POWERSCORE的变态CR。虐死你们!!! Assumption 1.Barnes: The two newest employees at this company have salaries that aretoo high for the simple tasks normally assigned to new employees and duties that are too complex for inexperienced workers. Hence, the salaries and the complexity of the duties of these two newest employees should be reduced. Which one of the following is an assumption on which Barnes’s argument depends? C. The two newest employees are not experienced at their occupations.
2. The current pattern of human consumption of resources, in which we rely on nonrenewable resources, for example metal ore, must eventually change. Since there is only so much metal ore available, ultimately we must either do without or turn to renewable resources to take its place.
Which one of the following is an assumption required by the argument?
(B) We cannot indefinitely replace exhausted nonrenewable resources with other nonrenewable resources.
4.Publicity campaigns for endangered species are unlikely to have much impact on the most important environmental problems, for while the ease of attributing feelings to large mammals facilitates evoking sympathy for them, it is more difficult to elicit sympathy for other kinds of organisms, such as the soil microorganisms on which large ecosystems and agriculture depend. Which one of the following is an assumption on which the argument depends?
(A) The most important environmental problems involve endangered species other than large mammals.
3. In humans, ingested protein is broken down into amino acids, all of which must compete to enter the brain. Subsequent ingestion of sugars leads to the production of insulin, a hormone that breaks down the sugars and also rids the bloodstream of residual amino acids, except for tryptophan, Tryptophan then slips into the brain uncontested and is transformed into the chemical serotonin, increasing ht brainâ?s serotonin level. Thus sugars can play a major role in mood elevation, helping one to feel relaxed and anxiety-free.
Which one of the following is an assumption on which the argument depends?
(D) Increasing the level of serotonin in the brain promotes relaxation and freedom from anxiety.
5.Historian: Leibniz, the seventeenth-century philosopher, published his version of calculus before Newton did. But then Newton revealed his private notebooks, which showed he had been using these ideas for atleast a decade before Leibniz's publication. Newton also claimed that he had disclosed these ideas to Leibniz in a letter shortly before Leibniz's publication. Yet close examination of the letter shows that Newton's few cryptic remarks did not reveal anything important about calculus. Thus, Leibniz and Newton each indepedently discovered calculus.
WHich one of the following is an assumption required by the historian's argument?
E) Neither Newton nor Leibniz learned crucial details about calculus from some third source. |
