Task: Question Answering
Input (English): Passage: We decided to have a barbecue to celebrate summer . First , we looked at our schedule and decided the best day to have a barbecue . We decided on the first Saturday in June . Then we talked about who we wanted to invite . Together we decided on about 30 people we would invite , including friends , family , co-workers and their families . We got in touch with them via text , phone and Facebook to let them know about the barbecue and see if they would be able to come . A few people had schedule conflicts but most were free and said that they looked forward to having a cook out . A few days before the barbecue we decided on what we would serve . A few of the guests had offered to bring chips , salads and beers but we provided most of the food so we made a shopping list of the items we needed . We bought soda , corn on the cob , burgers , buns , chicken , salmon , and ingredients for salad . On the day of the barbecue we set up the yard to be ready for our guests . I grilled the meats and corn as everyone mingled and chatted . The weather was great and we all enjoyed the food and had a great time . Question: When did they prepare the salads? Option1: before people arrived for the barbecue Option2: day after the barbecue
Output (English): before people arrived for the barbecue
