These are the three that have to do with social matters, and thus historians' answers would be influenced by their social ideology:
- 2 )How did the Harlem Renaissance affect American culture as a whole during the 1920s?
- 3) How did desegregation affect the white and black populations of Alabama?
- 6) How did religious intolerance impact different groups of immigrants in early America?
As for the other answers:
- 1) has to do with politics/government or political science. (How were colonial constitutions in America different from British colonial charters?)
- 4) has to do with diplomatic history / international relations. (What was the diplomatic relationship between the United States and the USSR after World War II ended?)
- 5) has to do with military history. (What weapons were most effective in World War I combat?)
The three items I noted at first all concern social/cultural topics, and so would be influenced by a historian's own social ideology.
