Deanchhsw - Sorry if my question wasn't clear. I was asking about the strength of my subjects; I wasn't sure which one would appeal more to Amherst, but I wound up writing it based on option 2. Thanks for your reponse
NBZ - This response is really late, so you've probably already written your supplemental essay, but yeah, I'd say that the admissions office doesn't expect you to adhere too closely to the quote. Just use it as a jumping off point. (I went with option 2)
Lemonjello - Thanks. That's what I thought too.
