Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Plants have family values, too; it seems, with new research suggesting they can recognize close relatives in order to work together. An ability to tell family from strangers is well known in animals, allowing them to cooperate and share resources, but plants may possess similar social skills, scientists believe. Susan Dudley and Amanda File of McMaster University in Ontario, Canada, report they have demonstrated for the first time that plants can recognize their kin. This suggests that plants, though lacking recognition and memory, are capable of complex social interactions. "Plants have this kind of hidden but complicated social life," Dudley said. The study found plants from the same species of beach-dwelling wildflower grew aggressively alongside unrelated neighbors but were less competitive when they shared soil with their families. Sea rocket, a North American species, showed stronger and healthier root growth when planted in pots with strangers than when raised with relatives from the same maternal family, the study found. This is an example of kin selection, a behavior common in animals in which closely related individuals take a group approach to succeeding in their environment, the researchers said. Kin selection also applies to competition, because if family members compete less with each other, the group will do better overall. "Everywhere you look, plants are growing right up next to other plants," Dudley said," Usually it's a case of each plant for itself. But sometimes those plants are related, and there are benefits to not wasting resources on being competitive, and there is not really a cost to not being competitive as long as your neighbor is also not being competitive." Learning and memory appear to be important for kin recognition in animals, but this isn't an option for plants, she noted. Some researchers speculate that plants communicate through their roots, identifying themselves using tiny chemical signatures specific to each plant's family. Options: A Plants communicate by using tiny chemical signatures specific to each plant's family. B Plants communicate with each other through their roots. C Plants communicate with each other by their leaves. D Plants communicate with each other with their flowers. Answer: B Plants communicate with each other through their roots. Question:
A: How can the plants communicate with each other according to experts' suppose?

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Creative conservationist Asher Jay is a designer, artist, writer, and activist who is trying to save the world's most threatened wildlife with an unusual weapon: Art. "Today we need everyone's involvement, not just core conservationists," says Jay. " People with no previous interest in conservation tune in to my messages because they engage with my work aesthetically. It starts as an interest in art for art's sake and ends with making lifestyle changes." The New York-based artist has become a visual voice for a range of environmental causes. In Africa, screen savers glow with Jay's graphics of a Poached rhino horn dripping with blood. Jay's cartoons of elephants killed for their tusks have been shown in New York's Times Square, wild other works have spread worldwide on social media. "The right image can overcome language and cultural barriers, connecting with people on a non-verbal, emotional level," she says. "It all starts with making an emotional impression on one person. Only then will someone change habits, speak out, or donate." In recent years, much of Jay's best known work has focused on the illegal ivory trade. In 2012, she created a silk screen print, showing a stark image of an elephant's head silhouetted in black, dripping with red blood, and accented by a tusk decorated with images of elephants' families. "Every tusk costs a life," said accompanying text. "Stop poaching." "I wanted to visualize the scale and brutality of the crisis and use art to tell the blood ivory story," she says. "Every year, 35,000 elephants are slaughtered; that's one every 15 minutes." "Two-thirds of Africa's elephants have been killed for tusks in the last 35 years. If this continues, experts predict elephants in the wild will be extinct in less than ten years." Much of Jay's work around poaching aims simply to correct a widespread misunderstanding. "Many people think an elephant's tusk or a rhino's horn simply falls off, like losing a tooth. My goal," she says, "is to make them understand that elephants die painful... Options: A An artist's animal work aims to stop animal slaughter. B The risk of extinction for wild animals in Jay's works. C A new way to stop illegal trade designed by an artist. D How people hunt and abuse wild animals. Answer: A An artist's animal work aims to stop animal slaughter. Question:
Answer: What is this passage mainly about?

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Peter and his seven-year-old sister ,Kate , were at the same school. Not long after his tenth birthday Peter was entrusted to take her to school. It was only two stops down the road , but the way his parents kept going on about it , you might have thought Peter was taking Kate to the North Pole . He was given instructions the night before. When he woke up , he had to listen to them over and over again. He was to keep hold of Kate's hand at all times , sit close to the front nearest the window , and tell the bus driver the name of his stop. Peter repeated all this back to his mother and set out for the bus stop with his sister. They held hands all the way. Actually he didn't mind this but simply hoped that none of his friends would see him holding a girl's hand. The bus came. They got on and sat close to the front. It was ridiculous sitting there holding hands and there were some boys from school there, so they let go of each other. Peter was feeling proud of himself. He could take care of his sister anywhere. If they were alone tighter on a mountain pass and came face to face with a pack of hungry wolves, he could know exactly what to do. Taking care and not to make sudden movement, he would move away with Kate until they had their backs to a large rock. That way the wolves would not be able to surround them. Then he takes from his pocket two important things--his hunting knife and a box of matches. He takes the knife from its sheath and sets it down on the grass, ready in case the wolves attack. They're coming close now. They're so hungry and are watering and growling . Kate is crying, but he cannot comfort her. He knows he has to concentrate on his plan. Right at their feet are some dry leaves and twigs. Quickly and skillfully, Peter gathers them into a small pile. The wolves are edging closer. He has to get this right. There's only one match left in the box. He bends down, cups his hand and lights the match. There's strong rush of wind. The flame flickers, but Peter holds it close to the pile and then... Options: A Peter and Kate let go of each other B Peter was told instructions twice C Peter recited the instructions to his mother D Peter managed to avoid meeting his friends Answer: C Peter recited the instructions to his mother Question:
Answer:
