Answer and Explanation:
The situation described is a formal social interaction. Formal situations usually involve certain rituals, so to speak, or certain rules of behavior. People are expected to dress a certain way, to talk to each other politely, and to have manners at the table. Regarding table manners, formal situations demand a bit more knowledge and etiquette, since different types of silverware and glasses are likely to be used. Therefore, knowing proper table manners helps avoid difficult or potentially embarrassing moments. Others attending the same event are likely to have learned etiquette as well, so it is best to learn in advance and behave appropriately to prevent becoming the center of attention for not knowing which fork to use or for slurping the soup, for instance.
