Nice to see a question about a new feature in sql 2012.I took a guess as to what the code was intended to be, and got it right. But there are ambiguities here which we have to resolve by pure guesswork, and maybe the low success rate is the result of this. The current success rate is 23%, and the expected result of chosing one at random from each mutually contradictory pair is 25%, which indicates either no knowledge at all in the respondents (which I don't believe) or enough ambiguity in the question to have much the same effect as if answers had been random.
It would be interesting to find out what percentage got the answer right according the stated question.
Curently 57% selected option 2, but it's not clear how many of those also selected option 3. The upper bound could be calculated as the percentage that selected option 3 - the percentage that got the answer "offcially correct". I.e. 58 - 23 = 35%.
Of course there are those who figured out the intent of the question and answered "correctly". So it's quite possible that as many as 50% did undertsand the issues the question was supposed to test.
