input question: Write a multi-choice question for the following article: Article: Can a fish hear fishermen moving along the stream? What are the facts about the ability of a fish to see? Can they tell the difference between colors? The sharp hearing of a fish has been proved by two scientists, who trained a fish to expect its food when it heard the sound of a whistle. And a slight sound two hundred feet away could drive fishes away. That should make fishermen start thinking. One scientist had made experiments to prove fish can recognize different colors such as red, brown, yellow and green. Fish also have an eye for different shapes. One scientist proved this by teaching fish to connect certain patterns with food. He used a small circle and a square. If the fish swam towards the circle, they received food as a reward. If they swam towards the square, they received nothing. The fish learned in time to go to the circle but not to the square. Does this mean that in time fish might learn to leave alone all food on hooks that they have seen often before? Here is something for all fishermen to think about! These facts help to make more believable some of the "believe it or not" stories that have been told about fish. It is clear that fish have sometimes shown their ability to gain knowledge as man does. A good example of what we might call "thinking" by a fish is given by an experience of Dr. Andrew Gage. Fishing over a bridge, he hooked a fish. It struggled and dragged the line two hundred feet away before he stopped it. Then it swam back to the bridge. The clever fish then swam round a pile and, with a sudden push, broke the line. If the story ended there, one could say that the fish had freed itself by chance. However, Gage went on fishing. Below him he could see the fish that had broken loose. After another twenty minutes the fish again seized the food on the hook. This time it did not swim out but swam round one of the piles and again broke the line. Many stories are told of the fish that get away and the clever "old hand" ones that can't be caught. The more often a fish is nearly caught,...???

Write a multi-choice question for the following article: Article: I live in a very over populated beach area in the Los Angeles, and I love the beautiful scenery! But because of many people, lots of things are easy to be out of order, and sometimes it's also easy to _ . Today was a day I wish I did not get out of bed. I mean that if I did not have to wake up and deal with all the things that I deal with on a daily basis, it would have been wonderful. I had a cup of coffee this morning and that was my meal for breakfast, not healthy I know. Anyway, my stomach was sounding like a truck. So, I jumped in my car and decided to buy some food. I was in line at Taco Bell and the line was like a long snake! Finally I got to place my order, but a young girl in nice clothes pulled in and was stuck in such a way that unless I moved for her, she wouldn't be able to get out. So I backed up and waved her into my place in the front of the line. To my surprise, this young girl did not say thanks. I was cool with it because I thought that I had done something nice for a change. After the girl received her food and pulled away, I pulled into the ordering spot, not mad, but hungry, and the employee said, "Hi, that girl just paid for your food." That food was the most satisfying nourishment my body had ever taken! If just by chance you are that person who bought my food, I should say "Thank you!"

Q: Write a multi-choice question for the following article: Article: For a 400-year-old art form, opera had a bad fame: overweight actresses singing the words which were hard to understand in one of those romance languages you were supposed to learn in high school. And with tickets costing as much as $145 a performance, opera goers also had a certain appearance in people's mind: rich, well-dressed and old.[:] But now opera companies around the country are loosening their ties and kicking off their shoes in an attempt to keep opera alive and take it to a younger and not so wealthy audience. Opera producers have found that to attract this crowd, they need to make the opera closer to common people. Because young people don't or won't come to the opera, companies are bringing the opera to them, giving performances in such unusual places as parks, libraries and public schools. The Houston Grand Opera's choice is the public library, where it performs "mobile operas" shortened versions of child-friendly operas. This summer's production is Hansel & Gretel. By performing smaller versions of large productions, producers are able to make people interested while keeping costs at a reasonable level. The San Francisco Opera, which will be celebrating its 75th anniversary this year, is staging Cinderella free of charge, keeping costs down by employing students from its Young Artists' Training Program.
A: Question: Opera companies prefer to perform short versions because _ .Options:A they can be performed in public librariesB short versions are easy to performC it is hard to find long versionsD they can make more people come to operaAnswer:D

Problem: Given the question: Write a multi-choice question for the following article: Article: Many science fiction stories tell about explorers arriving in a new world. The explorers then use some kind of high-tech device to test for breathable air or signs of life. But here on Earth, science fiction is becoming reality through a new sampling technology called environmental DNA, or e-DNA for short. Scientists can use it to identify rare or invasive species, study bio-diversity or estimate fish populations with just a little air or water. Ryan Kelly is an ecologist at the School of Marine and Environmental Affairs at the University of Washington in Seattle. He works in a laboratory there with other researchers. They study the genetic material released by living creatures. "Essentially we can take a sample of soil or air -- and in our case -- water, and we can sequence(to arrange the order of genes)the DNA out of it and tell you what is there." Ryan Kelly says he and his research team are studying water samples collected from Puget Sound. He says the cost of gene sequencing has "been reduced greatly in recent years." That makes DNA testing more widely available. Environmental DNA can be used in two ways. One is to identify the creatures that live in a certain place. The other is to confirm the presence or lack of a specific creature. Caren Goldberg heads the new e-DNA lab at Washington State University in Pullman, Washington. She is one of the first biologists in the northwestern United States to take the technology from the testing phase to actually using it. "It is extremely useful for species that are really hard to find. I have spent many hours looking for species that I was pretty sure were there -- looking under rocks, looking in water, doing all kinds of surveys." Caren Goldberg sees e-DNA as a way to get answers more efficiently, safely and with less destruction compared to traditional survey techniques. Until recently, scientists depended on diving deep, netting or using an electric current to temporarily catch fish. "We're absolutely at this point where proof-of-concept has been established. I...
