[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: It is easy for us to tell who our family members are, but do plants recognize their own family? Some do, scientists say, according to a report by Science News in early 2010. Guillermo P. Murphy and Susan Dudley are two plant scientists from McMaster University in Hamilton, Canada. They did a few experiments with Jewelweeds, a kind of flower that grows in wet, shady spots. They found that the flowers seem to know their own flower family. In their experiments, Murphy and Dudley planted jewelweeds in pots with either _ or strangers. When jewelweeds were planted in pots with strangers, the plants started to grow more leaves than if they had been planted alone. This response suggests that plants are competing with strangers for sunlight, since a plant with more leaves can receive more light and make more food. Jewelweeds usually grow in the shade, where sunlight is not enough. When jewelweed seedlings were planted with siblings, they grew a few more branches than they usually would if they were alone - but they did not start growing lots of extra leaves. This behavior suggests the plants are more likely to share resources, rather than compete. According to the Science News report, Jewelweeds are not the first plants that plant scientists have studied for family recognition. In 2007, Dudley and her team studied the Great Lakes sea rocket, a plant that grows on the beach - where it may be hard to get fresh water. In that experiment, the scientists found that when sea rockets were planted with siblings, they tolerated each other. But when they were planted with strangers, the sea rockets reacted by working extra hard to grow lots of roots. Dudley says this just because sea rockets, on the beach, get plenty of sun but struggle for water - so when they're threatened, they compete for water. Jewelweeds have plenty of water but have to compete for sunshine, so they grow more leaves. Options: A make a comparison B introduce a topic C describe a pretty flower D build a new theory Answer: B introduce a topic Question:

[A]: In the text, the writer mentioned the experiments of Jewelweeds to _ .

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Not long ago, the only time you could see a robot was when you were reading a novel or watching a movie such asStar Wars . Today, however, a lot of things in science stories have been science facts. Robots are starting to appear in our everyday lives. These robots have different sizes, shapes, and colors. But they all have the same type of man-made "brain". Leading the robot revolution are industrial robots that work in factories. Industrial robots can do different kinds of jobs that are often boring and sometimes dangerous. Robots are also coming to American homes, though not as quickly as they are entering factories. These robots aren't as friendly and bright as those you saw in Star Wars.But, their makers say, today's home robots "walk", sense objects in their way (and sometimes knock into them), and even carry objects (which they sometimes drop). Well, nobody is perfect. We may laugh at home robot today, but some day they may see and hear better than humans do. We humans can only see certain wavelengths of light, and hear certain sounds. That's because the abilities of our eyes and ears are limited. Robots, however, need not have the same limits as we have. Robot may also be equipped with devices that pick up information humans can't. To understand what their sensing devices pick up is a hard job. Remember, man--made brains handle information, including all kinds of data, as zeroes and ones. Imagine the difficulty in trying to explain to a robot what a football looks like--using only zeroes and ones. Options: A science and technology are developing fast B people are interested in new inventions C machines are more capable than humans D robots can be very interesting Answer: A science and technology are developing fast Question:

[A]: The development of robots suggests that _ .

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Once upon a time, there were two seeds . They were good friends. They often talked with each other when they were free. One day, they had nothing to do . They lay on the ground. They looked up at the sky and had a chat with each other. The first seed said, "I want to grow! Then I can enjoy the sun and the rain!" Later, it grew. It had a chance to enjoy the sun and the rain. The second seed said, "I am afraid of growing up. If I grow, I have to live in the _ . Little animals may come up to me and eat me. How terrible! If I become a beautiful flower, a child will come and pick me. It is much better for me to wait. It's a dangerous way to be alive." It did nothing and refused to grow. Spring came soon. A duck came up to the seeds. It eat the second seed and went away. See? We shouldn't act like the second seed. We should face our life bravely. Options: A one B two C three D four Answer: B two Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: "Millions of young people will lose their hearing in five years if they listen to MP3 or MP4 players at a too high voice every day," scientists say recently. Do you often listen to MP3 players at a too high voice? Are you frightened to hear this? The sizes of MP3 players are very small, but small MP3 players make it easy to take hundreds of songs with you. So many young people carry them and listen to music every day. MP3 players are very popular among students. The scientists say teenagers should be far from high volume , including mobile phones' noise. A study says, "High volume and long listening time can cause hearing problems." They think if young people listen at more than 89 decibels every day, they will lose their hearing in five years. A scientist said, "So many young people often use personal music players and mobile phones at a high voice. I am afraid that _ may be losing their hearing. So let's turn our MP3 players down! Options: A Scientists tell young people to turn off their MP3 players. B Teenagers will lose their hearing if they listen to hundreds of songs in MP3 players. C A person will lose hearing in 5 years if he or she listens to an MP3 player every day. D The mobile phone can also cause hearing problems if we don't use it correctly. Answer: D The mobile phone can also cause hearing problems if we don't use it correctly. Question:
