Article: Dolphins are interesting animals and researchers find them interesting to watch. They don't have hands, but can use tools to solve problems, just like us. Scientists have observed a dolphin trying to get a shy eel to come out of its hole by poking it with a dead fish. Many species of dolphin live in large societies. They have many different relationships and need a good communication system; they use a variety of sounds to communicate with each other. There is currently no evidence that dolphins have a language of their own. But scientists still have a lot to find out about these animals and so there are certain to be a few surprises in the future. At Kewalo Basin Marine Laboratory in Hawaii, the dolphin team have developed a sign langue to communicate with the dolphins, and the results are amazing. Not only do the dolphins understand the meaning of individual words, they also understand the significance of word order in a sentence. For example, when they were asked to 'touch the ball with your tail and then jump over it' they generally responded correctly and straight away, which showed that they understood the langue. Most mammals seem to enjoy play--but dolphins seems to like making their games as challenging as possible. On a beautiful day in 1997, researchers working at a beach, off the southern coast of Brazil, observed a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins approached the dog and then started throwing it into the air. The dog seemed to enjoy the 'game' and continued playing with the dolphins for more than an hour. From then on, different dogs were seem trying to interact with the dolphins. Dolphins live in a very different world to ourselves, but they are very good at our 'intelligence tests'. For example, they will jump out of the water when they hear a whistle noise. They do this because they will get a fish as a reward. There is still much to learn about these flexible problem-solvers, but from the evidence so far, it would seem as though... Question: Dolphins will jump out of the water when they hear a whistle noise in order to _ . Yes or no, is the answer "get some food"?
Yes

Article: Most of us think that when we step under a shower we're getting clean.We are, but we're also giving a home to lots of tiny little creatures we didn't even know about. A showerhead carries thousands of bacteria called Mycobacterium.These can cause problems like coughs and tiredness, and a general feeling of poorliness .When you turn on the water, the bacteria go from the showerhead onto and into your body. This is a finding of Norman R.Pace and his team at the University of Colorado, in the US.The scientists investigated bacteria in all kinds of human environment, including showers. Pace's team looked at 45 showerheads in nine American cities.They discovered that 30 percent of them had large amounts of flying Mycobacterium. But Pace said that they pose few threats to the health.Only those with a frail immune system might need to worry. He told the New York Times that the bactertia are not as unpleasant as might be thought.He said that having a shower is no more dangerous than anything else we do in the morning. But for those who feel sick about the idea of all those microorganisms , he had some advice. Let the water run for 30 seconds before getting into the shower.Why? The number of bacteria is smaller than when the water is just turned on.If that seems like a waste of water, he added that you could also change your showerhead every few months. But Pace had good news too.He has also been testing the air in US subways.Apart from iron particles , which are ground off the track by the wheels of trains, subway air is fresh.The reason is that a train's movement pumps fresh outdoor air into the tunnels . Pace explained that he wanted to understand the natural microbial environments of public places.This kind of knowledge might help _ the microbes to be used in a bioterrorist attack. Question: Pace's research into showers shows that _ . Yes or no, is the answer "shower water contains much less bacteria after being left to run for 30 second"?

No

Ques: Article: Now, there is a growing movement to pay the students in American schools---in some cases, even just for coming to class. Students at one school in New Mexico can earn up to three hundred dollars a year for good attendance. In Baltimore, Maryland, high scores in state graduation tests can be worth more than one hundred dollars. And a New Jersey school system plans to pay students fifty dollars a week to attend after---school tutoring programs. Schools that pay students can be found in more than one---fourth of the fifty states. Other schools pay students with food or other rewards. Robert Schaefer is a public education director. He says paying students may improve performance in the short term, but students develop false expectations for the future. He sees a lack of long term planning in these programs because of the pressure on schools to raise test scores. Public schools need to show improvement under the education reform law. Low---performing schools may lose their federal money; teachers and administrators may lose their jobs. Often these schools are in poor neighborhoods where getting students to go to school can be a continual problem. Critics say paying students sends a message that money is the only valuable reward. But some students say it makes school more exciting. And some teachers have reported getting more requests for extra help. In two thousand four, the city schools in Coshocton, Ohio, launched a program. They wanted to see if paying elementary school students as much as one hundred dollars would help in passing the state exams. Now, Eric Bettinger of Case Western Reserve University (EUCWRU) has reported mixed results. Math scores increased, but only white students were able to get paid. And there was no evidence of higher scores in reading, social studies and science. Official will decide later this year whether to continue the program. Question: Paying students who show improvement in tests _ . Yes or no, is the answer "is becoming a growing practice in the USA"?
Ans: No

Question: Article: LONDON (Reuters Life!) ---- Forget about talking your children into considering life as a doctor or a teacher and start training them for the talent show. A survey of British parents showed the aspirations of their children are greatly different from what they dreamed about when considering who they wanted to be when they grew up. Although astronaut still remains fairly high on the list of careers kids dream about these days, others like doctor and teacher have been taken the place of by the desire to win good name and money as a sporting hero, pop star or actor. The parents of children aged 5 to 11 said the choice of lawyer had dropped by only one place on a top 10 list to sixth, while teacher had dropped to ninth from top in the last 25 or more years. The survey for British TV channel "Watch" found a great difference between the genders of today's young people when compared with their parents' dreams 25 years or more ago. Playing professional football, being an astronaut and joining the firefighting service topped the boys' choices, while girls are more likely to be dreaming of taking to the stage as a pop star or actress or joining the medical profession. When asked what they would like their children to do for a living, today's parents still like the academic professions , with law and medicine scoring highly, while being a boss came third. Parents also praised job happiness above wealth when it comes to their hopes for their children. Nearly 70 percent of the parents surveyed thought that they failed to follow their dreams when it came to their career, with 37 percent thinking it was caused by a lack of aspiration and not having the necessary conditions. Question: According to the survey for British TV channel "Watch", which of the following is the boys' best career choice? Yes or no, is the answer "A firefighter"?
Answer:
No
