Task: Question Answering
Input (English): It was 2 days before my friend Marc's birthday. I had already bought his present, but it still needed to be wrapped. So, I went to Walgreen's, and purchased some wrapping paper. I then came back home and got the gift that I bought for Marc out. I set the gift down next to the wrapping paper. I then opened the wrapping paper, and pulled out enough paper to cover the entire gift. I used a pair of scissors to cut the paper at that length. I then put the paper on the floor, and placed the gift in the center of the paper. I then began to cover the gift with the paper, by folding each side of the paper until it was over the gift, then I would take another side and do the same, until all sides were covering the gift. I then used tape to keep all the folds neatly together. Marc's Gift was now wrapped. 
Question: Why did they use tape?
Output (English): to hold it together
