Prior to becoming a civil rights activist and politician, John Lewis wanted to be a preacher.

Explanation:

John Lewis was a civil rights activist, congressman, and a prominent leader of the Civil rights era. He was also a "Freedom Rider" and led the "Bloody Sunday" march.

Ever since he was a child, John Lewis wanted to be a preacher. He would imitate preaching and  by the age of 5, he preached in front of their chickens. His first experience preaching in front of people was at the age of 15. Despite living during the racial discrimination period, he hardly had any exposure to such racism until he listened and became inspired by the sermons of Martin Luther King.

He would later become so involved in the racism issue and would take part in many of the demonstrations and protests of his people, the black people.  Attending a theological institute helped him learn more about non-violent protests, but also led to many of his arrests for his involvement in many demonstrations.

he believed that congress would be better not dealing with "lobbyists", or people who seek to influence (a politician or public official) on an issue, since historically, they had problems with these kinds of people. he thought lobbying produces benefits, but should be carefully monitored.

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.
