LSAT-22-3-10

10.   sychologists have claimed that many people are more susceptible to psychological problems in the winter than in the summer; the psychologists call this condition seasonal affective disorder. Their claim is based on the results of surveys in which people were asked to recall how they felt at various times in the past. However, it is not clear that people are able to report accurately on their past psychological states. Therefore, these survey results do not justify the psychologists’ claim that there is any such condition as seasonal affective disorder.

The author criticizes the psychologists claim by

(A) offering an alternative explanation of the variation in the occurrence of psychological problems across seasons

(B) questioning whether any seasonal variation in the occurrence of psychological problems could properly be labeled a disorder

(C) questioning the representativeness of the population sample surveyed by the psychologists

(D) questioning an assumption that the author attributes to the psychologists（D）

(E) demonstrating that fewer people actually suffer from seasonal affective disorder than psychologists had previously thought

我怎么觉得C比较好?

thanks , litheliluo

但author怀疑psychologist数据的正确性不就是questioning the representativeness of the population sample

那D又该怎么理解?

1。怀疑代表性必须是这些人有其特殊的地方是他们没代表性，原文是说全部的PEOPLE没有那个能力。

2。作者认为心理学家假设了人们能report accurately ，事实上这种能力不清楚。作者怀疑的是这种假设

thanks, lawyer !!
