Read the following article and select the best answer. Article: Science has a lot of uses. It can uncover laws of nature, cure diseases, make bombs, and help bridges to stand up. Indeed science is so good at what it does that there's always a temptation to drag it into problems where it may not be helpful. David Brooks, author of The Social Animal: The Hidden Sources of Love, Character, and Achievement, appears to be the latest in a long line of writers who have failed to go against the temptation. Brooks gained fame for several books. His latest book The Social Animal, however, is more ambitious and serious than his earlier books. It is an attempt to deal with a set of weighty topics. The book focuses on big questions: What has science uncovered about human nature? What are the sources of character? And why are some people happy and successful while others aren't? To answer these questions, Brooks studies a wide range of disciplines . Considering this, you might expect the book to be a simple description of facts. But Brooks has formed his book in an unusual, and perhaps unfortunate way. Instead of introducing scientific theories, he tells a story, within which he tries to make his points, perhaps in order to keep the reader's attention. So as Harold and Erica, the hero and heroine in his story, live through childhood, we hear about the science of child development and as they begin to date we hear about the theory of sexual attraction. Brooks carries this through to the death of one of his characters. On the whole, Brooks' story is acceptable if uninspired. As one would expect, his writing is mostly clear and, to be fair, some chapters stand out above the rest. I enjoyed, for instance, the chapter in which Harold discovers how to think on his own. While Harold and Erica are certainly not strong or memorable characters, the more serious problems with The Social Animal lie elsewhere. These problems partly involve Brooks' attempt to translate his tale into science. Question: What is the author's general attitude towards the book? - Contradictory. - Supportive. - Cautious. - Critical.
Critical.

Read the following article and select the best answer. Article: As if there weren't enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects , which are very easy to experiment with , will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic stem cells. In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly 'reprogrammed'. Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos might be grown in selected solutions that change the activity of those genes to improve the technique's success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei (pl)out of developing fly embryos, and injected them into a fertilized fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics. Question: The scientists cloned flies because _ . - there are fewer and fewer flies in the world - flies are easy to find and cheap to use - they can gain some experience before cloning other animals - it is safe to clone flies
(Answer)
they can gain some experience before cloning other animals

Ques: Read the following article and select the best answer. Article: I believe that it is important to be brought up with a firm belief in the good. I was fortunate in this respect. My parents not only gave me a happy home, but they had me study half a dozen foreign languages and made it possible for me to travel in other countries. This made me more tolerant and helped me to bridge many difficulties in later life. Soon after I got married, my husband and I left our native Czechoslovakia and went to live in Shanghai, China. Here was a really international city. People of all races and beliefs lived and worked together. In Shanghai, in 1941, when I was only twenty years old, the doctors discovered that I had diabetes. It was a terrible shock, because diabetes is incurable. But it can be controlled by insulin . Although this drug was not manufactured in China, there were enough stocks of imported insulin available. This enabled me to continue a normal, happy life. Then bombs fell on Pearl Harbor and the Japanese occupied Shanghai. The import of insulin was cut off. Before long, there was not enough for the diabetics. I was on a starvation diet to keep my insulin requirements as low as possible. Many diabetics had already died, and the situation became desperate. In spite of all this, I never stopped believing that with the help of my husband's love and care, I would survive. I continued to teach in Chinese schools. My faith and my husband's never-ending efforts to get the manufacture of insulin started gave me courage. In his small laboratory the production of insulin was attempted. I served as the human guinea pig on which was tested. I'll never forget the day when my husband gave me the first injection of the new insulin, which had worked on rabbits. It helped! Can you imagine our happiness and relief? I received the greatest strength from the deep love and complete understanding between my husband and me. And next to that was the kindness and help of many, many friends of many nationalities. To me, the experience of living in Shanghai during the special times was... Question: How does the author feel about her stay in China? - Unbearable. - Unbelievable. - Unfortunate. - Unforgettable.
Ans: Unforgettable.

Ques: Read the following article and select the best answer. Article: Travel is exciting and summer is a busy period for holiday travel. Many people will travel great distances in airplanes, cars or other vehicles. Experts say people should know about other health problems that can strike when traveling by air. One of these is a condition called hypoxia . It results from a lack of oxygen to the brain. Experts say the body begins losing oxygen minutes after an airplane leaves the ground. The air pressure in a plane during flight is lower than at sea level. This makes it more difficult for the body to effectively use the same amount of oxygen as it would on the ground. Fewer oxygen molecules cross the tissues in the lungs and reach the bloodstream. The result is a five to twenty percent drop in the amount of oxygen in the blood. This reduces the amount of oxygen that reaches the organs of the body. One effect of this lack of oxygen to the brain is a headache. When this happens, the heart attempts to _ by beating harder and faster. This can make the traveler feel tired. These signs of hypoxia are not dangerous in a healthy person. But a drop in oxygen level can cause a health emergency in people with heart or lung problems. They might lose consciousness or even suffer a heart attack. Experts say that smoking cigarettes and drinking alcoholic liquids also reduce the body's ability to use oxygen. So they suggest that people not drink alcohol or smoke cigarettes either before or during a flight. They also say persons with heart or lung problems should seek advice from their doctors before flying. Question: Do you think which the following title is the best title for this passage? - Tralling - how to travel - some suggestions about on the plane while travelling - the causes and effects of hypoxia
Ans:
the causes and effects of hypoxia
