今天小编为大家分享的GMAT逻辑题的重要战术，希望通过这篇文章的学习对你们有所帮助，下面跟随小编一起学习吧。
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.
(注释：priced out of the market：因价高而被挤出市场)
Which of the following statements, 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.
看完问题，发现是削弱题;再读原文，意思不难，很快提炼出其逻辑为
如果国会制定更低的teenagers低工资 teenagers的失业率将不再上升 显然，正确选项首先要涉及低工资和失业率之间的关系，而其他内容则为无关信息，可以排除
显然A 和B都是相关的 而C在谈季节问题，D和E没有涉及失业率快慢的原因，都与原文逻辑无关，通通排除。
所以只需要仔细审视A和B

A “低工资上升的时候，失业率上升”，这与原文逻辑(更低工资将导致失业率不上升)形成了“反因反果”的关系，所以是加强。(比如：“不长跑的人不长寿”加强了“长跑的人长寿”) 这样A就被排除了，所以答案只能是B
当你真正面对GMAT逻辑推理题时，就不那么轻松，因为有时间所限。尤其是GMAT逻辑题难题，运用严格的逻辑推理思维来做，往往耗时甚多。尤其是五个选项逐一论证更是不切实际。所以对于GMAT逻辑题，我们必须要培养一种GMAT逻辑推理感觉，依靠这种GMAT逻辑推理感觉，我们可以很快地将一些无关项排除掉。那这种GMAT逻辑推理感觉除了靠大量练习来培养外，更应通过察觉选项中的“无关信息”，迅速做出判断，将之排除。
