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 questions from 31 to 35.
Marcel Bich, a French manufacturer of traditional ink pens, was the man turning the ballpoint pen into an item that today almost anyone can afford. Bich was shocked at the poor quality of the ballpoint pens that were available, and also at their high cost. However, he recognised that the ballpoint was a firmly established invention, and he decided to design a cheap pen that worked well and would be commercially successful.
Bich went to the Biro brothers and asked them if he could use the design of their original invention in one of his own pens. In return, he offered to pay them every time he sold a pen. Then, for two years, Bich studied the detailed construction of every ballpoint pen that was being sold, often working with a microscope.
By 1950, he was ready to introduce his new wonder: a plastic pen with a clear barrel that wrote smoothly, did not leak and only cost a few cents. He called it the 'Bic Cristal'. The ballpoint pen had finally become a practical writing instrument. The public liked it immediately, and today it is as common as the pencil. In Britain, they are still called Biros, and many Bic models also say 'Biro' on the side of the pen, to remind people of their original inventors.
Bich became extremely wealthy thanks to his invention, which had worldwide appeal. Over the next 60 years his company, Société Bic, opened factories all over the world and expanded its range of inexpensive products. Today, Bic is as famous for its lighters and razors as it is for its pens, and you can even buy a Bic mobile phone.

According to the passage, which of the following is NOT mentioned as products of Bich's company?

   In the 1960s, The Beatles were probably the most famous pop group in the whole world. Since then, there have been a great many groups that have achieved enormous fame, so it is perhaps difficult now to imagine how sensational The Beatles were at that time. They were four boys from the north of England and none of them had any training in music. They started by performing and recording songs by black Americans and they had some success with these songs. Then they started writing their own songs and that was when they became really popular. The Beatles changed pop music. They were the first pop group to achieve great success from songs they had written themselves. After that it became common for groups and singers to write their own songs. The Beatles did not have a long career. Their first hit record was in 1963 and they split up in 1970. They stopped doing live performances in 1966 because it had become too dangerous for them - their fans were so excited that they surrounded them and tried to take their clothes as souvenirs! However, today some of their songs remain as famous as they were when they first came out. Throughout the world, many people can sing part of a Beatles song if you ask them.

The Beatles stopped their live performances because __________

   Traditionally in America, helping the poor was a matter for private charities or local governments. Arriving immigrants depended mainly on predecessors from their homeland to help them start a new life. In the late 19th and early 20th centuries, several European nations instituted public-welfare programs. But such a movement was slow to take hold in the United States because the rapid pace of industrialization and the ready availability of farmland seemed to confirm the belief that anyone who was willing to work could find a job.

   Most of the programs started during the Depression era were temporary relief measures, but one of the programs Social Security – has become an American institution. Paid for by deductions from the paychecks of working people, Social Security ensures that retired persons receive a modest monthly income and also provides unemployment insurance, disability insurance, and other assistance to those who need it. Social Security payments to retired persons can start at age 62, but many wait until age 65, when the payments are slightly higher. Recently, there has been concern that the Social Security fund may not have enough money to fulfill its obligations in the 21st century, when the population of elderly Americans is expected to increase dramatically. Policy makers have proposed various ways to make up the anticipated deficit, but a long-term solution is still being debated. In the years since Roosevelt, other American presidents have established assistance programs. These include Medicaid and Medicare; food stamps, certificates that people can use to purchase food; and public housing which is built at federal expense and made available to persons on low incomes. Needy Americans can also turn to sources other than the government for help. A broad spectrum of private charities and voluntary organizations is available. Volunteerism is on the rise in the United States, especially among retired persons. It is estimated that almost 50 percent of Americans over age 18 do volunteer work, and nearly 75 percent of U.S. households contribute money to charity.

The Social Security program has become possible thanks to ______.

