Necesito Separar los adjetivos positivo, comparativo y superlativo del siguiente texto. Yesterday, my sister and i went shopping. We wanted to buy something nice for our young brother so we went to the new mall . What at surprise! It was bigger than the old too one. It had larger department stores. It also had a great place to eat different kinds of food. It had the most amazing garden of all the malls in town. We went into several stores looking for something we could buy but everything was too expensive. We couldn't afford it so we decided to go back to our old city mall.
