The top five countries in wine consumption and their consumptions (in millions of gallons) are described by the three- dimensional graph in Fig. 133.

a. What is confusing about the three-dimensional graph?
b. The correct wine consumptions are given in Table 52. What type of graph could describe the percentages in a straightforward way? Construct such a graph.

c. Although the United States' wine consumption was greater than France's, the United States' population is much greater than France's. Calculate the wine consumption per person for the United States and for France. Which country has the larger consumption per person?
d. Find the wine consumption per person for Italy, Germany, and China. Of the five countries listed in Table 52, which country has the largest wine consumption per person? The least?
e. Even though the countries included in Table 52 are the top five countries in wine consumption, it is possible, in theory, for some other country to have the largest wine consumption per person of any country in the world. Explain why this is possible. What would be that country's largest possible population?
