The u. s. government gave 130 million acres of land to what industry in the nineteenth century?

Railroad companies

Explanation:

The government gave this large expanse of land to railroad companies. At that time, transportation within the country was difficult, and this led to the West being extremely isolated from the rest of the country. The strategy to solve this was the building of a transcontinental railroad. However, in order to achieve this, land was required. Therefore, the government decided to give 130 million acres of land to railroad companies in order to fulfill this project.

when studying cause and effect, historians usually group the causes into different categories. for example, cultural causes reflect how a society’s literature and art convey the way the society saw itself in relation to the rest of the world. another resource that historians use to understand society is pop culture, which tells them the trends and ideas that are preferred by the common people. when studying cause and effect, it’s important to remember multiple causation, or the idea that an effect could have several causes and vice versa.  

the correct option is “cultural causes” since art and literature are related to the culture of a place. culture is determined by literature, art, music.

the correct option is “pop culture” since it reflects the likes and ideas of common people whereas the rest of the options do not focus on common people.  

the correct option is “multiple causation” since it refers to the idea that events are caused by multiple reasons, not just a single one.
