I once devised a test for new employees that was MC. There were four answers to choose from and all of them were right.

After the test I announced that everyone had passed and revealed that the point of the exercise was to prove that there is no right answer to many of the problems we faced. Therefore you must pick the most accurate course of action based on the facts at hand as that was your job.

Every decision can be second guessed, but not taking action on a problem was never acceptable.
