Explanation: The vocabulary and sentence structure are better put together and more advanced.
The answer is C. A musical argument appeals almost entirely to the listener's emotions and if this isn't the right answer my other option would be D.
The alliteration is that she's telling you how her life was and how some days it was good and other days it wan't so good. She uses alliteration because she wants her reader to know how days were during her life. Although she wasn't a slave she still had a hard life and the alliteration she uses represents that and how she wishes things were easier and she's saying that life was hard for folks back then. I hope this helps.
