Which statement is the best-supported description of New York’s Erie Canal Costs?

• The Erie Canal converted a favorable natural corridor into lower-cost transport infrastructure, reducing friction between Atlantic and interior markets.
• The 1848 Seneca Falls convention is best understood as a landmark in organized women’s rights activism rather than the beginning of all advocacy for women’s rights.
• New York’s near-flat 2024-2025 population estimate should not be generalized into a long-term trend without examining a longer same-vintage series.
• Current-dollar GDP measures production at prevailing prices and therefore combines quantity and price effects.
