RESULTS OF TWO SURVEYS OF OPINIONS REGARDING THE EFFECTS OF SCIENCE ON HUMAN SOCIETY
A table shows survey responses for August 1991 and August 1992.
- Mostly beneficial: 25% (1991) \(\rightarrow\) 81% (1992)
- Equally harmful and beneficial: 37% (1991) \(\rightarrow\) 9% (1992)
- Mostly harmful: 20% (1991) \(\rightarrow\) 7% (1992)
- No opinion: 18% (1991) \(\rightarrow\) 3% (1992)
Which of the following, if true, contributes most to explaining the shift in opinions about the effects of science on human society?
Drug manufacturer: Although our company requires that patients who use our new drug also purchase from us nonreusable kits for weekly blood testing, the expense of those kits is an entirely necessary one: weekly blood testing must be done to monitor the drug's potential side effects, which can be very dangerous.
Which of the following, if true, most seriously weakens the manufacturer's argument?
Virginia and her brother William disagree over when their father was born: Virginia claims it was in 1935 and William claims it was in 1933. The hospital where their father was born has no records for 1933 but has complete records for 1935--records that do not include a birth record for their father. Therefore, he must have been born in 1933.
The argument depends on which of the following assumptions?
Politician: Each year, small businesses create more jobs than do large established businesses. Therefore, in order to reduce unemployment in the long term, we should provide incentives for starting small businesses rather than for expanding established large businesses.
Which of the following, if true, casts the most doubt on the politician's argument?
In the workplace, influenza is typically spread by infected individuals to others with whom they work in close quarters. A new medication that suppresses the symptoms of influenza therefore will actually increase the number of influenza cases, because this medication will allow people who would otherwise be home in bed to return to work while infected.
Which of the following, if true, most seriously challenges the prediction?
Editorial: Critics of nuclear power complain about the allegedly serious harm that might result from continued operation of existing nuclear power plants. But such concerns do not justify closing these plants; after all, their operation has caused no more harm than that caused by pollution generated by coal-and oil-burning power plants, the most important other sources of energy.
Which of the following is an assumption on which the argument depends?
To improve productivity, manufacturing companies have recently begun restructuring work to produce more goods with fewer assembly-line workers, and the companies have laid off many workers as a consequence. The workers laid off have been those with the least seniority (time on the job), generally the younger workers.
The statements above, if true, most strongly support which of the following as a conclusion?
During the nineteenth century, Britain's urban population increased as its rural population diminished. A historian theorizes that, rather than industrialization's being the cause, this change resulted from a series of migrations to urban areas, each occasioned by a depression in the agrarian economy. To test this hypothesis, the historian will compare economic data with population census data.
The historian's hypothesis would be most strongly supported if which of the following were found to be true?
