Well it obviously depends on the question, but one I got today gave a scenario where a software developer had made a program but hadnt added security, and his employer wanted to launch it right then for his online customer base, it asked what the dilemma the programmer was facing was, and I answered:
On one hand, ___ could agree to (launch the software like his boss told him to do) but this would (jeopardise the integrity of data processed by the solution, putting its users at risk and potentially violating the Privacy Act)
On the other hand, ___ could disagree and (refuse to launch the software until security measures were added) but this would (put his employment at risk since his employer demanded the solution be launched straight away)
The stuff in brackets is what you would replace with the relevant stuff from whatever scenario they gave you, I think the focus on ethics questions isn't about laws or resolution, it has a focus on identifying the DILEMMA (dilemma means decision between two non-preferable options) And by identifying these options in an 'on one hand/on the other hand' framework you're making it really clear that you know what the two alternatives are, why they are ethically non-preferable and who is involved.
As I said before, depends on the question, don't just copypaste this wherever you see the word ethics, but I think it's the emphasis of most ethics questions, especially if they ask about the dilemma specifically. If it doesnt seem to be asking about a dilemma, I think you have all that is needed anyway; explaining what is wrong, why and who it effects.
