Mr. Janeck: I don’t believe Stevenson will win the election for governor. Few voters are willing to elect a businessman with no political experience to such a responsible public office.

Ms. Siuzdak: You’re wrong. The experience of running a major corporation is a valuable preparation for the task of running a state government.

M. Siuzdak’s response shows that she has interpreted Mr. Janeck’s remark to imply which of the following?

(A) Mr. Janeck considers Stevenson unqualified for the office of governor.

(B) No candidate without political experience has ever been elected governor of a state.

(C) Mr. Janeck believes that political leadership and business leadership are closely analogous.

(D) A career spent in the pursuit of profit can be an impediment to one’s ability to run a state government fairly.（A）

(E) Voters generally overestimate the value of political experience when selecting a candidate.

7. If A, then B.

If B, then C.

If C, then D.

If all of the statements above are true, which of the following must also be true?

(A) If D, then A.

(B) If not B, then not C.

(C) If not D, then not A.

(D) If D, then E.（C）

(E) If not A, then not D.

12.   Are you still reading the other newspaper in town? Did you know that the Daily Bugle is owned by an out-of-town business syndicate that couldn’t care less about the people of Gotham
                        City? Read the Daily Clarion, the only real voice of the people of Gotham
                        City!

Which of the following most directly refutes the argument raised in the advertisement above?

(A) Over half of the advertising revenues of the Daily Clarion come from firms whose headquarters are located outside of Gotham
City.

(B) The Daily Clarion usually devotes more of its pages to out-of-town news than does the Daily Bugle.

(C) Nearly 40 percent of the readers of the Daily Clarion reside outside the limits of Gotham
City.

(D) The editor-in-chief and all the other members of the editorial staff of the Daily Bugle have lived and worked in Gotham
City for ten years or more.（D）

(E) The Daily Bugle has been published in Gotham
City for a longer time than has the Daily Clarion.

第一题选A Janeck说S不胜任，因为没有政治经验

Siuzdak说Janeck错了，S有business experience。（其实就是说S可以胜任）

问，Siuzdak怎么理解J的话的？A J 说S unqualified（不够资格/不能胜任） for the office of governor.

7 选C A推出B ,B推出C，C推出D，——》A推出D

逆否命题=原命题所以 not D——》not A

12、Did you know that the Daily Bugle is owned by an out-of-town business syndicate that couldn’t care less about the people of Gotham
City?

原文的意思是： DB 说因为自己是out-of-town 的杂志，所以他们非常关心the people of Gotham
City因此是真正的voice of the people of Gotham
City

D 直接驳倒原因，原因不成立，就不能推出结果。（D能读懂吧，就不解释了）

以下是引用程雅祺在2007-8-4 11:36:00的发言：

上面的推理过程倒是不难　　可是为什么不选B　　！！　if not B then not C!??

不对,如果你实在要用B和C来比的话,也应该是if not c then not B.先取非，然后推理的尖头掉一个方向才是逆否命题．

从这个角度来讲　　C是推理方式更好一点　　是不是这类题都是这个规律，　先取非再将尖头反向？？

其实如果你非要严格的看逆否关系,直接把高中数学简易逻辑那一套拿过来就行了.逆否逆否,先逆后否,或者先否后逆,都能到达目的.
