Godfrey yes as to question 5, Episode two, I can see how that one is not so easy. I think that Elayne helps stress in that episode how the issue with Agamemnon's example is not "all child sacrifice is offensive" because that would be an absolute bright line that would imply an absolute morality. The issue is much more: "child sacrifice offends our feelings at least in most cases." That focuses on feeling as the root of Epicurean morality and gives us an emotional example that no matter how strong our feelings are in a particular situation, that never crosses over into a bright line that "all killing of children at all times for all reasons by all people in all places" is intrinsically "bad" or "evil."
And that is a huge point to be made and drilled in for a proper understanding of Epicurean ethics.
I can see that that one is difficult, especially given the way I wrote the option regarding Agamemnon. That's an example of how I will need to weigh and balance the purpose of the quiz and how easy we want scoring to be. I'll definitely mark that one as one to consider as we move forward.
