Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions:

Who talk more – men or women? Most people believe that women talk more. However, linguist Deborah Tannen, who has studied the communication style of men and women , says that this is a stereotype . According to Tannen, women are more verbal – talk more – in private situations , where they use conversation as the “glue” to hold relationships together. But, she says, men talk more in public situations, where they use conversation to exchange information and gain status. Tannen points out that we can see these differences even in children. Little girls often play with one “best friend”, their play includes a lot of conversation. Little boys often play games in groups; their play usually involves more doing than talking. In school, girls are often better at verbal skills, boys are often better at mathematics.         

A recent study at Emory University helps to shed light on the roots of this difference. Researchers studied conversation between children age 3-6 and their parents. They found evidence that parents talk very differently to their son than they do to their daughters. The startling conclusion was that parents use more language with their girls. Specifically, when parents talk with their daughters , they use more descriptive language and more details. There is also far more talk about emotions, especially sadness, with daughters than with sons.  

Question: Which of the following phrases best explains the meaning of the word "verbal"?

In 776 BC the first Olympic Games were held at the foot of Mount Olympus to honor the Greek’s chief, Zeus. The Greeks emphasized physical fitness and strength in their education of youth. Therefore, contests in running, jumping, discus and javelin throwing, boxing, and horse and chariot racing were held individual cities, and the winners completed every four years at Mount Olympus. Winners were greatly honored by having olive wreaths placed on their heads and having poems sung about their deeds. Originally these were held as games of friendship, and any wars in progress were halted to allow the games to take place. The Greeks attached so much importance to these games that they calculated time in four–year cycle called “Olympiads” dating from 776 BC.  

Question: Where were the first Olympic Games held?

In the primary school, a child is in a comparatively simple setting and most of the time forms and relationships with one familiar teacher. On entering secondary school, a new world opens up and frequently it is a much more difficult world. The pupil soon learns to be less free in the way he speaks to teachers and even to his fellow pupils. He begins to lose radually the free and easy ways of the primary school, for he senses the need for a more cautious approach in the secondary school where there are older pupils. Secondary staff and pupils suffer from the pressures of academic work and seem to have less time to stop and talk. Teachers with specialist roles may see hundreds of children in a week, and a pupil may be able to form relationships with very few of the staff. He has to decide which adults are approachable; good schools will make clear to every young person from the first year what guidance and personal help is available - but whether the reality of life in the institution actually encourages requests for help is another matter. Adults often forget what a confusing picture school can offer to a child. He sees a great deal of movement, a great number of people - often rather frightening-looking people - and realizes that an increasing number of choices and decisions have to be made. As he progresses through the school the confusion may become less but the choices and decisions required will increase. The school will rightly expect the pupil to take the first steps to obtain the help he needs, for this is the pattern of adult of life for which he has to be prepared but all the time the opportunities for personal and group advice must be presented in a way which makes them easy to understand and within easy reach of pupils. 

Question: According to the passage, one of the problems for pupils entering secondary school is that ...........

Quite different from storm surges are the giant sea waves called tsunamis, which derive their name from the Japanese expression for “high water in a harbor”. These waves are also referred to by the general public as tidal waves, although they have relatively little to do with tides. Scientists often referred to them as seismic sea waves, far more appropriate in that they do result from undersea seismic activity. Tsunamis are caused when the sea bottom suddenly moves, during an underwater earthquake or volcano for example, and the water above the moving earth is suddenly displaced. This sudden shift of water sets off a series of waves. These waves can travel great distances at speeds close to 700 kilometers per hour. In the open ocean, tsunamis have little noticeable amplitude, often no more than one or two meters. It is when they hit the shallow waters near the coast that they increase in height, possibly up to 40 meters. Tsunamis often occur in the Pacific because the Pacific is an area of heavy seismic activity. Two areas of the Pacific well accustomed to the threat of tsunamis are Japan and Hawaii. Because the seismic activity that causes tsunamis in Japan often occurs on the ocean bottom quite close to the islands, the tsunamis that hit Japan often come with little warning and can, therefore, prove disastrous. Most of the tsunamis that hit the Hawaiian Islands, however, originate thousands of miles away near the coast of Alaska, so these tsunamis have a much greater distance to travel and the inhabitants of Hawaii generally have time for warning of their imminent arrival. Tsunamis are certainly not limited to Japan and Hawaii. In 1755, Europe experienced a calamitous tsunami, when movement along the fault lines near the Azores caused a massive tsunami to sweep onto the Portuguese coast and flood the heavily populated area around Lisbon. The greatest tsunami on record occurred on the other side of the world in 1883 when the Krakatoa volcano underwent a massive explosion, sending waves more than 30 meters high onto nearby Indonesian islands; the tsunami from this volcano actually traveled around the world and was witnessed as far away as the English Channel.  

Question 13: The passage suggests that the tsunami resulting from the Krakatoa volcano___________.
