9月1日至9月6日同主题写作 https://bbs.gter.net/thread-2116101-1-1.html
115) The following appeared in a memo from a vice president of a large, highly diversified company.
Ten years ago our company had two new office buildings constructed as regional headquarters for two different regions. The buildings were erected by two different construction companies Alpha and Zeta. Even though the two buildings had identical floor plans, the building constructed by Zeta cost 30 percent more to build, and its expenses for maintenance last year were twice those of the building constructed by Alpha. Furthermore, the energy consumption of the Zeta building has been higher than that of the Alpha building every year since its construction. Such data, plus the fact that Alpha has a stable workforce with little employee turnover, indicate that we should use Alpha rather than Zeta for our contemplated new building project.
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.
提纲:
Claim: Zeta charges more than the building really cost and their building is in poor quality.
Data: A comparison of construction and maintenance costs of two buildings.
Warrant: The building constructed by Zeta cost 30 percent more to build, and its expenses for maintenance last year were twice those of the building constructed by Alpha.
Assumption: The building materials prices in two regions are the same. (If Zeta spend more money on materials, the total budget is higher.)
These two buildings suffer the same weather circumstances in two region. (If the region where Zeta built the building suffer much more rainfall a year, the maintenance should be higher because they have to repair roof more frequently)
Claim: Zeta’s building cost more energy than Alpha’s
Data: Energy consumption comparison between buildings constructed by Alpha and Zeta.
Warrant: the energy consumption of the Zeta building has been higher than that of the Alpha building every year since its construction.
Assumption: Climate in two regions are the same.
Claim: Alpha has a stable workforce
Data: Not given
Warrant: Little employee turnover in Alpha
Assumption: The employee who didn’t leave Alpha are work well and provide enough workforce.
全文:
In the memo, the writer recommend that they should hire Alpha rather than Zeta for their new building project claiming that Alpha is a better contractor for it performed better in their last cooperation. The writer suggest that Alpha provided a better quality building with less budget and its workforce is more stable. While the reasoning of this argument is unconvincing if those assumptions about building budgets, energy costs and companies’ workforce proved to be unwarranted. And the writer’s recommendation will be seriously challenged.
First of all, the author claim that Zeta charged more but provide poor quality contracture. When Alpha and Zeta are asked to build the same layout buildings in two regions, Zeta spend more and Alpha do and its maintenance fee is even higher. Such recommendation relies heavily on the assumption that the building materials prices are the same in two regions. Based on such an assumption, the author conclude Zeta is less reliable in business and shouldn’t be chosen as contractor for their new project. However, Zeta and Alpha built buildings in two regions there is a possibility that it is the prices in materials cause the budget difference. In addition. We are not informed about the weather in these places ,which apparently could be factor of prolonging construction schedule and further maintenance. For instance if more rains happened in the place where Zeta built the building, construction process could be slowed down and they have to repair the roof more often. In that case, the author’s reasoning will be weaken.
Furthermore, by stating that the energy consumption of Zeta building is higher, the author rules out that Zeta build environment-unfriendly building and should be offer a second chance as their contractor. However, the author made an assumption that these two buildings suffer the same climate. Because if Zeta’s building is located in a cold place , people need to use heater or air conditioner to keep warm. In fact, building’s energy consuming is more based on climate and people’s need. Since the climate information is missing. We cannot attribute it to Zeta’s construction mistake. In addition, we are not informed about how many people are there in those two buildings. The comparison of energy consuming might be bias. Therefore, the authors reasoning is questionable.
Moreover, Even if the assumptions mentioned above are valid, the writer’s recommendation could be doubtful due to the assumption regarding the Alpha’s employees keeps its workforce stable. Claiming that Alpha’s workforce is more stable with the evidence that less alpha’s employee turnover, the author lead us to a conclusion that Alpha is a better option as a contractor. Workforce doesn’t depend on rate of reassignment but qualified employees. It is unreasonable to assume that the employees remain staying in Alpha are efficient and it is them keeping the workforce stable. For there is a possibility that the qualified employees left Alpha for better opportunities and the ones remains just dawdle around. Zeta, on the other hand, has a more fluctuate rate of unemployment, it is possible that they fired unqualified workers and hire good ones. If so, the author’s claim will be seriously challenged.
To summarize, whether or not we should implement the writer’s recommendation depends greatly on the validity of the assumptions in the argument. If these assumptions prove unwarranted, then the recommendation will be little more than the writer’s wishful thinking, and accordingly we need to completely consider the ways to value a qualified constructor. |
