Compare: Similarly both of the articles talk about the same thing and have a lot of the same reasons,points, and captions.
Contrast: On the other hand they also have lots of differences. The first passage (Show Down in Selma) talks a lot about John Lewis and has a lot of main points and details. it also can be compared to a report other than a article as well as it being a secondary source as the author was not there to see the event. The second passage (Marching from Selma to Montgomery in 1965) it talks about the people in Selma but not much about John Lewis. Also the article is more a primary source than a secondary as the author, Andrew Kopkind was part of the march. in addition it covers more smaller details.
