An argument about which company to be chosen In the argument, the writer suggests that the company should use Alpha rather than Zeta for their contemplated new building project. To support his position, the author cites several evidences. On the one hand, the building constructed by Zeta cost more in the expenditure of building, energy consumption and maintenance than the cost of the building constructed by Alpha. On the other hand, the Alpha has a stable workforce with little employee turnover. First of all, the author tells us that the two building are located in different regions with different floor plan. It is impossible to compare the cost and expenditure between two completely different buildings for their energy consumption, maintenance and the building cost. The two buildings have respectively necessary facilities to be built and different environmental conditions to dispose that must result in extremely disparities in all kinds of cost. For example, the building with 10 floors must cost much more than the building with 20 floors in almost every aspect no matter the process of building or the cost of maintenance. It is ridiculous to consider Alapha is better than Zeta based on the cost of the buildings they built in different regions with completely different buildings。 Moreover, the writer cites the stable workforce with employee turnover to support his choice of Alpha. There is no evidence showed that the stable employee's turnover will affect the ability of a company. And the writer does not provide any evidence to support this reason: what investigation is the statement based on? Who conduct the investigation and how? We can not trust the statement that based on no any scientific instigation and enough sample size. Even if the statement about employee turnover is trustable, it is still can not be convinced because the employee turnover is not proved to have nothing to do with the ability of construction. Another problem about the suggestion is that the new contemplated building project has distinct conditions that may different from the two buildings constructed by Alpha and Zeta. The position where the new project locates in is not told and may be in the third region that has great differences with the regions of the other two. Further more, even if the Alpha is better than Zeta, is there any other companies that may have higher ability to compete with them on the task of the new project? Without any conscientious comparison, we can not consider Alpha is the best one to be chosen.
