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.
2. 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 Louisianian’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 Louisianians can expect to live longer than 77 years
(E) Most of the Hawaiian Islands have levels of air pollution well below the national average for the United States.
Because the conclusion concerns people born in Hawaii, not the average Louisianan, A does not weaken the conclusion. Because the governor’s allegation is false, it cannot affect the conclusion. D fails to weaken the conclusion because it is consistent with the information given and the conclusion about life expectancy. By suggesting that Hawaii’s environment is in one respect particularly healthy, E supports the conclusion.
黄色的提亮部分，我认为conclusion concern的是people born in Lousianan,而不是Hawaii.因为在题目的conclusion是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
因此，是和Lousianan有关，而不是Hawaii.请指教。
