Task: Question Answering
Input (English): Passage: This morning I woke up and all the covers were off my bed . Even though I do n't normally make up my bed , this morning it was necessary . I decided to change my sheets , since they were off anyway . I placed the comforter on the side . I gathered up the sheets and pillow cases and brought them to the laundry . Next , I got out another set of clean sheets . I stretched the sheet over each corner , making a nice tight area . Next , I put the flat sheet on , tucking in the bottom and the sides . Next , I replaced the comforter , being sure that all the sides were hanging over the same amount . Now , my bed was beautifully made with clean sheets ! Question: In addition to the sheets, what else was removed? Option1: pillow cases Option2: the mattress
Output (English): pillow cases
