Answer:
Steel, oil, and agriculture businesses all benefited from the growth of railroads.
Explanation:
Because of railroads steel, oil, and agriculture became easier accessible resources.
Steel also contributed to the growth of railroads. The railroads were the biggest customers for the steel industry because thousands of miles of steel track were laid. In turn, the railroads had a great impact on the steel industry. To supply their biggest customers, steel producers developed cheap, efficient methods for the mass production of steel rails.
The railroad companies contributed to the development of the West by selling low-cost parcels of their western land for farming. Oil companies grew swiftly in this period, most notably the Standard Oil Company, founded by John D. Rockefeller.
Lastly, agriculture the railroads played an important part in agriculture by moving the goods to markets both within and outside of the state. Most of the dairy products were shipped to California, and the wheat was shipped either as grain or as flour to California and the southern states
The main results of the Spanish American War was a protectorate over Cuba, annexation of Puerto Rico, and increased US influence in the Philippines.
The main idea of "The Negro Speaks of Rivers" is the long history of the black race. This theme can be identified when the speaker in the poem mentions that he has a connection or something that links him to some great rivers. He's trying to explain that, like the rivers that have seen many civilizations grow and flourish, he has also grown and flourish with the rivers.
The speaker mentions four rivers:
- The Euphrates
- The Congo
- The Nile
- The Mississippi
All of these rivers reference different civilizations, and the speaker tries to link the last river he mentions - the Mississippi- to the history of slavery.
So, we can definitely see how the history of the black race is the main idea in this poem, written to explain that, like rivers, the black race has existed as long as history goes, and it has seen civilizations thrive and expand just like rivers.
