107 The following is a memo from the business manager of Valu-Mart stores.
"Over 70 percent of the respondents to a recent survey reported that they are required to take more work home with them from the workplace than they were in the past. Since Valu-Mart has not seen impressive sales in its office-supply departments in the past, we should take advantage of this work-at-home trend by increasing at all Valu-Mart stores the stock of home office machines such as printers, small copy machines, paper shredders, and fax machines. We will also increase stock of office supplies such as paper, pens, and staplers. With these changes, our office-supply departments will become the most profitable component of our stores."

【题目拆析】
论点：With these changes, our office-supply departments will become the most profitable component of our stores.
论据：
1。Over 70 percent of the respondents to a recent survey reported that they are required to take more work home with them from the workplace than they were in the past.
2。Since Valu-Mart has not seen impressive sales in its office-supply departments in the past, we should take advantage of this work-at-home trend by increasing at all Valu-Mart stores the stock of home office machines such as printers, small copy machines, paper shredders, and fax machines. We will also increase stock of office supplies such as paper, pens, and staplers.
【攻击分析】
论据1
A.首先有一个survey，那么就条件反射式的要问：1）这项survey是谁做的？2）如何做的？3）数据如何处理的？4）权威性和可信度如何？这里的arguer没有提及
B. survey的feedback到底有多少？如果调查问卷有10000份，但是如果只有3份feedback呢？这里arguer没有提及
C.作出feedback的答卷人的职业分布没有说明。他们是否能代表绝大多数的行业和职业？如果他们仅仅来自某些特殊行业，那么他们的这些变化放到整个社会是很微小的、很难说明什么问题。
论据2
A.首先，arguer说” we should take advantage of this work-at-home trend by increasing at all Valu-Mart stores the stock of home office machines such as printers, small copy machines, paper shredders, and fax machines. We will also increase stock of office supplies such as paper, pens, and staplers”.他的这个结论是基于假设论据1中所提到的“越来越多的人们开始在家办公，需要很多办公用品”，但是这个假设还未被证实。
B.即使假设1被证实，那么所需要的办公用品的市场规模到底有多大？市场饱和程度如何呢？
结论
A.结论说“With these changes, our office-supply departments will become the most profitable component of our stores.”但是，办公用品是否有利润？利润是否最大化？这些arguer都没有给出足够证明。
