This is a citizen's legal obligation to serve as a part of the body that determines the guilt or innocence of a person accused of a crime

Explanation:

I think you are defining a jury. Juries in the United States are usually between 6 and 12 people. As a citizen when asked and picked, you must serve on a jury unless there is some medical reason why you can't.

I'm thinking of a woman I know who could get up a flight of stairs in a court house. She was excused immediately.

where is the section with the question?

- "the past is made of multitudinous items ranging from anything that can be collected, recollected or assessed to originate in the past. as such, the past is a gallimaufry of particulars that may not have been related in any way. however, the human mind seeks organization to understand concepts and other things. the human mind therefore seeks relationships in explaining and studying the past. history being a humanity, dictates that historians have to serve this human trait by bringing structure to details of the past. historians do this by creating interpretive frameworks that capture as many details as possible."
