Re: [機經] ＣＲ第14題 哮喘
※ 引述《brilange (~~)》之銘言：
: Fact: Asthma, a bronchial condition, is much less common 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 ailment 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.
: 網友分享答案是(E)
這題是GWD-18-Q15
我一開始也做錯,但看到有人分享的解法就懂了 這樣想就很好理解:
E選項 把兩者都有的人數設為X，X/A=95%,因為A＜H，所以X/H肯定小於95%
其他選項的錯誤:
A.還有5%A沒有H 所以H並非先決條件
B.如果A是H的先決條件,那A至少應該跟H一樣多 但 A<H
C.沒有講到 total population
D.95%A的人有H-->兩者都有的人比A少 所以D錯
希望有幫到你囉:)
