Doctor: Research shows that adolescents who play video games on a regular basis are three times as likely to develop carpal tunnel syndrome as are adolescents who do not play video games. Federal legislation that prohibits the sale of video games to minors would help curb this painful wrist condition among adolescents.
The doctor’s conclusion depends on which of the following assumptions?

A The majority of federal legislators would vote for a bill that prohibits the sale of video games to minors.
B Not all adolescents who play video games on a regular basis suffer from carpal tunnel syndrome.
C Playing video games is the only way an adolescent can develop carpal tunnel syndrome.
D Most parents would refuse to purchase video games for their adolescent children
E The regular playing of video games by adolescents does not produce such beneficial effects as better hand-eye coordination and improved reaction time.
正确答案：D（非常非常确定，小心变体）



谁能帮我讲下为什么选D~C又为什么不对呢？？

lawyer里面典型的否定它因
假设题常用的两种做法
1.弥补推理gap
2.否定它因，就是否定题目条件之外会对结论有影响的条件，选项里一般会出现否定词，比如not, no等-gwd里面这种很多哈
