What is your personal moral system? ( code of ethics)

I for my ethics class have to write a paper on the above question, but, im simply not getting it… I dont understand, if what she means that my personal moral system, is stuff, as drinking age of 21 should be lowered, and abortion shouldnt be allowed… Is it that kind of stuff, or what do you believe she means by this questions. Im confused as to what im exactly supposed to be talking about.
