Question ID:PT9 S4 Q10 Passage:Myrna: People should follow diets in which fat represents no more than 30 percent of total calories, not the 37 percent the average diet in this country contains. Roland: If everyone in the country followed your recommendation during his or her entire life, just 0.2 percent would lengthen their lives at all, and then only by an average of 3 months.
