明了HF的更常见性; 而E的答案证明了A的不常见性", 对吗?谢谢回复啦啦!~~~

GWD-9-Q24:

For similar cars and drivers, automobile insurance for collision damage has always cost more in Greatport than in Fairmont. Police studies, however, show that cars owned by Greatport residents are, on average, slightly less likely to be involved in a collision than cars in Fairmont. Clearly, therefore, insurance companies are making a greater profit on collision-damage insurance in Greatport than in Fairmont.

Which of the following is an assumption on which the argument depends?

A.     Repairing typical collision damage does not cost more in Greatport than in Fairmont.

B.     There are no more motorists in Greatport than in Fairmont.

C.     Greatport residents who have been in a collision are more likely to report it to their insurance company than Fairmont residents are.

D.    Fairmont and Greatport are the cities with the highest collision-damage insurance rates.

E.     The insurance companies were already aware of the difference in the likelihood of collisions before the publication of the police reports.

这题也不太想得通, 我选的是E, 因为保险公司知道了G区比F区COLLISION的事故少, 而他们还是收高于F区的保险费, 说明保险公司赚了很多钱在G区上. 请指教!!!

文章没有给出两者是相关的疾病，A和B都不合适，无法推出

E是个数学问题。

文章说保险公司在G收的钱多，而且G的车子牵扯进车祸的可能小，结论说这样，在G赚的钱多

但是如果G牵扯进车祸的车子维修费用都暴贵无比，保险公司要赔付N多钞票，那就完了。在G收的钱都不够赔了。

A是答案。
