Task: Question Answering
Input (English): Passage: When I went on vacation last year with my parents , we took a trip on a train for part of it . We picked the route we wanted to take to go visit my uncle , and had everything ready the day before , such as our suitcases . When the day arrived for us to go , my dad drove us to the train station where we parked in a designated lot , since we would be returning to the same train station . We had some extra time , so we wandered around and found a little gift shop where we could buy souvenirs . When it was time to board our train , we walked through the station to get to the correct area . There were long hallways to get there , and then we went up a concrete pathway to where the train was outside . We had to give the ticket taker our tickets so she could verify we were getting on the right train . We stored our luggage and prepared for the train to begin its journey . Once it was time to leave , we watched out the windows at all the passing scenery . After awhile , we all started doing our own thing like reading or playing cards to pass the time . Question: When did they and their parents purchase their train tickets? Option1: After arriving at uncle's home Option2: Prior to boarding train
Output (English): Prior to boarding train
