16. The current proposal to give college students a broader choice in planning their own courses of study should be abandoned. The students who are supporting the proposal will never be satisfied, no matter what requirements are established. Some of these students have reached their third year without declaring a major. One first-year student has failed to complete four required courses. Several others have indicated a serious indifference to grades and intellectual achievement.
A flaw in the argument is that it does which one of the following?
(A) avoids the issue by focusing on supporters of the proposal
(B) argues circularly by assuming the conclusion is true in stating the premises
(C) fails to define the critical term “satisfied”
(D) distorts the proposal advocated by opponents
(E) users the term “student” equivocally
Questions 17-18
The question whether intelligent life exists elsewhere in the universe is certainly imprecise, because we are not sure how different from us something might be and still count as “intelligent life.” Yet we cannot just decide to define “intelligent life” in some more precise way since it is likely that we will find and recognize intelligent life elsewhere in the universe only if we leave our definitions open to new, unimagined possibilities.
17. The argument can most reasonably be interpreted as an objection to which one of the following claims?
(A) The question whether intelligent life exists elsewhere in the universe is one that will never be correctly answered.
(B) Whether or not there is intelligent life elsewhere in the universe, our understanding of intelligent life is limited.
(C) The question about the existence of intelligent life elsewhere in the universe must be made more precise if we hope to answer it correctly.
(D) The question whether there is intelligent life elsewhere in the universe is so imprecise as to be meaningless.
(E) The question whether there is intelligent life elsewhere in the universe is one we should not spend our time trying to answer.
18. The passage, if seen as an objection to an antecedent claim, challenges that claim by:
(A) showing the claim to be irrelevant to the issue at hand
(B) citing examples that fail to fit proposed definition of “intelligent life”
(C) claiming that “intelligent life” cannot be adequately defined
(D) arguing that the claim, if acted on, would be counterproductive
(E) maintaining that the claim is not supported by the available evidence
19. The efficiency of microwave ovens in destroying the harmful bacteria frequently found in common foods is diminished by the presence of salt in the food being cooked. When heated in a microwave oven, the interior of unsalted food reaches temperatures high enough to kill bacteria that cause food poisoning, but the interior of salted food does not. Scientists theorize that salt effectively blocks the microwaves from heating the interior.
Which one of the following conclusions is most supported by the information above?
(A) The kinds of bacteria that cause food poisoning are more likely to be found on the exterior of food than in the interior of food.
(B) The incidence of serious food poisoning would be significantly reduced if microwave ovens were not used by consumers to cook or reheat food.
(C) The addition of salt to food that has been cooked or reheated in a microwave oven can increase the danger of food poisoning.
(D) The danger of food poisoning can be lessened if salt is not used to prepare foods that are to be cooked in a microwave oven.
(E) Salt is the primary cause of food poisoning resulting from food that is heated in microwave ovens.
20. Pamela: Business has an interest in enabling employees to care for children, because those children will be the customers, employees, and managers of the future. Therefore, businesses should adopt policies, such as day-care benefits that facilitate parenting.
Lee: No individual company, though, will be patronized, staffed, and managed only by its own employees’ children, so it would not be to a company’s advantage to provide such benefits to employees’ children, so it would not be to a company’s advantage to provide such benefits to employees when other companies do not.
In which one of the following pairs consisting of argument and objection does the objection function most similarly to the way Lee’s objection functions in relation to Pamela’s argument?
(A) New roads will not serve to relieve this area’s traffic congestion, because new roads would encourage new construction and generate additional traffic.
Objection: Failure to build new roads would mean that traffic congestion would strangle the area even earlier.
(B) Humanity needs clean air to breathe, so each person should make an effort avoid polluting the air.
Objection: The air one person breathes is affected mainly by pollution caused by others, so it makes no sense to act alone to curb air pollution.
(C) Advertised discounts on products draw customers’ attention to the products， so advertised discounts benefit sales.
Objection: Customers already planning to purchase a product accelerate buying to take advantage of advertised discounts, and those subsequent sales suffer.
(D) If people always told lies, then no one would know what the truth was, so people should always tell the truth.
Objection: If people always told lies, then everyone would know that the truth was the opposite of what was said.
(E) Human social institutions have always changed. So even if we do not know what those changes will be, we do know that the social institutions of the future will differ from those of the past.
Objection: The existence of change in the past does not ensure that there will always be change in the future.
