Greg is in the library just hours before the exam. He notices some of the other students from his class huddled around one of the tables and joins them; he discovers that they are talking to a young man who has somehow obtained a copy of the exam from the instructor’s private files. It seems apparent that this could be an opportunity to do well on the test in spite of his lack of opportunity to study. Greg reasons "I cannot cheat. If everyone cheated in every situation this would be a sad world." Which philosophy best depicts Greg's reasoning:1. Egoism
2. Act Utility
3. Rule Utility
4. Kantian Ethics
