Read the following article and select the best answer. Article: World Health Day is celebrated on 7 April to mark the anniversary of the founding of WHO in 1948. Each year a theme is selected for World Health Day that highlights a priority area of public health concern in the world. The theme for 2013 is high blood pressure. High blood pressure increases the risk of heart attacks, strokes . If left uncontrolled, high blood pressure can also cause blindness, irregularities of the heartbeat and heart failure. The risk of developing these complications is higher in the presence of other risk factors such as diabetes . One in three adults worldwide has high blood pressure and this increases with age, from 1 in 10 people in their 20s and 30s to 5 in 10 people in their 50s. High blood pressure is most common in some low-income countries in Africa, with over 40% of adults in many African countries thought to be affected. However, high blood pressure is both preventable and treatable. In some developed countries, prevention and treatment of it has brought about a reduction in deaths from heart disease. The risk of developing high blood pressure can be reduced by: reducing salt intake; eating a balanced diet; avoiding harmful use of alcohol; taking regular physical activity; keeping a healthy body weight; and avoiding tobacco use. The final and most important goal of World Health Day 2013 is to reduce heart attacks and strokes, which includes as follows: 1.to raise awareness of the causes and consequences of high blood pressure; 2.to provide information on how to prevent high blood pressure 3.to encourage adults to check their blood pressure and to follow the advice of health-care professionals. Question: Which of the following can NOT reduce the risk of developing high blood pressure? - Less salt intake - Putting on weight - Regular exercise - No smoking
Putting on weight

Read the following article and select the best answer. Article: Students and Technology in the Classroom I love my blackberry -- it's my little connection to the larger world that can go anywhere with me. I also love my laptop computer,as it holds all of my writing and thoughts. Despite this love of technology, I know that there are times when I need to move away from these devices and truly communicate with others. On occasion, I teach a course called History Matters for a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas. Because I want students to thoroughly study the material and exchange their ideas with each other in the classroom, I have a rule -- no laptop, iPads, phones ,etc .When students were told my rule in advance of the class, some of them were not happy. Most students assume that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There's a bit of truth to that. Some students assume that I am anti-technology. There's no truth in that at all. I love technology and try to keep up with it so I can relate to my students. The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly _ complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas. I want students to dig deep within themselves for inspiration and ideas. I want them to push each other to think differently and make connections between the course the material and the class discussion. I've been teaching my history class in this way for many years and the evaluations reflect student satisfaction with the environment that I create. Students realize that with deep conversation and challenge, they learn at a level that helps them keep the course material beyond the classroom. I'm not saying that I won't ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I'm... Question: According to the author, the use of technology in the classroom may _ . - keep students from doing independent thinking - encourage students to have in-depth conversations - help students to better understand complex themes - affect students' concentration on course evaluation
(Answer)
keep students from doing independent thinking

Ques: Read the following article and select the best answer. Article: In the countries of South and Southeast Asia, the elephant has been an important part of the culture, economy and religion for centuries. And nowhere more so than in Thailand. Unlike its African cousin, the Asian elephant is easily domesticated . The rare so-called white elephants have actually lent the power of royalty to its rulers,and until the 1920s the national flag was a white elephant on a red background. To the early Western visitors, the country's romantic name was" Land of the White Elephant". Today, however, the story is very different. Out of work and out of land, the Thai elephant struggles for survival in a nation that no longer needs it. The elephant has found itself more or less deserted by previous owners who have moved on to a different economic world and a society in the western part. And while the elephant's problems began many years ago, now it has a very low national advantage. How does the national symbol turn into ignored animals? It is a story of worse environment and the changing lives of the Thais themselves. According to Richard Lair, Thailand's expert on the Asian elephant and author of the report Gone Astray, at the turn of the last century, there may well have been as many as 100,000 national elephants in the country. In the north of Thailand alone, it was estimated that more than 20,000 elephants were employed in transport, 1,000 of them alone on the road between the cities of Chiang Mai and Chiang Saen. This was at a time when 90 percent of Thailand was still forest---a habitat that not only supported the animals but also made them necessary to carry goods and people. Nothing ploughs through thick forest better than lots of sure-footed elephants. By 1950 the elephant population had dropped, but still to the number of 13, 397. However, today there are probably no more than 3,800, with another l,350 wandering free in the national parks. But now, Thailand's forest covers only 20 percent of the land. This deforestation is the central point of the elephant's difficult situation,... Question: What can we know about African elephants from the passage? - It is of little value to domesticate them. - It is hard to domesticate them. - They are living a better life than Asian elephants. - Their fate is quite similar to that of Asian elephants.
Ans: It is hard to domesticate them.

Ques:Read the following article and select the best answer. Article: British and American scientists are raising genetically modified pigs in the hope of providing organs for transplant to humans, the project leader wrote in a newspaper Sunday. Scientists in London and California have begun conducting the genetic experiments to find a solution to record-long waiting lists for organ transplants, Robert Winston said in an opinion piece written for Britain's Sunday Times. In Britain alone, around 8,000 patients are waiting for a transplant. "People needing a new heart or liver are waiting for someone else to die -usually a violent death in a traffic accident," Winston wrote in the newspaper. He said his team was "trying to modify pigs so their organs might save the lives of humans." The scientists are introducing human genes into the animals to reduce the chances of the organs being rejected by patients, as has been common in previous attempts to use animal tissues, said Winston, who heads the Institute of Reproductive and Developmental Biology at London's Hammersmith Hospital. Working with Dr. Carol Redhead of the California Institute of Technology, Winston's team has injected human genes directly into male piglets , adding them to the animal's sperm . He said that pigs involved in experiments had successfully produced transgenic sperm, but acknowledged that British and European laws had prevented the team from using the pigs to mate. The Sunday Times newspaper reported that the experiments would be moved to the United States following difficulties with funding and regulations in Britain. It said the pigs would be bred in Missouri. "Our U.S. friends will benefit from our technology and the income we might have produced for Britain will be lost," Winston wrote. Some scientists have previously blamed the idea of using animal organs for human transplant, saying the technique risks spreading animal viruses to humans. Winston said his research project is attempting to breed virus-free pigs. Question: According to Winston, it seems _ to Britain to move the experiments to the United States. - a pity - a pride - a disaster - a good idea

Ans:
a pity
