1. 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?
A Health care spending in the United States should be reduced by 50%.
B More expensive health care causes a higher incidence of certain diseases.
C The money spent on health care in the United States is not being used effectively.
D The average health care spending for middle-aged white Americans is probably less than the average health care spending for Americans in general.
E Something other than diet, exercise, smoking, and drinking must account for the difference in health for the two groups in the study
2. Spokesperson: In the 2006 election of the city mayor, 55% of the voters were female. All the voters were between ages 18 and 70 and 2/3 of them supported the incumbent mayor. The incumbent mayor won the election with a substantially greater number of votes than any other candidate.
If the statements made by the Spokesperson are true, then which of the following must be true?
A At least 1/2 of the female voters supported the incumbent mayor.
B The incumbent mayor received stronger support from the female voters than from the male voters.
C There were no other candidates in the election who received more than 30% of all the votes.
