Answer:
Railroad
Explanation:
The Union Pacific railroad, which began in Omaha, Nebraska, was mostly laid down
by ex-soldiers and Irish immigrants. The Central Pacific, which started in
Sacramento, California, was worked largely by Chinese immigrants.
The government paid the railroad for each mile of track, so companies got more money
for longer, less direct routes. In addition, longer, winding routes reached more towns.
The railroad company received even more money from the towns it reached.
Cattle drives went through many cities, starting with St. Louis, Kansas City, and
Sedalia, Missouri. Next, they included Abilene, Kansas; Cheyenne, Wyoming; and
Dodge City, Kansas.
It also made coal and iron more profitable.
