题目：
The following appeared in a health magazine published in Corpora.
Medical experts say that only one-quarter of Corporas citizens meet the current standards for adequate physical fitness, even though twenty years ago, one-half of all of Corporas citizens met the standards as then defined. But these experts are mistaken when they suggest that spending too much time using computers has caused a decline in fitness. Since overall fitness levels are highest in regions of Corpora where levels of computer ownership are also highest, it is clear that using computers has not made citizens less physically fit. Instead, as shown by this years unusually low expenditures on fitness-related products and services, the recent decline in the economy is most likely the cause, and fitness levels will improve when the economy does.
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：
医学专家指出C市只有四分之一的市民达到了目前的健康标准，尽管20年前，C的市有一半都达到了那时由国家制定的健康标准。同时专家们认为长时间的使用电脑可能是导致这一现象的原因，但这样的解释可能是错的。由于C市是电脑拥有量最高的地区也是总体健康水平最高的地区，显然使用电脑并没有导致市民体质的下降。相反，今年用于健身产品和服务的花费低的异乎寻常，这表明最近经济的衰退最可能是原因，当经济复苏了健康水平也会随之提高。
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。
