Each of the following quotes is taken from an article titled, "Education seems to help in selecting husbands" (Sacramento Bee, December 4, 1998, p. A21), which reported on new data in the Statistical Abstract of the United States. Draw an appropriate graph to represent each situation.

a. "The data show that 3.8 percent of women who didn't complete high school had four or more husbands. For high school graduates, the share with four or more partners drops to 3 percent. Among those who attended college 2 percent had four or more husbands, and that fell to 1 percent for those with college degrees."

b. "From 1997 on, 5.5 percent of children lived with their grandparents, a share that has been rising steadily. It was only 3.6 percent in 1980, and by 1990 it was 4.9 percent."

c. "The center said 20.1 percent of Americans took part in some regular activity-21.5 percent of men and 18.9 percent of women."
