Preposition case with adjective Здравствуйте So I am doing my home work right now but found many words that make me so confused. These questions in this exercise are about preposition case. I understand the form and also many adjective and how they change after о/на/в. But I don't know how to change the adjectives in these questions. 1. На какой улице? I should answer the question with (Пушкинская). Should I answer like this? На Пушкинской улица. 2. В каком факультете? (исторический) should I answer like this на историческем факультете. Because I don't know how to change those two adjective. And I thought the adjective in Russian only большой, красивый, etc. Why Пушкинская and исторический are adjectives? Спасибо
