Task: Question Answering
Input (English): Passage: I had been on a trip to Boston , and it was time for my flight home . I arrived at the airport ninety minutes before my flight was scheduled to leave to insure I had sufficient time to check in , pass through security and make it to the flight gate . I had confirmed my reservation ahead of time and printed out a boarding pass which I took with me to the airport . When I arrived I had luggage to check . There was a much shorter line for people who already had their boarding pass . They gave me receipts which I would need to claim my luggage at my destination . I put the receipts in my wallet so I would not loose them . I patiently waited in the line with the other passengers . It took 30 minutes to get through the line . At the screening check point they verified I was not carrying any dangerous items . I had 20 minutes to relax before my flight left . Question: How much time did this person have on arrival? Option1: 90 minutes. Option2: 20 minutes.
Output (English): 90 minutes.
