Passage Summary: Even though Britta seemed like the winner because she knew more facts, the coach thinks Robert did just as well because his logic was better.

Conclusion: Robert's overall performance in the debate was equal in quality to Britta's performance.

Reasoning: Although Britta had a better grasp of historical facts, Robert's arguments were more reasonable, and reasonableness should be considered alongside factual command.

Analysis: The coach is attempting to balance two different metrics: factual knowledge and logical reasonableness. For the conclusion to hold that they are 'as good' as one another, the coach must assume that Robert's superior reasonableness is enough to compensate for Britta's superior factual knowledge. If facts were the only thing that mattered, or if they were significantly more important than logic, the coach couldn't claim the performances were equal. Look for an assumption that bridges the gap between these two distinct criteria to justify the 'equal' rating.
