However, this is in stark contradiction to what the professor told them (that there would be a test at some point next week). Also, the professor told them that he would cancel the test if the students were able to guess what day it would be on; however, they did not do this. They deduced that the test could not be on any day, and as such, did not expect it on any day. The professor could then easily schedule the test for any day (even Friday) and it would be a surprise.
So I got that much of it right.
This was pretty easy actually. I knew that just by thinking that the quiz would be cancelled, it can be given to them on any day since it's a surprise quiz.
