标题: 两道FEIFEI逻辑,是同一类型的
做FEIFEI是发现这类的CR题很不好理解,有谁能给分析分析的,要是考试遇到了,就知道做法了。

23. On a certain day, nine scheduled flights on Swift Airlines were canceled. Ordinarily, a cancellation is due to mechanical problems with the airplane scheduled for a certain flight. However, since it is unlikely that Swift would have the mechanical problems with more than one or two scheduled flights on a single day, some of the nine cancellations were probably due to something else.

The argument depends on which one of the following assumptions?

(A) More than one or two airplanes were scheduled for the nine canceled flights.

(B) Swift Airlines has fewer mechanical problems than do other airlines of the same size.

(C) Each of the canceled flights would have been longer than the average flight on Swift Airlines.

(D) Swift Airlines had never before canceled more than one or two scheduled flights on a single day.

(E) All of the airplanes scheduled for the canceled flights are based at the same airport.

答案选A

21. Historian: We can learn about the medical history of individuals through chemical analysis of their hair. It is likely, for example, that Isaac Newton’s psychological problems were due to mercury poisoning; traces of mercury were found in his hair. Analysis is now being done on a lock of Beethoven’s hair. Although no convincing argument has shown that Beethoven ever had a venereal disease, some people hypothesize that venereal disease caused his deafness. Since mercury was commonly ingested in Beethoven’s time to treat venereal disease, if researchers find a trace of mercury in his hair, we can conclude that this hypothesis is correct.

Which one of the following is an assumption on which the historian’s argument depends?

(A) None of the mercury introduced into the body can be eliminated.

(B) Some people in Beethoven’s time did not ingest mercury.

(C) Mercury is an effective treatment for venereal disease.

(D) Mercury poisoning can cause deafness in people with venereal disease.

(E) Beethoven suffered from psychological problems of the same severity as Newton’s.答案选B

我是用排除法

首先是簡單理解題目

1. 在某一天 Swift Airlines的九個航班都被取消了, 一般說來 取消的航班通常都因為飛機的機械問題, 因為Swift Airlines 在一天之內有超過一兩架以上的飛機有機械問題的可能性不高, 所以這九個被取消的航班裏的某些航班應該是其他因素所造成
(A) 這是最可能的答案 除非說被取消的九個航班正好都是分別都排定到兩架有問題的飛機的時刻表 不然的話就是這九個航班分別由超過兩個以上的飛機來飛 因為題目說這九個航班裡面的某些航班應是其他因素造成 這句話是根據假設說九個航班分別由兩個以上的飛機來飛才對
(B) Swift Airlines 的機械問題比其他航空公司少 (錯  因為裡面沒有提到任何其他航公公司)
(C) 每個取消的航班都比Swift Airlines的平均航班還要長 (裡面沒提到)
(D) Swift Airlines 從來都沒有在同一天裏取消過一兩個以上的航班 (文裡只有說從來都沒有在同一天裏有超過一兩架以上的飛機有機械問題 因為同一架飛機可能飛不只一個航班 所以就算只有一架飛機有問題 也有可能造成兩個以上航班的取消 所以這個假設是錯的)
(E) 裡面沒有提到 所以是錯的



2. 我也是用排除法
(A) 文中裡面沒有說人體裡的mercury完全不會被排除掉 只有說可以從頭髮裡面測出mercury反應
(B) 在貝多芬的時代 有些人沒有ingest mercury
(C) mercury 是對於 venereal disease很好的治療, 文中只有說mercury在當時是很常見的venereal disease的治療,也可能是當時很有效的治療方式, 但是答案沒有說"在當時" 所以如果(C)成立的話代表說 mercury目前還是很有效的治療方式,所以(C)是錯的
(D) 如果答案是 "mercury poisoning can cause deafness in people" 的話這個答案就成立,但是因為後面又加了 "with veneral disease", 就變成 mercury poisoning 會對於那些有 veneral disease的人造成耳聾,事實上是錯的 因為重點是 mercury poisoning 造成耳聾,而不是mercury poisoning 只對於某些病的人會造成耳聾
(E) 這個比較明顯吧 因為文理並沒有說到任何兩人的比較

所以答案最可能的是 B, 因為在那個時代裡 mercury 是拿來當作治療 veneral disease,所以有些沒有這種病的人 當然很有可能並沒有服用mercury
