Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Fencing or Not Wildlife fences are constructed for a variety of reasons including to prevent the spread of diseases, to protect wildlife from poachers , and to help manage small populations of threatened species. Human-wildlife conflict is another common reason for building fences. Wildlife can damage valuable farm animals and crops. Some species carry diseases of agricultural concern, and a few threaten human lives. At the same time, people kill wild animals for food, trade, or to defend lives or property, and human activities destroy wildlife habitat . Separating people and wildlife by fencing can appear to be a _ beneficial way to avoid such harmful effects. But in a paper in the journal Science, published recently, some scientists argue that fencing should only be used if worse comes to worst. According to the scientists, although fencing can have conservation benefits, it also has costs. When areas of wildlife habitat are changed into islands, the resulting small and isolated populations tend towards extinction, and the resulting loss of larger-bodied species can affect interactions between species in ways that cause further local extinctions. Therefore, scientists are asking that conservationists carefully weigh up the biodiversity costs and benefits of new and existing fences. In addition to fences' ecosystem-wide impact, the scientists don't think they always achieve their specific aims. Construction of fences to reduce human-wildlife conflict has been successful in some places but the challenges of appropriate fence design, location, construction, and protection mean that fences often fail to deliver the anticipated benefits. In some places, fences also provide poachers with a ready supply of wire for making traps. A variety of alternative approaches, including better caring for farm animals, community-based crop-guarding, insurance and wildlife-sensitive land-use planning are suggested to reduce conflicts between people and wildlife without the need for fencing.

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: When I wake up on summer mornings, I know I am going to my favorite place to volunteer and make a difference in someone's life just by being with him or her -- a summer school for autistic children. By helping the kids read or do math, I am not only teaching important skills but also helping them feel like any other kid. There are many wrong ideas about autism. The kids I work with can think and feel. They need help only in certain areas. Of course, each kid is special. For example, some kids like to draw, and others like to sing. At the school, the kids learn through about 20 activities. These activities can help them learn skills they will need later in life. The very first day I volunteered, a boy came up to me, put his hand on my shoulder, and said "Hello". From then on, I knew I could make a difference. Another boy loved to have me read books that can help him learn to read. Sometimes he could be encouraged to read a few words or sentences. Finally, one day during reading practice, he read nearly 220 words himself! Summer school is also a time for fun, Last summer, bagpipe players came to perform. Most of us had our hands over our ears because they were so loud. When they asked for a volunteer from the audience, one girl raised her hand as high as she could, got up on stage, and even tried the bagpipes in front of everyone. Through these experiences, I realize that the challenges these kids face do not stop them from doing many amazing things. I'm teaching them, but they are teaching me more.
