### HideShow timer Statistics

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
Louisiananâ€™s life.
B. The governor of Louisiana has falsely alleged that statistics for his state are inaccurate.
C. The longevity ascribed to Hawaiiâ€™s current population is attributable mostly to genetically determined factors.
D. Thirty percent of all Louisianans 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.

Clear C. If it's genetics, then it doesn't matter where you move your family to.

Yup it is C.

If the longevity at Hawaii is due to genetically determined factors, then there is no affect on people migrating in on their longevity ..

becausse, if the longevity is decided by genes, then living in hawai will not increase the life span.

agree with C , if genetics is the determinate then it really doesn't matter where you live.

The sentence is weakened when we ascribe the longetivity of Hawaiian to genetically determined factors.
Despite their migration to Hawaii, children born in Louisiana will not be able to increase their life span .

I like C. If most people living in Hawaii are of asian decent and people living in Louisiana is of caucasian decent, then it would be attributable to the genes rather than the area itself. Just an example I used.
