Ques: Article: How can you find out what is going on inside a person's body without opening the patient's body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs. What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient's body. Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed. A CAT scanner, however, uses a group of X rays to give a cross-sectional view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear "photos" of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can "stop the action", giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient. Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don't cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays. CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives. Question: What is the special use of the latest CAT scanners? Yes or no, is the answer "It provides clear photos of moving organs."?
Ans: Yes

Ques: Article: Where should an adventurous tourist go? After you've done sightseeing in London, shopping in New York tasted the local food in Paris, and danced to your heart's content at the Brazilian carnival, where else can you go? What exotic tourist destination awaits you? Well, Antarctica sounds like the holiday of a lifetime! It's considered the last great wildemess on Earth. Just a few scientists in research stations share the icy landscape with penguins and other animals which can cope with the low temperatures. Tourism began in Antarctica in the 1950s and it's still small scale. About 37,000 tourists are expected there this season, but many won't even leave the boat. The BBC's Juliet Rix visited the frozen continent and asked herself if she should be there at all, causing potential problems to such a sensitive environment. Her tour guide admitted that all visitors leave a footprint and they all go to the same places, the accessible coastline, which is also where the penguins and seals go to breed. But some people believe that if carefully controlled, tourism can be good for Antarctica. It has no native population and it needs advocates. 'Visitors to the icy continent might be ready to support and even to fund its preservation. And they're likely to engage in the discussion about global warming, which has led to the melting of glaciers. According to Rix, guidelines are followed when you're about to set foot in Antarctica and tourists have to disinfect their boots to make sure no alien species are introduced. And once on land, there's no eating or smoking. Rocks, bone fragments - nothing should be taken as a souvenir and nothing should be left behind. Tourists fortunate enough to visit the Antarctica must be aware that this is not their home and keep their fingers crossed that future generations will also be able to enjoy such breathtaking views. Question: Which of the following is the best title of this passage? Yes or no, is the answer "Should tourists go to Antarctica'?"?
Ans: No

Ques: Article: Here is an astonishing and signficant fact:Mental work alone can't make us tired. It sounds absurd. But a few years ago, scientists tried to find out how long the human could labor without reaching a stage of fatigue . To the amazement of these scientists, they discovered thett blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day labourer, we could find it full of fatigue toxins and fatigue products. But if we took blood from the brain of Albert Einstein, it would show no fatigue toxing at the end of the day. So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours f efforts as at the beginning. The brain is totally tireless. So what makes us tired. Some scientists declare that most of our fatigue come from our mental and emotional attitudes. One of England's most outstanding scientists. J. A. Hadfield,says,"The greater part of the fatigue from which we suffer is of mental origin. In fact,fatigue of purely physical origin is rare." Dr. Brill, a famous American scientist, goes even further. He declares,"One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems." What kinds of emotions make sitting workers tired?Joy?Satifaction?No!A feeling of being bored,anger,anxiety,tenseness,worry,a feeling of nt being appreciated---those are emotions that tire sitting workers.Hard work by itself seldom causes fatigue.We get tired because our emotions produce nervousness in the body.
