Among multiparty democracies, those with the fewest parties will have the most-productive legislatures.
Conclusion
The multi-party democracies with the fewest number of parties have the most-productive legislatures.
Evidence
The fewer the parties, the more issues they have to take a stand on, so the more they have to prioritize those issues, leading to more compromise.
Evaluation
The conclusion is trying to make this voyage: “Fewest parties → most productive legislature”
The evidence takes us this far: , that never gets discussed in the evidence, we know our job is almost always to figure out what part of the evidence was intended to match up with that new guy in the conclusion.
Goal
Look for something connecting "more compromise" with "more productive legislature"
