Theory:

"RUSH hour crowds jostle for position on the underground train platform. A slight girl, looking younger than her seventeen years, was nervous yet excited as she felt the vibrations of the approaching train. It was her first day at the prestigious Royal Academy of Music in London and daunting enough for any teenager fresh from a Scottish farm. But this aspiring musician faced a bigger challenge than most: she was profoundly deaf."
Explanation:
 
The author has set the tone of the story in a crowded railway station during the peak hour. A seventeen-year-old, small and slender girl feels the vibrations of the train coming to her platform. She is nervous and excited at the same time because she is going to the Royal Academy of Music in London for her first-day class. It is very intimidating for any teenager in this situation, but she also has a greater problem, that she is impaired of hearing. She cannot hear any sounds, and she can only feel the vibrations.
