Does this help?

Lodged in my inbox today was an email from a professor that was sent to everyone in my class, in which she responded to two student questions asking for a point of clarification before a quiz on two readings we did for class. Anticipating something useful, I read through the questions and responses. Note my careful word choice here: I used "responses", not "answers". And with just cause. Her response to both questions was, essentially, "read the material and make sure you can answer the questions in your own words." Seriously, that's all you can give us? Advise us to read the material again?
