About to get a B

To it sounds like you did not interpret the question correctly. All writing questions contain two dimensions: breadth and depth. The breadth of this question was given to you as five features. Depth was given as 1-2 sentences. So I would have written 1-2 sentences on each of the five features. You only wrote on two features. I may not be totally in sync with your prof., but my academic experience it's best to always write more if in doubt of what is being asked.
