Question

the panama canal railway, completed in 1855, connected the atlantic and pacific oceans across the isthmus of panama. a historian argues that the railway transformed panama from a simple crossing point into an important hub of international commerce.
which quotation from a primary source would best support the historians argument?
choose 1 answer:
a \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.\
b \the journey across panama by railway took approximately three hours, a dramatic improvement over the previous week - long journey by mule and canoe.\
c \by 1860, several trading companies from around the world had established warehouses and offices in the panamanian cities of colón and panama city, creating permanent trading networks that operated year - round.\
d \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.\

Explanation:

Brief Explanations
  • Option A only mentions ships docking briefly, which doesn't strongly support Panama as a long - term international commerce hub.
  • Option B focuses on the time improvement of the railway journey, not on Panama's role as an international commerce hub.
  • Option C shows that by 1860, trading companies from around the world had set up permanent operations (warehouses and offices) in Panamanian cities, creating year - round trading networks. This directly supports the idea that Panama became an important hub of international commerce.
  • Option D is about the railway company's pricing and transportation costs for merchants, which is more about the railway's business model rather than Panama's role as an international commerce hub.

Answer:

C. "By 1860, several trading companies from around the world had established warehouses and offices in the Panamanian cities of Colón and Panama City, creating permanent trading networks that operated year - round."
