2.The average life expectancy for the United States population as a whole is 73.9 years, but children born in Hawaii will live an average of 77 years, and those born in Louisiana, 71.7 years. If a newlywed couple from Louisiana were to begin their family in Hawaii, therefore, their children would be expected to live longer than would be the case if the family remained in Louisiana.
Which of the following, if true, would most seriously weaken the conclusion drawn in the passage?
A. Insurance company statisticians do not believe that moving to Hawaii will significantly lengthen the average Louisianan’s life. B. The governor of Louisiana has falsely alleged that statistics for his state are inaccurate.
C. The longevity ascribed to Hawaii’s current population is attributable mostly to genetically determined factors.
D. Thirty percent of all Louisianans can expect to live longer than 77 years. C
E. Most of the Hawaiian Islands have levels of air pollution well below the national average for the United States. 对于B，og的解释：Because the governor’s allegation is false, it cannot affect the conclusion. 可能精确地说这是一个语法问题。仔细看了一下 B. The governor of Louisiana has falsely alleged that statistics for his state are inaccurate. 双重否定不是等于肯定吗？也就是说，The governor of Louisiana 的统计是对的。 怎么和og的解释矛盾？ 盼解答，谢谢，先！：）
你理解错了，B. The governor of LACE>LouisianaLACE> has falsely alleged that statistics for his state are inaccurate的意思是政府错误地声称统计是错误的。可见这个统计不是The governor of LACE>LouisianaLACE> 做出来的，如果是他做的，他不会自己打自己的嘴巴说自己统计数据错了。
