Black Americans are, on the whole, about twice as likely as White Americans to develop high blood pressure. This likelihood also holds for westernized Black Africans when compared to White Africans.
Researchers have hypothesized that this predisposition in westernized Blacks may reflect an interaction between western high-salt diets and genes that adapted to an environmental scarcity of salt.
Which of the following statements about present-day, westernized Black Africans, if true, would most tend to confirm the researchers’ hypothesis?
(A) The blood pressures of those descended from peoples situated throughout their history in Senegal and Gambia, where salt was always available, are low.
(B) The unusually high salt consumption in certain areas of Africa represents a serious health problem.
(C) Because of their blood pressure levels, most White Africans have markedly decreased their salt consumption.
(D) Blood pressures are low among the Yoruba, who, throughout their history, have been situated far inland from sources of sea salt and far south of Saharan salt mines.
(E) No significant differences in salt metabolism have been found between those people who have had salt available throughout their history and those who have not.

Please give reasons to support ur answers....

I would go with A.

Quote:
(A) The blood pressures of those descended from peoples situated throughout their history in Senegal and Gambia, where salt was always available, are low.
This goes to show that there is a possibility that only africans who have descended from an area where there is scarcity of salt have high bp.
(B) The unusually high salt consumption in certain areas of Africa represents a serious health problem.
Does not confirm hypothesis in any way.(

C) Because of their blood pressure levels, most White Africans have markedly decreased their salt consumption.
nothing about black africans here
(D) Blood pressures are low among the Yoruba, who, throughout their history, have been situated far inland from sources of sea salt and far south of Saharan salt mines.
opposes hypothesis if they are now with western diet and still have low bp.
(E) No significant differences in salt metabolism have been found between those people who have had salt available throughout their history and those who have not.
does not support hypothesis

D for me. Answer should emphasize the fact that Africans have low BP because they live in places where Salt is scarce. D is the only one that does that.

Going with D
A provides the information for people who are adapted to salt available environment.
