Final answer:
Asian or Asian American individuals tend to abstain from alcohol because of a biological reaction to alcohol, and Asian Americans are often stereotypically referred to as the 'model minority.' Nonminority males with higher incomes tend to vote more, and the temperance movement relates to social changes such as urbanization and immigration.
Step-by-step explanation:
The population group that tends to drink very little or abstain from alcohol due to a biological reaction is Asian or Asian American. This reaction is often the result of a genetic variation that affects alcohol metabolism, leading to unpleasant effects after drinking alcohol, including facial flushing and increased heart rate. This genetic variation is relatively common among people of East Asian descent. In the context of the term "model minority," this is often a stereotype applied to Asian Americans, who are perceived to achieve a higher degree of socioeconomic success than the average population, often to the exclusion of their own unique challenges. As for voting behavior, nonminority males with higher incomes are statistically more likely to vote in elections. Lastly, the temperance movement, which advocated for moderation or complete abstinence from alcohol consumption, is indeed a response to changing social conditions, including the effects of urbanization and immigration, making the statement in the question true.
