Explanation:

The Answer is...  D) The Knights of Labor included African Americans, but the American Federation of Labor excluded them.

The Knights of Labor accepted workers of all skill levels and sexes which automatically means A, B and C are wrong. We know that blacks were included after 1883. Therefore we can come to the conclusion that since The Knights of Labor included all skill levels, sexes and color then D is the only possible answer.
