"I see that woman."
Translation:Widzę tę kobietę.
Something got pretty mixed up with this exercise. Yes, "tamtą" should be the main option and it wasn't accepted at all. "tę" also would work because Polish has ta/ta/tamta while English has this/that/that.
But now, as Incubator only allowed me to go in such a way, the English version will be "I see this woman" and thus Polish version will need "tę".
