The 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(1,5), and today low-fat products abound in many food stores(2). Since many of the food products currently marketed by Old Dairy Industries are high in fat and cholesterol(7), the company's sales are likely to diminish greatly and their profits will no doubt decrease(3,4). We therefore advise Old Dairy stockholders to sell their shares and other investors not to purchase stock in this company(6)."
（1）The author fails to assure us that the survey results accurately reflect the desires of most consumers, or that the results accurately predict consumer behavior. (Are the respondents representative?
（2）The fact that low-fat foods are in abundant supply in food stores does not necessarily indicate an increasing demand for low-fat dairy products or a diminishing demand for high-fat dairy products.
（3）The newsletter concludes too hastily that Old Dairy profits will decline.
（4）The argument fails to provide any information about other products marketed by Old Dairy which may be low in fat and cholesterol.
（5）The author fails to consider other factors that may influence the consumers’ decision in choosing food.
（6）The mere fact that many Old Dairy’s food products are high in fat and cholesterol does not necessarily prove that their stock is not worth investing.
（7）The author ignores the possibility that Old Dairy may change its policy and main product in the future.
