"You do not like this soup?"
Translation:Nie lubisz tej zupy?
It doesn't sound wrong on its own, but it's in the nominative case, so it can't be used in this sentence. This sentence requires genitive.
"zupa" is feminine, so "ta" in Nominative. "lubić" takes Accusative: "tę". negated Accusative turns into Genitive: "tej".
