Problem: Write a multi-choice question for the following article: Article: Researchers at Sweden's KTH Royal Institute of Technology say they have found further proof that the wolf ancestors of today's dogs can be from southern East Asia -- findings that are contrary to theories placing the birth place in the Middle East. Dr Peter Savolainen, KTH researcher in evolutionary genetics, says a new study released Nov. 23 confirms that an Asian region south of the Yangtze River was the principal and probably the only region where wolves were domesticated by humans. Research data show clearly that dogs are descended from wolves, but there's never been scientific agreement on where in the world the domestication process began. "Our analysis of Y-chromosomal DNA now confirms that wolves were first domesticated in Asia south of Yangtze River -- we call it the ASY region -- in southern China or Southeast Asia," Savolainen says. The Y data supports previous evidence from mitochondrial DNA. "Taken together, the two studies provide very strong evidence that dogs appeared first in the ASY region," Savolainen says. Archaeological data and a genetic study recently published in Nature suggest that dogs originate from the Middle East. But Savolainen rejects that view. "Because none of these studies included samples from the ASY region, evidence from ASY has been overlooked," he says. Peter Savolainen and PhD student Mattias Oskarsson worked with Chinese colleagues to analyse DNA from male dogs around the world. Their study was published in the scientific journal Heredity. Approximately half of the gene pool was universally shared everywhere in the world, while only the ASY region had the entire range of genetic diversity. "This shows that gene pools in all other regions of the world most probably originate from the ASY region," Savolainen says. "Our results confirm that Asia south of the Yangtze River was the most important -- and probably the only -- region for wolf domestication, and that a large number of wolves were domesticated," says Savolainen. In separate research published recently in Ecology...

A: Question: What is special about mitochondrial DNA?Options:A It is only used in studying evolutionary relationships.B It alone can provide hard evidence for Savolainen's research.C It is the most useful in finding out the birth place of dogs.D It comes from the mother of most animals and plants.Answer:D

Problem: Given the question: Write a multi-choice question for the following article: Article: Reading is a great way to improve your English. You'll learn new words, revise previously-taught structures and absorb thousands of useful expressions and phrases... without any effort. By reading, you are receiving valuable language input. And this is how you learn! Remember, language learning is a combination of input + practice. As you're reading, you're taking in language naturally, and you're seeing how it all fits together. This is _ to your learning. The great thing about reading is that learning takes place subconsciously. There are no exercises to do, no grammar rules to learn, no tasks to complete... it's all natural. The language flows in through your eyes, and gets recorded in your brain. What could be easier? The key to effective reading is to read things that you want to read. There are millions of books, magazines and websites out there. You couldn't possibly read them all. So, the important thing is to find things that you like reading. Then, you'll be motivated to read. And then the reading won't be difficult. It'll be easy! And then you'll learn. It's simple. Remember: read what you want to read. What you like reading. What motivates and inspires you. But where can you start? Well, you could read a book that you've already read in your own language. Simply find a translated version of a book that you have read and enjoyed. This will make processing the content in the target language much easier as you'll already know what the book is about! You could also read the news. This is great as you can read the news in your own language first, then in English. You'll see that it won't be too difficult as you'll be familiar with the topics and stories. Magazines are also great. Find one that covers a topic you're interested in: business, clothing, guns, horses, houses, housekeeping, stocks and shares, sports, computers, electronics, designing, cooking... you name it, they'll have it. If not, look for information on the internet. There are also websites for every topic under the sun! Why not join a...

Question: You can start to read by _ .Options:A reading a book that you've already read in EnglishB reading the news in English firstC going to Google Groups to practice spoken EnglishD reading magazines containing topics you are interested inAnswer:D

[Q]: Write a multi-choice question for the following article: Article: Millions of people visit Yosemite National Park every year to see the tall waterfalls and mountains. These mountains are a splendid sight when viewed from the valley floor. Lots of stores, hotels, and restaurants are needed to handle the crowds. Also, water, roads, and other service systems are part of the infrastructure( )that must be maintained. Unfortunately, these systems are starting to break down. It is not just in Yosemite but in national parks around the nation. Yosemite is thirty years old according to Dennis Galvin, a National Park Service worker. The park is not only old but worn out. Two or three times as many visitors come every year. That is too many visitors for the park to deal with. Four years ago a storm washed out a water pipeline in the Grand Canyon. The National Park Service had to send water trucks to provide water for the visitors. Last month pipe almost broke again and roads had to be closed for a while. Why hasn't the National Park Service kept up the park repairs? There is lack of money. The United States has 378 mountains, parks, and wilderness areas. Between three and four billion dollars are needed for repairs. Yosemite is one national park that does have money fro repairs. It has two hundred million dollars but cannot spend it any way it chooses. When the park workers started widening the road, they were forced to stop by the Sierra Club. The club claimed that the road work was damaging the Merced River that runs through the park. A Sierra Club lawyer, Julia Olson, feels that the infrastructure needs to be moved out of Yosemite. That way less pressure will be put on the already crowed park.
