Knowing leads to a question of conscience, Cornucopia writes on the first page. Well, that's right, that's what ran into. As an economics teacher, I can only confirm what Cornucopia writes, even though it deviates from the teaching and examination material we are working with. How to deal with this? This research has put me in a dilemma. Do I continue with the inaccuracies in the teaching materials or do I tell the truth (which deviates from the knowledge you as a student are expected to reproduce during tests and examinations)?
