关于argument 1的一些疑问

lktc382UID: 2695759

题干：

The following appeared in a memorandum written by the vice president of
Nature's Way, a chain of stores selling health food and other
health-related products.

"Previous experience has shown that our stores are most profitable in
areas where residents are highly concerned with leading healthy lives. We
should therefore build our next new store in Plainsville, which has many
such residents. Plainsville merchants report that sales of running shoes
and exercise clothing are at all-time highs. The local health club, which
nearly closed five years ago due to lack of business, has more members
than ever, and the weight training and aerobics classes are always full.
We can even anticipate a new generation of customers: Plainsville's
schoolchildren are required to participate in a 'fitness for life'
program, which emphasizes the benefits of regular exercise at an early
age."

根据我手头上的一份提纲

A. The author's conclusion that they will make profits in Plainsville is based on the gratuitous assumption that people who are enthusiastic about exercising will necessarily be interest in buying health food and other health-related products.

B.A problem in this argument is that it simply concludes that people who are concerning about healthy lives will automatically became Nature's Way's customers. Even if many people in P are interest about health food and other health-related products, the author ignores other factors that may affect the business of NW, such as the presence of competitors, the population of the area, and the eating habits of the local residents.

C. Another problem in this argument is that the author simply equates strong sales of running shoes and exercise clothing to the residents' interests of sports.

D. The large number of club members does not necessarily indicate that they will become the customers of NW.

E. The argument's conclusion that NW will make profits is unwarranted. Profit is a factor of not only revenue but also costs.

F. Another problem with the argument is that the author's conclusion that residents' enthusiasm about health lives will remain unchanged in the future rests on the unfounded assumption that all conditions upon which people's interests depend have remained unchanged.


个人认为B、E、F是没什么问题的，但是如果C放在A前面形成3断让步是不是更好呢？
而且A中的enthusiastic about exercising是作者没有提到的，换句话说这是我们加上去的中间推断，有乱扣帽子的嫌疑！
我觉得其实文中提到的“sales of running shoes and exercise clothing are at all-time highs. The local health club, which nearly closed five years ago due to lack of business, has more members than ever, and the weight training and aerobics classes are always full. ”。
我觉得作者想要说的应该是P地的人“highly concerned with leading healthy lives”
请达人帮忙解答啊！

In addition, you should consider the structure of the argument—the way in which these elements are linked

together to form a line of reasoning; that is, you should recognize the separate, sometimes implicit steps in

the thinking process and consider whether the movement from each one to the next is logically sound.

“enthusiastic about exercising”的确是作者没有提到的，但个人认为属于“the separate, implicit steps”

3个基础论据-->(Enthusiastic about exercising =)Highly concerned with leading healthy lives+Previous Experience-->(...implicit too)Profitable

作者中间的推断的确是想说P地“highly concerned with leading healthy lives”
可惜作者举出的3个论据并不能很好地支持“关心健康”这个臆断，三个论据最多只能推出关心运动，但作者忽略了“关心运动”并不等于“关心健康”，我们要做的正是指出逻辑链中的断裂之处,所以不能说这是乱扣帽子。（此处也可以说是作者无意间做了个没有根据的假设）

ARGUMENT TASK其中一个很重要的任务就是找到implicit steps，通常都会牵扯出unmentioned assumption，你可以说这是作者"overlook or choose to ignore"的后果。

关于顺序问题～

Or you might want to first point out a central questionable assumption and then move on to discuss related flaws in the argument's line of reasoning.
