Question

supporters of prohibition expected that prohibition would
encourage people to become religious.
increase the violent crime rate.
fix the problems of society.
put liquor distillers out of business

Explanation:

Prohibition in the U.S. was backed by groups who believed banning alcohol would eliminate issues like poverty, domestic abuse, and social decay that they linked to drinking, framing it as a solution to broad societal problems. The other options are incorrect: supporters did not aim to make people religious, they did not expect increased violent crime (that was an unintended consequence), and putting distillers out of business was a means, not the main expected outcome.

Answer:

fix the problems of society.
