No it would not be the norm. First you have to believe the student who pointed it out since I doubt anyone else would have known what the question even meant. I knew what it meant and what the answer was. How many times have you seen a question on a test that you had no idea about? Since you have no idea what it is about how would you know that it was never talked about or in the textbook? Here, what is an H1B Visa and the problem with it? No you can not Google it. So in Frank's intro class who would know what an H1B is?
