Passage Summary: Every immoral act makes the person feel guilty. Additionally, if an immoral act happens in public, it is guaranteed to offend people.

Reasoning: All immoral actions result in feelings of guilt, and if those actions are done in public, they also offend public sensibilities.

Analysis: This is a 'Must be False' question, so we are looking for a statement that directly contradicts the rules established in the stimulus. The stimulus provides two conditional requirements for immoral acts: they always involve guilt, and if they are public, they always offend. To find the answer that must be false, look for a scenario where an immoral act occurs but one of these conditions is missing—for example, an immoral act where the person feels no guilt, or a public immoral act that fails to offend anyone. Any choice that describes a 'guilt-free' immoral act is a logical impossibility based on these premises.
