Man... tomorrow you will have a 666-day streak! You are the God, or should I say, the Devil himself! ;)
"Czy sprzedajesz jego kota?" = "Are you selling his cat?"
"Sprzedajesz jego kota?" = "You are selling his cat?" / "Are you selling his cat?"
So techincally, both are correct in this sentence, aren't they?
Theres something peculiar about this sentence.. if only I could pin point the oddity.
I wrote "you sell his cat" and it was marked as wrong, is there a reason for this?
Okay, if the default English question had a declarative word order, I guess this one's correct as well. Added.
Although I think it (You are selling his cat?) shouldn't be the default one. I'll make it just an accepted one and go with a normal question for the main option.
