The problem is that the image, by it's very nature is original research. The student, who, by the way, did a very good job, has built that image by pulling together a bunch of different sources, combining them, and presenting a single ""final"" product. On Wikipedia, we classify that as original research, which we don't allow. As someone who has in the past taught both high school and college myself, I know that it's actually an odd thing to find out that basically any research paper that a student would write for a typical college level class, as well as a good number of high school papers, would be considered original research under Wikipedia rules. Now, it could be possible to include each of the points individually expressed in the image within the text itself, though we'd have to measure other issues (like how relevant each point is to the larger topic). But anytime we draw a conclusion by synthesizing information from multiple sources, we're in danger of violating WP:OR. I hope this helps; let me know if you or the student have further questions.   "
