The two-party system has worked in the United States, but not in Europe, because

• A. Americans are more aggressive and less deferential.
• B. Fewer Americans want to participate in party activities.
• C. Americans agree on enough issues to form broad coalitions.
• D. Americans are more economically conservative than Europeans.

Answer: (C)

A broad political consensus among Americans that allows two big coalitions to appeal to a wide range of voters is what makes the two-party system work in the United States. When most people share common views on major issues, it’s easier for two parties to capture the center and attract a large majority, keeping third parties from breaking through in a meaningful way under winner-take-all rules. Europe, by contrast, tends to have a wider diversity of views and uses proportional representation, which makes it easier for multiple parties to gain seats and form coalitions, rather than forcing a single dominant pair. The option that attributes the system to Americans agreeing on enough issues to form broad coalitions captures this essential dynamic. The other statements miss the core structural reason, focusing on personality, participation, or economic views instead of how broad alignment shapes party competition.
