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.


答案是a

个人想法~
prem：1）9 flights cancelled；
      2）on a single day, cancellations caused by mechanical problem ≤ 1 or 2
                  
conc    ：some of the 9 were probably due to something else.

negate+POE
A.判断有关，negate： ≤1 or 2 airplanes were scheduled for the nine canceled flights.  题目中有个隐含条件： 机械故障的飞机≤1 or 2 ，如果这些9次flights都是他们的schedule，那么就deny 结论了。
B.other airlines of the same size 无关
C.longer than the average flight 无关
D.before 无关时间，题目在考虑certain day
E.are based at the same airport. 无关


我怎么感觉这道题和OG上的假设题思路还是有差别呢。。。。

同意楼上 这个假设跟G的有点小出入 这些天偶做逻辑大全倒是碰到不少这种思路的
比如这个
1.     Amail order company recently had a big jump in clothing sales after hiring acopywriter and a graphic artist to give its clothing catalog a magazinelikeformat designed to appeal to a more upscaleclientele. The company is now planning to launch a housewares catalog using thesame concept.
The company’s plan assumes that
(A) otherhousewares catalogs with magazinelike formats do not already exist

(B) an upscale clientele would be interestedin a housewares catalog

(C) the samecopywriter and graphic artist could be employed for both the clothing andhousewares catalogs
(D) amagazinelike format requires a copywriter and a graphic artist（B）
(E) customersto whom the old clothing catalog appealed would continue to make purchases fromcatalogs with the new format

不行就用排除法吧。。
