Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy. Some scientists believe that birds do sing some of the time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory. Do you know what a 'territory' is? A territory is an area that an animal, usually the male, claims as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger enter your territory and threaten you, you may shout. Probably this is enough to frighten him away. If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird's song, and it is usually enough to keep an outsider away. Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs. You can see that birds have a language of their own. Most of it has something to do with attracting mates and setting up territories. Options: A By comparing birds with human beings. B By reporting experiment results. C By describing birds' daily life. D By telling a bird's story. Answer: A By comparing birds with human beings. Question:

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: The piano on which Mozart wrote all of his late works returned home to Vienna for the first time since his death in 1791.The piano will stand in his former Vienna home, now a museum, for two weeks, ending in a concert of the works by Mozart. Mozart bought the instrument from Anton Walter, the most famous piano maker of his time, in 1782.He wrote more than 50 works for the piano on it, many of them in the apartment in Vienna.After Mozart's death, Constanze, Mozart's wife, gave the instrument to their elder surviving son, Carl Thomas, who donated it to the Mozarteum Salzburg on what would have been the composer's 100th birthday.The piano is now part of the permanent exhibition in the Austrian city of Salzburg. " It was very hard to let it go," said Matthias Schulz, director of the Mozarteum Salzburg." If we didn' t know it was in the best hands, we wouldn' t have done it." The piano is much smaller and lighter than modern concert ones.Its sound is fresher and brighter than that of a modern piano, with lighter action and hammers . Piano restorer Josef Meingast, who has looked after the Mozart piano since 1975, said it was superior to any of its surviving copies.Meingast said he had to fight to replace the existing strings , dating from a 1973 restoration, with softer ones that produce a rounder sound thought to be more similar to what Mozart would have produced. Russian pianist Alexander Melnikov, who planned to give a concert of Mozart' s music on the piano on November 7, said he was privileged to play such an instrument.It's easily the biggest day of a musician' s life."
