95. Scientific research that involves international collaboration has produced papers of greater influence, as measured by the number of times a paper is cited in subsequent papers, than has research without any collaboration. Papers that result from international collaboration are cited an average of seven times, whereas papers with single authors are cited only three times on average. This difference shows that research projects conducted by international research teams conducted by single researchers.
Which one of the following is an assumption on which the argument depends?
(A) Prolific writers can inflate the number of citations they receive by citing themselves in subsequent papers.
(B) It is possible to ascertain whether or not a paper is the product of international collaboration by determining the number of citations it has received.
(C) The number of citations a paper receives is a measure of the importance of the research it reports.
(D) The collaborative efforts of scientists who are citizens of the same country do not produce papers that are as important as papers that are produced by international collaboration.
(E) International research teams tend to be more generously funded than are single researchers.
答案是Ｃ．可怜我对highlight的那句话理解不了！不明白啊，想的头都疼了．
Questions 103
The brains of identical twins are genetically identical. When only one of a pair of identical twins is a schizophrenic, certain areas of the affected twin’s brain are smaller than corresponding areas in the brain of the unaffected twin. No such differences are found when neither twin is schizophrenic. Therefore, this discovery provides definitive evidence that schizophrenia is caused by damage to the physical structure of the brain.
If the statements on which the conclusion above is based are all true, each of the following could be true EXCEPT:
(A) People who lack a genetic susceptibility for the disease will not develop schizophrenia
(B) Medications can control most of the symptoms of schizophrenics share many of the characteristics found in those of people without the disorder
(C) The brains of schizophrenics share many of the characteristics found in those of people without the disorder
(D) It will eventually be possible to determine whether or not someone will develop schizophrenia on the basis of genetic information alone
(E) Brain abnormalities associated with schizophrenia are the result of childhood viral infections that inhibit the development of brain cells
我对提干的理解是：
ＩＤＥＮＴＩＣＡＬＴＷＩＮＳ 的大脑在基因上是相同的， 如果ＴＷＩＮ中其中一个有精神分裂症，那么患者脑中局部就比哪个未患精神分裂症ＴＷＩＮ小． 如果任何一个ＴＷＩＮ都没得精神分裂症，这种大小的区别也就不存在． 结论：脑部结构受伤（暗示不是基因的问题）造成精神分裂症；
Ｄ 和结论的暗示相反，说是可以有基因来判断是否得精神分裂症，WRONG, 所以是正确答案．
我的问题是怎么排除Ａ，和Ｂ? 我看不出这两个are "TRUE" based on the known information.
107. Because of the recent transformation of the market, Quore, Inc., must increase the next two years, or it will certainly go bankrupt. In fact, however, Quore’s production structure is such that if a 10 percent productivity increase is possible, then a 20 percent increase is attainable.
If the statements above are true, which one of the following must on the basis of them also be true?
(A) It is only Quore’s production structure that makes it possible for Quore to survive the transformation of the market.
(B) Quore will not go bankrupt if it achieves a productivity increase of 20 percent over the next two years.
(C) If the market had not been transformed, Quore would have required no productivity increase in order to avoid bankruptcy.
(D) Because of the transformation of the market, Quore will achieve a productivity increase of 10 percent over the next two years.
(E) If a 20 percent productivity increase is unattainable for Quore, then it must go bankrupt.
但不明白怎样排除Ｂ，Ｃ．怎么都想不通．试着去apply 一些前面高手的经验和心得，还是不得其法．真是郁闷啊．真的很佩服那些视逻辑题如透明题的牛人们，真是不易达到的境界啊．
