PrepTest 94+, Section 2, Question 10
Medical researcher: Studies in North America have shown that the incidence of heart disease in a population is closely related to the average fat consumption for individuals in that population. However, although residents of France consume, on average, as much fat as residents of North America, heart disease presently occurs half as frequently among the French as among North Americans.

Which one of the following, if true, would most help to resolve the apparent conflict noted by the medical researcher?
The average level of fat consumption by the French has been falling for several decades.
Other factors of diet besides high consumption of fat have not been similarly linked with incidence of heart disease.
Heart disease takes years to develop and the average level of fat consumption in France increased to North American levels only a few years ago.
Certain diseases other than heart disease have also been linked to average fat consumption, and the French have a higher incidence of these than do North Americans.
Cigarette smoking significantly increases the risk of heart disease and France has a higher percentage of cigarette smokers in its population than does North America.
