@VANESSAHERNANDEZ i just realized i made that same mistake

I chose D, and the explanation says that we dont know who bought the books, and that it could be beginners buying advanced cookbooks. But doesn't the question stem say "more cookbooks than ever were purchased by professional cooks"?

But how is the first one even a conditional statement, or are we not worrying about that right now and just looking for indicator words?

should we be taking notes on this??
