I call it bullshit. I just asked that question to a seminar of paedagogic students, without a single person with physics background. 2 Choose answer the first answer, 3 the sencond one, the other 20 choose the correct answer. I expect much better results for students with physics background.
/edit, well bullshit is a bit strong, but replication failed
