Read the following article and select the best answer. Article: Dickson Despommier, a public health professor at Columbia University in New York City developed an idea with his students nine years ago. They imagined people in cities growing crops inside a tall building. Tomatoes could grow on one floor of the skyscraper , potatoes on the next, small animals and fish on the floor above. This vertical farm, or "farmscraper", could have space for restaurants and other places that serve food, like schools or hospitals. They could serve foods that are truly locally grown. But why would anyone want to build a farm indoors in a city? Dickson Despommier believes it will become necessary. The world needs to find places to produce enough food to feed the growing population. Space, he says, is an all-important issue. The professor also points to the problems of traditional farms. They use a lot of freshwater. Their fertilizer and animal waste can pollute water resources. And their growing seasons can be limited. But inside the vertical farm, crops could grow all year. And there would be no wind to blow away soil. Farmers would not have to worry about too much or too little rain, or about hot summers, freezing winters or insects. And without insects there would be no need for chemicals to kill them. Farm machines that .use fossil fuels, like tractors, would not be needed either. And water could be recycled for drinking. "The vertical farm reuses everything, so there is no waste," says Professor Despommier. Even buildings could be saved. Old buildings could become new farms and provide jobs. The professor has been actively proposing the idea to cities as far away as Dubai and Canada. But so far it exists only in plans and drawings, and a model at the Museum of Science and Industry in Chicago. Critics say building a farmscraper would cost too much, especially considering the price of land in many cities. Dickson Despommier estimates the cost at about twenty to thirty million dollars. But he says the building would not have to be very tall. And his graduate students have found many... Question: Which of the following is true according to the passage? - A vertical farm has been built in Chicago. - Old buildings could be changed into new farms. - Traditional farms use less water but pollute more water - There are some vertical farms being put into use in Canada.
Old buildings could be changed into new farms.

Read the following article and select the best answer. Article: From the moment that an animal is born it has to make decisions. It has to decide which of the things around it are for eating, and which are to be avoided; when to attack and when to run away. The animal is, in fact, playing a complicated and potentially dangerous game with its environment, discomfort or destruction. This is a difficult and unpleasant business and few animals would survive if they had to start from the beginning and learn about the world wholly by trial and error, for there are too many possible decisions which would prove fatal. So we find, in practice, that the game is always arranged in favor of the young animal in one way or another. Either the animal is protected during the early stages of its learning about the world around it, or the knowledge of which way to respond is built into its nervous system from the start. The fact that animals behave sensibly can be attributed partly to what we might call genetic learning, to distinguish it from individual learning that an animal does in the cause of its own life time. Genetic learning is learning by a species as a whole, and it is achieved by selection of those members of each generation that happen to behave in the right way. However, genetic learning depends upon a prediction that the future will more or less exactly resemble the past. The more variable individual experience is likely to be, the less efficient is genetic learning as a means of getting over the problems of the survival game. It is not surprising to find that very few species indeed depend wholly upon genetic learning. In the great majority of animals, behavior is a compound of individual experience added to the action patterns animals are born with.That is why animals can survive. Question: The survival game is considered complicated and potentially very dangerous because _ . - decisions made by animals may prove fatal - animals are often in danger of being attacked - animals make decisions entirely by trial - environment is not fit for animals to survive
decisions made by animals may prove fatal

Q: Read the following article and select the best answer. Article: A Chinese space capsule carrying three crew members has returned to Earth following a 13-day mission . Images of the capsule landing in Inner Mongolia at 10:05 local time were shown live on television. The astronauts, including China's first woman in space, carried out a successful manual docking with the Tiangong-1 laboratory module. This is a key step towards China's goal of building a space station by 2020. Premier Wen Jiabao praised it as a "complete success". "This is another outstanding contribution by the Chinese people to humanity's efforts to explore and use space," Mr Wen said in Beijing. "It feels so good to stand on Earth, and it feels even better to be home," astronaut Liu Wang was quoted by national broadcaster CCTV as saying. "Tiangong-1, our home in space, was comfortable and pleasant. We're very proud of our nation, " female astronaut Liu Yang said. The crew of the Shenzhou-9 craft successfully carried out the country's manual docking operation earlier in the week. The delicate procedure, which involved bringing together two orbiting objects travelling at thousands of miles an hour, was mastered by USSR and US space teams in the 1960s. The crew also carried out automatic docking of the two crafts in the process. The three astronauts returned to the Shenzhou-9 spacecraft on Thursday and performed a manual separation from the space laboratory. They touched down in Inner Mongolia's Siziwang county on Friday, with the capsule equipped with a parachute to slow its approach. Ms Liu, 33, is a major in China's air force from the central province of Henan. On China's Tencent QQ messaging service, she goes by the name "little Flying knight". She was selected into China's space programme only two years ago, but she did particularly well, the official news agency Xinhua says. The Shenzhou-9 spacecraft was launched on 16 June. Question: What can be the best title for the text? - A successful Space Travel - Tiangong-1, Special Home in Space - Liu Yang, China's First Woman in Space - China's Shouzhou-9 Spacecraft Returns to Earth
A: China's Shouzhou-9 Spacecraft Returns to Earth

*Question*
Read the following article and select the best answer. Article: As students and teachers returned to school on Monday after the publication of performance ratings for 18,000 teachers, many parents said they were giving the reports serious thought. Yet there was an equal measure of skepticism among parents that test scores have any relationship with teachers' competence. Some said they already knew how good a teacher was by walking into the classroom or by monitoring their children's progress. "I'm the kind of person who likes to see for themselves," a father in Queens said. Others worried about how their fellow parents, perhaps ones _ , might respond. Will they demand a new teacher? Move their children to a new school? Elizabeth Sane, the mother of a fourth grader at the Ella Baker School, a kindergarten-through-eighth-grade school on the Upper East Side, said that her daughter was switched to a different teacher's class over the summer, and that it was "like adding salt to the wound" when she saw the high ratings for her daughter's previous teacher. Her daughter's teacher this year did not receive a rating because he previously taught high school. Ms. Sane said that the rating was not the only factor that influenced how she assessed a teacher's performance, but that the data used for teacher evaluations mattered. But other parents dropping their children off at the Ella Baker School said they did not trust teacher ratings based on test scores any more than they wanted their children's learning measured only by the state exams. "Some people take it as the final word, but it doesn't change who they are as teachers. The ratings aren't accurate, and the whole student testing thing needs to be thrown out," said Lydia Delgado, whose child is in the second grade. Question: The attitude of the author towards the way to assess teachers' competence is _ . - supportive - critical - indifferent - objective
**Answer**
objective
