※ 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? ^^^^^^^^^^^^^^^^^ 想像一個大長方型中有兩個部份重疊的圓一個是Asthma 一個是hay fever 兩個圓重疊的部份<people who have asthma also suffer from hay fever> 佔Asthma這個圓的95%以上 Asthma的圓"小於"hay fever的圓<Asthma is much less common than hay fever> Asthma多大不知道 hay fever多大不知道長方型減掉兩個圓的面積也不知 : A) Hay fever is a prerequisite for the development of asthma. 題目給的是比例關係不是因果關係 : B) Asthma is a prerequisite for the development of hay fever. 題目給的是比例關係不是因果關係 : C) Those who have neither hay fever nor asthma comprise less than 5 : percent of the total population. 至少需要長方型跟兩個圓聯集的比例才有辦法推論題目只給了Asthma&hay fever重疊的部份和Asthma的比例 : D) The number of people who have both of these ailment is greater than : the number of people who have only one of them. 需要兩圓重疊部分與Asthma的比例<題目有給> 和兩圓重疊部分與hay fever的比例<題目沒給> 所以無法推論因為搞不好重疊部份只佔0.01%Hay fever 那樣就會推翻這個結論 : 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) 這就簡單多了同樣數量的東西佔Asthma 95% 而Hay fever比Asthma大所以一定小於95% : total population : / ｜ \ : no ailment asthma < < < hay fever : less common : / \ / \ : <5% >95% : only have also have only have : asthma hay fever hay fever : 這是我推導的圖, : 但是卻無法從選項中找到答案＠＿＠ : 針對選項（Ｅ）中的95%是total population的95%嗎？？ : 還請各位GMAT高手幫忙解惑？？謝謝！！ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.166.115.29
