Task: Question Answering
Input (English): Passage: I had spilled some soda on my bed , so I had to change my sheets before I went to bed . First I took off my blanket , which was still clean . I set it to the side . I took the old sheets off , removed the pillow cases from my pillows , and tossed them into a pile on the floor of my bedroom before going to the hallway closet and taking out a fresh , clean set of sheets . I unfolded the fitted sheet first and started in one corner of the mattress , getting that corner in place before stretching the sheet slowly to slip over the next corner , then the next , and then the fourth and final corner . I tucked the bottom end in under the mattress , making sure that I still had enough on the bed to use at night . Then I slipped clean pillowcases onto my pillows . I pulled the top sheet tight and straightened it out over the bed before setting the blanket on top . I was done ! Question: What did they unfold Option1: Pillow cases Option2: Fitted Sheet
Output (English): Fitted Sheet
