Hey everyone above! Instead of quoting you all I'm just addressing it here.
I don't know the wording of the exact question you are talking about, but I think what it appears happened to you is what happened to me in my trial. My short answer question was something like, describe the core ethical teachings of the religion. So I launched into that, and immediately jumped to the sexual or bioethics (can't remember if I did Christianity or Islam for this bit). So my response was like: The ethical teachings of Christianity regarding bioethics are say no to abortion, in some cases yes to euthanasia, because ultimately this is God's plan (OBVIOUSLY THIS IS A SIMPLIFIED VERSION). It was only 5 marks or less, and I thought I'd put some super specific details in there and I'd be getting a hell yeah from my marker. I only got like, 1, possibly 2, marks? Because I'd more or less mentioned that creatures are made in the image of God and referenced it - which is the kind of ethical teaching they are looking for. So they weren't asking me to apply the ethical teachings to anything, which I did by relating specifically to bioethics, but instead they asked about the teachings ~in general~ of the religion. You can skew these towards your set of ethics, whether that's environmental, ethical, or bio, but unless the question is asking about adherents using the ethics to make decisions, or application of ethics in modern society, then you should be sticking to the teachings individually.
The way I organised my notes after trials was like:
-Core ethical teachings
-Sources of ethical teachings
-Applications of ethical teachings
So this kind of three-tiered level of studying helped me draw everything apart. I'm not sure about how you all learned this in the classroom, but for me it was almost like learning the ethics through the cases of ethical issues. Which can be great, but it meant I didn't know how to talk about anything individually, which put me in a bad position for the short answers.
Does this clear anything up for anyone, or else, raise new issues? I try to cover this in my lectures because I know it's confusing, but often it doesn't make sense until you actually do an exam where it asks you to specifically divide things.
