Final answer:
The biggest city in North America is b) Mexico City, surpassing even New York City in population. New York City, as the largest city in the United States, has historical significance for its transportation advantages that spurred its growth.
Step-by-step explanation:
The biggest city in North America is b) Mexico City. Historically, Tenochtitlan, the precursor to Mexico City, was the largest city in the Americas, surpassing other cities with its advanced planning, infrastructure, and large population. Today, Mexico City is one of the most populous cities globally, and in terms of the urban hierarchy, it is more populous than New York City, reflecting the impact of globalization and urbanization.
The urban landscape of North America has evolved, and with New York forming the economic heart alongside other major cities, they all are a testament to the advancements in transportation, communication, and business operations that have made these cities attractive to people seeking opportunities.
New York City, on the other hand, is the largest city in the United States and has experienced tremendous growth over time due to its advantageous transportation links, including the Hudson River and the Erie Canal, leading to a vast economic advantage. The Northeastern United States, particularly the megalopolis ranging from Washington, D.C. to Boston, is known for its high population density, with New York City anchoring this core region.