Walt Disney was born in 1901 in Chicago, but soon moved to a small farm near Marceline, Missouri. From this rural and rather humble beginning he later became one of the most famous and beloved motion-picture producers in history. Although he died in 1966, his name and artistic legacy continue to influence the lives of millions of people throughout the world.
After several years of barely making ends meet as a cartoon artist operating from his Los Angeles garage, Disney had his first success in 1928, with his release of a Mickey Mouse cartoon. Throughout the next decade, he continued to produce a number of cartoons, and develop more of his highly profitable and enduring creations, such as Donald Duck and Pluto. In the late 1930s, he issued full-length cartoon film. Snow White became an instant commercial and critical success. This was only the first of many films, both animated and not, produced by Disney and his studio.
But as renowned as Disney name is for cartoon and monies, it is probably best known for a string of spectacular amusement and theme parks. Starting with California's Disneyland in 1955 and culminating with the fantastically successful Disney World and EPCOT Center in Florida, Disney became a household name. In recent years, the theme park concept became international, with openings in Toyo and Paris. With the continuing success of Disney, the creation of future theme park are under discussion.

The word "enduring" in bold in paragraph 2 is closest in meaning to _______.

Synchronized swimming is a hybrid of swimming, gymnastics, and dance, consisting of swimmers (either individuals, duets, trios, teams or combos) performing a synchronized routine of elaborate and dramatic moves in the water, accompanied by music. 
Synchronized swimming demands proficient water skills, and requires strength, endurance, flexibility, grace, artistry and precise timing, not to mention exceptional breath control while upside down underwater. Developed in the early 1900 s in Canada, it is a sport performed almost exclusively by women, although there is some participation by men. In its early form it was some-times known as 'water ballet". 
It is a Summer Olympic Games sport. First demonstrated in 1952, it has been an official event since 1984. Olympic and World Championship competition is not currently open to men; but other international and national competitions allow male competitors: Both USA Synchro and Synchro Canada allow men to compete with women. 
Competitors show off their strength, flexibility, and aerobic endurance required to perform difficult routines. Swimmers perform two routines for the judges, one technical and one free.
Synchronized Swimming is governed internationally by FINA (Federation Internationale de Natation Amateur).

In the Synchronized Swimming competition, competitors ________

Scientists have discovered the bones of what may be the largest meat-eating dinosaur ever to walk the earth. The discovery was made by a team of researchers from Argentina and North America in Patagonia, a desert on the eastern slopes of the Andes in South America. Besides the interesting fact that the dinosaur was huge and horrifying, it is even more astounding that the bones of a number of the dinosaurs were found together. This discovery challenges the prior theory that the biggest meat-eaters lived as loners and instead indicates that they may have lived and hunted in packs. The Tyrannosaurus Rex lived in North America and was believed to hunt and live alone.
The newly discovered meat-eater appears to be related to the Giganotosaurus family, being as closely related to it as a fox would be to a dog. It is actually not of the same family at all as the Tyrannosaurus Rex, being as different from it as a cat is from a dog.
The fossilized remains indicate that the animals lived about 100 million years ago. With needle-shaped noses and razor sharp teeth, they were larger than the Tyrannosaurus Rex, although their legs were slightly shorter, and their jaws were designed to be better able to dissect their prey quickly and precisely.

The word it in the second paragraph refers to ________.

Read the passage below and choose one correct answer for each question.

There is very little documentation about the origins of water polo. It is known, however, that the sport originated in the rivers and lakes of mid-19th century England as an aquatic version of rugby. Early games used an inflated rubber ball that came from India known as a "pulu" (the single Indian word for all "balls"). Pronounced "polo" by the English, both the game and the ball became known as "water polo". To attract more spectators to swimming exhibitions, the London Swimming Association designed a set of water polo rules for indoor swimming pools in 1870. At first, players scored by planting the ball on the end of the pool with both hands. A favorite trick of the players was to place the five-to-nine inch rubber ball inside their swimming suit and dive under the murky water, they would then appear again as close to the goal as possible. The introduction of the rules by Scottish players changed the nature of water polo. It became a game that emphasized swimming, speed and passing. Scottish rules moved from a rugby variant to a soccer style of play. Goals became a cage of 10x 3 feet and a goal could be scored by being thrown. Players could only be tackled when they "held" the ball and the ball could no longer be taken under water. The small rubber ball was replaced by a leather soccer ball. If the player came up too near the goal, he was promptly jumped on by the goalie, who was permitted to stand on the pool deck. Games were often nothing more than gang fights in the water as players ignored the ball, preferring underwater wrestling matches that usually ended with one man floating to the surface unconscious. Water polo was first played in the USA in 1888. The game featured the old rugby style of play which resembled American football in the water. "American style" water polo became very popular and by the late 1890s was played in such venues as Madison Square Garden and Boston's Mechanics Hall, attracting 14,000 spectators to national championship games.

