Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: The oil from palms has a wide variety of uses and is found in food, soaps and shampoos. An international team found a gene that made some of the trees produce more oil than others. Dr Rajinder Singh, from government agency the Malaysian Palm Oil Board, said, "The oil palm has three fruit forms: a thick-shelled type --the Dura; those that don't have any shell--the Pisifera; a third form produced as a cross between the thick shell and the one without the shell--the Tenera, which are more of the fleshy fruit to produce the oil," and the researchers identified the gene producing this trait. While oil palm growers attempt to grow only the thin-shelled Tenera variety, up to 10% of the seeds can be contaminated , and turn out to be the other less oily plants. Prof. Martienssen, from the Cold Spring Harbour Laboratory, said, "We can now use that gene in genetic testing, which will allow growers as well as producers to know exactly what sort of tree they are planting before it produces fruit. It takes a long time for these trees to produce fruit, but by being able to predict exactly what sort of fruit that trees will produce, it will greatly assist growers." The researchers say this could offer a more sustainable form of agriculture. Prof. Martienssen said, "This finding gives us huge hope. We hope to maximize land usage and produce a lot more on the same amount of land, because we do not want to destroy the rainforest any more." However, the environmental group WWF-UK said that the global demand for oil palm was growing rapidly, making the expansion of plantations inevitable. Adam Harrison, the organization's food and agriculture policy officer, said, "In a sense it does not matter if a 'good' variety replaces forest or a 'bad' one, the wildlife and communities that need access to that land will suffer. So for palm oil to be sustainable, the process of allocating land needs to be controlled. There is an abundance of low-carbon, low-wildlife and conflict-free land available and there is no more need for forest... Options: A The more oily palms easily died of bad weather. B The more oily palms can change to the less oily ones. C They don't have enough land to grow oil palms. D They are unable to predict exactly what sort of fruit the trees they are planting will produce. Answer: B The more oily palms can change to the less oily ones. Question:

A: What difficulty are the oil palm growers faced with?

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: All of us have taken an instant dislike to someone, and then felt guilty about being too judgmental. But now it seems we should place more trust in our first impressions. Most people can accurately judge a total stranger following a short meeting, according to scientists. And in general, the more confident the people are, the more likely they are to be correct in their assumptions. Jeremy Biesanz, who led a team of researchers from the University of British Columbia, said: "Many important decisions are made after very brief encounters -- which employee to hire, which person to date, which student to accept". Although our first impressions are generally accurate, it is necessary for us to recognize where they may be not good enough. The researchers arranged for two groups of more than 100 people to meet in a meeting. Much like speed-dating, the volunteers spoke to everyone in their group for three minutes each. At the end of each three-minute chat, they were asked to rate each other's personalities, and how well they thought their impressions "would _ someone who knows this person very well". To find out what the person was "really" like, the scientists had his friends and family fill out his personality reports. Generally speaking, the more confident the volunteers felt in accurately rating another's personality, the closer their ratings were to those of the other person's friends and family, the researchers said. However, the participants with the highest accuracy were those who rated themselves moderately accurate -- those highly confident of their judgment were less successful. The scientists concluded that, although we know people are different from each other, a good judge of character knows that in many ways people are mostly alike. For example, almost everyone would prefer being kind to being unfriendly. Therefore, while first impressions can be generally accurate, they are not conclusive in working out whether somebody really is "better" than someone else. Options: A We should not doubt our ability to judge others. B Our first impressions on a stranger are usually accurate. C Confidence determines whether people can succeed or not. D It's an important task to make a good judgment about strangers. Answer: B Our first impressions on a stranger are usually accurate. Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: You are walking along a lane and never know what you will find. It might be a shop selling oil paintings, or a place where you can buy Dutch cheese. One thing is for sure, you will end up by a canal. Welcome to Amsterdam, the capital of the Netherlands. The year 2013 will be a good time to explore Amsterdam as the city has a lot to celebrate: the famous canal ring will turn 400 years old. Amsterdam will also celebrate the 160th birthday of Dutch painter of the Van Gogh museum, home to the biggest collection of the artist's colorful works. The famous canal ring is a trademark of the city. With more than 100 kilometers of canals, it is no wonder that Amsterdam is called the 'Venice of the north'. But unlike the Italian town, where boats were originally used for transport, the canals in Amsterdam were mainly used for defense in the 17th century. Today ferries on canals offer a different way to explore the city. But to truly experience Amsterdam, you can't miss the city's historic museums and monuments, among which Van Gogh museum is the most famous one. It holds 200 paintings, 700 letters and 500 drawings by the artist. Another famous museum is Anne Frank's house. Anne Frank became famous around the world because of a diary she left explaining her and her family's experience as a Jewish girl during World War II, hiding out in a house hoping that she would not be captured by German Nazis. Amsterdam is small enough to walk or cycle almost anywhere, but it is rarely dull. Best of all it combines its glittering past with a rebellious edginess. Options: A that can be explored by foot B that is completely built on water C that has two historic museums in all D that is famous for its modernization Answer: A that can be explored by foot Question:
