New Technology Leads to Bigger Cities
In the 1800s, the United States was still a very young nation, trying to solidify its identity. The Industrial Revolution began in Great Britain, a fast
development of society following the introduction of machines. The United States was slower than Great Britain to fully embrace the changes.
Yet key technological developments caused a rapid growth in American urban areas.
Better farming methods and tools in the 1800s increased food production. Americans were able to grow enough food for their families as well
as to sell. The abundance caused food prices to fall.
The expansion of cotton and the growth of textile factories in northern states helped produce the first wave of American industry. More people
turned to work in northern factories as a way to support their families. Thousands of immigrants to the United States also settled in or near
port cities, looking for work. Even today, the need for work is a common reason people move to urban areas.
As a result, cities grew in numbers of people and physical space. As more people and businesses moved in, they needed buildings for living and
working. They needed ways to move around the city. We call this process urbanization.
In 1820, the United States had only a few cities of 10,000 residents or more. About seven percent of U.S. residents lived in urban areas. The
number of cities with more than 10,000 people grew quickly over the next 40 years, especially in the Northeast and Midwest. By 1860, about 20
percent lived in cities. Philadelphia and New York City were the most populated cities in 1860 and would soon reach one million residents.
The urbanization of the United States quickened due to technology improvements. Without innovations in food production, the factories could
not have grown so quickly. The trend quickened after 1860 and continued throughout the 21st century as well. By 2007, more Americans lived
in or near cities than they did in rural areas.

Answer 1

"Even today, the need for work is a common reason people move to urban areas."

This sentence, although not inaccurate, is not necessary in order for the rest of the paragraph to be coherent. The sentence states that nowadays, people continue to move for work. However, the passage is not a comparison between the past and the present. It simply wants to inform us of the changes that led to bigger cities. Therefore, you can remove this sentence without seriously altering the author's explanation.
