   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.

What is NOT true about the Beatles?

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.

In water polo, the players score a goal by _______.

   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.

Most of the public assistance programs ______ after the severe economic crisis.

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."

Which of the following is NOT true, according to the passage?

   Millions of people are using cellphones today. In many places, it is actually considered unusual not to use one. In many countries, cellphones are very popular with young people. They find that the phones are more than a means of communication – having a mobile phone shows that they are cool and connected.

   The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

   On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn’t remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer’s doctor didn’t agree.

   What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

   As the discussion about their safety continues, it appears that it’s best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it’s wise not to use your mobile phone too often.

The changes possibly caused by the cellphones are mainly concerned with ______.

For more than six million American children, coming home after school means coming  back to an empty house. Some deal with the situation by watching TV. Some may hide. But all of  them have something in common. They spend part of each day alone. They are called “latchkey children”. They are children who look after themselves while their parents work. And their bad  condition has become a subject of concern. 
Lynette Long was once the principal of an elementary school. She said, “We had a school rule against wearing jewelry. A lot of kids had chains around their necks with keys attached. I was  constantly telling them to put the keys inside shirts. There were so many keys; it never came to  my mind what they meant.” Slowly, she learned that they were house keys. She and her husband began talking to the children who had keys. They learned of the effect working couples and single parents were having on their children. Fear was the biggest problem faced by children at home alone. One in three latchkey children the Longs talked to reported being  frightened. Many had nightmares and were worried about their own safety. The most common way latchkey children deal with their fears is by hiding. They may hide  in a shower stall, under a bed or in a closet. The second is TV. They often turn the volume up. It’s  hard to get statistics on latchkey children, the Longs have learned. Most parents are slow to admit  that they leave their children alone

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).

Which of the following is not required in Synchronized Swimming?
