问答题The following appeared in a memorandum written by the vice president of Nature’s Way, a chain of stores selling health food and other health-related products. “Previous experience has shown that our stores are most profitable in areas where residents are highy concerned with leading healthy lives. We should therefore build our next new store in Plalnsville, which has many such residents. Plainsiville merchants report that sales of running shoes and exercise dothiog are at all-time highs. The local health club, which nearly closed five years ago due to lack of business, has more members than ever, and the weight training and aerobics classes are always full. We can even anticipate a new generation of customers: Plainsiville’s schoolchildren are required to participate in a ‘fitness for life’ program, which emphasizes the benefits of regular exercise at an early age.” Discuss how well-reasoned you find this argument.

You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it more logically sound, and what, if anything, would help you better evaluate its conclusion.

问答题The following is a transcript of a statement made by a recording industry executive at an industry conference: “The music recording industry is suffering grave economic losses due to the widespread piracy of digital music. This fate was an inevitable result of the industry’s misguided decision to switch from the analogue format of vinyl records to the digital formats used today on compact disks and computer files. Copying a vinyl record requires expensive and bulky machinery, whereas anyone with a computer and an Internet connection can start up a music piracy business. To boost music revenues, the recording industry should switch entirely back to the analogue format of vinyl records. Also, I can state with complete authority that music just sounds better on a vinyl record.” Discuss how well-reasoned you find this argument. In your discussion, be sure to analyze the line of reasoning and the use of evidence in the argument. For example, you may need to consider what questionable assumptions underlie the thinking and what alternative examples or counterexamples might weaken the conclusion.

Which of the following is an assumption on which the argument depends?AThere are fossilized nondeciduous trees from Antarctica that bear frost rings.BDeciduous trees are more likely to bear frost rings than are other tree varieties.CThe process of fossilization does not completely obscure frost rings in deciduous trees.DPresent-day deciduous trees are more sensitive to changes in temperature than were the deciduous trees of ancient Antarctica.EProlonged and unseasonable frosts that might have occurred in Antarctica when the now-fossilized trees were still living did not always produce frost rings in deciduous trees.
