Final answer:
The Republican Party opposed government expansion to solve social problems in the twentieth century.
Step-by-step explanation:
The political party in the twentieth century that generally opposed government expansion to solve social problems is the Republican Party. The Republican Party has historically favored limited government intervention and promoted individual freedom and small government. They believe that solutions to social problems should be sought through private initiatives and free market forces.
For example, during the 1920s, the Republican Party under President Calvin Coolidge advocated for a laissez-faire economic policy, reducing government regulations and taxes. They believed that the free market would naturally lead to prosperity and that government interference would hinder economic growth.
The Republican Party's stance on limited government intervention continues to be a defining characteristic of the party, although individual politicians within the party may vary in their views on specific social issues.
