Passage Summary: Usually, politicians agree on bills or find a middle ground. However, if a bill touches on a core, fundamental issue for a large group, they cannot reach a compromise.

Reasoning: Most bills have majority support; if they don't, compromise is usually possible unless the bill involves a fundamental issue for a large group of representatives.

Analysis: To find what must be false, we need to find a statement that violates the rules established in the text. The most absolute rule here is that compromises are impossible when a bill concerns a fundamental issue for a large bloc. Look for an answer that describes a scenario where a compromise was reached despite these specific conditions being met. Since the stimulus is a set of facts about political behavior, we must treat these constraints as unbreakable laws for the purpose of this question.
