Many athletes inhale pure oxygen after exercise in an attempt to increase muscular reabsorption of oxygen. Measured continuously after exercise, however, the blood lactate levels of athletes who inhale pure oxygen are practically identical, on average, to those of athletes who breathe normal air. The lower the blood lactate level is, the higher the muscular reabsorption of oxygen is.If the statements above are all true, they most strongly support which of the following conclusions?

Infotek, a computer manufacturer in Katrovia, has just introduced a new personal computer model that sells for significantly less than any other model. Market research shows, however, that very few Katrovian households without personal computers would buy a computer, regardless of its price. Therefore, introducing the new model is unlikely to increase the number of computers in Katrovian homes.Which of the following is an assumption on which the argument depends?

Last year a chain of fast-food restaurants, whose menu had always centered on hamburger, added its first vegetarian sandwich, much lower in fat than the chain's other offerings. Despite heavy marketing, the new sandwich accounts for a very small proportion of the chain's sales. The sandwich's sales would have to quadruple to cover the costs associated with including it on the menu. Since such an increase is unlikely, the chain would be more profitable if it dropped the sandwich. Which of the following, if true, most seriously weakens the argument?

The introduction of the new drugs into the market is frequently prevented by a shortage of human subjects for the clinical trials needed to show that the drugs are safe and effective. Since the lives and health of people in future generations may depend on treatments that are currently experimental, practicing physicians are morally in the wrong when, in the absence of any treatment proven to be effective, they fail to encourage suitable patients to volunteer for clinical trials.Which of the following, if true, casts most doubt on the conclusion of the argument?

The recent rise of low-cost airlines in Country Y has led to great increases in the number of air travelers and flights. However, a “hidden cost” of flying and certain other forms of travel is the significant amount of air pollution, which contributes to global warming. To make people pay these hidden costs—and in the process discourage the explosive growth in flying—the government of Country Y plans to impose fees on all air travel. There is a problem, however, in that many residents of Country Y would then use automobile transportation instead, without paying the hidden costs of the resulting air pollution.Which of the following additions to the government's plan would be likely to help most in overcoming the problem referred to in the final sentence above?

Letter to the editor: Our city plans to allow major commercial development along the south waterfront and, in so doing, to increase its tax revenue.But, to succeed commercially, the development would inevitably create far more road traffic than the existing roads to the waterfront can handle, causing serious congestion. Providing enough roads or public transportation to the area would cost far more than the city could gain from the increased tax revenue.Which of the following, if added to the city's plan, would be most likely to help solve the problem the letter describes?
