Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: When Iain Douglas-Hamilton first started studying elephants in Africa,he had to invent ways of tracking the big animals. Over the course of 40 years in the field, the zoologist learned how to fly airplanes and use some high-tech means to follow their movements. He also learned how to get out of the way fast. "I learned how to climb trees very quickly," says Dr. Douglas-Hamilton, winner of the 2010 Indianapolis Prize. As co-founder of Save the Elephants, he has also learned to be an activist, author, and politician. When Douglas-Hamilton left Tanzania, in East Africa, in 1970 to study at Oxford University in Britain, he left behind "an elephants' paradise ."But when he returned in 1972, the country's national parks looked more like a war zone. Douglas-Hamilton often found more dead elephants than living ones. Dr. Douglas-Hamilton now lives in Kenya with his wife, Oria, who co-founded Save the Elephants. Together they have written two books, "Battle for the Elephants" and " Among the Elephants". During the height of the ivory poaching ,Douglas-Hamilton flew in small planes, helping bring back elephants in Uganda from the edge of extinction. He's been repeatedly shot at and has survived plane crashes, floods and diseases. He fought for years for a worldwide ban on ivory sales, which finally took effect in 1989. Douglas-Hamilton pioneered the scientific study of elephant social behavior. Among his discoveries: Elephants have a society controlled by female elephants and travel in families. In 2009, he worked to save a rare group of desert elephants in Mali from the worst dry weather in Mali's history. There have been other successes, particularly in East and Southern Africa. Douglas--Hamilton has proposed the idea of a mobile national park, where the protected land would follow elephants as they travel. No country has yet accepted it. Even after decades of research, Douglas-Hamilton still enjoys the company of elephants. "I love to sit with them and be with them, "he says. "I have the greatest joy just to be...

D Douglas-Hamilton's fight for a mobile national park. Answer: B Douglas-Hamilton's devotion to protecting elephants. Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Marriages improve after children grow up and move out,according to an academic study, which suggests an "empty nest" is not always a bad thing. Popular wisdom has it that parents' relationships may suffer once their young fly the coop, because they feel they have lost their purpose in life.However, a new study by researchers at the University of California, Berkeley, has found that many couples actually feel happier when their children leave home because they are able to enjoy spending time together. In total,123 American mothers born in the 1930s were tracked for 18 years and asked to rate their satisfaction levels shortly after marrying, when they were bringing up babies, once their children reached their teenage years and finally at age 61, when almost all had "empty nests". Although not all said they were happier in general, most claimed their marriages had improved since their children had left home. Researchers believe this is not just because the spouses were spending more time together, but because they were able to enjoy each other's company more. One of the participants in the study,which is published in the journal Psychological Science,said:"Once the kids grow up...there's some of that stress removed...that responsibility removed,so things are a little more relaxed." Psychologist Sara Gorchoff,who carried out the investigation,said: "The takehome message for couples with young children is 'hang in there'." Her coauthor Oliver John added:"Don't wait until your kids leave home to schedule quality time with your partner." However, Dr Dorothy Rowe,from the British Psychological Society,said the effects of living in an "empty nest" will depend on the parents' relationship with their children."If you're just waiting for them to leave home so you can get on with your life,then of course you'll be pleased to see them go," she said, "But if you've built your life around your children you'll be terribly lonely.For some parents,their world falls apart when their children leave." Options: A parents should build their life around their kids B parents should schedule quality time with each other before kids leave home C parents' relationship with their kids has no effect on marriages at all D parents should be pleased to see their kids leave home Answer: B parents should schedule quality time with each other before kids leave home Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: London's newest skyscraper is called the Shard and it cost about 430 million pounds to build. At a height of almost 310 metres, it is the tallest building in Europe. The Shard has completely changed the appearance of London. However, not everyone thinks that it is a change for the better. The Shard was designed by the famous Italian architect Renzo Piano. When he began designing the Shard for London, Piano wanted a very tall building that looked like a spire * He wanted the glass surfaces to reflect the sky and the city. The sides of the building aren't regular. So the building has an unusual shape. It looks like a very thin,sharp piece of broken glass. And that is how the building got the name: the Shard. Piano says that the spire shape of the Shard is part of a great London tradition. The shape reminds him of the spires of the churches of London or the tall masts of the ships that were once on the river Thames. The Shard has 87 floors. At the top, there is an observatory. At the moment the building is empty, but eventually there will be a five-star hotel. There will also be top quality restaurants, apartments and offices. Before building work began, a lot of people didn't want the Shard though the plans were approved. Now they are still unhappy about the Shard. Some critics say that such a tall skyscraper might be good in a city like New York, but not in London. They say that the best thing about the Shard is its spire shape. But that is the only thing. There is no decoration, only flat surfaces. The Egyptians did that 4,500 years ago. They also think the Shard is too big for London. It destroys the beauty of the city. Other critics don't like what the Shard seems to represent. They say that the Shard shows how London is becoming more unequal. Only very rich people can afford to buy the expensive private apartments and stay in the hotel. But the people who live near the Shard are among the poorest in London. So the Shard seems a symbol of the division in society between the very rich and the poor. The...
