Philosopher: An action is morally right if it would be reasonably expected to increase the aggregate well-being of the people affected by it. An action is morally wrong if and only if it would be reasonably expected to reduce the aggregate wellbeing of the people affected by it. Thus, actions that would be reasonably expected to leave unchanged the aggregate well-being of the people affected by them are also right. The philosopher's conclusion follows logically if which one of the following is assumed? ['There are actions that would be reasonably expected to leave unchanged the aggregate well-being of the people affected by them.', 'Any action that is not morally wrong is morally right.', 'Only right actions have good consequences.', 'Only wrong actions would be reasonably expected to reduce the aggregate well-being of the people affected by them.']
