Wolf – You are right that, that is one of the differences between a rishon and achron, and that girls might know, because they learn *historiya*. But what I was reffering to was, that they dont know the mailah of a rishon over a achron, they don’t know that you are midayek in what the ritvah or rashbas words, and you are not midayek in how some hintege achron worded his sefer.
