Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Renata Di Pietro was studying to be an opera singer. But at 23, while on a music scholarship at the University of Iowa in 1976, her sight began to fail. Soon, it became increasingly difficult to read scores and pick up hand signals from conductors, and the gifted singer was forced to drop out. After moving to Cleveland, Georgia in 2005, Di Pietro relied on guide dogs to get around. Over the years, she became depressed when she'd lose one of the dogs, who had become her best friend, to old age or death. "It's very painful, because you love each one," she says. In 2009, Di Pietro was _ by information from a friend that miniature horses typically live for at least 30 years and make calm and strong guides. She started with a male horse, but he was too hard to control. Angel came next, a mini white female horse Di Pietro has mostly trained herself. "Horses have the ability to avoid the things in the way," she says. "If I am about to run into something, she slides her body in front of me." Di Pietro, now 59, has taught her guide horse to make some sounds with her hoof when she comes to stairs. "Angel can find a chair and locate the nearest door for me," Di Pietro says. Currently, she's training Angel to pull her wheelchair and to fetch. Despite her disability, Di Pietro still sings, performing with her husband, musician Carl Hummer, at special events. Angel is always by her side. "I fight a battle every day to take courage to engage the world," Di Pietro says. "Angel is my warhorse. We fight that battle together." Options: A She disliked her major in music. B She failed to get high scores. C She couldn't understand hand signals from conductors. D She found it difficult to see things clearly. Answer: D She found it difficult to see things clearly. Question:

The answer is:
Why did Di Pietro have to give up her studying in the university?

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: We know more about the surface of the planet Mars than we know about what is at the bottom of Earth's oceans. Until recently, scientists had mapped only about 20 percent of the sea floor. But our knowledge of the deep seas is changing because of information from satellites. Scientists have produced a new map that provides a detailed picture of the oceans. The map is expected to help oceanographers, industry and governments. The new map is twice as detailed as the map made 20 years ago. David Sandwell is a geophysics professor at the Scripps Institution of Oceanography at the University of California. He and other scientists worked on the mapping project. He says they turned to space to look deeper into the ocean. He spoke to VOA on SKYPE. "The way we're doing that is to use a satellite altimeter , a radar to map the topography of the ocean surface. Now that seems sort of strange that you'd map the topography of the ocean surface when you really want to get at the sea floor. But, the ocean surface topography has these bumps and dips due to gravitational effects that mimic what's on the sea floor." The scientists collected and studied information from two satellites. Some of the data came from the European Space Agency's Cryo-2 satellite. It was placed in Earth's orbit to watch sea ice. The other satellite is the American space agency's Jason-1. It is studying the surface of the oceans. Scientists combined the satellite data with images gathered by sonar equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed. "That enables us to look at smaller-scale features and also features that are buried by sediments in the ocean basins." The new map shows the sea floor as it has never been seen before. It shows thousands of underwater mountains and places where continents pulled apart. It shows where earthquakes were active many years ago. They all are buried deep underneath the ocean floor. In one place, three mountain ridges join at the... Options: A be an advertisement B appear on VOA C make a comment on radar D appear on SKYPE Answer: B appear on VOA Question:???

Write a multi-choice question for the following article, with the given choices and answer: Article: Most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it's a chance in million. People have made a census ( ) to colors of more than four thousand kinds of flowers and discovered that only eight of them are black. As we know, sunlight is formed by seven different colored lights. The wave length of each light is different, so the quantity of heat in each light is also different. Flowers, especially their petals ( ) , are easy to be harmed by high temperature. Black flowers can take in all the light waves which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat. Options: A impossible B seldom C common D no chance Answer: B seldom Question:
----
Answer: It is _ to see a black flower.

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: It is reported that conservation groups in North America have been arguing about the benefits and dangers of wolves. Some groups believe wolves should be killed. Other people believe wolves must be protected so that they will not disappear from the wilderness For Killing Wolves In Alaska,the wolf almost disappeared a few years ago,because hunters were killing hundreds of them for sport. However.1aws were established to protect the wolves from sportsmen and people who catch the animals for their fur.So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply. A wolf naturally eats animals in the deer family. People in the wilderness also hunt deer for food.Many of the animals have been destroyed by the very cold winters recently and by changes in the wilderness plant life.When the deer can't find enough food,they die. If the wolves continue to kill large numbers of deer,their prey will disappear some day.And the wolves will.too.So we must change the cycle of life in the wilderness to balance the ecology.If we killed more wolves,we would save them and their prey from dying out.We'd also save some farm animals. In another northern state,wolves attack cows and chickens for food.Farmers want the government to send biologists to study the problem.They believe it necessary to kill wolves in some areas and to protect them in places where there is a small wolf population. Against Killing Wolves If you had lived long ago,you would have heard many different stories about the dangerous wolf.According to most stories,hungry wolves often kill people for food.Even today,the stories of the "big bad wolf'"will not disappear. But the fact is wolves are afraid of people.and they seldom travel in areas where there is a human smell.When wolves eat other animals,they usually kill the very young.or the sick and injured .The strongest survive .No kind of animal would have survived through the centuries if the weak members had lived.And has always been a law of... Options: A they never eat strong and healthy ones B they always go against the law of nature C they might help this kind of animals survive in nature D they disturb the ecological balance in the wilderness Answer: C they might help this kind of animals survive in nature Question:

Answer:
According to those against killing wolves,when wolves eat other animals, _ .
