Task: Question Answering
Input (English): I was invited for a party, and I had a very nice dress that I decided to wear. But when I saw, it has one button missing. So I had to fix it. That button had 4 holes, so I wanted to fix in such a way that it looks good. So I had to choose exact matching color with my dress. The button was golden. I started to sew it on back side so , the knot will not show up. Then I poke my needle in one of the hole and stretched my thread all the way, then I inserted the needle in to the opposite side of hole. When it went down, I pulled it all the way, and then, got it out from the hole as which was empty so far, and then from above again I will repeat the same thing and insert the thread opposite to that hole. I will continue doing that till I feel like it is strong then I will make knot and fix it firmly with button. my job was done. 
Question: What color is the thread being used?
Output (English): It matched the dress.
