Final answer:
The terms 'folkways' and 'mores' are used to differentiate between minor social norms and significant moral norms; the former guide everyday behavior without moral underpinnings, while the latter represent societal values with potential for serious consequences if violated.
Step-by-step explanation:
The terms used to differentiate between right and wrong and polite and rude are moles and folkways. Mores are norms that embody the moral views and principles of a group, which when violated can lead to serious consequences, potentially affecting one's standing within a community or society at large. Examples of violating mores include acts like plagiarism in an academic setting, which can result in expulsion. On the other hand, folkways are norms that direct day-to-day cultural practices without moral implications, such as dress codes or greeting behaviors, and are not associated with serious sanctions. Therefore, the correct answer to differentiate between right and wrong and polite and rude is: 3) Folkways; mores.
