5.Statement of a US copper mining company: Import quotas should be imposed on the less expensive copper mined outside the country to maintain price of copper in this country; otherwise, our companies will not be able to stay in business.
Response of a US copper wire manufacturer: US wire and cable manufacturers purchase about 70 percent of the copper mined in the US. If the copper prices we pay are not at the international level, our sales will drop, and then the demand for US copper will go down.
If the factual information presented by both companies is accurate, the best assessment of the logical relationship between the two arguments is that the wire manufacturer’s argument.
(A)is self-serving and irrelevant to the proposal of the mining company
(B)is circular, presupposing what it seeks to prove about the proposal of the mining company
(C)shows that the proposal of the mining company would have a negative effect on the mining company’s own business
(D)fails to give reason why the proposal if the mining company should not be put into effect to alleviate the concern of the mining company for staying in business
(E)establishes that even the mining company’s business will prosper if the mining company’s proposal is rejected
A:C)
5. Mr. Primm: If hospitals were private enterprises dependent on profits for their survival, there would be no teaching hospitals, because of the intrinsically high cost of running such hospitals
.
Ms. Nakai: I disagree. The medical challenges provided by teaching hospitals attract the very best physicians. This, in turn, enables those hospitals to concentrate on nonroutine cases.
Which of the following, if true, would most strengthen Ms. Nakai’s attempt to refute Mr. Primm’s claim?
(A)Doctors at teaching hospitals command high salaries
(B)Sophisticated nonroutine medical care commands a high price.
(C)Existing teaching hospitals derive some revenue from public subsidies
(D)The patient mortality rate at teaching hospitals is high.
(E)The modern trend among physicians is to become highly specialized
A:B)
6.A recent survey of all auto accident victims in Dole County found that, of the severely injured drivers and front-seat passengers, 80 percent were not wearing seat belts at the time of their accidents. This indicates that, by wearing seat belts, drivers and front-seat can greatly reduce their risk of being severely injured if they are in an auto accident.
The conclusion above is not properly drawn unless which of the following is true?
(A)Of all the drivers and front-seat passengers in the survey, more than 20 percent were wearing seat belts at the time of their accidents
(B)Considerably more than 20 percent of drivers and front-seat passengers in Dole County always wear seat belts when traveling by car.
(C)More drivers and front seat passengers in the survey than rear-seat passengers were very severely injured belts
(D)More than half of the drivers and front-seat passengers in the survey were not wearing seat time of their accidents
(E)Most of the auto accidents reported to police in Dole County do not involve any serious injury.
A:A)
6. Teenagers are often priced out of the labor market by the government-mandated minimum-wage level because employers cannot afford to pay that much for extra help. Therefore, if Congress institutes a subminimum wage, a new lower legal wage for teenagers, the teenage unemployment rate, which has been rising since 1960, will no longer increase.
Which of the following, if true, would most weaken the argument above?
(A)Since 1960 the teenage unemployment rate has risen when the minimum wage has risen
(B)Since 1960 the teenage unemployment rate has risen even when the minimum wage remained constant
(C)Employers often hire extra help during holiday and warm weather seasons.
(D)The teenage unemployment rate rose more quickly in the 1970’s than it did in the 1960’s
(E)The teenage unemployment rate has occasionally declined in the years since 1960
A:B)
7. This year the New Hampshire Division of Company X set a new a record for annual sales by that division. This record is especially surprising since the New Hampshire Division has the smallest potential market and the lowest sales or any of Company X’s divisions.
Which of the following identifies a flaw in the logical coherence of the statement above?
(A)If overall sales for Company X were sharply reduced, the New Hampshire Division’s new sales record is irrelevant to the company’s prosperity.
(B)Since the division is competing against its own record, the comparison of its sales record with that of other divisions is irrelevant
(C)If this is the first year that the New Hampshire Division has been last in sales among Company X’s divisions, the new record is not surprising at all.
(D)If overall sales for Company X were greater than usual, it is not surprising that the New Hampshire Division was last in sales.
(E)Since the New Hampshire Division has the smallest potential market, it is not surprising that it had the lowest sales.
A:B)
