Thanks Tom,

I have to agree with your assessment. I would have expected the name, data type and null-ability to all be >95%.

I actually felt that this question was so easy, that I asked Steve to not show the number of correct answers... if it showed 3, I felt that everyone would just check those 3. (My thinking was that they would apply deductive reasoning, instead of thinking about the question. I wanted more thought to go into it.)
