If Mrs. Williams asked me whether the Buddhist Ethics test is a valid way to decide if an action is right or wrong, I could explain that:
a. Everyone depends on and benefits from aspects of the common good, so if I or my organization benefit from the common good I should contribute to and not damage the common good.
b. Since everyone is equal as a person, an action that is right for one person is right for all others in similar situations.
c. The Buddha, whose followers gave him the name "The Enlightened One," gave us his insights into the true nature of the world.
d. Society is made up mostly of ethical people, so right and wrong are usually indicated by what other informed members of the society judge to be right or wrong.
