Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Health officials in Canada are very busy these days. They are placing chickens at fixed points all along their 2,500 km border with the United States of America. It's not a joke, nor have the Canadians gone mad. They are using these chickens to see if the West Nile virus is still around. The virus infects birds, so the chickens have a chance of catching the virus and fall ill. The West Nile virus is spread among humans. It killed seven people in New York last year. Countries around the world are realizing that it may just be possible to stop certain kinds of people from entering their land. However, it is very difficult to stop viruses traveling from one end of the earth to another. When they travel to new places, they get used to the environment very easily and sometimes start destroying the local plant and animal life. These biological polluters are called smart polluters. These smart polluters can be carried across borders of countries unknowingly. Just as we humans are travelling across the world more often than earlier, these biological polluters have also started journey much more. They slide into airplanes through their wheels. They dig into objects that travelers may be carrying from one country to another. There are some good examples of how these polluters work. The water hyacinth of South America is blocking lakes in China and Africa. Tree snakes from Papua New Guinea are busy eating up some birds in the country of Guam, which breaks its natural balance. That's why the customs officials in many foreign countries prevent people from bringing in a small plant, or an object made of wood that is in its natural form. The customs officials have these rules because these varieties of plants are special to certain places. The plants have the power to spread new illnesses among native plants and animals. Biological polluters always create problems in places where they do not belong. They could be special varieties of plants, bugs or even animals. Options: A Land Pollution B The West Nile Virus C Smart Polluters D The Water Hyacinth Answer: C Smart Polluters Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: The worker I hired to repair my house had just finished a difficult first day on the job. A broken wheel made him an hour late; his ladder( )fell down when he was painting the roof and now his old truck wouldn't start. With each problem he shouted angrily more at himself than at his things. As I drove him home, the man didn't say a word. I tried talking to the man to kill time. I managed to find out that he had come up from Blue Hills in Victoria with his family six months ago to find a job. This was his first job since moving here. I now knew why his price was lower than any other worker I could find in the local newspaper. He really needed the job. His clothes told me as much. On arriving, much to my surprise, he invited me to meet his family. As we walked through his front garden he suddenly stopped at a small tree and placed his hands on it. Then , when he opened the door he completely changed. Instead of his troubled face, there was now a warm smile, hugs for his two children and a kiss for his wife. The following day, I asked him about the tree. "That's my trouble tree," he answered. "Work troubles aren't welcome at home with my wife and children. So I hang them on that tree every night when I come home. Then in the morning I pick them up again." "And you know what else?" he said smiling, "The next morning I find that there aren't as many as I remember hanging up the night before." Options: A To get good luck. B To leave his trouble outside. C To send good wishes to his family. D To clean his hands. Answer: B To leave his trouble outside. Question:
