Why are moral or ethical questions NOT testable? A. They are questions that are impossible to answer. B. They are better answere
Radda [10]

Answer:

<u>C. The answers depend on people's opinions, not on observations.</u>

Explanation:

Morals are what people <em>think</em> is the right or wrong behavior and the <em>goodness</em> or <em>badness</em> of a character.

Ethics are <em><u>morals</u></em> that <em><u>govern</u></em> a person.

So the answer is C because these answers cannot be seen from the outside.

For example: A PERSONALITY TRAIT is something you can't really see. A PHYSICAL TRAIT is something you <em>can</em> see.

Ethics and morals are like personality traits.
