Answer
Brief Explanations:
GDP is a total - value measure. When comparing productivity among countries, differences in population size matter. A large - population country may have a high GDP just due to more people working, not necessarily higher productivity per person. Options A, B, C, and D do not directly address the fundamental issue of comparing productivity across countries as much as population size does.
Answer:
E. Different population sizes, such as China, Japan, and the United States
