Passage Summary: Because getting richer helps people become more free, the negotiator argues that no country should pass laws that stop another country from becoming wealthy.

Conclusion: It is morally wrong for a nation to implement trade policies that would likely damage the economic growth of another nation.

Reasoning: Economic prosperity is a primary driver of political freedom for a country's citizens.

Analysis: This is a Principle Justify question, so we need a rule that bridges the gap between the factual premise (prosperity leads to freedom) and the moral conclusion (it is wrong to hinder prosperity). The argument assumes that because freedom is the end goal, the means to that goal (prosperity) must be protected. Look for an answer that establishes a moral obligation to avoid hindering factors that contribute to political freedom. The correct principle will likely connect the 'wrongness' of an action to its negative impact on the path toward freedom.
