I have never seen that on any test, nor have i ever seen a question like that.
It was just an example. Not every answer is set in stone, but rather there are a variety of different opinions and viewpoints. If you hold one of these, you must suppress it and conform in order to get the answer right.
The thing is that it was a very poor example. The only time multiple choice questions are used is when there is a definite answer, like who delivered the Gettysburg address, what is the square root of 64, find the preposition in the following sentence. They never have an open ended question like that in a multiple choice test, at least i've never seen one in my time at school. Hell at my college none of the professors ever use multiple choice tests.
A better example would be "approximately how many jews died during the holocaust" and then the answer would be 6 million or whatever the figure is, i don't know it off the top of my head. That is the type of question you would see on a multiple choice test, not the open ended and false question you put forth. Your logic is flawed.
To say that students are not free thinking simply because they will answer a question that has a definite answer makes no sense. Just because you question one generally accepted theory does not make you free thinking, thinking like how i mentioned earlier, where you question theories and try to prove them wrong does. You're not as elite as you think.
