Final answer:
It is not appropriate to place silverware back on the table once you've finished using it. Rather, it should be set on your plate, either crossed if still eating or together on the right to indicate you're done. This applies to all dining situations.
Step-by-step explanation:
The answer to your question, 'Is it appropriate to place silverware back on the table when you are finished using it?', is B) False.
In proper table manners and etiquette, once the silverware is picked up from the table, it should not be placed back on the table again. Instead, they should be rested on your plate, with the fork and knife crossed if you're still eating, or placed parallel to each other on the right side of the plate to signal that you are finished.
The same rule applies to all types of dining situations, be it a casual or formal event. Replacing silverware back on the table after use is considered unsanitary and is generally not in alignment with good table manners.
