I think you didn't read B correctly...
The correct answer is A. The transcontinental railroad.
To determine the correct answer, you can analyze each option and eliminate the choices that are incorrect.
Option A - The transcontinental railroad: The construction of the transcontinental railroad in the 1800s played a significant role in opening up the western United States to immigration and business. It connected the eastern and western coasts, making it easier for people to travel and settle in the western territories.
Option B - The underground railroad: The underground railroad refers to a network of secret routes and safe houses used by enslaved African Americans to escape to free states or Canada during the 19th century. Although it played a crucial role in helping slaves to freedom, it did not directly contribute to the opening up of the western United States.
Option C - Route 66: Route 66 is a famous highway that extended from Chicago, Illinois, to Santa Monica, California. However, it was not built until 1926, which makes it an incorrect choice for the 1800s timeframe.
Option D - Cattle farming: While cattle farming did play a significant role in the western United States during the 1800s, it did not directly open up the region to immigration and business like the transcontinental railroad did.
By examining the options, we can conclude that the correct answer is A. The transcontinental railroad.
