(d) how many quadrillion btu were consumed from geothermal? click the icon to view the graphic. (a) choose the correct answer. a. the data are quantitative. b. the data are qualitative. c. the data make up parts of a whole. d. the data contains more than one category.

Explanation:

A pie chart is used to represent data that consists of parts of a whole, where the sum of all parts equals the total. In the case of U.S. primary energy consumption, different energy sources (like geothermal, nuclear, etc.) are parts of the total energy consumed. Option A is incorrect because pie charts can represent qualitative or quantitative data related to parts of a whole, not just quantitative. Option B is incorrect as the key reason for a pie chart here is the parts - whole relationship, not just that data is qualitative. Option D is incorrect because having multiple categories is not the defining reason for a pie chart; the key is that the categories are parts of a whole. So the correct answer is C.

Answer:

C. The data make up parts of a whole.
