An Ethical Quandry
You're taking an "ethics exam".
You know the "right answer" to one of the questions, namely the answer the instructor expects to be given as the correct answer. But, you disagree with the answer as being subtly flawed, and think the correct answer is slightly different.
You are fairly sure the instructor will downgrade your answer if it deviates from the "right" model answer.
Which is the more ethical thing to do: give the answe expected, or the answer you think is correct?
