Task: Question Answering
Input (English): Passage: I picked up a dozen eggs in a carton while I was at the grocery store . When I got home , I took two out before putting the carton into the refrigerator . I took a frying pan from the cabinet and put a tablespoon of butter into it so the eggs would not stick . I cracked the eggs open on the edge of a bowl one at a time , and put them into the bowl . I threw away the shells . I added a little bit of salt and pepper . Once they were combined , I turned the heat of my stove on to medium . I let the butter melt and then I added the eggs . After they started to cook , I used my whisk to move them around so that I got scrambled eggs instead of an omelet . The eggs got nice and fluffy . I put them onto a plate and enjoyed them with some toast . Question: when were the yolks and whites mixed together? Option1: after adding salt and pepper Option2: after the butter melted
Output (English): after adding salt and pepper
