Why is 에서 needed on the word farm?
I believe it's to show location
Shouldn't it be 을 as the farm is the object?
에서 is going from a place
에 is going to or being in a place
떠났다 should also be correct
Thus, Duolingo found the pigs!
Snowball is that you? We need you, come back!
How about "the pig left from the farm"? Not correct?
where did it go
