Task: Question Answering
Input (English): I had a friend drop me off at the terminal so I did not have to park. I went inside to the counter of the airline I was flying with. I handed the agent my passport and asked if I was checking bags, I told them I was checking one bag so they had me run my debit card to pay the baggage fee. The agent printed my boarding pass and handed it to me along with my passport and a sticker with a number to match the sticker they attached to my suitcase. He told me that the flight was boarding at 6:15 so I had more than enough time. I thanked the agent and left my suitcase which they put on a sticker on and put on the conveyor belt behind the counter. I thanked the agent and double checked that I had my boarding pass and passport and proceeded to security. 
Question: How many bags did they have checked?
Output (English): One
