Which statement gives the clearest accurate account of Upstate Networks?

• Auburn and Rochester connect national abolitionist figures with local institutions and communication networks in upstate New York.
• A state-level density statistic obscures strong spatial heterogeneity between New York City’s urban core, suburban belts, regional cities, agricultural counties, and Adirondack wilderness.
• Saratoga’s importance is partly diplomatic because battlefield success affected French calculations about intervention.
• Primary-source preference does not eliminate the need to understand definitions, because Census, BEA, BLS, USDA, and state agencies measure different concepts.
