请教大全-2-8，绕晕了~~~

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.（没说）

(B) Since 1960 the teenage unemployment rate has risen even when the minimum wage remained constant.（=government-mandated minimum-wage level。以前工资保持不变不雇佣数量就一直上升，异因同果）

(C) Employers often hire extra help during holiday and warm weather seasons.（违反前提cannot afford to pay that much for extra help.）

(D) The teenage unemployment rate rose more quickly in the 1970’s than it did in the 1960’s.（无关比较）  （B）

(E) The teenage unemployment rate has occasionally declined in the years since 1960.（无关）

这是我以前做的时候标记的，今天再做的时候发现怎么也觉得B想不通了。

以前维持最低工资时评的时候失业率也上升，和现在再降低工资失业率不上升有什么关系啊？

原文说最低工资的时候employers cannot afford to pay that much for extra help，那现在降低工资不就can afford了吗？我怎么也绕不出来B了，大家帮忙啊~~~头痛~~

我一直觉得C挺好，C是说teenagers一般都在假期打工，即使政府规定一个较低的submininum wage效果也不会太大。

B我怎么也想不通，文中没说mininum wage变化会有什么影响。

果然比较晕，等个nn来解一下吧。帮你顶。

是啊，我一开始也是选B，麻烦哪位NN来答疑啊~~~

呼叫斑竹~~

我这样理解：

题干：government-mandated minimum-wage level太高，使得employers不能负担雇佣teenager的劳务费用，造成teenager employment rate持续降低。所以建议订立一个低一点的minimum-wage level，来阻止teenager employment rate降低。

B说teenager emloyment rate 降低实际与minimum-wage level无关，所以，Conggress的新措施也就无效了。

说错了，我一开始选的C...

谢谢papa，但是为啥C不行呢？

此题是选相对最ｗｅａｋｅｎ的，和大家心里的答案不一样很正常

(A) Since 1960 the teenage unemployment rate has risen when the minimum wage has risen.

有可能是其他原因造成的，而不是必然可以归结到ｍｉｎｉｍｕｍ　ｗａｇｅ

(B) Since 1960 the teenage unemployment rate has risen even when the minimum wage remained constant.

就是说肯定有其他原因提高了ｕｎｅｍｐｌｏｙｍｅｎｔ　ｒａｔｅ

(C) Employers often hire extra help during holiday and warm weather seasons.

不能和ｕｎｅｍｐｌｏｙｍｅｎｔ　ｒａｔｅ联系起来

(D) The teenage unemployment rate rose more quickly in the 1970’s than it did in the 1960’s.无关

(E) The teenage unemployment rate has occasionally declined in the years since 1960.无关

注意：一定要根据题干中提供的信息作为推理的基础，大家选ｃ可能是自己加入了一些主观的判断，而题干中根本没有提到任何关于ｈｏｌｉｄａｙ　ａｎｄ　ｗａｒｍ　ｗｅａｔｈｅｒ　ｓｅａｓｏｎｓ的信息

(B) Since 1960 the teenage unemployment rate has risen even when the minimum wage remained constant.

就是说肯定有其他原因提高了ｕｎｅｍｐｌｏｙｍｅｎｔ　ｒａｔｅ

我觉得不一定是其他原因导致，也有可能就是因为这个minimum对于雇主而言太高，所以即使它保持不变，学生的失业率也还是在增加。

请哪位nn路过指教

agree with bedroom

原文结论： Unemployment  no increase

要削弱：就找，unemployment increase ,只要不是原文的原因就可以
