Valikhan, I strongly disagree with you. Yes, of course, we can understand the causes with the help of dictionaries if some words are unfamiliar for us. But I don't consider the article which just lists the main points as a perfect job. She should have devoted her article to the causes and doubtlessly, should have explained how the listed causes can result in the teenage suicide since the main indicator of the content meaning of the article,  is its title, which says about "CAUSES".
Also, the causes listed in the article can be understood in a number of ways. Because every reader has his own and different view on things. The author should have defined them based on her own outlook, clarifying them in his own way of thinking.
