gre argument 113题目：
The following was published by a consumer protection agency.
"Three years ago, So-Low launched a nationwide ad campaign, focusing heavily on sunny regions and distributing free sunglasses there. But although So-Low sunglasses cost less than higher-priced brands, they block a smaller proportion of the Sun's rays, including the type of rays known to damage the eyes even when the person wearing the sunglasses feels no discomfort. A recent study suggests that So-Low sunglasses can actually increase the risk of damage to people's eyes(2) by creating a false sense of security. The study shows a sharp increase in the incidence of vision problems(1) in the sunny regions(3) over the past three years. These findings suggest that anyone concerned about eye damage from the Sun should avoid So-Low brand and instead either pay for higher-priced brands(4) or wear no sunglasses at all(5)."
(1)We need to know detailed information about the vision problems emerged these years to evaluate if they are related to sunglasses.
(2)Granted that these problems are related to sunglasses, we cannot make the hasty inference that it is So-Low that caused them.
(3)The study conducted at the sunny regions may not be representative of all other regions, So-Low could still be suitable for people in other regions.
(4)The author unfairly assumes that the problems caused by So-Low will not take place on higher-priced brands.
(5)The argument ignores other effective solutions besides those proposed by the author.
