gre argument 76题目：
The following appeared as part of an article in a health and beauty magazine.
"A group of volunteers (1) participated in a study of consumer responses to the new Luxess face cream. Every morning for a month, they washed their faces with mild soap(2) and then applied Luxess. At the end of that month, most volunteers reported a marked improvement in the way their skin looked and felt(3). Thus it appears that Luxess is truly effective in improving the condition of facial skin (4)."
提纲：
(1)The volunteers may not be representative of all consumers using Luxess.
(2)The author fails to rule out the possibility that it is the mild soap that actually improved the condition of the volunteers’ facial skin.
(3)The volunteers may have misunderstanding about the condition of their facial skin.
(4)The author fails to consider possible negative effects of Luxess.
