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?

 

 

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

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

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

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

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

answer (E)

讨论连接里没有。

我觉得没有一个答案能推出来。。。我觉得(E)suffering from hay fever who also have asthma 和题目中people who have asthma also suffer from hay fever是一回事，所以都要大于95%。。。。

谢谢啊~

一个是有HAY FEVER 又有 ASTHMA 的人 和 所有患有 ASTHMA 人比较,

另一个是

有HAY FEVER 又有 ASTHMA 的人 和 所有患有HAY FEVER 的人比较

suffering from hay fever who also have asthma 和题目中people who have asthma also suffer from hay fever 人数相同

但是 所有患有 ASTHMA 人 要比 所有有HAY FEVER 的人少很多 因为 Asthma is much less common ailment than hay fever

明了，分母不同的问题。。。汗

感觉这题有点怪

E似乎也不是很严谨

如果A有100人 H有103

A中有H的有98人

那么98/103=0.951

我的理解有什么问题吗

侬侬

I think the reason is 'Asthma is much less common ailment than hay fever'.

E中的pecentage是谁和谁的比例啊，好像没有讲清楚啊？
