Task: Question Answering
Input (English): Passage: My friend and I decided to go downtown to see the history museum . We decided the fastest and least expensive way to get there would be on the subway . Since we live in the suburbs move than 40 miles from downtown , we drove to the station at the end of the line and parked our car .  We paid for our tickets and walked through the turn-style gate . When the train arrived , we waited until the door opened and we walked in . We found a seat for two and sat down before the train left the station .  When they announced the next stop was the museum , we got up and stood by the door . When the train stopped and the door opened , we walked onto the station platform and then up the stairs to the sidewalk above . Question: When did they go underground? Option1: when taking subway Option2: when driving
Output (English): when taking subway
