1. Telephone companies are promoting “voice mail” as an alternative to the answering machine. By recording messages from callers when a subscriber does not have access to his or her telephone, voice mail provides a service similar to that of an answering machine. The companies promoting this service argue that it will soon make answering machines obsolete, since it is much more convenient, more flexible, and less expensive than an answering machine.
Which one of the following, if true, most calls into question the argument made by the companies promoting voice mail?
--FEIFEI54
Key: Answering machines enable the customer to hear who is calling before the customer decides whether to answer the telephone, a service voice mail does not provide.
2. For next year, the Chef’s Union has requested a 10 percent salary increase for each of its members, whereas the Hotel Managers’ Union has requested only an 8 percent salary increase for each of its members. These facts demonstrate that the average dollar amount of the raises that the Chefs’ Union has requested for next year is greater than that of the raises requested by the Hotel Managers’ Union.
Which one of the following, if true, most strengthens the argument?
--FEIFEI42
Key: The current salaries of the members of the Chefs’ Union are, on average, higher than the current salaries of the members of the Hotel Managers’ Union.
3.Historian: We can learn about the medical history of individuals through chemical analysis of their hair. It is likely, for example, that Isaac Newton’s psychological problems were due to mercury poisoning; traces of mercury were found in his hair. Analysis is now being done on a lock of Beethoven’s hair. Although no convincing argument has shown that Beethoven ever had a venereal disease, some people hypothesize that venereal disease caused his deafness. Since mercury was commonly ingested in Beethoven’s time to treat venereal disease, if researchers find a trace of mercury in his hair, we can conclude that this hypothesis is correct.
Which one of the following is an assumption on which the historian’s argument depends?
--FEIFEI21
Key: Some people in Beethoven’s time did not ingest mercury.
4.When investigators discovered that the director of a local charity had repeatedly overstated the number of people his charity had helped, the director accepted responsibility for the deception. However, the investigators claims that journalists were as much to blame as the director was for inflating the charity’s reputation, since they had naively accepted what the director told them, and simply reported as fact the numbers he gave them.
Which one of the following principles, if valid, most helps to justify the investigators’ claim
--FEIFEI53
Key: Anyone who presents as factual a story that turns out to be untrue without first attempting to verify that story is no less responsible for the consequences of that story than anyone else is.
5. The following appeared in a memorandum from the president of a company that makes shampoo:
“A widely publicized study claims that HR2, a chemical compound in our shampoo, can contribute to hair loss after
prolonged use. This study, however, involved only 500 subjects. Furthermore, we have received no complaints from
our customers during the past year, and some of our competitors actually use more HR2 per bottle of shampoo than
we do. Therefore, we do not need to consider replacing the HR2 in our shampoo with a more expensive alternative.”
Discuss how well reasoned . . . etc.
