Q: 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,"...

Q: Read the following article and select the best answer. Article: Everyone is born with their own built-in burglar alarms, called the sense of sight and sound.Unluckily, many of us go around with the alarm turned off. We don't see the stranger wandering outside the house next door. We don't notice the sounds from the flat upstairs. (Weren't they supposed to be on holiday?) The police can only do so much to prevent crime. There never can be enough of them to guard every home in every town. So they need your help in fighting with the burglars,the vandals , and the car thieves. Not, of course, by setting out to have a go every time you see something suspicious. It'll always be the job of the police to arrest criminals. But by acting as a line of communication between them and your community, for instance, you probably know far more about your immediate neighborhoods than the police ever could. A stranger in someone's garden would probably be far more obvious to you than it would to even the local police, if, of course, you were on the look-out. That's the whole idea behind the Neighborhood Watch schemes, springing up around the country to create a spirit of watchfulness within a community, anything suspicious being reported to the police. It's early days yet, but results so far are very encouraging. The crime figures are already dropping in many of the areas running the scheme. And all due to people like you. Question: The advertisement points out that many people _ . - are not ready to help the police - are not as watchful as they could be - don't look after their gardens well - don't tell their neighbors about their holidays
A: are not as watchful as they could be

Q: Read the following article and select the best answer. Article: This is a rather strange story but it is quite true. In December 1996, a burglar broke into a golf club in a small town. When the police arrived to look into it, they found an unusual clue--- a piece of cheese with a bite-mark in it. The burglar had gone into the kitchen, and had eaten some food there. Then he had stolen some cigarettes and a little money. The police man in charge of the case guessed that the burglar was a local man. He thought that professional thieves would not bother to break into a golf club.He made enquires in the town and asked three suspects to come to the police station. When he questioned them about the burglary, they all denied stealing in the club.The policeman then gave each man a piece of cheese and asked them to bite it. He took the pieces of the cheese to a dentist and asked him to compare the bite-marks with that in the piece of cheese at the scene of the burglary. The policeman set free two of the suspects and questioned the third one. At first the man said that he was innocent . The policeman knew that the man was lying, so he encouraged him to talk until he began to contradict himself . The policeman told him about the bite-marks and the man had to admit his stealing. Question: What can be the best title for this story? - Bite-marks - Regretful burglar - Brave event - Professional burglar
A: Bite-marks

Q: Read the following article and select the best answer. Article: Billionaire Dennis Tito, tired of being told that we can't send humans to Mars just yet, on Wednesday revealed his scheme for launching two astronauts to the red planet as early as December 2017. Titled "Inspiration Mars," the flyby mission would exploit a rare line of Earth and Mars that minimizes the time and the fuel it would take to get to Mars and back home again. The astronauts would come within 100 miles of the Martian surface before being taken back to Earth. "It would be a voyage of around 800 million miles around the sun in 501 days," Tito testified Wednesday at a hearing of the House subcommittee on space. "No longer is a Mars flyby mission just one more theoretical idea. It can be done. Not in a matter of decades, but in a few years." Tito is a former engineer who made a fortune in investment management and, in 2001, became the first person to pay his way into space, buying a seat on a Russian rocket. Now he's pitching Inspiration Mars as a national priority for the United States. Grab this rare chance to go to Mars quickly or risk seeing China or Russia get there first, he told members of Congress. Tito mentioned a backup plan that would offer Inspiration Mars four more years of development time. Another line of planets in 2021 offers a second chance to go to Mars fairly quickly, but the journey would last 80 days longer and require that the astronauts fly much closer to the sun, within the orbit of Venus, in one portion of the trip. That would add to the already considerable radiation hazards. When Tito talked of the idea of Inspiration Mars early this year, he thought he could use primarily private rockets and minimize the need for NASA involvement. But the possibility study led Tito back to NASA. NASA is building a huge rocket, the Space Launch System, that is supposed to be ready for its originally, uncrewed test flight in 2017. The second launch, carrying a crew in NASA's new Orion capsule for the first time, isn't scheduled until 2021. Tito's plan would essentially borrow the SLS for the... Question: Which of the following is not true according to the passage? - It will take private donors about $300 million for the mission according to "Inspiration Mars'. - Tito plans to launch two astronauts to the Mars in December 2017. - The Space Launch System is supposed to be ready for its first test flight in 2017. - "Inspiration Mars' would be a voyage of around 800 million miles around the Mars in 501 days,"
