Question: Article: Two more cases of H7N9 bird flu virus have been detected in Zhejiang province, including a man who died last week, authorities said on Wednesday. The Chinese Center for Disease Control and Prevention confirmed that a 38-year-old patient surnamed Hong from Hangzhou, the provincial capital, who died in hospital on March 27, had the virus. Hong was infected on March 7 while working in neighboring Jiangsu province. He returned home on March 18, according to the Zhejiang health department. The other patient, surnamed Yang, is a 67-year-old man. He developed a cough and fever on March 25 and was admitted to hospital on Tuesday. None of the people who came into close contact with the patients have developed symptoms of the flu, the health department said. On Sunday, two men in Shanghai died from H7N9. A woman in Anhui province and four men in Jiangsu province remain in _ condition, which makes a large number of people scared to death. All patients had fevers and coughs in the early stages before developing pneumonia and breathing difficulties, China's health authorities said. Experts say genetic analysis shows that the H7N9 virus can be treated with Tamiflu, an antiviral drug that may slow the spread of influenza(,) in the body. Wang Xianjun, head of the Shandong provincial center of disease control, said H7N9 is sensitive to neuraminidase-inhibiting medicine such as Tamiflu, Qilu Evening News reported on Wednesday. There are no effective vaccines for H7N9 as yet, Wang said, but using Tamiflu may be effective in the early stages.

Question: Article: In some parts of the United States, farming is easy. But farming has always been difficult in the northeastern corner of the country, which is called New England. New England has many trees and thin, rocky soil. Anyone who has wanted to start a new farm there has had to work very hard. The first job has been cutting down trees. The next job has been digging the stumps of the trees out of the soil. Then the farmer has had the difficult job of removing stones from his land. This work of removing stones never really ends, because every winter more stones appear. They come up through the thin soil from the rocks below. Farmers have to keep removing stones from the fields. Even today, farms which have been worked on for 200 years keep producing more stones. That is why stone walls are used instead of fences around New England fields. The stone walls are not high; a man can easily climb over them. But they keep the farmer's cows from joining his neighbor's cows.
Answer: why there are many stone walls in New England

Question: Article: MOOCs (Massive Open Online Courses) are free, but without tutoring, and are open to anyone, anywhere in the world. The courses are flexible -- normally three to five hours of study a week -- done at any time, short (5 to 10 weeks) and video-rich. They are also heavily dependent on crowd sourcing: you can discuss a course with fellow students through online forums, discussion boards and peer review. Students don't have to finish the courses, pass assessments or do assignments, but, if they do, they get a certification of participation. The Open University launched FutureLearn, the UK's answer to US platforms such as Coursera, EdX and Udacity, which have been offering MOOCs from top US universities for the past two years. The response has been incredible, with more than three million people registering worldwide. Meanwhile, in 2012, Edinburgh University became the first non-US institution to join Coursera's partnership, comprising 13 universities. "We already run 50 online master's degrees, so this was a logical expansion," says Professor Jeff Haywood, Edinburgh's vice-principal. "It's an investment in teaching methods research. How am I going to teach introductory philosophy to 100,000 people? That's what I call educational R&D." He adds "If you look ahead 10 years, you'd expect all students graduating to have taken some online courses, so you've got to research that. Our MOOCs are no more in competition with our degrees than a lifelong learning course because they don't carry credits." Cooperation is key, Haywood stresses. It is far better to offer 20-30 courses in your own areas of expertise and let other institutions do likewise. Professor Mike Sharples, FutureLearn's academic lead, goes further: "We've tied the elements available before into a package of courses offered by leading universities worldwide on a new software platform, with a new way of promoting it and also a new social-learning teaching method. You won't just receive an exam, but be able to discuss and mark each other's assignments." Bath University, one of more than 20 universities working with FutureLearn, launches its first course, Inside Cancer, next January, and regards MOOCs as a way of breaking down age barriers. "There's no reason why someone doing GCSEs should not look at our MOOCs and get quite a way through them, or someone at PhD level and beyond," says Professor Bernie Morley, expert for learning and teaching.
