Task: Question Answering
Input (English): Passage: Last month I went on a trip to Mexico . I was excited because I had never been to Mexico or flown on a plane before and I was going to get to do both . I booked my flight months in advance to be sure I would have transportation to my vacation destination . The day I was about to leave I went to the airport hours in advance because I was nervous and excited . A nice lady checked my ticket and confirmed that my flight was on schedule . I then proceeded to the security check station where officers checked my bags and personal belongings . After the quick screening and a short wait my plane boarded . After some short instructions the plane taxied the runway and then sped up in a flash . I watched as the tires left the ground and we took to the sky . After several hours in the air the plane descended and touched down on a runway in Mexico . I was excited to get my vacation started . Question: When did they find the seat? Option1: after booking their flight Option2: after boarding the plane
Output (English): after boarding the plane
