gre改革后新版gre写作新题库里的作文方面的一个重要变化是有了指导语。而指导语的作用是有助于我们的逻辑性写作，以下是新版gre写作新题库内有关argument117的写作部分：
题目：
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 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 in Palm City, 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 for all our pest control services.
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.
中文翻译：
最近我们和Fly-Away Pest-Control公司签订了一项合同来为我们在Palm City的快餐食品仓库提供杀虫服务，但上个月我们发现，那里有价值超过$20000的食品被害虫破坏。同时，我们使用多年的Buzzoff Pest-Control公司继续在Wintervale的仓库服务，上个月那里只有价值$10000的食品被害虫破坏。尽管Fly-Away的收费低廉的多，我们节省收费的最好方式就是重新使用Buzzoff公司来提供我们所有的杀虫服务。
写一篇回应，在其中检视文章的论证中述及和/或未明确述及的假设，务请解释文章的论证是如何依赖于这些假设的，并指出如果这些假设不成立会对文章的论证带来何种影响。
