Will Shortz: Puzzle Maker
When you ask a child what they would like to be when they grow up, common responses might include firefighter, pilot, doctor, or athlete. But those jobs don’t capture the attention of all kids. Take Will Shortz, for example. In eighth grade, at the age of 14, Shortz had to write an essay about what he wanted to do with his life. He wrote about his desire to become a puzzle maker – someone who creates games and puzzles, such as sudoku or crossword puzzles. That same year, he sold his first puzzle to the magazine Venture. By the age of 16, Shortz was regularly contributing puzzles to magazines. In college, Shortz found that there was no traditional way to study puzzles or become a puzzle maker. There were no classes offered on puzzles. Fortunately, after becoming bored with his economics studies, Shortz learned that his university offered a special programme that allowed students to suggest and create unique fields of study. After creating and completing two courses on word and math puzzles, Shortz switched his major to enigmatology – the study of puzzles. Shortz and his professors then created new classes that explored all aspects of puzzle-making. He studied the history, construction, and psychology of puzzles, mostly on his own. Because there were no professors of enigmatology, Shortz realized that he probably was the only student at his university to know more about his field than any of his professors. He did well in school, but upon graduating, Shortz did not know how to get a job creating puzzles. For summer work, he joined the magazine Penny Press, where he realized that he could find work as a puzzle editor. Shortz then found a job creating and editing puzzles for Games magazine. This seemed like a dream job because he could create new kinds of puzzles and be surrounded by great puzzle makers. After 15 years at Games, Shortz accepted a position as the editor of The New York Times’ crossword puzzle. When he first joined, the newspaper’s crossword puzzle was seen as very difficult, and few readers could complete it. Shortz made fundamental changes, such as including everyday language in the clues and answers so that many more people could enjoy it. Today, he credited with making the crossword appealing to a wider audience. Some of Shortz’s most famous puzzles have related to the news for that day, such as the name of the winning president on Election Day, and a love-themed puzzle on Valentine’s Day.

A World without Wires
We are lucky to live in a world that is full of incredible technology. Our living rooms are packed with computers, LCD TVs, video game systems, and Blue-ray players that help us enjoy the latest entertainment. Although these items bring us joy and convenience, they also create a lot of clutter. Each device needs its own plug and adaptor to keep its batteries recharged, and over time these wires get _tangled_. Thankfully, something has come along to help get rid our homes of this mess while still supplying these devices with the power they need. It’s called wireless charging and this trend is just starting. Wireless charging, also known as inductive charging, has a lot of potential for smartphones and other electronic devices. Coils are used to create a magnetic field. Electronic devices can then absorb the electricity once they are placed on a special charging pad. There are several advantages that wireless charging offers over traditional methods. For starters, cords have a tendency to wear out with use. Wireless charging eliminates this hassle so users never have to worry about buying replacement cords. Wireless charging is also far more convenient for medical implants, as patients won’t need to recharge their devices through the skin using cords. In turn, this cuts down on the risks of infection. Wireless charging can also bring safety benefits, as wired charging devices that come in contact with water can increase the chances of getting an electric shock. Wireless charging eliminates that danger completely. Still, there are a few drawbacks to wireless charging. The first is speed. It takes a bit longer to charge devices wirelessly than it does if the device is plugged in. The process also requires more heat, so devices tend to get a bit hotter, which could create other safety issues. Also, since devices must be left on a special pad while charging, it is harder to operate them while they are powering up. This limitation may be eliminated in the future, as researchers are developing transmitters that can charge several different devices in a room without the need to connect to a charging pad. Although wireless-charging technology may be far from perfect, it seems like a step in the right direction as we move towards a less-tangled future.
6. All of the following are the advantages of wireless charging EXCEPT ________

Though called by sweet-sounding names like Firinga or Katrina, tropical cyclones are huge rotating storms 200 to 2,000 kilometers wide with winds that blow at speeds of more than 100 kilometers per hour (kph). Weather professionals know them as tropical cyclones, but they are called hurricanes in the Caribbean Sea, typhoons in the Pacific Ocean, and cyclones in the Indian Ocean. They occur in both the northern and southern hemispheres. Large ones have destroyed cities and killed hundreds of thousands of people.

