(1) As Aoi Kimura lay in her single room within the women's dormitory located underneath Tokyo Station, she realized that there was nothing more terrifying in the world than the first day of work. Well, it wasn't really her first day, she admitted to herself. She had joined the train company two years priot, performing different tasks at the train station near her home. (2) She had impressed her supervisors, meaning she was worthy of a promotion to train conductor. Her beige uniform freshly laundered and pressed, hung near the door. If she could perform well over the next three years, then maybe, just maybe, they'd let her drive the bullet train-the Shinkansen. (3) Aoi was already out of bed before the alarm on the far wall started howling. Switching it off before it could sound, she donned her uniform and did her hair and makeup Everything in its proper place, she left the room with her overnight bag and made the short walk down to the employee rest area. Similarly dressed conductors and drivers were there drinking coffee and chatting happily. Aoi's empty stomach twisted at the thought of a stained uniform. Which statement summarizes the story's main idea? Train conductors play an important role on the Shinkansen New train conductors like Aoi need additional supervision. Train conductors must look and act professionally at all times. New train conductors like Aoi must live close to the station.
