Which country is described as ethnically homogeneous with about 98% of the population being ethnically Japanese?

• A. Japan
• B. China
• C. South Korea
• D. Vietnam

Answer: (A)

The idea being tested is ethnic composition and how homogeneous a population is. Japan is described as ethnically homogeneous because the vast majority of people belong to the Japanese ethnic group. About 98% of the population is ethnically Japanese, sharing language, culture, and ancestry. Minorities exist—such as Ainu and Ryukyuan groups, and immigrant communities like Koreans and Chinese—but they are a small portion of the population and do not form large, countrywide groups. That’s why this fits best: other options don’t show that same level of ethnic uniformity. China has 56 recognized ethnic groups with Han people making up roughly 90-plus percent, so there is substantial ethnic diversity. South Korea is also largely homogeneous but not typically described as about 98% ethnically Japanese, and Vietnam, while having a dominant group (Kinh), still has sizeable ethnic minority communities.
