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 1970’s than it did in the 1960’s.
(E) The teenage unemployment rate has occasionally declined in the years since 1960.

The answer is B, but I think B strongthens the argument. Why E is wrong?

工资本来就太高,所以即使不变,它还是太高啊!当然失业率上升.所以调降工资让企业愿意用人,失业率就
                no longer increase 啦! 这不是
                support 吗? 注意题目不是假设语气,调降工资根本还未实施. 1960的工资水平是依照"旧"的规定.

(E) 不降工资,失业率也会下降,不就弱化了"降工资,失业率不上升"吗? 即使失业率只偶然小小的降了一下(e.g.用人孔急企业不得不屈就),那也绝不是降工资造成的吧?更证明"降工资,失业率不上升"是胡扯,不是吗?
