I give the first story an excellent grade.
You got the Who, What, When, and Where just fine. You did, however, skimp a bit on the Why. This is understandable.
When you beard the dragon in its den, it is not prudent to linger overlong.
Still, an eighty percent is very good, especially considering the very lax performance of your competition. If the grade is on the curve, you have pushed the envelope in the right direction.
That is for the next article. Its a little more hum... well a little more of everything I hope!
