14. The commissioner has announced that Judge Khalid, who was on the seven-member panel appointed to resolve the Amlec labor dispute will have sole responsibility for resolving the Simdo labor dispute. Since in its decision the Amlec panel showed itself both reasonable and fair, the two sides in the Simdon dispute are undoubtedly justified in the confidence they have expressed in the reasonableness and fairness of the arbitrator assigned to their case.
Which one of the following contains flawed reasoning most parallel to that contained in the passage?
(A) Representing the school board. Matein Barthes presented to the school's principal a list of recently elected school board members. Since only an elected member of the school board can act as its representative. Ms. Barthes's name undoubtedly appears on that list.
(B) Alan Caldalf, who likes being around young children, has decided to become a pediatrician. Since the one characteristic common to all good pediatricians is that they like young children. Mr. Caldalf will undoubtedly be a very good pediatrician.
(C) Jorge Diaz is a teacher at a music school nationally known for the excellence of its conducting faculty. Since Mr. Diaz has recently been commended for the excellence of his teaching, he is undoubtedly a member of the school's conducting faculty.
(D) Ula Borg, who has sold real estate for Arcande Realty for many years, undoubtedly sold fewer houses last year that she had the year before since the number of houses sold last year by Arcande Realty is far lower than the number sold the previous year.
(E) The members of the local historical society unanimously support designating the First National Bank building a historical landmark. Since Evelyn George is a member of that society, she undoubtedly favors according landmark status to the city hall as well.
答案选D，我看不出逻辑关系呀

17. On completing both the course in experimental design and the developmental psychology course. Angela will have earned a degree in psychology. Since experimental design, which must be completed before taking developmental psychology, will not be offered until next term, it will be at least two terms before Angela gets her psychology degree.
If the statements above are all true, which one of the following must also be true?
(A) The developmental psychology course Angela needs to take requires two terms to complete
(B) The course in experimental design is an easier course that the course in developmental psychology.
(C) There are no prerequisites for the course in experimental design.
(D) Anyone who earns a degree in psychology form the university Angela attends will have completed the course in experimental design.
(E) Once Angela completes the developmental psychology course, she will have earned a degree in psychology.
答案选E。我觉得不对，题目问前提，可是E说的人家原文本来就说过了On completing both the course in experimental design and the developmental psychology course，Angela will have earned a degree in psychology。On doing sth本来就等于ONCE呀！再说我觉得A对，因为experimental design虽然下学期才开设而且必须在developmental psychology之前学，但是他们可以在一个学期内一先一后学完呀，这样，总共一个学期就可以拿到DEGREE了，除非是其中某一个必须2学期以上才能证明拿到DEGREE至少要2学期。
我说的对不对呢？！

14 的逻辑关系是群体的和个体的特性比较，比如老虎吃人，但不是每个老虎都吃人

17 题目问的可不是前提，题目问的是必要条件。即这个条件不成立，题目中的表述就不真确。A的意思是单单心理发展一门课要两个学期学完，这可不一定吧。E如果不成立，题目中最后一句就不成立。
