Task: Question Answering
Input (English): Passage: Yesterday I paid with a credit card . We went out to a restaurant , and since I did n't have cash on me , I decided to use my credit card . I gave the card to the waiter along with the bill , and he swiped my card to pay for the meal . This receipt had a spot to put how much I paid and also where I could leave a tip on my credit card . Since I did n't have cash , I added an additional 20 % tip on my credit card . It was a really easy process , so I used my credit card for the entire meal purchase . My wallet is much more empty now that I can use credit cards ! Question: In addition to a receipt, what did the waiter bring back after swiping Option1: cash Option2: their credit card
Output (English): their credit card
