American business interests needed to be protected

Explanation:

The intervention of the United States in Nicaragua was mostly because of economic interests. The us wanted to have full control of the small Central American nation as it was located in a place that had the potential to be both of great benefit for the United States, but also to create a lot fo economic damage. One of those economic reasons was the planned canal in Nicaragua, that was going to compete with the one in Panama. Having the Panama canal under their control, the US didn't wanted another one that was going to compete with it and take away large portion of the money that they had secured with it.

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.
