I guessed and got the question right just by using common sense without looking anything up in BOL.

The only complaint I have is that it should be worth more than 1 point because it's a multiple selection question and those are always harder to guess correctly.

If you were to completely guess a question with 5 radio buttons, the probability of you getting it correct is 20%. If you have 5 check boxes instead, the probability is 50%^5 or 3.125%. Or, thinking about it a different way, there are 32 separate combinations of answering that question so the chances are 1/32 or 3.125%.
