15The following appeared in a newsletter offering advice to investors.
"Over 80 percent of the respondents to a recent survey indicated a desire to reduce their intake of foods containing fats and cholesterol, and today low-fat products abound in many food stores. Since many of the food products currently marketed by Old Dairy Industries are high in fat and cholesterol, the company's sales are likely to diminish greatly and their profits will no doubt decrease. We therefore advise Old Dairy stockholders to sell their shares and other investors not to purchase stock in this company."
1. Survey: how many respondents? Are they representative? Do they have a preference?
2. Low-fat products abundant ≠ more low-fat food demands or less fat-food demands
3. The arguer fails to consider other factors that influence food selection. (OD high food ≠ diminishing sales, less profit)
4. 即使high-fat≠ OD’s stock is not worth investing.
5. The arguer ignores the very possibility that OD may change its policy and tend to provide low-fat food in the future.
