GMAT逻辑试题是很有意思的

　　小编为大家带来抽象概念的解析，希望对大家GMAT备考有所帮助。 GMAT逻辑试题是很有意思的，每做一道题，就像玩一个game。但真正面对考试，就不那么轻松，因为有时间所限。日子总会起起落落，有欢笑也会有泪水，有期待当然也会有恐惧，并且试着激励自己也鼓励大家。
　　尤其是难题，运用严格的逻辑思维来做，往往耗时甚多。尤其是五个选项逐一论证更是不切实际。所以对于逻辑题，我们必须要培养一种感觉，依靠这种感觉我们可以很快地将一些无关项排除掉。那这种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。
　　这就是所谓“无关信息排除法”通过选项中出现了与原文内容和推理无关的内容将之迅速排除。常常能排除五项中的三个，再对剩下的选项认真考虑，做出抉择这个方法可以解决GMAT逻辑题读不懂的烦恼。
　　具体实践两道题
　　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.
　　先看完问题，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很低工资，teenagers的失业率将不再上升。
　　显然，正确选项首先要涉及很低的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。
