跟之前問題一樣是看到結果而推原因的類型此題不容易找出跳躍性思考的點那就找排除他因的可能 Asprins reduced heart disease --> participants taking Aspirin less likely to develop heart disease (A) 選項錯誤點有兩個 1. 此題沒討論到 family health history and diet 2. 質疑原本原因 (Aspirin) 的答案為 GMAT 不喜歡的答案類型 (D) 排除樣本不客觀的他因可能如果在吃 Aspirin 之前這些受測者就已經比較不容易得病那看到這樣的結果不一定是 Aspirin 造成的結果所以必須要排除此種可能性另外一種說法是答案 D 為排除因果倒置的可能此題答案選項如同下面網址的題目請參考 http://ppt.cc/wg7l ※ 引述《Metonymia (Metonymia)》之銘言： : In a study of the effects of aspirin on cardiovascular health, : it was found that participants who took aspirin regularly : were signigicantly less likely to develop heart disease than : were other participants. Researchers concluded that taking : aspirins regularly reduced significantly the likelihood of : developing heart disease. : Which of the following is an assumption made by the researchers in : reaching their conclusions? : (A) Factors such as family health history and diet could not affect : the role played by aspirin in diminishing the chances of heart : disease. : (B) Only those participants who were not already at risk for heart : diseases would benefit from taking aspirin regularly. : (C) People who do not take aspirin regularly but engage in healthful : habits and follow healthful diets are less likely to develop : heart disease than are other people. : (D) Those participants who took aspirin regularly were not in better : general health prior to taking aspirin regularly than were the : other participants : (E) Taking aspirin regularly is likely to benefit only the heart and : the circulatory system. : 答案: 遺失... google 我沒找到 : 我的問題是在A跟D之間 : 明顯錯的: : (B) 很有機會罹患心血管疾病的病人, 無關(比較像是條件?要先在題目說的那種) : (C) 健康的習性, 無關 : (E) 阿斯匹靈的好處, 無關 : 搖擺的 : (A) 病人的家族病史和飲食習慣不減輕藥效 : (D) 有吃阿斯匹靈者並沒有先天上比沒吃阿斯匹靈者健康 : D看起來很像是assumption的原因是他有考慮到對照組跟實驗組, : 兩者先決條件不能差太多, 才能歸因是aspirin的療效. : 可是為什麼A不能呢? A雖然沒有像D明確點出有吃藥跟沒吃藥的兩組, : 但也是在強調病人本身的身體素質(家族史)不能干擾藥效 : (不知道是不是像D大說的, 屬於support @@ 為什麼人總會在同樣的地方跌倒呢?) : 希望可以幫忙解答, 謝謝!! -- Dounts GMAT 資訊網站: http://ndxica.pixnet.net/blog -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 111.248.213.42 ※ 編輯: dounts 來自: 111.248.213.42 (06/13 21:04)
