These are from a homework assignment (from my teacher, not a book), which I don't think will count significantly toward my grade. I'm just curious if I got this right. I've been ill and missed some class, and my head's still woozy, so I just want to make sure I'm on-track, or whether I should try again. Thanks! \n" );
