I'm taking a test and have to guess the right answer to the question after the article. Article: Have you ever wondered why stems grow upwards and roots downwards? Why plants always seem to turn, towards the light and climbing plants run up rather than down? The answer is simple:auxin,a chemical substance that controls growth in plants. Auxin gives away its secrets Auxin is a plant hormone . Darwin was already interested in it in the 19th century. Only in recent years, however, has the hormone started to give away its secrets ,thanks to intensive molecular research.Auxin is produced in the young,growing parts of plants and then transported throughout the plant-to a low -lying stem for example. The stem needs to straighten out as soon as possible to be able to absorb the topside,resulting in the underside growing faster and the stem straightening out. For the same reason, plants in front of windows will always turn to the light . This active regulation of auxin transport allows plants to take ideal advantage of local and changing conditions. A new means of transport for auxin? The transport of auxin through the plant plays a vital role. And ,from all appearances,it is not a simple matter. The researchers identified an important new link and means of transport for auxin: PILS proteins . PILS proteins are vital for auxin-dependent plant growth and adjust the intracellular storage of the hormone. It is exactly this compartmentalizing of auxin that seems functionally important for the various developmental processes. Growing crops more efficiently: the right amount of auxin in the right place Higher auxin levels at the right moment and in the right place result in better growth and greater harvest. Better adjustment of auxin levels would make plants grow more efficiently. The researchers hope to contribute to the development of more efficient growing processes by continuing to sort out auxin transport processes. Question: Which of the following can be the best title for this passage? Options: A: Why Plants Grow Towards the Light? B: Darwin's Dream Has Come True C: How Did Scientists Find Out the Secret? D: A New Way of the Growing of Plants

I'm taking a test and have to guess the right answer to the question after the article. Article: Besides providing an ideal environment for sea plants and animals to live in, seawater has other values, one of which is that it constantly moves, and its movements produce energy. The most obvious movements are waves and the tides. Winds causes the waves, and the gravitational pull of the moon and the son causes tides. In places like the Bay of Fundy in Canada, the difference between the high and low tide level can be as much as 40 feet. France and Britain are now trying to use energy in the tides to produce electricity. Waves can produce electricity and some experiments are taking place to learn more about this. One of the most encouraging areas of research uses the difference between the temperature of seawater at the surface and deep down to produce electricity. Question: According to the passage, which of the following is not true? Options: A: The temperature difference of seawater can produce electricity. B: The energy in the tides can produce electricity. C: Waves can produce electricity. D: The plants and animals in the ocean can produce electricity.

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Though she is already one of the most famous pop stars of the 21st century, you've probably never heard of a 25-year-old singer, song writer named Stefani Germanotta --- but that's only because almost everyone knows her by her stage name, Lady Gaga. Born in New York City in 1986, Lady Gaga enjoyed music, singing and dancing from an early age: she started playing the piano when only four years old and loved performing in musicals at high school. At 17, she went to a special school for the arts but later left because she wanted to become a professional singer as soon as possible. She became a global star with her first album The Fame in 2008 and followed it in 2009 with The Fame Monster. Earlier this year she released a single, "Born this Way," which broke the record for quickest sales for a piece of music on iTunes, with one million downloads in only five days. Her third album, also called Born this Way, went on sale in May this year. www.ks5u.com Because of how much money she earns, how much she is written and talked about in the media, and how many internet searches are made with her name, Forbes magazine recently put her at number one in its list of the "world's most powerful celebrities ." Most music critics say that what makes Lady Gaga's music stand out are her strong voice and also the strong electronic rhythm of most of her songs, which makes them popular in nightclubs. They also say her music often sounds like the work of other artists, and she herself is quite open about the fact that groups such as Queen and female singers such as Madonna have been a big influence on her. More original than her music, perhaps, is the way she looks. A big part of her image is her outlandish clothes, with her strangest piece of clothing probably having been a dress made partly out of meat, which she wore once in 2010. Part of what has made Lady Gaga so famous so quickly is the way she has used social media. She has over 30 million Facebook friends, for example, and almost 10 million followers on Twitter. Question: What can we learn about "iTunes"? It is _ . Options: A: a single album of popular songs on sale. B: a mobile phone which shows live music performances. C: a center where pop stars get together. D: a software used to download music from the Internet.

I'm taking a test and have to guess the right answer to the question after the article. Article: My father's reaction to the bank building at 43rd Street and Fifth Avenue in New York city was immediate and definite: "You won't catch me putting my money in there!" he declared, "Not in that glass box!" Of course, my father is a gentleman of the old school, a member of the generation to whom a good deal of modern architecture is upsetting, but I am convinced that his negative response was not so much to the architecture as to a violation of his concept of the nature of money. In his generation money was thought of as a real commodity that could be carried, or stolen. Consequently, to attract the custom of a sensible man, a bank had to have heavy walls, barred windows, and bronze doors, to affirm the fact, however untrue, that money would be safe inside. If a building's design made it appear impenetrable , the institution was necessarily reliable, and the meaning of the heavy wall as an architecture symbol reflected people's prevailing attitude toward money. But the attitude toward money has, of course, changed. Excepting pocket money, cash of any kind is now rarely used; money as a has largely been replaced by credit. A deficit economy, accompanied by huge expansion, has led us to think of money as product of the creative imagination. The banker no longer offers us a safe: he offers us a service in which the most valuable element is the creativity for the invention of large numbers. It is in no way surprising, in view of this change in attitude, that we are witnessing the disappearance of the heavy-walled bank. Just as the older bank emphasized its strength, this bank by its architecture boasts of imaginative powers. From this point of view it is hard to say where architecture ends and human assertion begins. Question: 37. How do the older generation and the younger one think about money respectively? Options: A: The former thinks more of money than the latter. B: The younger generation values money more than the older generation. C: Both generations rely on the imaginative power of bankers to make money. D: To the former money is a real commodity but to the latter be a means to produce more money.
