15. Susan: Those who oppose experimentation on animals do not properly value the preservation of human life. Although animal suffering is unfortunate, it is justifiable if it can lead to cures for human ailments. Melvin: But much animal experimentation involves testing of ordinary consumer products such as soaps, dyes, and cosmetics. Susan: These experiments are justifiable on the same grounds, since cleanliness, convenience, and beauty are worthwhile human values deserving of support. Which of the following is the best statement of the logical flaw in Susan’s argument? (A) Her claim that animal experimentation is justifiable if it supports human values contradicts her claim that such experimentation is justifiable only if it leads to cures for human ailments. (B) She places a higher value on human cleanliness, convenience, and beauty than she does on the preservation of animal life. © She uses the word “value” in two different senses. (D) She assumes that all ordinary consumer products aid in the preservation of human life. (E) She fails to show how mere support for human values actually preserves human lives.

Questions 5-6 are based on the following. Although its purpose is laudable, the exclusionary rule, which forbids a court to consider evidence seized in violation of the defendant’s constitutional rights, has unduly hampered law-enforcement efforts. Even when the rights violation was a minor or purely technical one, turning on a detail of procedure rather than on the abrogation of some fundamental liberty, and even when it has been clear that the police officers were acting in good faith, the evidence obtained has been considered tainted under this rule and may not even by introduced. In consequence, defendants who were undoubtedly guilty have been set free, perhaps to steal, rape, or murder again. 5. The author of the passage above assumes all of the following EXCEPT: (A) The constitutional rights of criminal defendants should be protected. (B) Most cases in which the exclusionary rule has been invoked have involved purely technical violations of constitutional principles. © The number of cases whose outcome has been affected by the exclusionary rule is significant. (D) Some of the defendants set free under the exclusionary rule have been guilty of serious criminal offenses. (E) Merely technical violations of the rules concerning evidence should be treated differently from deliberate assaults upon human rights. 6. It can be inferred from the passage that the author would most likely endorse which of the following proposals? (A) Change of the exclusionary rule to admit evidence obtained by police officers acting in good faith (B) A constitutional amendment curtailing some of the protections traditionally afforded those accused of a crime © A statute limiting the application of the exclusionary rule to cases involving minor criminal offenses (D) Change of the exclusionary rule to allow any evidence, no matter how obtained, to be introduced in court (E) A constitutional amendment allowing police officers to obtain vital evidence by any means necessary when in pursuit of a known criminal

3. To avoid a hostile takeover attempt, the board of directors of Wellco, Inc., a provider of life and health insurance, planned to take out large loans and use them to purchase a publishing company, a chocolate factory, and a nationwide chain of movie theaters. The directors anticipated that these purchase initially would plunge the corporation deep into debt, rendering it unattractive to those who wanted to take it over, but that steadily rising insurance rates would allow the company to pay off the debt within five years. Meanwhile, revenues from the three new businesses would enable the corporation as a whole to continue to meet its increased operating expenses. Ultimately, according o the directors’ plan, the diversification would strengthen the corporation by varying the sources and schedules of its annual revenues. Which of the following, assuming that all are equally possible, would most enhance the chances of the plan’s success? (A) A widespread drought decreases the availability of cacao beans, from which chocolate is manufacture, diving up chocolate prices worldwide. (B) New government regulations require a 30 percent across-the-board rate rollback of all insurance companies, to begin immediately and to be completed within a five-year period. © Congress enacts a statute, effective after six months, making it illegal for any parent not to carry health insurance coverage for his or her child. (D) Large-screen televisions drop dramatically in price due to surprise alterations in trade barriers with Japan; movie theater attendance dwindles as a consequence. (E) A new, inexpensive process is discovered for making paper pulp, and paper prices fall to 60 percent of their former level.

1. Contrary to the statements of labor leaders, the central economic problem facing America today is not the distribution of wealth. It is productivity. With the productivity of U.S. industry stagnant, or even declining slightly, the economic pie is no longer growing. Labor leaders, of course, point to what they consider an unfair distribution of the slices of pie to justify their demands for further increases in wages and benefits. And in the past, when the pie was still growing, management could afford to acquiesce. No longer. Until productivity resumes its growth, there can be no justification for further increases in the compensation of workers. Which of the following statements by a labor leader focuses on the logical weakness in the argument above? (A) Although the economic pie is no longer growing, the portion of the pie allocated to American workers remains unjustly small. (B) If management fails to accommodate the demands of workers, labor leaders will be forced to call strikes that will cripple the operation of industry. © Although productivity is stagnant, the U.S. population is growing, so that the absolute size of the economic pie continues to grow as well. (D) As a labor leader, I can be concerned only with the needs of working people, not with the problems faced by management. (E) The stagnation of U.S. industry has been caused largely by factors—such as foreign competition—beyond the control of American workers.

20. Which of the following best completes the passage below? In today’s pluralistic society, textbook publishers find themselves in an increasingly uncomfortable position. Since the schools are regarded as a repository of society’s moral and cultural values, each group within society wishes to prevent any material that offends its own values from appearing in textbooks. As a result, stance on an issue is certain to run afoul of one group or another. And since textbook publishers must rely on community goodwill to sell their books, it is inevitable that______ (A) fewer and fewer publishers will be willing to enter the financially uncertain textbook industry (B) the ethical and moral content of textbooks will become increasingly neutral and bland © more and more pressure groups will arise that seek to influence the content of textbooks (D) the government will be forced to intervene in the increasingly rancorous debate over the content of textbooks (E) school boards, teachers, and principals will find it nearly impossible to choose among the variety of textbooks being offered please explain:(

16. In 1986, the city of Los Diablos had 20 days on which air pollution reached unhealthful amounts and a smog alert was put into effect. In early 1987, new air pollution control measures were enacted, but the city had smog alerts on 31 days that year and on 39 days the following year. In 1989, however, the number of smog alerts in Los Diablos dropped to sixteen. The main air pollutants in Los Diablos are ozone and carbon monoxide, and since 1986 the levels of both have been monitored by gas spectrography. Which of the following statements, assuming that each is true, would be LEAST helpful in explaining the air pollution levels in Los Diablos between 1986 and 1989? (A) The 1987 air pollution control measures enacted in Los Diablos were put into effect in November of 1988. (B) In December of 1988 a new and far more accurate gas spectrometer was invented. © In February of 1989, the Pollution Control Board of Los Diablos revised the scale used to determine the amount of air pollution considered unhealthful. (D) In 1988 the mayor of Los Diablos was found to have accepted large campaign donations from local industries and to have exempted those same industries from air pollution control measures. (E) Excess ozone and carbon monoxide require a minimum of two years to break down naturally in the atmosphere above a given area.

14. Dr. A: The new influenza vaccine is useless at best and possibly dangerous. I would never use it on a patient. Dr. B: But three studies published in the Journal of Medical Associates have rated that vaccine as unusually effective. Dr. A: The studies must have been faulty because the vaccine is worthless. In which of the following is the reasoning most similar to that of Dr. A? (A) Three of my patients have been harmed by that vaccine during the past three weeks, so the vaccine is unsafe. (B) Jerrold Jersey recommends this milk, and I don’t trust Jerrold Jersey, so I won’t buy this milk. © Wingzz tennis balls perform best because they are far more effective than any other tennis balls. (D) I’m buying Vim Vitamins. Doctors recommend them more often than they recommend any other vitamins, so Vim Vitamins must be good. (E) Since University of Muldoon graduates score about 20 percent higher than average on the GMAT, Sheila Lee, a University of Muldoon graduate, will score about 20 percent higher than average when she takes the GMAT.
