According to a different source, these are the options that come with this question:
One key difference between the U.S. system of government and a multiparty system of government is that in the U.S. system, coalition governments cannot be formed.

Coalitions are usually formed in countries that operate under the principle of proportional representation, as most of the time, no political party can achieve a majority on its own.
