这是第二篇A, 第一篇写的 “千疮百孔”, 这篇感觉好一点, 麻烦给指点。 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.
In this argument, the author draws a conclusion that increasing investment in Cnosolidated Industries to satisfied the demand of home heating oil based on several evidences. It seems convincing at the first glance. However, those evidences the author commits several faws in this argument.
To bolster this conclusion, the author points out that: last heating season that region experienced 90 days with below normal temperatures, and climate forecasters predict that this weather pattern will continue for several or more years. Actually, the author means that the region's climate will very cold year by year, so that the heating oil will be used more that before. But there are several unfounded assumptions in this evidence. Firstly, the author assume that the time of low temperature is long. Nevertheless, if this just is a common phenomenonthar the region experienced 90 days with below normal temperatures in last several years. the author's conclusion is vague. And as far as we now, since today on one technology can definitely forecast the weather in the future. Therefore, we cannot get the this conclusion form above reasons, so that the demand of home heating oil dose not increase. To strengthen the arguer deduction, more information should be given. For example, how the climate in the last several years. And how the forecasterprediction definition .
Secondly, the arguer says: many new homes are being built in the region in response to recent population growth. It dose not enough evidences to contribute it. Firstly, the recent population growth is vague, there not enough formation about population increasing tendency in the region. If the arguer infers the population growth by the recent years tendency, it is does not convincing. Perhaps there are other factors lead to people reduce their spending, such as economic crisis, so that few people will come here. Secondly, the author's deduction is unfounded.Even if the population in this region will growth, we cannot say the new homes are being built in the region. Perhaps people just live here for several days, they are not intend to buy new homes but rent here departments; or there people do not prepare to live here in winter because of the cold climate. Thirdly, there is a few in author's conclusion. Even if there an increasing number of people will buy this home, we can not say they will regard the heating oil as a main fuel for heating. Maybe they will create heating by other fuels that are clear fuel and more economic. Based these possibles, we can get this conclusion that many new homes will being built in this region and the demand for heating oil does not increase. To make the conclusion more convincing, more information should be collected, for example, whether the population will increase or not; whether the people will buy this home or not; whether the people who has brought here home will use the oil as a main fuel.
To sum up, this argument is unconvincing based above analysis. Hence, the author should provide more information about his or her evidences.
