Read the following article and select the best answer. Article: A few years ago I was shopping with a friend and his 12-year-old daughter in downtown San Francisco.A street musician,whom my friend happened to know from his own musician day,was playing the saxophone on a street corner.His name was Clifford,and he had attracted a large crowd with his performance.After he finished,my friend introduced him to me and his daughter.Clifford asked her if she played any instrument.When she replied that she was taking trumpet lessons and played in her junior high school band,he said,"That's fine,little lady.Learn your instrument well and you can play anything."Somehow these simple yet wise words struck me as suitable not only for a trumpet player but also for a reader.If you learn to read well,you can read anything you want--not just newspapers and magazines,but more difficult material like philosophy,film criticism,military history--whatever interests you as your confidence grows.You would not be limited in any way.If you have the vocabulary -or at least a good dictionary near at hand--you can pick up a book,concentrate on it, and make sense of the writer's words. In the United States,reading instruction often ends at elementary school,so students sometimes have difficulty as they progress through school.They must take their assignments,armed only with their elementary,school reading skills.The result,too often,is frustration and loss of confidence.And the assigned reading in your college courses will be even greater than they were in high school.Developing Reading Skills is designed to accomplish several tasks:to show you the skills that will enable you to read with greater comprehension,to help you deal with reading assignment with confidence,and to teach you to become an active reader. Question: The talk between the girl and Clifford serves as an introduction to _ . - the importance of reading - the connection between playing instruments and reading - the necessity of learning to play an instrument - the variety of reading material
the connection between playing instruments and reading

Read the following article and select the best answer. Article: In many romantic movies or TV shows one scene always appears. It involves a handsome man standing outside a young woman's window, singing a love song to her to win her over. However, trying to woo a female with songs is not just something that humans do. A few animals sing love songs as well. Birds and elephants are romantic but the latest animal to _ a female might surprise you--it is the humble mouse. You may find it odd to find out that mice sing. We do not hear them because the frequency of their voice is so high. In fact, scientists have known for some time that male mice make special sounds to females, but it has always been assumed that the sounds are produced instinctively and randomly, with little thought going into the process. But new research suggests otherwise. When male mice with different voices were put in a cage together, scientists found that they would gradually change their pitches to sound like one another. But when a female mouse was put in the cage with two males, one male would change his pitch to match the other. "It was usually the smaller animal changing the pitch to match the larger animal," professor Erich Jarvis, leader of the study, from Duke University, US, told BBC News. This ability, known as vocal learning, is rare in the natural world. It had been thought to be limited to some birds, such as parrots--as well as whales and dolphins. The latest findings challenge the long-held opinion that mice cannot learn to adapt their voices. Scientists also found the part of the brain that controls the mice's singing ability. In the experiment, they damaged the cells in this part of the mice's brain and found that the animals couldn't keep their songs in pitch or repeat them any more. This also happened when the mice became deaf. Jarvis said that this finding had changed his understanding of the way mice make sound. "In mice we find that the pathways that are at least modulating these vocalizations are in the forebrain, in places where you actually find them in humans,"... Question: What do parrots, whales and dolphins have in common according to the passage? - They are all animals well-known for their smart appearances. - They are often chosen to carry out scientific experiments on. - They all have the ability to learn to adapt their voices. - Their numbers are quite limited in the natural world.
(Answer)
They all have the ability to learn to adapt their voices.
