In the United States, about $5,200 per person per year is spent on health care, while in Britain the amount is about
half that. A recent study indicated that middle-aged white Americans have a significantly higher rate of diabetes
and heart disease than do middle-aged white Britons. Even after eliminating from the study the lifestyle differences
of diet, exercise, smoking, and drinking, the data showed that the Americans have poorer health than their British
counterparts. The statements above, if true, best support which of the following assertions?
Health care spending in the United States should be reduced by 50%.
More expensive health care causes a higher incidence of certain diseases.
The money spent on health care in the United States is not being used effectively.
The average health care spending for middle-aged white Americans is probably less than the average health care

Something other than diet, exercise, smoking, and drinking must account for the difference in health for the two
groups in the study.

45% of the voters in the election were male and none of them were 75 years old.
If the proportion of male and female voters in the city remains the same, the incumbent mayor is also likely to win
the next election.
