Passage Summary: Rebel political groups are made of different factions that hate each other just as much as they hate the government; they only play nice to win, so they'll start fighting the moment they take power.

Conclusion: The internal unity of an insurgent political party is likely to dissolve once they successfully overthrow the dominant party.

Reasoning: These parties are composed of factions with conflicting goals that only cooperate to defeat a common enemy, and these conflicts resurface immediately after victory.

Analysis: This stimulus sets up a 'ticking time bomb' scenario for insurgent parties. Since the only thing holding these disparate factions together is a shared enemy, the removal of that enemy logically leads to the return of internal strife. We are looking for a conclusion that flows naturally from this inevitable conflict. Look for an answer that predicts post-victory instability or the inability of the winning party to maintain a unified front.
