Universal ethics can us a. understand ourselves b. understand our culture c. interpret others' non-verbal communication d. make ethical decisions

The answer is D. make ethical decisions.

Explanation:

Universal ethics has a premise that, if something is bad in one place or for one person, it is bad everywhere and for everybody. That means there are behaviors that are universally accepted and others that are universally condemned. Such understanding help us make ethical decisions even when in unusual circumstances, or when we do not have a palpable guideline to follow. An extreme example would be killing and stealing. Even though we have so many different cultures around the world, those two actions are considered abominable everywhere. As we can tell, if something ends up harming someone, it means it is most likely unethical. There might be some exceptions - self-defense, for example -, but those happen under very specific conditions.
