Task: Question Answering
Input (English): Last weekend, my friend and I decided it would be a good time to paper our living room. The previous residents of the house we live in had used wallpaper on the living room walls that was a very odd shade of red, which we thought looked strange. We wanted the living room to get a new color of wallpaper, and we wanted to choose a color that would match our personality. We first went to Sherwin-Williams, which is a paint and wallpaper store. We looked at the wallpaper color samples and picked up a few brochures with examples of how the samples would look on our walls. We decided that a cheery yellow color would look best on our walls, and selected that color. We then returned to Sherwin-Williams and purchased the yellow wallpaper. We then applied the wallpaper to our walls and stood back to admire our work. 
Question: Who papered the room?
Output (English): they and their friend did
