  Reasoning

  How does the television executive cal the drug manufacturer’s argument into question? The drug manufacturer argues that presenting the image of a physician is harmless because it will not unduly influence television audiences.

  The television executive says that in that case, the advertisement does not need to present that image. The executive's point is that given that the purpose of any advertisement is to influence an audience, the reason the drug manufacturer gives for allowing an advertisement presenting an image of a physician to be broadcast actually conflicts with the motive for presenting such an image. Consider the answer options and find one that explains the executive's argumentative strategy in making this point.

  A. Correct. The manufacturer's presumed motive for presenting the image of a physician is to make the advertisement more persuasive, but the reason the manufacturer offers for relaxing the guidelines is that the image will not be very persuasive. The executive points out this conflict.

  B. The executive may implicitly question the manufacturer's intentions but does not actually say the manufacturer is motivated by self-interest

  C. The executive merely points out an implication of the manufacturer's opinion about audience reactions without evaluating that opini0n's objectivity.

  D. The executive does not say or imply anything about the goals of television networks.

  E. The executive merely points out an implication of the manufacturer's sweeping generalization without evaluating that generalization's plausibility or the manufacturer's ability to make other generalizations.

  The correct answer is A.

  Reasoning

  Given the facts stated, what would make the proposed laws more likely to be affordable for Gandania? Because the argument is intended to establish that Gandania cannot afford to institute laws to curtail tobacco use, and you are

  asked to find the answer choice that would weaken the argument, your should try to determine which answer choice most strongly suggests that it would be affordable for Gandania to institute the laws. The argument implies that the laws might reduce Gandania's profits from tobacco sales while also reducing the incidence of smoking-related health problems. The proposed laws would be more affordable if reducing smoking-related health problems would financially benefit Gandania, compensating for the reduced profits from tobacco sales.

  A. Correct. If the government funds all health care in Gandania, then reducing smoking-related health problems might reduce the government's health care expenses and make the laws to curtail tobacco use more affordable.

  B. If implementing the laws does not increase tobacco exports, then profits from tobacco exports probably would not increase to compensate for the declining profits from reduced domestic tobacco sales.

  C. Although the percentage of revenue from tobacco sales has held steady in recent years, when the laws are implemented, the percentage will decline.

  D. The argument says that profits from tobacco sales account for 10 percent of total annual revenues. Therefore, the other 90 percent must come from all other sources combined, no matter how comes from any individual source.

  E. If no government officials had previously proposed laws to curtail tobacco use, that might be because such laws are clearly unaffordable.

  The correct answer is A.

  Reasoning

  Given the facts the mal owner has stated, what would make it more likely that the mal could increase profits without new tenants? The mall owner says the mall's occupancy rate is low, so there must be many vacancies. The owner rules out the possibility of raising rents and expresses concern about losing established tenants. The owner also points out that running a mall with scattered vacancies costs as much as running a fully occupied mall. Look for an answer choice suggesting how the owner could reduce expenses or make more money while neither changing the number of tenants nor raising rents.

  A. Correct. If expenses can be reduced by consolidating existing tenants and closing a wing of the mall, then neither the number of tenants nor the rents need to change in order to increase profits.

  B. The relative cost of air-conditioning to heating is largely irrelevant to the argument.

  C. Although this suggests that the mall could stay in business without new tenants, it does not suggest a way for the mall to actually increase profits.

  D. This supports the mall owner's concern that raising rents would drive away tenants, but we are looking for evidence to weaken the mall owner's argument, not to support it.

  E. If the established tenants will not need to rent more space, it will not be feasible for the mall to charge them more without raising rents.

  The correct answer is A.
