Read the following passage: A group of piano students love their teacher and develop a
passion for music because of him. One day, after a concert
featuring Chopin's music, they notice that the teacher has
changed. Instead of making the lessons fun and
instructive, he begins to enforce greater discipline. Some
students wonder whether they should continue, while
others begin to thrive because of the challenge. By the end
of the year, the teacher has fewer students, but they are
more talented and hardworking. Years later, the students
who had continued with the teacher find careers in the
music industry.
