Step-by-step explanation:
The question 'Which city served as the base for British operations for most of the war?' refers to historical events, and the correct answer is B. New York. During the American Revolutionary War, British forces used New York City as a major base of operations after it was captured in 1776.

In the context of 'Which city was rebuilt by Baron Haussmann in the second half of the nineteenth century?', the answer is d. Paris. Baron Haussmann was responsible for the massive urban renewal program of Paris, which included the creation of wide avenues, parks, and other city improvements that transformed Paris into the city as it is known today.
Discussing global cities, it's important to highlight their role in today's global economy. Cities like Nairobi, Dar es Salaam, Addis Ababa, and Lagos exemplify how urban areas can become key economic centers due to their business activities, infrastructure, and globalization influences, providing significant employment opportunities and supporting large populations, exceeding the size of some major American cities.
