Odysseus answered well when the priests showed him a picture of those
who had honored the gods and then escaped shipwreck,and asked him
whether he did not now acknowledge the power of the gods-"Yes,"he
said,"but where are those picutred who were drowned after their
prayers?" And such is the way of superstitions;wherein humans,having
a delight in such vanities,mark the events there they are fulfilled
,but where they fail,though this happens much oftener,neglect and
pass them by.
Which one of the following contains the error of reasoning described
by the author in the passage?
A)I have discovered that Friday the 13th really is a day of
misfortune,Just this past Friday,the 13th,I locked myself out of the
house.
B)Although Napoleon and Alexander the Great were short,Abraham
Lincoln and Charies de Gaulle were tall.So short people seek
leadership in order to overcome feelings of inferiority.
C)Every semester for the past 15 years,an average of 10 percent of
Ms. Elliot's history students have dropped her course before the
exam.So,it seems likely that we can expert 10 percent to drop out
this year.
D)No reliable observer has ever actually seen a yeti.The strongest
evidence seems to be some suspicious tracks.So I think this search
for a yeti is probably a wild-goose chase.
E)I can not trust my lucky shirt any longer,I wore it to the game
today and our team lost.

Ann will either take a leave of absence from Technocomp and return in
a year or else she will quit her job there,but she would not do
either one unless she were offered a one-year teaching fellowship at
a perstigious university.Technocomp will allow her to take a leave of
absence if it does not find out that she has been offered the fellow
ship,but not otherwise.Therefore,Ann will quit her job at Technocomp only if Technocomp finds out she has been offered the fellowship.
Which one of the following ,if assumed,allows the conclusion above to be properly drawn?
A)Technocomp will find out about ann being offered the fellowship only if someone informs on her.
B)The reason Ann wants the fellowship is so she can quit her job a Technocomp.
C)Technocomp does not allow any of its employees to take a leave of absence in order to work for one of its comperitors.
D)Ann will take a leave of absence if Technocomp allows her to take a leave of absence.
E)Ann would be offered the fellowship only if she quit her job at Technocomp.

1.作者段落中描述的推理错误为根据不具备代表性的证据得出了错误的结论.
A)中根据被锁在门外这一意外事件得出5.13日不吉祥,与文中错误一致,为正确答案
B)犯了证据和结论在逻辑上不具相关性
C)用归纳论证法
D)用演绎论证法
E)比较容易误选,虽然用了不具代表性的证据,但得出了正确的结论所以与原文有出入


2.推理为"请假"或者"辞职"->Ann received fellowship
Technocomp没有发现Ann得到fellowship->Tehnocomp允许Ann请假

原文结论 Ann辞职->Technocomp发现Ann得到fellowship

此题偶有点糊涂,不是很明白原文意思,望高手赐教
答案是D

这破题的答案D搞的我糊里糊涂得。D为什么能做“前提假设”?,我觉得推翻它,等于直接与原文的前面所描述的相反,而不是通过原文条件的推理导致结论不成立,这样的选项也正确?
