Write a multi-choice question for the following article, with the given choices and answer: Article: My son and I were trying to sell the house we had repaired, but in the barn there were bats and they would not leave. The barn was their home. They told us so in their own way they hung for the season. "Don't worry about it, Dad." Patrick said. "They keep down the mosquitoes ." Unfortunately they also kept the buyers away. When we had asked a person to sell the house for us he had refused to show it because of the bats. "Bats are popular," Patrick comforted me. "They are ecological." "Isn't there a machine you can buy that produces high-frequency sounds to keep bats away?" " I don't know," said Patrick. "But I like bats, and whoever buys this house will probably like them too.' "Probably?" I hated that word. "How many bats are there, anyway?" "I counted about 90 last night," said Patrick. "They were dropping out from under the edge of the roof." "You mean there are more------outside?" "They're everywhere, Dad. But look at it this way. When the cold weather comes, they'll be off to Mexico. Maybe in the spring we can keep them out. Don't worry about it," he said for the the hundredth time. "It's not a problem." The bat expert I called was even more active than Patrick. "I think you've got a large number there," he said in wonder. "I've been trying to attract bats to our house for 25 years. A single bat ears up his weight in mosquitoes and black flies three times every night. You've a very lucky man." I offered to share my luck with him. He could take them away. "Bats have a remarkable homing instinct ," he said. "They'd fly straight back even if I transported them 100 miles. Once they have settled, you can't stop them from coming back." I was silent. Finally we managed to rent the house to a young family, who were also interested in buying it. "What about the bats?" I said to Patrick. "Oh, they love the bats," he said. "No mosquitoes. No black flies. It's one of the things that attracted them." "Do you think they will really buy the house?" "Probably? Well, if they do, I suppose I'll have to admit that I was...

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Where we live, on the eastern shore of Maryland, the gentle waters run in and out like fingers slimming at the tips. The Canada geese know this place, as do the white swans and ducks. In the autumn, they come home for the winter. Once or twice each year, snow and frozen rain move into the area. When this happens, if the river is at its narrowest, there is a freeze which hardens the water to the ice. One morning, a friend of mine set the breakfast table beside the huge window, which overlooked the Tred Avon River. Suddenly she leaned forward and cried out, "There is a goose out there." We saw the figure of a large Canada goose, very iii, its wings folded tight to its sides, its feet frozen to the ice. Then from the dark sky, she saw a line of swans. They floated from the top of the sky downward and at last landed on the ice. My friend was on her feet now, with one unbelieving hand against her mouth. As the swans surrounded the frozen goose, she feared what life it still had might be pecked out by those great swan beaks. Instead, those beaks began to work on the ice. The long necks were lifted and curved down, again and again. It went on for a long time. At last, the goose's head lifted. Its body pulled. Then the goose was free and standing on the ice. And the swans stood in the air watching. Then, as if it had cried, "I cannot fly," four of the swans came down around it. Their powerful beaks chipped off the ice and held in the feathers. Slowly, the goose spread its wings as far as they could go, and moved slowly into the sky. This is a true story. I just think of it in the bad moments, and from it comes only one hopeful question:" If so for birds, why not for man?" Options: A They chipped off the ice held in its feathers. B They waited patiently for the ice held in its feathers to melt. C They came down and lifted it up to the sky together. D They stayed with it and protected it. Answer: A They chipped off the ice held in its feathers. Question:
A: What did the swans do when they saw the Canada goose couldn't fly?
