Passage Summary: While Smith agrees children have unique interests, he argues they shouldn't vote because they lack the maturity and complex understanding required for such a responsibility.

Conclusion: Children should not be given the responsibility of voting.

Reasoning: Children have overly simplistic views of issues and different time horizons than adults, making them unsuited for the responsibilities of voting.

Analysis: Smith's argument functions as a counter-point to Rossi by introducing a new requirement for voting: intellectual and temporal maturity. While Rossi focuses on 'interests,' Smith focuses on 'capacity.' To find what these statements most strongly support, look for an answer that suggests representation of interests is not the only factor that determines who should vote. Smith's points about 'simple conceptions' and 'time horizons' suggest that a certain level of cognitive development is a prerequisite for participating in the democratic process, potentially outweighing the need for direct representation.
