What is the article about? Insert the article, perhaps. To determine the purpose, make sure you check what the author is trying to get out of telling their certain audience. Are they trying to persuade someone? Inform? Entertain? Provoke emotions into the reader?
As far as I'm concerned, the reason is usually to inform the reader of a certain subject or invoke certain emotions in the reader. However, you included no paragraph, so I can only guess.
