Answer:
a)the Erie canal
Explanation:
From the provided information in the question, it is "the Erie Canal" that fits that information perfectly. As Erie Canal is a Milestone in U.S. Transportation, with a 363 miles long. The construction started in 1817 and got completed in 1825.
It connected the Great Lakes region with the Atlantic coast and improved transportation into the interior of the United States.
It also lowered the cost of transporting goods by ninety percent
It also made New York more populous and became the urban Empire State.
Athens depended on trading.
If they did not trade, their economy would fall apart.
Athens traded things like ships, coins, art (pottery), food and metals like iron and silver.
The argument is that the mortality transition occurs exogenously and is the cause of a subsequent decline in fertility and rise in urbanization. This exogenous demographic process plays out over time, and has effects on economic, social, and political development. Hope this helps. :)