Read the passage carefully, then choose the correct answer: 
Underwater hockey is a non-contact sport in which two teams compete to maneuver a puck across the bottom of a swimming pool into goals. 
Players wear a diving mask, fins, speedos and a snorkel for play_ Safety gear includes a water polo style cap, a mouthguard, and a glove for the playing hand (to protect against pool-bottom abrasion and, in some designs, knuckle protection against puck impact). Because current rules permit a player to switch the stick between hands mid-play, players may choose to wear a protective glove on both hands. The stick is quite short (not more than 350 mm in length, including the handle) and is colored white or black to indicate the player's team.
Two teams of up to ten players compete, with six players on each team in play at once. Substitution happens continually from a substitution area, which may be on deck or in the water outside the playing area, depending on tourna went rules. Before the start of play the puck is placed in the middle of the pool, and the players wait in the water, touching the wall above the goals they are defending. At the start-of-play signal, in- play members of both teams are free to swim anywhere in the play area and try to score by sending the puck into the opponents' goal. Play continues until either a goal is scored, and players return to their wall to start a new point, or a break in play is signaled by a referee. 
There are a number of penalties described in the official underwater hockey rules, ranging from use of the stick against something (or someone) other than the puck or the playing surface, playing or stopping the puck with something other than the stick, and "screening". If the penalty is minor, referees award an advantage puck - the team that committed the foul is pushed back 3 meters from the puck, while the other team gets a free possession. For major penalties, such as a dangerous pass or intentional or repeated fouls, the referees may eject. players for a specified period of time or the remainder of the game. A defender committing a serious foul sufficiently close to his own goal may be penalized by the award of a point to the fouled player's team.
Games consist of two halves, typically ten to fifteen minutes in length (depending on tournament rules; 15 minutes at world championship tournaments) and a short half time interval. At half time the two teams switch ends.

How long does a game of underwater hockey last?

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 questions from 36 to 42.
A study was set up to examine the old marriage advice about whether it's more important to be happy or to be right. Couples therapists sometimes suggest that in an attempt to avoid constant arguments, spouses weigh up whether pressing the point is worth the misery of marital discord. The researchers from the University of Auckland noticed that many of their patients were adding stress to their lives by insisting on being right, even when it worked against their well-being.
The researchers then found a couple who were willing to record their quality of life on a scale of 1 to 10. They told the man, who wanted to be happy more than right, about the purpose of the study and asked him to agree with every opinion and request his wife had without complaint, even when he profoundly didn't agree. The wife was not informed of the purpose of the study and just asked to record her quality of life.
Things went rapidly downhill for the couple. The man's quality-of-life scores fell, from 7 to 3, over the course of the experiment. The wife's scores rose modestly, from 8 to 8.5, before she became hostile to the idea of recording the scores. Rather than creating harmony, the husband's agreeableness led to the wife becoming increasingly critical of what he did and said (in the husband's opinion). After 12 days he broke down, and the study was called off because of severe adverse outcomes."
The researchers concluded, shockingly, that humans need to be right and acknowledged as right, at least some of the time, to be happy. They also noted this was further proof that if given too much power, humans tend to "assume the alpha position and, as with chimpanzees, they become very aggressive and dangerous." It is often said that there can be no peace without justice, and that's true of domestic sphere.
Obviously the results are to be taken with extreme caution, since this was just one couple with who-knows-what underlying issues beforehand. But the study's chief author, Dr. Bruce Arroll, maintains that the question of happiness vs. rightness, theoretically, could be settled by scientific inquiry with a wider sample. "This would include a randomized controlled trial,” he says. "However, we would be reluctant to do the definitive study because of the concern about divorce."

In paragraph 1, the study was conducted in order to ________.
