input: Please answer the following: 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....

output: Question: Why is the Ivanpah Solar Electric Generating System being built in the desert?Options:A Because the temperature is extremely high in the desert.B Because there is no life in the desert.C Because there is much salt in the desert.D Because sunlight is highly focused in the desert.Answer:D

Please answer this: Write a multi-choice question for the following article: Article: Christopher Columbus was born in Genoa, Italy. He was the oldest of five children in his family. His father was a wool weaver. He helped his father with the weaving, but he always wanted to sail the seas. He didn't get to school very much, but he learned to read and write Spanish during his travels. He also taught himself Latin because all the geography books were written in Latin. Some people thought he was trying to prove the world was round, but this is not true. He wanted to find a short way to get to the Indies by ship. He was a Christian and wanted to tell the story of Christ to the people he would find in the far-away lands. He also wanted wealth for himself and for Spain, and he wanted to be famous. He tried for eight years to get King Ferdinand and Queen Isabella to supply him with ships and money. They left Spain on August 3, 1492 and sailed toward the west. After many days, the sailors had covered a long distance on the sea and were ready to turn around for home when they saw land, an island Columbus named San Salvador. He thought he had found the Indies and called the people he saw there "Indians". When they got to Cuba, he thought he was in Japan. The world was a lot larger than he thought. On Christmas Eve, the Santa Maria was wrecked near Haiti. Columbus built a fort and left 40 men to hunt for gold. Then he returned to Spain on the Nina. The people of Spain welcomed him as a hero. He made three more voyages across the ocean. His 13-year-old son, Ferdinand, went with him on the fourth voyage. Columbus did not become rich as he had hoped. At the end of his life he only had a pension the king and the queen had given him because he was the first to reach the New World. He spent the last few months of his life in bed because of the pain of arthritis . Columbus not only discovered a New World, but he led the way for other explorers.

input question: Write a multi-choice question for the following article: Article: Jeremy Kerr, a researcher at the University of Ottawa in Canada, and his colleagues analyzed more than 400,000 observations of bumblebee species collected in North America and Europe from 1975 to 2010. When the researchers recorded the locations of these bee populations, they found that many of the 67 species analyzed were moving northward from their southern limits while the northern edges of the bees' ranges are staying in place. What it results in is obvious. Bees have been paid more attention to in recent years, with populations of honeybees and bumblebees obviously declining in some parts of Europe. Previously, attention on the decline of bee populations has focused on causes including habitat loss, pesticide use and the spread of bee parasites . But the work by Kerr's team found something different. "For every species, there is one or two species declining and others that are not moving at all," says Kerr. This shift has also been observed in other species, such as butterflies. But due to a new cause -- the rise of temperatures instead of total pesticide use, a change in land use or parasites, bumblebees -- unlike butterflies -- have failed to extend the northern boundaries of their ranges into the territory that is now habitable for them, so bumblebee species across Europe and North America are declining rapidly, the latest study led by Kerr's team finds. "Our data suggest that the new factor plays a leading, or perhaps the leading, role in this trend," says Kerr. "This study shows that a fourth factor is also beginning to affect it. It is likely that the combined stresses from all of these pressures will have destructive impacts on bumblebees in the not-too-distant future," says Dave Goulson, a bee researcher at the University of Sussex, Brighton, UK. Exactly what can be done to help bumblebees is not clear. Kerr's team suggests that relocating colonies might be an answer but Goulson says that because the insects are mobile they are capable of moving northwards if there is suitable habitat available.???
output answer:
Question: Which statement may Goulson agree with?Options:A Relocating bumblebees isn't much good.B The findings of Kerr's study are doubtful.C The future of bumblebees is still promising.D Knowing bumblebees' living habits is the most urgent.Answer:A
