Read the following article and select the best answer. Article: Early in the 18th century, Captain Cook, a famous explorer of Australia, unexpectedly caught sight of an unusual animal during his first visit to Australia. The animal had a large mouse like head and jumped along on its large legs. To his great surprise, the unusual animal carried its young in a special pocket of flesh. Captain Cook pointed to the animal which was eating grass in the distance and asked his native guide what the animal was referred to. The guide seemed not to know that he was pointing at and finally said "Kang-a-roo", but their requests were met with puzzled looks of the native people. Before long they got to discover that the native guide who made the answer to Cook's question really meant, "I don't know what you pointing at. " Funny enough, the name " Kang-a-roo", stuck and it is still in use today. Question: Which of the following sentences best expresses the main idea? - captain Cook's guide made a joke. - Native Australians could not speak English in Cook's time. - Some words have rather funny origins . - Captain Cook was a lover of wild animals.
Some words have rather funny origins .

(Question)
Read the following article and select the best answer. Article: We all know that it is possible for ordinary people to make their homes on the equator ( ), although often they may feel uncomfortably hot there. Millions do it. But as for the North Pole ---- we know that it is not only a dangerously cold place, but that people like you and we would find it quite impossible to live there. At the present time only the scientists and explorers can do so, and they use special equipment. Men had been traveling across and around the equator on wheels, on their feet or in ships for thousands of years; but only a few men, with great difficulty and in very recent time, have ever crossed the ice to the North Pole. So it may surprise you to learn that, when traveling by air, it is really safer to fly over the North Pole than over the equator. Of course, this is not true about landings in the polar region (which passenger aeroplanes do not make). But the weather, if we are flying at a height of 5,000 meters above the Pole , is a delight. At 4,000 meters and more above the earth you can always be sure that you will not see a cloud in the sky as far as the eye can reach. In the tropics , on the other hand, you are not certain to keep clear of ( ) bad weather even at such heights as 18,000 or 20,000 meters . Aeroplanes can't climb as high or as quickly in cold air as in warm. Nor can clouds. In practice, this is an advantage to the aeroplane, which is already at a good height when it reaches the polar region and so it does not need to climb, while at the same time cold air keeps the clouds down low. Question: Aeroplanes usually do not need to climb quickly or fly high in the polar region because _ . - they can cross the ice with special equipment - there are no clouds above 5000 meters - it is very cold - they do not land there
(Answer)
there are no clouds above 5000 meters

Ques: Read the following article and select the best answer. Article: The biggest danger facing airlines nowadays may not be a terrorist with a gun, but the man with portable computer in business class. In the last 16 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference . The source of this interference remains not proved, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones. RTC.A. an organization which advises the aviation ( )industry, has suggested that all airlines ban such devices from being used during "critical" stages of flight particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently , rules on using these devices are left up to individual airlines. And although some air- lines prevent passengers from using such equipment during take-off and landing, most are unwilling to carry out a total ban, given that many passengers want to work during flight. The difficulty is predicting how electromagnetic fields might affect an aircraft's computers. Experts know that portable devices send out radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not. The fact that aircraft may be fragile to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying,though, is the passenger who can 't hear the instructions to turn off his radio because the music's too loud. Question: The passage is mainly about _ . - a new rule for all airlines - the disadvantages of electronic devices - a possible cause of aircraft incidents - effective safety measures for air flight
Ans: a possible cause of aircraft incidents

Question: Read the following article and select the best answer. Article: My friend Jim and I finally decided to spend our 14 days off in the eastern country.We were arranged to stay with a local family, which made it possible for us to share a real life experience with the locals and in return bring ourselves a richer experience of the native culture and tradition. In the company of one of our well-informed local tour leaders, we started one of the trips to the nearby town . As we were passing elephants, we stopped , confused by the fact that these huge creatures were being held by a small rope tied to their front legs . No chains, no cages. It was obvious that these elephants could, at any time, break away from the ropes they were tied to but for some reason, they did not . My friend went up to the trainer and asked why these beautiful animals just stood there and made no attempt to get away. "Well,"he said , "When they were young and much smaller we used the same size rope to tie them and at that age, it was enough to hold them. As they grow up, they are accustomed to believing that they can not break away. They believe that the rope can hold them, so they never try to break free. We were amazed . These animals could at any time break away from their ropes but just because they believed they couldn't, they were stuck right where they were. Like the elephants, how many of us go through life hanging onto a belief that we can not do something , simply because we failed at it once before ? How many of us are being held by outdated belief that no longer serves us ? How many of us have avoided trying something new because of a limited belief? Worse still , how many of us are being held back by someone else's limiting beliefs? Your attempt may fail but never fail to make an attempt. Question: The elephants never tried to get away because _ . - they believed they couldn't break away from the small ropes - they got used to being raised and controlled by human beings - they had a very close relationship with their trainers - it was hard to break away from the strong and powerful ropes
Answer:
they believed they couldn't break away from the small ropes
