Manhattan seems to sprout shiny new skyscrapers an easily as a garden grows weeds, but despite the modern appearance of the concrete jungle at the heart of New York City every engineer knows that before breaking ground, they need to step back in time, with the help of Viele’s map. 1865, Egert Viele, a cull engineer and Chill War veteran who surveyed the land for Central Park and later served in Congress, published a map that is still crucial almost 160 years later. His map showed all the original marshes and waterways of Manhattan Even today, engineers rely on his work to determine still conditions and any underground water that sows through a building site, potentially undermining foundations. Which of the following additional resources would validate the information given in Viele's map?
A. A map of the New York City transit system
B. A map of the wetlands on Manhattan land used to observe migratory birds
C. A map showing population density of New York City by borough in 1865 and 1965
D. A map of Civil War battle sites in and around Manhattan
C. To validate the information given in Viele's map, a relevant additional resource would be: "A map showing population density of New York City by borough in 1865 and 1965." This resource could help confirm the impact of Viele's map on urban development and changes in the city's layout over time.
Therefore, the Correct Answer is C.
