input question: Write a multi-choice question for the following article: Article: As a young man, Paul Beier hiked in the mountains of California. Since then, he has decided to choose his career as a wildlife protector. He went to school to learn more first of all. After he earned his doctor's degree, he eagerly signed up for a job studying cougars , which once lived throughout the United States, but now live mainly in the Rocky Mountains and westward. They need not only a lot of land to survive but also plenty of food and places to raise their young. But many wild areas have been divided by freeways and taken over by towns. The small wilderness areas of the Santa Ana Mountains in Southern California didn't have much room for them. And yet a few still lived there. How did they do it? Many big animals are disappearing. Those that survive are being trapped in shrinking patches of habitat. A patch may not have enough space or food for a cougar to survive. Scientists wondered if cougars could move from one patch to another. If so, maybe humans could preserve wildlife corridors to connect the patches, providing enough room for the animals. But no one had shown that animals use wildlife corridors in real life. To see if cougars had found corridors through local suburbs and freeways, Paul and his research team studied 32 cougars for five years. They used a drug to make each cat sleep, buckled a radio collar around its neck, and let it go. Every day, Paul used an electrical device that sends and receives radio signals to find cougars, listening for radio beeps from their collars. Once or twice a week, he trailed one of the cougars all night. He traced their travels on a map. Sure enough, some of them had discovered paths from one small park land to the next. One cougar became famous for his travels. He was named M6:"M"for Male, and"6"because he was the sixth one collared in the study. M6's corner of the Santa Ana Mountains wasn't large enough for him. Chino Hills State Park was not far away, but the trip was not safe. After dark, M6 used a paved vehicle underground passage to cross undera busy...???
output answer: Question: Scientists guess cougars could survive in the Santa Ana Mountains mainly because .Options:A they found plenty of food thereB their living areas weren't divided by freewaysC nobody disturbed them when they raised their babiesD they succeeded in finding more food and places to surviveAnswer:D

input question: Write a multi-choice question for the following article: Article: The cattle egret has lived in American continent in recent years. Non-native species are a worldwide problem and studies are devoted to assess the damage they cause to local species populations. The cattle egret primarily lives on the grassland and feeds in close association with animals like cattle and sheep. This bird is native to Africa, southern Europe and western Asia. The cattle egret in Brazil is unlike a number of bird species that have been established and expanded to non-native areas through human assistance. The first sight of the cattle egret in the New World were reported between 1877 and 1882, followed by sightings in British Guiana and Colombia and later expansion throughout the Americas. In Brazil, the cattle egret was first recorded in the northern region of the country in 1964, feeding along with buffalos on Marajo Island in the state of Para. While the cattle egret is not currently a threat to native animals and birds in Brazil throughout most of its geographic distribution, it has the potential to produce bad effects, as evidenced by its occupation of island environments. For example, in the Fernando de Noronha archipelago, the cattle egret drives adult native seabirds away from their nests in producing time. Understanding how the cattle egret settled and lived in Brazil is important for the better understanding of spreading patterns of bird populations and their interaction with the local species. Explaining the egret cattle's settling in the Americas is a challenging task due to the lack of sufficient information and reports on entrance time, location, and number of events. Comparisons between native and non-native populations can provide a 'natural' experimental way to clarify the biological and environmental factors that may contribute to range expansion and adaptation to climate change, and to find how animals respond to strange and sudden ecological and environmental pressures.???

input question: Write a multi-choice question for the following article: Article: Over the next 20 years, we are going to send more and better robots to Mars. Those robots will send back better pictures, maps, samples, and weather reports. There is a limit to what robots can tell us, though, so eventually we will have to send people to study the planet. Before people can visit Mars, we need to invent a spaceship that can take us there. Mars is very far away. Depending on where Mars and Earth are in their orbits around the sun, it could take between six months to a year to get there. The moon is much closer, and we were there, 25 years ago. Over the next 10 years, we are going to work on building a new spacecraft that can go to the moon. Using this craft, we will practice the skills we need to go to Mars. Once we return to the moon, we are going to build a station so that people can live and work on the moon for months at a time. This is important so that we have a place to start from when we want to visit Mars, but it is also important because it gives us practice with living away from Earth. By the time you are old enough to be an astronaut, we will have people spending months on the moon. By the time you are old enough to be a commander of a space mission, we will be taking trips to Mars. By the time your kids are old enough to be astronauts, we may have people living on Mars. Wouldn't it be cool to get a postcard from someone who was building a house on Mars? Wouldn't it be cooler if it was you who sent the postcard????
output answer:
Question: A space station on the moon is important because _ .Options:A it gives us experience with living on other planetsB people can plant crops in itC the new spacecraft can only land in itD it is a place for astronauts to have funAnswer:A
