Article: Spider webs are one of the most fascinating examples of animal architecture. The most beautiful and structurally ordered are the round webs. The main function of the web is to stop and hold flying insects,long enough for the spider to catch them. In order to do so,the threads of the web have to stand the forces from large and heavy insects as well as environmental forces from wind and rain for at least a day in most cases. The round web is found to have two main characteristics. The first is its geometry,which consists of an outer frame and a central part from which threads radiate outward. Enclosed in the frame are capture spirals winding round and round from the web center out to the frame. The whole web is in tension and held in place by anchor threads,which connect the frame to the surrounding plants or objects. The second and perhaps most important characteristic is the material with which it is built. Spider silk is a kind of natural material that gives this lightweight fiber a strength comparable to that of steel, while at the same time making it very elastic . Two types of silk threads are used in the web. One is highly elastic and can stretch to almost twice its original length before breaking and, for most types of spiders, is covered in glue. This type is used in the capture spiral for catching and holding insects. The other is stiffer and stronger,and is used for the radius,frames and anchor threads,which allows the web to stand forces and to keep its structural strength through a wide range of environmental conditions. Question: What is this passage mainly about? Yes or no, is the answer "The structure of round spider webs."?

No

Article: Tuition fees for British students could reach as much as #20,000, a university vicc-president has warned. Prof. Nick Pctfon warned that universities will face additional economic pressures as student numbers increase, which could force them to increase home students' fees. Student tuition is presently upped at #9,000 for British students. Speaking to the lines fligher Education, Prof. Petford, the vice-president of Northampton University,said that some universities with high brand value will be able to charge PS17,000, PS18,000 or PS20,000 in the future. "'I am sure of that. The president of the National Union of Students Toni Pearce said: "The suggestion that tuition fees should be charged at this level shows just how astonishingly out of touch some university vice-presidents can be." Prof. Petford argued there will be a change in how universities view home students - suggesting they will be treated more like international students. "If you look at international students, that's been a market not well-governed since we've been recruiting (tix) overseas students. Universities have always been used to this sort of behaviour." He said. "The big step change now is thinking about home students in this way." Presently there is no cap on fees that universities can charge international students. The president of Universities UK, Christopher Snowden, said that his report showed universities needed more money to maintain their current standards. "The rise in tuition fees in England did not give all universities extra money - it replaced the cuts in direct government funding , " he said. Question: What is Prof. Petford's belief according to the text? Yes or no, is the answer "Good universities can charge students more tuition fees."?

No

Article: My mother fought cancer for almost a decade and died at 56. She held out long enough to meet the first of her grandchildren and to hold him in her arms. But my other children will never have the chance to know her and experience how loving and gracious she was. We often speak of "Mommy's mommy," and I find myself trying to explain the illness that took her away from us. They have asked if the same could happen to me. I have always told them not to worry, but the truth is that I carry a "faulty" gene, BRCA1, which sharply increases my risk of developing breast cancer and ovarian cancer. My doctors estimated that I had an 87 percent risk of breast cancer and a 50 percent risk of ovarian cancer, although the risk is different in the case of each woman. Once I knew that this was my reality, I decided to be proactive and to minimize the risk as much as I could. I started with the breasts, as my risk of breast cancer is higher than my risk of ovarian cancer, and the surgery is more complex. On April 27, I finished the three months of medical procedures. During that time I have been able to keep this private and to carry on with my work. But I am writing about it now because I hope that other women can benefit from my experience. Cancer is still a word that strikes fear into people's hearts, producing a deep sense of powerlessness. But today it is possible to find the way out through a blood test whether you are highly susceptible to breast and ovarian cancer, and then take action. My own process began on February 2. The operation took eight hours. Then I woke up with tubes in my breasts. It did feel like a scene out of a science-fiction film. But days after surgery I can be back to a normal life. There have been many advances in this procedure in the last few years, and the results can be beautiful. I wanted to write this to tell other women that the decision to have a surgery operation was not easy. But it is one I am very happy that I made. My chances of developing breast cancer have dropped from 87 percent to... Question: The writer shares her private story in order to _ . Yes or no, is the answer "help those who might suffer from cancer like her"?
