8、ave died elsewhere. The australopithecines thus must have been mighty hunters, to have brought home so much meat.Which of the following, if true, most seriously weakens the conclusion drawn above?(A) The australopithecines sometimes moved from cave to cave for shelter and did not remain in one cave

9、for a lifetime.(B) The australopithecine bones found in the caves were those of adult males, adult females, and juveniles.(C) Evidence of the use of fire was absent from the caves in which the collections of bones were found.(D) Marks on the bones, including the bones of the australopithecines, are

10、consistent with teeth marks of large catlike animals of the period.(E) The bones in the cave did not include bones of an elephantlike animal that existed in the area at the time of the australopithecines.（分数：5.00）A.B.C.D.E.4.Many researchers believe that the presence of RNA in brain cells is the bio

11、chemical basis of memory; that is, the presence of RNA enables us to remember. Because certain chemicals are known to inhibit the synthesis of RNA in the body, we can test this hypothesis. Animals that have learned particular responses can be injected with an RNA inhibitor and then tested for memory

12、 of the learned responses. Which of the following test results would most seriously weaken the case for RNA as the basis of memory?(A) After an injection of RNA inhibitor, a wide range of behaviors in addition to the learned responses were affected.(B) After an injection of RNA inhibitor, animals th

13、at had not consistently been giving the learned responses were able to give them consistently.(C) After injections of RNA inhibitor, some animals lost memory of the learned responses totally but others lost it only partially.(D) After a small injection of RNA inhibitor, animals responded well, but a

14、s the size of the injection increased, they gave fewer of the learned responses.(E) After an injection of RNA inhibitor, animals could not learn a new response.（分数：5.00）A.B.C.D.E.5.When college students were asked about their experiences in childhood, those who remembered their parents frequently be

15、ing in pain were also those who experienced common pains, like headaches, most frequently as adults. This evidence argues that a persons childhood observations of adults in pain can make that person more susceptible to pain as an adult.Which of the following, if true, most seriously weakens the argu

16、ment above?(A) Students who most frequently remembered that they were in pain as children were no more likely than the average student to experience common pains very frequently.(B) Parents who were frequently in pain when their children were growing up often experience just as much pain after their

17、 children have grown up.(C) College students are in general less susceptible to common pains, like headaches, than are older adults.(D) Adult memories of the circumstances of childhood pain are often vivid, but adults can rarely recall the subjective experience of being in pain as a child.(E) A pers

21、w burner.(C) Very poor efficiency in the Clifton Asphalt plants old burner.(D) A decrease in the demand for asphalt.(E) A steady increase in the price of oil beginning soon after the new burner is installed.（分数：5.00）A.B.C.D.E.7.Middletowns police currently remove an apparently abandoned car from the

30、xactly how thorough they should be. Therefore, it is generally unwise for patients to have medical checkups when they do not feel ill.Which one of the following, if true, would most seriously weaken the argument in the passage?(A) Some serious diseases in their early stages have symptoms that physic

33、g sets of identical twins who were raised apart in dissimilar environments found that in each case the twins were similar in character, medical history, and life experiences.

37、ited States during their vulnerable childhood years is primarily responsible for this trend.Which of the following, if true, most seriously weakens the explanation above?(A) Seventy-five percent of the people in the United States who are 85 or older are the children of people who themselves lived le

38、as than 65 years.(B) The people in the United States who are now 85 represent an age group that was smaller in numbers at birth than the immediately preceding and succeeding age groups.(C) Thirty-five percent of the people in the United States who are 85 or older require some form of twenty-fourhour

40、to decrease.（分数：5.00）A.B.C.D.E.12.Behind the hope that computers can replace teachers is the idea that the students understanding of the subject being taught consists in knowing facts and rules, the job of a teacher being to make the facts and rules explicit and convey them to the student, either by

41、 practice drills or by coaching. If that were indeed the way the mind works, the teacher could transfer facts and roles to the computer, which would replace the teacher as drillmaster and coach. But since understanding does not consist merely of knowing facts and rules, but of the grasp of the gener

42、al concepts underlying them, the hope that the computer will eventually replace the teacher is fundamentally misguided.Which one of the following, if true, would most seriously undermine the authors conclusion that computers will not eventually be able to replace teachers?(A) Computers are as good a

43、s teachers at drilling students on facts and rules.(B) The job of a teacher is to make students understand the general concepts underlying specific facts and rules.(C) It is possible to program computers so that they can teach the understanding of general concepts that underlie specific facts and ru

44、les.(D) Because they are not subject to human error, computers are better than teachers at conveying facts and rules.(E) It is not possible for students to develop an understanding of the concepts underlying facts and rules through practice drills and coaching.（分数：5.00）A.B.C.D.E.13.A certain type of

45、 shrimp habitually hovers around superheated deep-sea geysers, near which the bacteria that form the shrimps diet can be found.

46、.Which of the following, if true, casts the most doubt on the scientists conclusion?(A) The light to which the shrimps are sensitive is not the sort of light that the geysers emit.(B) The light given off by the geysers too faint to be detected by the human eye.(C) The heat inside a geysers stream is

47、 sufficient to kill instantly any bacteria that move into it.(D) Most other types of shrimp use eyes located at the end of eyestalks in order to see.(E) In other types of shrimp a heat-sensing organ has developed that could serve the same geyser-detecting purposes as the light sensitive patches are

48、said to serve.（分数：5.00）A.B.C.D.E.14.Seven countries signed a treaty binding each of them to perform specified actions on a certain fixed date, with the actions of each conditional on simultaneous action taken by the other countries.