Tropical cyclones begin over water that is warmer than 27 degrees Celsius (80 degrees Fahrenheit) slightly north or south of the earth’s equator. Warm, humid air full of water vapor moves upward. The earth's rotation causes the growing storm to start to rotate around its center (called the eye). At the certain height, the water vapor condenses, changing to liquid and releasing heat. The heat draws more air and water vapor upward, creating a cycle as air and water vapor rise and liquid water falls. If the cycle speeds up until winds reach 118 kilometers per hour, the storm qualifies as a tropical cyclone.

Most deaths in tropical cyclones are caused by storm surge. This is a rise in sea level, sometimes seven meters or more, caused by the storm pushing against the ocean's surface. Storm surge was to blame for the flooding of New Orleans in 2005. The storm surge of Cyclone Nargis in 2008 in Myanmar pushed seawater nearly four meters deep some 40 kilometers inland, resulting in many deaths.

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:
An air pollutnt is defined as a compound added directly or indirectly by humans to the atmosphere in such quantities as to affect humans, animals, vegetation, or materials adversely. Air pollution requires a very flexible definition that permits continuous change. When the first air pollution laws were established in England in the fourteenth century, air pollutants were limited to compounds that could be seen or smelled – a far cry from the extensive list of harmful subtances known today. As technology has developed and knowledge of the health aspects of various chemicals has increased, the list of air pollutants has lengthened. In the future, even water vapor might be considered an air pollutant under certain conditions.
Many of the more important air pollutants, such as sulfur oxides, carbon monoxide, and notrigen oxides, are found in nature. As the Earth developed, the concentration of these pollutants was altered by various chemical reactions; they became components in biogeochemical cycles. These serve as an air purification scheme by allowing the compounds to move from the air to the water or soil. On a global basis, nature’s output of these compounds dwarfs that resulting from human activities.
However, human production usually occurs in a localized area, such as as city. In such a region, human output may be dominant and may temporarily overload the natural purification scheme of the cycles. The result is an increased concentration of noxious chemicals in the air. The concentrations at which the adverse effects appear will be greater than the concentrations that the pollutants would have in the absence of human activities. The actual concentration need not be large for a subtance to be a pollutant; in fact, the numerial value tells us little until we know how much of an increase this represents over ther concentration that would occur naturally in the area. For example, sulfur dioxide has detectable health effects at 0.08 parts per million (ppm), which is about 400 times its natural level. Carbon monoxide, however, has a natural level of 0.1 ppm and is not usually a pollutant until its level reaches about 15 ppm.

For which of the following reasons can natural pollutants play an important role in controlling air pollution ?

Space Tourism
If you are like most people, you probably dream of spending your next vacation sightseeing or relaxing in a tropical spot. But pretty soon, you may have the option of blasting into space and exploring the universe. It appears that space tourism may start to experience a boom that is sure to be out of this world. Since ancient times, humans have surely dreamed about visiting space. However, it was just a fantasy until 1961, when Soviet cosmonaut Yuri Gagarin became the first person to fly into space. Yet in the years following, only a few highly-trained Soviet and American astronauts managed to leave the Earth’s atmosphere. In the mid-1980s, the US began to relax some of its restrictions. In 1986, an engineer named Charles Walker became the first non-government employee to fly into space. A year later, an American teacher named Christa McAuliffe was chosen to be the first teacher in space. Unfortunately, the Space Shuttle she was on, The Challenger, crashed during takeoff, killing everyone on board. Space tourism got an unexpected boost from the collapse of the Soviet Union. With Russia’s space programme in dire need of money, it became open to offers for space tourism. In 1990, a Japanese reporter was allowed to fly with a Russian crew into space, but the trip would cost his employer $28 million. In the late 1990s, a private company, MirCorp, started organizing trips to space for wealthy individuals. Now, many other companies are trying to do the same. Still, most people who want to become space tourists face a major barrier: the price. Early space tourists have paid dozens of millions of dollars for a seven-to- ten-day stay outside the Earth. However, there are some indications that the price will come down in the near future. Some corporations are gearing up for this with big plans to make space a more hospitable place. The luxurious hotel chain Hilton has expressed interest in opening a space hotel in the next 15 to 20 years. Meanwhile, some experts believe that flights to and from the moon could become a common occurrence within a few decades. Hopefully someday soon we will all have the chance to get to know our solar system a little bit better.
