gre argument 176题目：
The following is a memorandum from the sales director to the president of the Healthy-and-Good food company.
"A recent study indicates that Venadial, a new margarine currently produced only in the country of Alta, actually reduces cholesterol levels. Derived from the resin of pine trees, Venadial works by activating a metabolic response that is not yet well understood(4). However, cholesterol levels fell ten to fifteen percent among participants in the study who consumed Venadial daily(2), and the risk of heart attack by one-third(1,3). In addition, the new margarine is so popular that stores in Alta(5) are unable to keep it on their shelves. Therefore, if our company obtains the exclusive right(6) to sell Venadial internationally(7), our profits are sure to increase substantially within a very short time."
提纲：
(1)The director fails to establish a causal relationship between the consumption of Venadial and the fallen cholesterol levels and the risk of heart attack among the participants.
(2)The study fails to include another group of people who do not consume Venadial as a counterpart.
(3)We are not informed about the actual procedure of the study, thus the reliability of the method used by the study to determine the risk of heart attack is questionable.
(4)Since the process of how Venadial works is not well understood yet, we cannot evaluate if Venadial has any health benefits, or if there is any negative effect of consuming Venadial.
(5)The fact that Venadial is very popular in Alta does not guarantee that it will also be popular all over the world.
(6)The director fails to inform us about the cost of obtaining the exclusive right and manufacturing and distributing Venadial, thus we cannot evaluate if the profits will necessarily increase substantially in a short time.
(7)The director fails to consider if the consumers in other regions and other countries will accept margarine.
