Read the following article and select the best answer. Article: Have you seen Jurassic Park? In this film, scientists use DNA kept for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and more dangerous than expected. That's nothing more than a fiction. But could we really clone endangered animals? To date, the most successful attempt to do so was the cloning of a gaur, a rare ox-like animal from southeast Asia. Scientists used a cow to bring the cloned baby gaur, named Noah. Two days after birth, however, Noah died from a common bacterial infection. Other endangered species that may be cloned include the African bongo antelope , the Sumatran tiger, the cheetah , and the giant panda. Next, could we really clone extinct animals? In theory? Yes. To do this, you need a well-kept source of DNA from the extinct animals such as wool mammoth , Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a surrogate mother. In reality? Probably not. On the one hand, it's not likely that extinct animals' DNA could survive undamaged for such a long time. Cloning extinct animals as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly well-preserved DNA. On the other hand, for example, a gaur can have a cow as _ , definitely not a monkey. But what about an extinct animal as unique as the panda? What species could possibly serve as a surrogate mother? Cloning presents many exciting possibilities. However, even if extinct animals are brought back, they could not survive in today's world. Not only do most extinct animals have no habitat to live in, but the other plants and animals they depended on for food may also be gone as well. Question: Which of the following statements is true according the passage? - Jurassic Park is a cloned animal. - The cloned creatures are the same as the real one. - We could clone extinct animals in reality. - We could clone extinct animals in theory.
We could clone extinct animals in theory.

Read the following article and select the best answer. Article: The name might sound like that of a superhero, but Pooperman's task is much more basic. He, or she, is trying to shame the irresponsible dog owners of Lincoln into cleaning up behind their pets. Pooperman sticks notes into dog waste that owners have failed to clean up, warning them not to do it again. The typed notes read, "Don't leave it. You might be the one who steps in it the next time you walk this way." While welcoming the purpose of the message, local government officers have _ Pooperman for producing even more rubbish. They say they would prefer it if people told them when there was a problem rather than adding to the rubbish problem. The city of Lincoln government's environmental officer, Tony Garner, said, "The public can help instead by observing dog owners to make sure they clean up after their pets, perhaps asking them to remove the waste if they try to leave it." "If this doesn't work we can take action -- people can tell us who the owner is, give us a description of the owner and the dog, or simply tell us when and where they allow their dog to produce the waste." "We can then focus our patrols and take action against irresponsible owners." Sue Grace, a dog owner from Birchwood, Lincs, said, "I always clean up after my dog. It's very irresponsible if you don't." "There's nothing worse than stepping in dog waste or dragging your long lead through it, but I don't know that putting notes on it is the answer." "It's good that the local government is fighting against dog waste, though it might take one or two prosecutions to make any difference." Question: The dog owner Sue Grace believes that _ . - the local dog owners are irresponsible - Pooperman is responsible and doing an effective job - the law may play a role in fighting against dog waste - the local government's fighting against dog waste is successful Skydive Greene County
the law may play a role in fighting against dog waste

Read the following article and select the best answer. Article: Pupils work harder in lessons if they are taught by a man, a study has claimed. Male teachers are more likely to improve pupils' self-esteem and are judged by pupils to be more fair, according to a study published by the Department for Education. But there is a significant shortage of male teachers, especially in primary schools, with reports last month indicating that almost one in three primaries has an all-female teaching staff. The latest figures heightened fears that schools are becoming dominated by women and children are being denied access to male role models in the classroom. Researchers at the London School of Economics and Westminster University conducted an experiment in which each of 1,200 pupils in 29 schools was given PS2. They could use the money to "buy" up to 10 questions at a cost of 20p each, which they then had to answer. If they were right they were given an extra 20p, but if they were wrong they lost 20p. Boys and girls who had a male teacher chose on average almost half a question more than those taught by women, indicating that they had a more positive outlook on the rewards of effort, the the study said. Researchers wrote: "One of the most significant results featured in this experiment is the positive effect of male teachers on effort. The experiment suggests that higher ability pupils either believed that the teacher would reward them more favorably or had a preference for working hard to please the teacher." According to the Good Teacher Training Guide, 86 per cent of new teachers entering primary schools are female, along with 62 per cent of those entering secondary schools. Professor Alan Smithers, of Buckingham University, said: "This is an interesting and somewhat surprising finding, but it does underline the importance of having a good mix of male and female teachers in classes." Question: Which of the following is true of the passage? - Male teachers are more fair than female teachers. - Now most primary schools are in need of teachers. - Most people are afraid that their children can't get access to male teachers. - The author thinks that male teachers are better than female teachers.
Most people are afraid that their children can't get access to male teachers.
