Among the results was this: more of those who had taken anti-seasickness medication before their trip reported symptoms of seasickness than thos
6、e who had not taken such medication. It is clear, then, that despite claims by drug companies that clinical tests show the contrary, people would be better off not taking anti-seasickness medications.Which one of the following, if true, would most weaken the conclusion above?(A) Given rough enough w
7、eather, most ferry passengers will have some symptoms of seasickness.(B) The clinical tests reported by the drug companies were conducted by the drug companies staffs.(C) People who do not take anti-seasickness medication are just as likely to respond to a survey on seasickness as people who do.(D)
8、The seasickness symptoms of the people who took anti-seasickness medication would have been more severe had they not taken the medication.(E) People who have spent money on anti-seasickness medication are less likely to admit symptoms of seasickness than those who have not.88. Court records from med
9、ieval France show that in the years 1300 to 1400 the number of people arrested in the French realm for violent interpersonal crimes (not committed in wars) increased by 30 percent over the number of people arrested for such crimes in the years 1200 to 1300. If the increase was not the result of fals
10、e arrests, therefore, medieval France had a higher level of documented interpersonal violence in the years 1300 to 1400 than in the years 1200 to 1300.Which one of the following statements, if true, most seriously weakens the argument?(A) In the years 1300 to 1400 the French governments category of
11、violent crimes included an increasing variety of interpersonal crimes that are actually nonviolent.(B) Historical accounts by monastic chroniclers in the years 1300 to 1400 are filled with deions of violent attacks committed by people living in the French realm.(C) The number of individual agreement
12、s between two people in which they swore oaths not to attack each other increased substantially after 1300.(D) When English armies tried to conquer parts of France in the mid-to late 1300s, violence in the northern province of Normandy and the southwestern province of Gascony increased.(E) The popul
13、ation of medieval France increased substantially during the first five decades of the 1300s, until the deadly bubonic plague decimated the population of France after 1348.89. Rhizobium bacteria living in the roots of bean plants or other legumes produce fixed nitrogen, which is one of the essential
14、plant nutrients and which for non-legume crops, such as wheat, normally must be supplied by applications of nitrogen-based fertilizer. So if biotechnology succeeds in producing wheat strains whose roots will play host to Rhizobium bacteria, the need for artificial fertilizers will be reduced.The arg
15、ument above makes which one of the following assumptions?(A) Biotechnology should be directed toward producing plants that do not require artificial fertilize.(B) Fixed nitrogen is currently the only soil nutrient that must be supplied by artificial fertilizer for growing wheat crops.(C) There are n
16、o naturally occurring strains of wheat or other grasses that have Rhizobium bacteria living in their roots.(D) Legumes are currently the only corps that produce their own supply of fixed nitrogen.(E) Rhizobium bacteria living in the roots of wheat would produce fixed nitrogen.90. Current legislation
17、 that requires designated sections for smokers and nonsmokers on the premises of privately owned businesses is an intrusion into the private sector that cannot be justified. The fact that studies indicate that nonsmokers might be harmed by inhaling the smoke from others cigarettes is not the main is
18、sue. Rather, the main issue concerns the governments violation of the right of private businesses to determine their own policies and rules.Which of the following is a principle that, if accepted, could enable the conclusion to be properly drawn?(A) Government intrusion into the policies and rules o
19、f private businesses is justified only when individuals might be harmed.(B) The right of individuals to breathe safe air supersedes the right of businesses to be free from government intrusion.(C) The right of businesses to self-determination overrides whatever right or duty the government may have
20、to protect the individual.(D) It is the duty of private businesses to protect employees from harm in the workplace.(E) Where the rights of businesses and the duty of government conflict, the main issue is finding a successful compromise.Gmat考试逻辑试题90题(11)80. Advertisement: Clark brand-name parts are
21、made for cars manufactured in this country. They satisfy all of our government automotive tests-the toughest such tests in the world. With foreign-made parts, you never know which might be reliable and which are cheap look-alikes that are poorly constructed and liable to cost you hundreds of dollars
22、 in repairs. Therefore, be smart and insist on brand-name parts by Clark for your car.The argument requires the assumption that(A) Clark parts are available only in this country(B) foreign-made arts are not suitable for cars manufactured in this country(C) no foreign-made parts satisfy our governmen
23、t standards(D) parts that satisfy or government standards are not as poorly constructed as cheap foreign made parts(E) if parts are made for cars manufactured in our country, they are not poorly constructed81. Nuclear fusion is a process whereby the nuclei of atoms are joined, or fused, and in which
24、 energy is released. One of the by-products of fusion is helium-4 gas. A recent fusion experiment was conducted using heavy water contained in a sealed flask. The flask was, in turn, contained in an air-filled chamber designed to eliminate extraneous vibration. After the experiment, a measurable amo
25、unt of helium-4 gas was found in the air of the chamber. The experiments cited this evidence in support of their conclusion that fusion had been achieved.Which one of the following, if true, would cast doubt on the experimenters conclusion?(A) Helium-4 was not the only gas founding the experiment ch
26、amber.(B) When fusion is achieved, it normally produces several by-products, including tritium and gamma rays.(C) The amount of helium-4 found in the chambers air did not exceed the amount of helium-4 that is found in ordinary air.(D) Helium-4 gas rapidly breaks down, FORMing ordinary helium gas aft
27、er a few hours.(E) Nuclear fusion reactions are characterized by the release of large amount of heat.82. Every photograph, because it involves the light rays that something emits hitting film, must in some obvious sense be true. But because it could always have been made to show things differently t
28、han it does, it cannot express the whole truth and, in that sense, is false. Therefore, nothing can ever be definitively proved with a photograph.(A) Helium-4 was not the only gas found in the experiment chamber.Questions 83-84Some cleaning fluids, synthetic carpets, wall paneling, and other products release toxins, suc
