SEATTLE (May 1 ) – Researchers at technology firm Nylobe, Inc., are working to develop a sensor capable of detecting corrosion caused by environmental exposure. Corrosion is a major contributor to ---143--- losses in the aircraft industry each year. "This will be a major ---144--- for commercial airline fleets," says Mel Laveau, Nylobe's CEO. "The sensor will decrease both labor and maintenance costs   without being too expensive."
According to Ms. Laveau, the sensor will work by detecting corrosion in its early stages, when the problem can be corrected simply by removing the corroded material. ---145---. In the structure of large aircraft, some critical joints can be particularly susceptible to corrosion. ---146---, the sensor can be used to inspect these areas and then target the most likely areas of concern.

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.

Question‌ ‌29:‌......................

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:
People travel for a lot of reasons: Some tourists go to see battlefields or religious shrines. Others are looking for culture, or simply want to have their pictures taken in front of famous places. But most European tourists are looking for a sunny beach to lie on.

Northern Europeans are willing to pay a lot of money and put up with a lot of inconveniences for the sun because they have so little of it. Residents of cities like London, Copenhagen, and Amsterdam spend a tot of their winter in the dark because the days are so short, and much of the rest of the year in the rain. This is the reason why the Mediterranean has always attracted them. Every summer, more than 25 million people travel to Mediterranean resorts and beaches for their vacation. They all come for the same reason, sun!

The huge crowds mean lots of money for the economies of Mediterranean countries. Italy’s 30,000 hotels are booked solid every summer. And 13 million people camp out on French beaches, parks and roadsides. Spain’s long sandy coastline attracts more people than anywhere else. 37 million tourists visit yearly, or one tourist for every person living in Spain.

But there are signs that the area is getting more tourists than it can handle. The Mediterranean is already one of the most polluted seas on earth. And with increased tourism, it’s getting worse. The French can’t figure out what to do with all the garbage left by campers around St. Tropez. And in many places, swimming is dangerous because of pollution.

None of this, however, is spoiling anyone’s fun. The Mediterranean gets more popular every year with tourists. Obviously, they don’t go there for clean water and solitude. They tolerate traffic jams and seem to like crowded beaches. They don’t even mind the pollution. No matter how dirty the water is, the coastline still looks beautiful. And as long as the sun shines, it’s still better than sitting in the cold rain in Berlin, London, or Oslo.

The word “solid” in paragraph 3 means most nearly the same as     .

Inside a 4D Film
A lot of people think that 3D films are pretty cool. When you watch a 3D film, it sometimes feels like you can reach out and touch the things that you see. In the future, however, 3D might be replaced by something even more advanced: 4D. What you see in a 4D film is the same as what you see in a 3D film. The screen is the same, and the glasses are the same. 4D films are different because they don’t use 3D technology. People in the audience also feel physical things during the films. Let’s look at a few examples. Let’s say that you are watching a film about earthquakes. If you are watching a 4D film, maybe your seat will suddenly start to shake. It will feel like you are in the middle of an earthquake, but you are not. The 4D effects make your seat shake. Or perhaps during the film, one of the characters gives flowers to another character. The people in the cinema might suddenly smell flowers. The point of 4D films is to make people feel like they are in the film. When we watch films these days, we only use two senses: our sense of sight and our sense of hearing. If we use our other senses, the film might feel more real to us. 4D films already exist. The film Avatar was released everywhere in 3D, but in Korea and Hong Kong, it was also released in 4D. People who watched Avatar in 4D feel wind and rain. They also smelled smoke from the weapons in the film, and sometimes their seats moved. Will 4D replace 3D films? It is possible, but we can’t be sure yet. One problem with 4D films is that it is very expensive to show them in theaters. Before a theater shows a 4D film, it has to buy a lot of special equipment. However, 4 films are catching on. Other films shown in 4D include Shrek 4-D, and Iron Man 3.

From smartphones and tablets to apps and social media, society is ambushed from all sides with technology. Naturally, all generations embrace it differently, with younger “digital natives” generally being more connected, more switched-on and more tech literate than older age groups.
According to Pew Research, 92% of Millennials (born 1981–1996) own smartphones, compared with 85% of Gen Xers (born 1965–1980) and 67% of Baby Boomers (born 1946–1964). In terms of tech behavior, older generations tend to use their phones mostly for making calls, whereas for younger generations, a phone is their digital window to the world. Phones are used for social media, going online, texting, emailing, playing games, listening to music, and recording and watching videos.
The daily media consumption of different generations also vastly differs. Gen Z and Millennials favor streaming and online services, with 46% of teens saying they use Netflix compared to 31% of those aged over 16. Furthermore, 16-24s spend 30% of their downtime watching TV or video, compared to 40% of time spent on these activities by the average UK adult. Boomers spend a whopping 344 minutes a day watching regular TV, significantly more than any other age group.
Size also matters more depending on your decade of birth. Younger generations prefer smaller screens sizes, opting for a smartphone as their go-to tech, while Generation X and technology newbies - the Boomers, are going bigger, owning more desktops and tablets. Always in the front of the queue for the hottest tech, younger generations see technology as an integral part of their existence, and since few Millennials and Gen Z can remember a time without social media, they’re more fearless and carefree when it comes to technology. So much so, that a LivePerson report revealed 65% of Millennials and Gen Z interact more with each other online than they do in the real world.
Fundamentally, these behaviors and preferred technologies combine to create a technological generation gap, where employees, shaped by their personal experiences, demonstrate different levels of ability and willingness to adopt new tech. Constantly chasing the next update or device, switched on Millennials and Gen Z are quick to lap up the latest apps, games, and platforms, while Gen X and Boomers are generally slower to embrace technology - both at home and in the workplace.

According to paragraph 2, what is the technological characteristic of Millennials?

Getting Closer to Nature at National Parks
In modern times, we seem to be getting more separate from nature with each passing day. Most of us spend the majority of our time indoors, typing away at computers and fiddling with digital devices. All the while, we are destroying the planet’s natural beauty by cutting down forests and building cities in their place. In an effort to preserve nature for future generations, national parks were created. The primary function of national parks is conservation. In many cases, it is a matter of national pride for countries to protect their indigenous species. Although several nations considered opening national parks, the US was the first country to officially do so when Yellowstone Park opened in 1872. This designation made the federal government responsible for taking care of the territory. Soon after, national parks started to open in Australia, New Zealand, Europe, and eventually across the globe. Today, almost 100 countries have established their own national parks. In total, there are over 6,500 worldwide. There are several incredible national parks that have a lot to offer. Kruger National Park in South Africa at 19,633 square kilometers is one of the largest game reserves. Tourists can go on safari and witness elephants, rhinoceroses, lions, and several other large mammals in their natural environments. At 75,000 square miles, the Northeast Greenland National Park is the world’s largest. In fact, it is larger than all but 30 countries in the world. Despite differences in names, location, and rules, most natural parks have certain traits in common. For one, they are usually open to visitors throughout the year. Those who come to the park can take part in a wide scope of outdoor activities including hiking, camping, cycling, bird watching, and fishing. Other options may include horseback riding, rafting, or scuba diving if the territory is suitable. In most places, visitors are encouraged not to feed the animals. The purpose for this law is twofold: to protect the animals as well as those who might feed them. Animals also have strict dietary needs, so feeding them exotic foods could make them sick. Feeding wild animals could also cause them to aggressively pester humans they encounter in the future for food. However, as long as you follow the rules, you are assured of having a great time at whichever national park you visit.
