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 sub minimum 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 1970’s than it did in the 1960’s.（B）
(E) The teenage unemployment rate has occasionally declined in the years since 1960.
这道题A,C,D,E很容易排除，可是B并不能 most weaken the argument 呀。原文说是更低的minimum wage能失业率不再增长。B说 minimum wage 保持不变，失业率还在上升，但并不能代表minimum wage 减小后，失业率仍将上升啊！请NN指点。
