60) The following appeared in a letter from a firm providing investment advice for a client.
Most homes in the northeastern United States, where winters are typically cold, have traditionally used oil as their major fuel for heating. Last heating season that region experienced 90 days with below-normal temperatures, and climate forecasters predict that this weather pattern will continue for several more years. Furthermore, many new homes are being built in the region in response to recent population growth. Because of these trends, we predict an increased demand for heating oil and recommend investment in Consolidated Industries, one of whose major business operations is the retail sale of home heating oil.
Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted.
这个argument有一个最终的结论或者claim-
we predict an increased demand for heating oil and recommend investment in Consolidated Industries
由于这是一个并列结构,实际有两个claims
- demand of heating oil will icnrease
- investing in CI will be profitable/desirable
再来看看有什么data或evidence
1) oil is the major fuel for heating (traditionally)
2) Last heating season that region experienced 90 days with below-normal temperatures, and climate forecasters predict that this weather pattern will continue for several more years
3) many new homes are being built in the region in response to recent population growth

145) The following appeared in a memo to the board of directors of a company that specializes in the delivery of heating oil.
Most homes in the northeastern United States, where winters are typically cold, have traditionally used oil as their major fuel for heating. Last heating season, that region experienced 90 days with below-normal temperatures, and climate forecasters predict that this weather pattern will continue for several more years. Furthermore, many new homes are being built in the region in response to recent population growth. Because of these trends, we can safely predict that this region will experience an increased demand for heating oil during the next five years.
Write a response in which you discuss what questions would need to be answered in order to decide whether the prediction and the argument on which it is based are reasonable. Be sure to explain how the answers to these questions would help to evaluate the prediction.
问的是需要问什么问题 其实找假设的答案可以调整一下,变为提出相关的问题
It is assumed that the residents in the region will not switch to alternative energy sources for heating
可改为
The questions we need to ask are: are alternative energy sources available for heating in the region and how expensive are they relateive to oil
而针对146
Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.
We need evidence about the availability of alternative energy sources for heating in the region
唯一需要区别对待的可能是 rival explanation的题型
165) Humans arrived in the Kaliko Islands about 7,000 years ago, and within 3,000 years most of the large mammal species that had lived in the forests of the Kaliko Islands were extinct. Previous archaeological findings have suggested that early humans generally relied on both fishing and hunting for food; since archaeologists have discovered numerous sites in the Kaliko Islands where the bones of fish were discarded, it is likely that the humans also hunted the mammals. Furthermore, researchers have uncovered simple tools, such as stone knives, that could be used for hunting. The only clear explanation is that humans caused the extinction of the various mammal species through excessive hunting.
Write a response in which you discuss one or more alternative explanations that could rival the proposed explanation and explain how your explanation(s) can plausibly account for the facts presented in the argument.
