One example: Article: There are a lot of public libraries in Britain. These libraries have more than one hundred and fifteen million books, not including those libraries of public schools. Public libraries not only lend books, music records but also help children, patients in hospitals and others to get special play readings, film shows and so on. The first public libraries were founded in about the year 1850. Today's public libraries usually have a reading-room, a lending room and a reference room. The greatest and most famous library in Britain is that of the British Library in London. It was founded in 1973 and has over 10, 000, 000 books. It has nearly every magazine, newspaper and book published in Britain and other parts across the world.

Now, solve this: Article: Robby was 11 when his mother dropped him off for his first piano lesson. I prefer students begin at an earlier age. Robby insisted that it had always been his mother's dream to hear him play the piano, so I took him in as a student. Robby tried and tried while I listened and encouraged him and gave him more instructions . But he just did not have any inborn ability. I only saw his mother from a distance. She always waved and smiled but never came in. Then one day Robby stopped coming to our lessons. I thought about calling him but I guessed he had decided to try something else. _ . However, several weeks before the recital of my students, Robby came,telling me that he never stopped practicing and begged me to allow him to take part. I agreed but I made him perform last in the program, so I could always save his poor performance through my "curtain closer". I was surprised when he announced that he had chosen one piece of Mozart's. Never had I heard a piece of Mozart's played so well by someone at his age. When he finished, everyone was cheering. I ran up and put my arms around Robby in joy. "I've never heard you play like that, Robby! How'd you do it?" "Well, Miss Hondorf. Do you remember I told you my mom was sick? Actually she died this morning. She was born deaf so tonight was the first time she could hear me play. I wanted to make it special. I knew I could." That night, Robby was the teacher and I was the student. He taught me so many important things about life.
Answer: His mother was too sick to send him to the piano lessons.
Solution:
Why did Robby stop coming to the piano lessons suddenly?
