Read the following article and select the best answer. Article: Directions : Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A,B, C and D. Choose the one that fits best according to the information given in the passage When top engineers in Germany wanted to build a more energy-efficient car, they headed to the natural history museum to study dolphins and sharks. But it was the boxfish that interested them. "We were surprised when this clumsy-looking fish became our model for designing an aerodynamic car",says Thomas Weber. He is the research and development chief for the car company Daimler. An aerodynamic design reduces wind drag and increases fuel efficiency. The boxfish may look clumsy, but it can start, stop ,back up and zigzag through the water with ease. And it does all this using surprisingly little energy. Daimler's bionic car is modeled on the fish's boxy skeletal system. Like the fish, the car is fast and drives easily. It's efficient too. The science behind nature-inspired inventions is called biomimicry . Biologist Janine Benyus came up with the term. As co-founder of the Biomimicry Guild, she has worked with cereal companies,sneaker designers and others to develop products based on Nature's best ideas. This month ,the Nature's 100 Best List will be revealed at the World Conservation Congress in Barcelona ,Spain. Benyus co-authored the list of nature inspired designs with economist Gunter Pauli. In Zimbabwe ,a country in southern Africa ,engineers designed energy-efficient buildings modeled on termite mounds . The buildings use vents to keep the air flowing and the temperature cool. A company in Atlanta ,US ,developed a self-cleaning paint modeled on the lotus leaf. When the paint dries ,it becomes bumpy ,just like the lotus leaf. Rain drops form on the bumps and roll off ,carrying dirt along with them. Nature has done billions of years of research. Only the best-designed products have survived. Companies owe Mother Nature a debt for all that... Question: Which is TRUE according to the passage? - In America a self-cleaning paint was modeled on the lotus flower. - Zimbabwe engineers learned from termites to create highly advanced heating systems. - After the boxfish ,many other ideas of new products are borrowed from nature. - Nature is a good source to turn to for improving technology.
Nature is a good source to turn to for improving technology.

Read the following article and select the best answer. Article: Television will turn 86 years old on September 7, 2013, and it has never looked better. In its youth, television was a piece of furniture with a tiny, round screen showing unclear pictures of lowbudget programs. In spite of its shortcomings, it became well-received. Between 1950 and 1963, the number of American families with a television jumped from 9% to 92% of the population. As the audience got larger, the technology got better. Television sets became more reliable through the 1960s. Both of the reception and the picture improved. The major networks started broadcasting programs in color. Even greater improvements were coming according to Sanford Brown, who wrote an article forthe Postin 1967. Surprisingly, just about every prediction he made in the article became a reality. For example: All sets in the notdistant future will be color instruments. He also predicted that TV sets would become smaller, simpler, more reliable and less expensive and may forever put the TV repairman out of work. Smaller sets do not, of course, mean smaller screens. TV engineers expect screens to get much bigger. However, today's 3D TV is even farther away, if it's coming at all. There is some doubt whether the public would be eager to pay for it, in view of people's cold reception given to 3D movies. But the technology with the greatest potential, according to Brown, was cable television , which was still in its early stages then. As he predicted, the future of cable television was highly interactive. It wasn't cable television that gave Americans their electronic connection to the world, however. It was the Internet. He even foresaw the future office: using picture phones, bigscreen televisions for conferences, and computers providing information, at the touch of a button. Brown ever said, "The future of television is no longer a question of what we can invent. It's a question of what we want." Question: Which of the followings did Sanford Brown fail to predict? - Television's good quality. - The invention of 3D TV. - The more functions of TV. - The potential of cable TV.
(Answer)
The invention of 3D TV.

Ques:Read the following article and select the best answer. Article: A new study says one part of the human brain may become smaller as the result of a condition known as jet lag. Jet lag results from flying long distances in an airplane. Jet lag interferes with a person's normal times for sleeping and waking. People with jet lag may feel extremely tired for several days. They also may have problems thinking clearly and remembering. Kwangwook Cho is a researcher at the University of Bristol in Britain. He reported the findings of his jet lag study in the publication Nature Neuroscience. The study involved twenty young women who worked for international airlines. The women had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights. The other half spent more than fourteen days in their home areas. Mister Cho took some fluid from the women's mouths to measure levels of a hormone that increases during stress. He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains using magnetic resonance imaging. This is a way to measure the size of the brain's temporal lobes. It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones. Mister Cho says he believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory. Scientists say more tests are needed to study the... Question: According to the text, jet lag _ . - can cause difficulties in speaking - can make people feel tired for a few weeks - is the illness only found in people who work on the airplanes - can be caused by flying over several time zones in an airplane

can be caused by flying over several time zones in an airplane
