Problem:OPTIONS:
- teenagers are more difficult to teach
- Danish teenagers can learn Swedish faster than younger children
- adults are more logical than children
- the ability to learn languages increases with age

Read the following article and answer the question. Article: Most people think that the older you get, the harder it is to learn a new language. That is, they believe that children learn more easily and efficiently than adults. Thus, at some point in our lives, maybe around age 12 or 13, we lose the ability to learn languages well. Is this idea a fact or myth ? Is it true that children learn a foreign language more efficiently than adults? On the contrary, research studies suggest that the opposite may be true. One report, on 2,000 Danish children studying Swedish, concluded that the teenagers learned more, in less time, than the younger children. Another report, on Americans learning Russian, showed a direct improvement of ability over the age range tested; that is, the ability to learn increased as the age increased, from childhood to adulthood. There are several possible explanations for these findings. For one thing, adults know more about the world and therefore are able to understand meanings more easily than children. Moreover, adults can use logical thinking to help themselves see patterns in the language. Finally, adults have more self-discipline (self-control) than children. All in all, it seems that the common idea that children are better language learners than adults may not be a fact, but a myth. Question: The main idea of the passage is _ . Answer:
****
A: the ability to learn languages increases with age

Read the following article and answer the question. Article: Aged just 25,Gaga has become the icon . Born Stefani Germanotta , Gaga was a child who learnt to play the piano at the age of four .She wrote her first piano ballad at 13 and began performing at open nights a year later .But as a teenager she had a hard time at her strict Catholic school and admitted that she didn't like to obey. She sobbed during a recent HBO documentary: "I still sometimes feel like a loser kid in high school and I just have to pick myself up and tell myself that I'm a superstar every morning so that I can get through this day and be for my fans what they need for me to be. " But aged 17 Gaga managed to escape to New York University's Tisch School of the Arts and by 19 she signed to Def Jam Recordings but quickly dropped after three months .The star went on to write songs for the likes of Britney Spears ,New Kids on the Block , Fergie ,and the Pussycat Dolls but it was Akon who gave her first big break after they worked in pairs as songwriters at Interscope. She released her first album The Fame in 2008 and the rest is pop history--first singleJust Dancetopped the charts and follow-up Poker Face landed her a Grammy award .In 2009,she released The Fame Monster.Gaga was the queen of the Brit Awards in 2010 where she won three prizes .At the MTV Video Music Awards later that year, Gaga won eight prizes in all . Gaga has been busy working on her second album, Born This Way, which is set to be released on May 23.She has already released four singles from the album -the title track,Judas,The Edge of Glory and Hair. Question: Who help Gaga succeed at last ? Answer:

- New technology causes trouble for recyclers.
- Experts are trying to solve the tech-trash problem.
- New technology has both advantages and disadvantages.
- CRTs from old computer monitors and TVs harm the earth.

Read the following article and answer the question. Article: Picture a wasteland of old computer monitors and TVs, stretching as far as the eye can see. Imagine towers of boxes, all of them filled with broken glass and discarded electronic devices. Technology graveyards like this can be found in communities across the country. Experts say that landfills and warehouses will overflow unless a plan for the disposal and reuse of electronics is put into place . "We can't put electronics and glass aside and tell ourselves we'll deal with them later ," Lauren Roman , managing director of Transparent Planet said. Roman's group works to improve the disposal of electronic waste. She says about 660 million pounds of tech-trash is produced each year in the U.S. What's behind the tech trash pile-up ?About ten years ago ,major advances were made in computer and television technology . Manufacturers began producing devices like flat -paneled LCDs and plasma screen monitors. These new products provide a clearer image and take up less space than older models. It goes without saying that consumers choose them rather than heavy glass-based technologies. The new electronics are built with materials that are difficult to recycle. In addition, the new products have decreased the demand for recycled parts from the older monitors and screens. Older, heavier computer monitors and TVs used glass-based components called CRTs. CRTs have a high lead content and can be environmentally hazardous if not recycled properly . If crushed and put in landfills, the lead from CUTs could seep into groundwater and rivers, harming the water supply. For many years, plants and recycling programs safely processed CRTs. The recycled CRTs were reused in the construction of new monitors. Monitors being made today do not use glass tubes . "People are returning old -style TVs with CRTs , but no new ones are being made ," said Linnell. This is creating an imbalance in the amount of glass being disposed of and recycled properly. Many recycling companies have shut down. Others no longer have the resources or space... Question: What is the main idea of the passage? Answer:

Read the following article and answer the question. Article: Scientists are learning new things about Antarctica, the coldest place on Earth. For example, the Antarctic ice sheet is shrinking. A new study found that summer ice loss in parts of Antarctica was at its highest level in 1,000 years. The study showed that Antarctic ice was melting mostly from below ice shelves, where the water is warmer than the ice. Eric Rignot is an earth system expert at the University of California, Irvine. He also works for the American space agency, NASA. There he serves as senior research scientist at NASA's Jet Propulsion Laboratory, also in California. He says ice melting from below is responsible for 55 percent of the shelf loss from 2003 to 2008. That is a much higher rate than scientists thought earlier. Professor Rignot and his team used satellite observations, radar and computer models to measure features above the ice to learn what was going on below. The measurements show differences from one area to the next around the continent. The major ice shelves are called Ross, Filchner and Ronne. They make up two-thirds of Antarctica's ice shelves. But they are responsible for only 15 percent of the melting ice. The professor says even small changes, like changes in ocean flow driven by wind, can make a huge difference in the melting of the ice shelf. Sixty percent of the Earth's fresh water is held in the huge Antarctic ice sheet. Professor Rignot says the study will help experts predict how the continent reacts to warmer ocean waters and helps to cause rising sea levels around the world. The study was published in the journal Science. Question: How did Eric Rignot and his team do the research? Answer:
****
A:
They used satellite observations, radar and computer models to know the things happening below the ice.
