Read the passage and choose the best answer:

Synchronized swimming is a hybrid form of swimming, dance and figure skating which consists 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 advanced 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 1900s in Canada, it is a sport performed almost exclusively by women, although there is some participation by men. In its early form it was sometimes 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. In competition, 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.

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 author states that the newly discovered meat-eating dinosaur is ________.

Câu 13:

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.

In future years it is most likely that _______.

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?

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.

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.

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
