  为了让我们更好的适应GMAT考试,GMAT考试官网每天都会有GMAT试题,下面是澳际小编为您整理的2016年7月13日GMAT考试题目,是逻辑题,让我们一起来看一看这道题目吧。

  "Life expectancy" is the average age at death of the entire live-born population. In the middle of the nineteenth century, life expectancy in North America was 40 years, whereas now it is nearly 80 years. Thus, in those days, people must have been considered old at an age that we now consider the prime of life.

  Which of the following, if true, undermines the argument above?

  A、In the middle of the nineteenth century, the population of North America was significantly smaller than it is today.

  B、Most of the gains in life expectancy in the last 150 years have come from reductions in the number of infants who die in their first year of life.

  C、Many of the people who live to an advanced age today do so only because of medical technology that was unknown in the nineteenth century.

  D、The proportion of people who die in their seventies is significantly smaller today than is the proportion of people who die in their eighties.

  E、More people in the middle of the nineteenth century engaged regularly in vigorous physical activity than do so today.

  澳际培训提醒各位参加准备GMAT考试的同学,仔细看完以上的GMAT试题,然后再看下面的GMAT考试题目答案更有效哦。

  答案:B。分析:

  看原文,先介绍了life expectancy的概念,接着说在19世纪中叶,北美的平均寿命是40岁而现在是80岁,THUS,在那些年,人们对于老的观点不同,就是在那时候他们认为老的年纪我们现在认为是年轻的。求weaken。

  看选项 A 在十九世纪中叶,北美的人口怎么着,原文从头到尾都在讨论寿命问题,没讨论人口,排除。

  B 他因有效weaken,正确

  C 没说到medical technology,并且也不能有效weaken,排除。

  D proportion没说到,weaken无效,排除。

  E 没说体育锻炼,且weaken无效,排除。
