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 43 to 50.

Sometimes the road to the future leads through the past. Such was the case for Americans Scott and Brennan Olson, who used an old idea to launch a hot new trend in sports: inline roller skating. 

In 1979, these siblings found a pair of antique roller skates while checking out bargains at a used sporting-goods store. The skates they found had four wheels in a single row instead of the traditional parallel pairs of wheels in front and back. This single row of wheels intrigued the Olsons. They were avid hockey players, and they immediately noticed the similarity between the inline wheels and the long, single blade found on the bottom of ice skates. Could these unusual skates somehow be used to practice hockey off the ice? 

The Olsons set about trying to modify the design of the antique skates that they had found. First they tested out the antique skates to see how well they worked. From those tests, they tried to come up with ways to improve the old design. One improvement involved using special materials to make the skates stronger and easier to steer. The Olsons also added reliable brakes to their inline skates. In 1980, the Olsons founded a company called Rollerblade to make and sell their “new” invention. Sales skyrocketed, and soon millions of people worldwide were “rollerblading,” as inline skating was mistakenly called. 

At first, inline skating was recreational. People enjoyed skating in parks and on streets, and some even danced on skates at giant roller discos. Today, inline “group skates” are popular all over the world. In cities such as San Francisco, Paris, and Berlin, as many as 20,000 skaters might meet on a free day and skate together through the streets. Many people see inline skating as a great way to exercise and socialize. 

By the mid-1990s, inline skating had become more than just a recreational sport. It had developed into several competitive sports. One of the most popular, even today, is aggressive skating. This involves performing tricks and jumping over objects such as boxes, ramps, and rails. Other kinds of competitive skating include speed skating, artistic skating, downhill racing, and skating marathons.  

So, what about hockey? Well, the Olsons achieved their goal. Inline hockey leagues sprang up almost immediately. Then in 1999, inline hockey joined the lineup at the Pan-American Games. There are rumors that inline skating may even become part of the Summer Olympics someday

According to the passage, which of the following is NOT mentioned as a benefit of inline skating?

A. socializing   

B. entertaining         

C. exercising  

D. self-motivating

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

If the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation-conversion of liquid water to water vapor. In this manner, the salinity is increased, since the salt behind. If this is carried to the extreme, of course, white crystals of salt would be left behind.

The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.

Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.

A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.

In the Weddell Sea, off Antarctica, the densest water in the ocean is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world.

Which of the following is NOT a result of the formation of ocean ice? 

A. The surrounding water sinks 

B. Water salinity decreases 

C.The salt remains in the water 

D. The water becomes denser
