Question

the panama canal railway, established in 1855 connecting the atlantic and pacific oceans across the isthmus of panama. a historian argues that the railway transformed panama into a major trading point and a hub of international commerce. which quotation from a primary source would best support the historians argument? choose 1 answer: ships from around the world would regularly dock at panamas ports to transfer their cargo and passengers to other vessels, though they rarely remained in port for more than a few days at a time. the journey across panama by railway took approximately three hours, a dramatic improvement over the previous week - long journey by mule and canoe. by 1861 several leading companies from around the world had established warehouses and offices in the panamanian cities of colon and panama city, creating permanent trading networks that operated year - round. the railway company maintained consistent pricing for all cargo crossing the isthmus, regardless of the goods origin or destination, which helped establish predictable transportation costs for merchants.
