When politicians describe their opponent's positions, they typically make those positions seem implausible and unattractive. In contrast, scholars try to make opposing positions seem as plausible and attractive as possible. Doing so makes their arguments against those positions more persuasive to their professional colleagues. politicians should take note: they could persuade more voters with their arguments if they simply followed the scholars in charitably formulating their opponent's positions.

The reasoning in the argument is most vulnerable to criticism on the grounds that...

A. Fails to address the possibility that an approach that works with one kind of audience will not work with another.

B. Fails to account for the difficulty of coming up with charitable formulations of positions to which one is opposed.

C. Focuses on the difference between two styles of argumentation even though those styles might be suited to similar audiences.

D. Takes for granted that both scholars and politicians have persuasion as their aim.

E. Presumes, without giving justification, that politicians formulate the positions of their opponents uncharitably even when they share those positions.

A. Fails to address the possibility that an approach that works with one kind of audience will not work with another.

Laird: Pure research provides us with new technologies that contribute to saving lives. Even more worthwhile than this, however, is its role in expanding our knowledge and providing new, unexplored ideas.

Kim: Your priorities are mistaken. Saving lives is what counts most of all. Without pure research, medicine would not be as advanced as it is.

Laird and Kim disagree on whether pure research

  1. derives its significance in part from its providing new technologies
  2. expands the boundaries of our knowledge of medicine
  3. should have the saving of human lives as an important goal
  4. has its most valuable achievements in medical applications
  5. has any value apart from its role in providing new technologies to save lives

D. has its most valuable achievements in medical applications

Ancient humans in eastern North America hunted mammoths until the mammoth disappeared from the area around 13,000 years ago. Recently, a fossil bone with an engraving that depicts a mammoth was found in an ancient settlement in eastern North America. This shows that the settlement was occupied at a time when mammoths lived in the area.

The argument requires the assumption that:

A. The engraving was made during the time when the settlement was occupied.

B. The fossil on which the engraving was made was not a mammoth bone.

C. When mammoths disappeared from eastern North America, there were no mammoths left anywhere in North America.

D. The engraving technique employed on the fossil was unique to eastern North America.

E. There is no scientific way of dating when the engraving of the mammoth was made.

A. The engraving was made during the time when the settlement was occupied.

Which of the following if true most helps to resolve the apparent discrepancy in the information above?

A. Because no single person is the author of a folktale, folk tales must reflect the values of a culture rather than those of an individual.

B. Folk tales are often oral traditions that persist from times when people left written materials far less frequently.

C. The manner in which a culture adapts its narratives reveals information about the values of that culture.

D. The ancient narratives persist largely because they speak to the basic themes and features of the human condition.

E. Folk tales are often morality tales used to teach children the values important to their culture. 

C. The manner in which a culture adapts its narratives reveals information about the values of that culture.

Journalist: To reconcile the need for profits sufficient to support new drug research with the moral imperative to provide medicines to those who most need them but cannot afford them, some pharmaceutical companies feel justified in selling a drug in rich nations at one price and in poor nations at a much lower price. But this practice is unjustified. A nation with a low average income may still have a substantial middle class better able to pay for new drugs than are many of the poorer citizens of an overall wealthier nation.

Which one of the following principles, if valid, most helps to justify the journalist’s reasoning?

  1. People who are ill deserve more consideration than do healthy people, regardless of their relative socioeconomic positions.
  2. Wealthy institutions have an obligation to expend at least some of their resources to assist those incapable of assisting themselves.
  3. Whether one deserves special consideration depends on one’s needs rather than on characteristics of the society to which one belongs.
  4. The people in wealthy nations should not have better access to health care than do the people in poorer nations.
  5. Unequal access to health care is more unfair than an unequal distribution of wealth.

C. Whether one deserves special consideration depends on one’s needs rather than on characteristics of the society to which one belongs.

From time to time there is a public outcry against predatory pricing- where a company deliberately sells its products at prices low enough to drive its competitors out of business. But this practice clearly should be acceptable, b/c even after its competitors go out of business, the mere threat of renewed competition will prevent the company from raising its prices to unreasonable levels.

Which one of the following is an assumption on which the argument depends?

A. Any company that is successful will inevitably induce competitors to enter the market.

B. It is unlikely that several competing companies will engage in predatory pricing simultaneously.

C. Only the largest and wealthiest companies can engage in predatory pricing for a sustained period of time.

D. It is only competition or the threat of competition that keeps companies from raising prices.

E. Any pricing practice that does not result in unreasonable prices should be acceptable.

Lawyer: If you take something that you have good reason to think is someone else's property, that is stealing, and stealing is wrong. However, Meyers had no good reason to think that the compost in the public garden was anyone else's property, so it was not wrong for Meyers to take it.

The reasoning in the lawyer's argument is flawed in that the argument:

A. Confuses a factual claim with a moral judgment.

B. Takes for granted that Meyers would not have taken the compost if he had good reason to believe that it was someone else's property.

C. Takes a condition that by itself is enough to make an action wrong to also be necessary in order for the action to be wrong.

D. Fails to consider the possibility that the compost was Meyers' property. 

E. Concludes that something is certainly someone else's property when there is merely good, but not conclusive. reason to think that it is someone else's property. 

C. Takes a condition that by itself is enough to make an action wrong to also be necessary in order for the action to be wrong.

The supernova event of 1987 is interesting in that there is still no evidence of the neutron star that current theory says should have remained after a supernova of that size. This is in spite of the fact that many of the most sensitive instruments ever developed have searched for the tell-tale pulse of radiation that neutron stars emit. Thus, current theory is wrong in claiming that supernovas of a certain size always produce neutron stars.

Which one of the following, if true, most strengthens the argument?

  1. Most supernova remnants that astronomers have detected have a neutron star nearby.
  2. Sensitive astronomical instruments have detected neutron stars much farther away than the location of the 1987 supernova.
  3. The supernova of 1987 was the first that scientists were able to observe in progress.
  4. Several important features of the 1987 supernova are correctly predicted by the current theory.
  5. Some neutron stars are known to have come into existence by a cause other than a supernova explosion.

D. Several important features of the 1987 supernova are correctly predicted by the current theory.
