I did not see any sources attached to your question, so I will explain how to determine whether a source is primary or secondary. You have categorized your question under "Literature," so I assume you are writing a literary analysis. For a literary analysis, the literary work you are analyzing, whether it is a poem, short story, play, or novel, is the primary source. In your analysis, you will be quoting from, summarizing, and paraphrasing the piece of literature you are analyzing. Whenever you refer to the work itself, you are using a primary source.
Anything that has been written by others about the primary source you are analyzing is a secondary source. That could be an article of literary criticism in a literary magazine, a source that gives biographical information about the author of the work, or a history textbook that helps you understand the time period that the work was written in or is set in. The articles and answers to homework questions that you find here on eNotes are secondary sources. You should always check with your teacher to find out what types of sources he or she will accept for an analysis. Different teachers and different assignments will require varying levels of documentation. A secondary source is not always reliable; other criteria are involved in evaluating secondary sources. The term "secondary" only reflects that it is one step removed from the primary source; it does not evaluate the quality of the source.
