题目题材：医疗保健
gre argument 96题目：
The following appeared in a magazine focusing on health and fitness.
A recent study of several nutritional supplements showed that subjects who took a daily pill containing luceen had significantly better vision of distant objects than subjects in the study who took other nutritional supplements. Luceen appears naturally in a tasty fruit that grows on the island of Bonopia, and very few inhabitants of that island wear eyeglasses or other corrective lenses. Such evidence suggests that people who develop vision problems should take regular luceen supplements.
提纲：
The author fails to consider other possible difference between the two groups of subjects.
The author does not point out the actual and exact effect of luceen on vision.
The fact that few inhabitants of Bonopia wear eyeglasses or other corrective lenses does not prove that most inhabitants there have good vision.
Granted that most inhabitants of Bonopia do have good vision, we cannot ensure that luccen in the fruits is the reason.
The author fails to consider possible negative effects of taking luceen supplements.
The author hastily assumes that taking luceen supplements could cure other vision problems.
There may be other better treatment for vision problems.
