These short essays will be one page, double-spaced, with a title. An analysis is required; summaries will earn poor grades.
An analysis does not simply repeat what someone else has said better. Your voice should be in your paper. Instead of just saying what your sources have already said, you should be making your own points.
You should attempt to use the facts everyone knows to be true to prove something people may not know is true. The facts everyone knows are summary. The point you are making is analysis.
