8. Teenagers are often priced out of the labor market by the government-mandated minimum-wage level because employers cannot afford to pay that much for extra help. Therefore, if Congress institutes a subminimum wage, a new lower legal wage for teenagers, the teenage unemployment rate, which has been rising since 1960, will no longer increase.
Which of the following, if true, would most weaken the argument above?
(A) Since 1960 the teenage unemployment rate has risen when the minimum wage has risen.
(B) Since 1960 the teenage unemployment rate has risen even when the minimum wage remained constant.
(C) Employers often hire extra help during holiday and warm weather seasons.
(D) The teenage unemployment rate rose more quickly in the
(E) The teenage unemployment rate has occasionally declined in the years since 1960.
我选的C，if not in holiday and warm weather seasons，the teenage unemployment rate will rise again,since less teenagers imployed
答案B, unemployment rate has risen when minimum wage remained constant 对提干when minimum wage lower ，unemployment rate will no longer increase 应该没有WEAKEN 吧
我觉得B在暗示 有他因导致失业率上升，并不是工资高低的问题 所以削弱了
C 推理主要在说工资低导致童工失业率高 而且是1960--法案出台前 与 法案出台后比较 C这个选项一是比较的时间范围不对（holiday& warm weather season）,二是hire extra help不能weaken工资影响失业率阿
一点点我的看法
