Problem: Given the question: Write a multi-choice question for the following article: Article: Wildlife conservationists in Kenya are trying to save a rare kind of rhinoceros .Somanynorthernwhiterhinoshavebeenhuntedandkilled that they are almost dying out. There were only five northern white rhinos left. So the workers hoped they could save the rhinos by helping them produce young. Three northern white rhinos lived at The Ol Pejeta Conservancy in Kenya. Workers with military weapons guarded the rhinos as they walked, played and ate over a large area of natural grass and trees. The three rhinos were brought to the conservancy in 2009 from a zoo in the Czech Republic. Workers hoped they would have a better chance of survival in a more natural habitat. But breeding has not been as successful as they had hoped. And the number of northern white rhinos continues to decrease. One of the rhinos at the conservancy died in October. Another died at a zoo in the US city of San Diego, California earlier this month. The San Diego zoo still has one northern white rhino left. The zoo in the Czech Republic also has one. The last wild northern white rhinos were hunted and killed during conflicts in the Democratic Republic of Congo over the past ten years. Rhinos are killed because many people in Asia want the animals'horns .They believe the horns will help with medical problems. But researchers say there is no medicine in the horn, just a kind of hair. The last male northern white rhino is 41 years old. He has been unsuccessful in producing young with a female rhino. So conservationists will use artificial methods to make a young female become pregnant. If that is not successful, they will try to fertilize a northern rhino egg and put it into a southern white rhino, who will act as a surrogate mother. The last solution would be cross-breeding between the northern and southern white rhino species. If cross-breeding is successful, there is hope that some part of the northern white rhino species may still live on.

input question: Write a multi-choice question for the following article: Article: ARE you a dog person or a cat person? With so many photos and videos of cats and dogs doing cute things online, it's easier than ever to answer which of these furry friends you like more. There are many reasons why people prefer one type of pet over the other. So, have you ever wondered what your preference for cats or dogs says about you? In fact, a 2010 study done by Sam Gosling , a psychologist at the University of Texas, US, and his graduate student Carson Sandy found that dog people are more extroverted agreeable and serious than cat people. "Cats will occasionally engage in social activities, but usually after only a few minutes they will abandon the game. Dogs, on the other hand, will often engage in play, like fetching a thrown lull, for hours at a lime," said Modem Dog magazine. Just on the basis of dogs' nature being more sociable than cats', you may expect that the personalities of dog people also reflect higher sociability. And Cosling's study found that dog people are generally about 15 percent more extroverted and 13 percent more agreeable, both of which are associated with social altitude. In addition, dog people are 11 percent more conscientious than cat people. "Conscientiousness" is a tendency In show self-discipline ,to complete tasks and aim for achievement. This quality also shows a preference for planned rather than spontaneous behavior. In comparison, cat people an; about 12 percent more anxious, but they are also 11 percent more "open" than dog people, due to a general appreciation for art, emotion, imagination, curiosity, adventure, unusual ideas and variety of experience. And people high on openness are more likely to hold unconventional beliefs. Despite vast differences, there an some things that cat people and dog people have in common. "Both types of people consider themselves close to nature, dislike animal-print clothing and generally optimists. " noted Mother Nature Network.???
output answer: Question: According to the article, both dog people and cat people _ .Options:A are generally self-disciplinedB are usually positive and care about natureC are likely to hold unconventional beliefsD like to wear animal-print clothing;Answer:B

Please answer this: Write a multi-choice question for the following article: Article: The world's largest solar thermal plant is set to begin producing power in the United States by the end of the year. Wind and energy from the sun are generally considered clean, unlike energy from coal-burning power stations. However, environmentalists now worry that too much solar power development could harm the local environment. A California company -- BrightSource Energy is building a huge solar power plant in the Mojave desert, about 60 kilometers southwest of Las Vegas, Nevada. The plant is known as the Ivanpah Solar Electric Generating System. Joe Desmond works for the company. "This is actually one of the highest concentrations of sunlight in the world, out here in Ivanpah." explained Desmond. BrightSource Energy will deploy 170,000 specially designed mirrors to direct solar energy towards boilers on top of three power towers. The steam produced in the boilers will drive turbine to make electricity. Joe Desmond says the steam can reach temperatures of more than 260 degrees Celsius. "We can store the sun's thermal energy in the form of molten salt, so we can produce electricity even when the sun goes down. There is a lot of interest in concentrating solar power around the globe in environmnents where you have lots of sun, such as China, South Africa, the Middle East, North Africa, explained Desmond. Environmentalists generally support the idea of solar power, however, many are concerned about the effect of power plants on sensitive environment. Lisa Belenky is a lawyer with the Center for Biological Diversity, a private group. She says environmentalists are specifically worried about the effect of the Ivanpah Solar Project on the sensitive plant and animal life in that part of Mojave desert. "Even though the desert seems big, when you start cutting it up, it can really affect how the species and the animals and the plants are able to survive in the long run,"said Lisa Belenky. BrightSource Energy has already spent more than $ 50 million to move endangered desert tortoises away from the power plant....
