Read the following paragraph and answer the question that follows:

Musical theatre changed my life. When I was a child, I was always a problem for my parents. I never wanted to go to school, study my homework, or do my chores. No one knew how to control me. My mom once said that she was at her wits' end by the time I turned 13 years old. The truth was that I had become insecure, and I hid from my fears by pretending to be too "bored" to do any real work. That was when my parents signed me up for stage classes. Acting and singing not only showed me my true potential, they taught me an essential fact: life is a team effort, and we all have different skills that we use together to make progress. Through lessons, sweat, and tears, my experience of working in musical theatre has helped me become the well-rounded adult I am today. I am forever thankful to my parents for not giving up on me and for sending me to classes!
