The airplane was built using only a computer--but it can fly at a speed of 100mph and has a two-meter wingspan. It was produced using a special nylon laser printer that builds up something layer-by-layer. The parts were made separately and attached using a "snap fit" technique so the aircraft could be put together without tools in minutes. No fasteners at all were used in the manufacture of the plane. Unmanned and electrically powered, the plane can travel in near silence and is also equipped with a small autopilot system. The special production process used is known as "laser sintering "and allows the designers to create shapes and structures that would normally include costly manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from your own design to first flight in days, while using traditional materials and techniques would take months. And because no tooling is required for manufacture, major changes to the shape and scale of the aircraft can be made with no extra cost. Professor Jim Scanlon, who led the team, said, "The process allows the design team to revisit historical techniques and ideas that would have been too expensive using traditional manufacturing." He added, "This form of structure is very firm and lightweight, but very complex. If it was manufactured traditionally it would require a large number of individually tailored parts that would have to be connected or fastened at great expense." The new printed plane is known as the Southampton University Laser Sintered Aircraft--or SULSA for short--and is part of a wider project using cutting-edge manufacturing techniques. The University of Southampton has been at the leading position of Unmanned Aerial Vehicle development since the early 1990s. Question: This kind of plane has the following advantages EXCEPT _ . Options: A: it produces little noise while flying B: it is manufactured in quite a short time C: it only requires simple and cheap tools D: it needn't extra cost if changes are made

Read the article and select the best answer. Article: We've reached a strange--some would say unusual--point. While fighting world hunger continues to be the matter of vital importance according to a recent report from the World Health Organization (WHO), more people now die from being overweight, or say, from being extremely fat, than from being underweight. It's the good life that's more likely to kill us these days. Worse, nearly l8 million children under the age of five around the world are estimated to be overweight. What's going on? We really don't have many excuses for our weight problems. The dangers of the problem have been drilled into us by public-health campaigns since 2001 and the message is getting through--up to a point. In the 1970s, Finland, for example, had the highest rate of heart disease in the world and being overweight was its main cause. Not any more. A public-health campaign has greatly reduced the number of heart disease deaths by 80 per cent over the past three decades. Maybe that explains why the percentage of people in Finland taking diet pills doubled between 2001 and 2005, and doctors even offer surgery of removing fat inside and change the shape of the body. That has become a sort of fashion. No wonder it ranks as the world's most body-conscious country. We know what we should be doing to lose weight--but actually doing it is another matter. By far the most popular excuse is not taking enough exercise. More than half of us admit we lack willpower. Others blame good food. They say: it's just too inviting and it makes them overeat. Still others lay the blame on the Americans, complaining that pounds have piled on thanks to eating too much American-style fast food. Some also blame their parents--their genes. But unfortunately, the parents are wronged because they're normal in shape, or rather slim. It's a similar story around the world, although people are relatively unlikely to have tried to lose weight. Parents are eager to see their kids shape up. Do as I say--not as I do. Question: The example of Finland is used to illustrate _ . Options: A: the cause of heart disease B: the fashion of body shaping C: the effectiveness of a campaign D: the history of a body-conscious country
(Answer)
C
