Why might the electoral college issue threaten to become a partisan
one?

Because the electoral college has certain dynamics that tend to favor one party over the other.

For example, the electoral college slightly favors rural states, and since rural states tend to vote Republican, the Republican party is usually more vocal in their defense of the electoral college than the democratic party.

The Democratic Party is largely the opposite. Favored in major cities and the most populous states, they are more likely to be against the electoral college because of this.

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.
