TOPIC: ARGUMENT41 - The following appeared in a memo from the vice president of a food-distribution company with food-storage warehouses in several cities.
"Recently we signed a contract with The Fly-Away Pest-Control Company to provide pest-control services at our fast-food warehouse in Palm City, but last month we discovered that over $20,000 worth of food there had been destroyed by pest damage. Meanwhile, the Buzzoff Pest-Control Company, which we have used for many years, continued to service our warehouse in Wintervale, and last month only $10,000 worth of the food stored there had been destroyed by pest damage. Even though the price charged by Fly-Away is considerably lower, our best means of saving money is to return to Buzzoff Company for all our pest-control services."

In order to conclude that our best means of saving money is to return to Buzzoff Company(BC) for all our pest-control services, the arguer poses several evidence, such as some logical analyses and a comparison of pest-control effect between the Fly-Away Pest-Contral Company(FPC) and BC. However, I should indicate that these evidence are not strong enough to support the conclusion.
First of all, we cannot judge the pest-control effect of the two companies only by a comparison of the worth of the food stored have been destroyed. Even if we discovered that over $20,000 worth of food in Palm City(PC) have been damaged under the FPC's control while only $10,000 have been lost in the Wintervale(WC) under the BC's protection, we should ask how many they have conserved. It is quite likely that the FPC has prevent $100,000 worth of food from pest damage in PC while BC only protect $20,000 worth of food.
Moreover, it is a fair likelihood that it is the difference of the two cities that determined the different pest damage lost, rather than the ability of the two companies. For example, the climate in PC may be quite hot and humid where is easy to cultivate the pests, while in WC it is cold and dry where the pests are natively fewer than PC.
And also, we could not make the conclusion only on a data of one month. BC, which we have used for many years, is surely more familiar with the environment of the warehouse, while FPC may experience a process of mastering the pest's features. Further more, it is very likely that it has been left fairly bad condition of the warehouse in PC, since FPC has begun to control its pests, and FPC may have tried its best to limit the damage level.
Finally, there is no evidence to say BC is the best choise if without any comparison with other companies, and to hire BC for all our pest control services is also risking that it has not got such ability to deal with all our warehouses in different cities suffering from diversities of the pests.
To sum up, the arguer does not adequately demonstrate the BC is the best or better than FPC, so we can hardly accept his conclusion.
