* slight nitpick. I changed the basis of the question to encompass the need to reassess driving style in the presence of a change in weather conditions, as opposed to choosing specific instances of danger. That is not a rephrasing as I originally contended. My apologies. If all roads can be precarious, the answer is all of the above, thus solving the dilema of the test taker understanding the need to be more perceptive in colder weather. We cannot control for all variables that would make a road slick or dangerous, and therefore cannot test them all individually, but must group them together into a situation (ex: road conditions changed). If we accept that driving in and of itself is an active activity, then we should not have to distinguish between specific changes in road conditions for any change in road conditions should be enough for the driver to reevaluate their driving. This question on the test should then be changed completely to reflect the fact that a change in road conditions necessitates a reevaluation of driving style. I would further contend that "hidden questions", such as the one described, test one's ability to take multiple choice tests. If I know A and B, I have no need for C and there is no need for me to even look at it. In fact, if there were 40 options, "All of the Above" still has to be the correct answer, even if I have no clue what the other 37 options are. Teaching is not the intent of a test. Unless, of course, we are assuming that the test taker did not learn anything before taking the test; In which case the intent is not testing them at all but ensuring that they have some basic skills to get by. However I agree with your intent, the creation of questions for a test is not a trivial pursuit.
