The correct answer is: D) The essay needs more supporting facts or examples.
The requirements for a good essay include a strong central argument or purpose, this needs to be developed in a progressive way through the text. It must have a logical order that is shown in the pharagraphs which make the points of your argument, in other words, this pharagraphs must help you support your main idea. Credibility is necessary and it's achieved by using factual, logical and reasonable infortmation.
In this case "more elaboration" means that the central argument is correct and the general structure too but it needs more information to support the arguments. The information given by the student is not strong enough to convince the reader, in this way his point of view can be disqualified very easily. By giving more supporting facts and examples the reader can make sure that the author has knowledge about the subject and will believe or test the ideas.
