We never say in English "the pot stands on the table", but rather "the pot is on the table", or "the pot is placed on the table".
Agreed. I would say sits, not stands.
Agreed. In my mind objects only 'stand' on things when you are speaking in a reverent tone that borders on treating them as humans or animals, such as "The statue stands facing the war memorial." Otherwise they sit.
Duolingo excepts "is" in place of "stands".
Also what the heck is a trivet aha i think
A trivet is a small mat which is placed under a hot pot in order to protect the underlying surface of, for example, a table.
Looks like it may also be made of metal
