Input: Article: Alice always wanted to be a singer. Music was the most important thing in her life, but to tell you the truth, she took lessons for years, practiced every day, but in spite of all this, her voice didn't improve. Honestly, it didn't get better, it just got louder. Her teacher finally gave up and stopped the lessons, but Alice refused to quit  , and one day she decided to give a concert and invited her mere   teacher to attend.  The teacher was very worried about what to say after the performance. She knew it would be terrible and it was. She didn't want to tell a lie, but she didn't want to hurt Alice's feelings either. Finally, she got an idea and went backstage   to greet her former pupil. "Well," said Alice, "what did you think of my performance?" "My dear," said the teacher, "you'll never be better than you were tonight." 
 Answer: Alice didn't make any improvement in singing
