I answered the translation of "Is it not your jacket", as "Sie ist nicht deine Jacke".
Duolingo marked this wrong. Am I indeed wrong, or is this an error in the accepted answer?
I know that I have definitely seen "er/sie" used as "it". Are there cases when feminine and masculine nouns are referred to only with es?
I checked this source: https://en.wikibooks.org/wiki/German/Grammar/Pronouns but since it is just a table with generic descriptions, it was unable to explain to me why a native speaker would or would not select a masculine or feminine pronoun for a masculine or feminine object rather than the neuter reference in standard conversation as the equivalent of the word "it" in English.
