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.

According to the passage, human-generated air pollution in localized regions

Read the passage below carefully, and then choose the best answer:
In 1971, Sue Coppard worked as a secretary in London. While she enjoyed city life, Sue also missed the countryside where she spent most of her time as a child. So she offered to help out on a farm, or more specifically, an organic farming programme organized by a nearby college. She got a few people to volunteer as well, and they spent the weekend doing “housework,” which involved clearing bushes and cleaning drains. Afterwards, the farm managers said they could come back anytime to help out. Sue put a small ad in a magazine, offering people the chance to volunteer at the organic farm. The volunteer programme grew quickly, and soon other organic farmers joined in, asking for people to help out. With so many people and farms involved, someone needed to organize the different groups. A few of the original volunteers started WWOOF (World Wide Opportunities on Organic Farms) to help volunteers and farmers find one another. Today, at least 50 different countries have WWOOF organizations, and many other countries have individual farms that participate in the movement. While WWOOF is still a weekend activity for some, it now welcomes travellers and people who visit to live and work on farms for longer periods of time. WWOOF volunteers can stay on a farm for weeks or even months at a time in exchange for hands-on farming and gardening experience. The work can be exhausting, but volunteers think it’s worth it. By working on farms, the volunteers interact with farmers and develop a love for the outdoors and organic farming. Many travellers now use WWOOFing as a way to visit new countries and experience new cultures. As travellers will discover, every WWOOF opportunity is a bit different. In Serbia, you can find Misa and Olja, a couple whose farm is known for its hard cheeses and for its bread made from homegrown grains. Finca Amiruca, a farm in Ecuador, teaches volunteers how to grow peanuts, plantains, and yucca. When volunteering in Japan, you may get to learn about growing rice. WWOOF is only one of the many unique volunteer opportunities available. Volunteering is something that anyone can do, and a wide variety of organizations accept or even welcome volunteers. So the next time you get the itch to be active on the weekend or on vacation, why not look for a good cause to spend your energy on?

Strengthening Your Core
If there is one indication that someone is fit, it is a tight and lean stomach. Men and women alike hope that eating right and putting in hard work at the gym will earn them a perfect six-patch. Unfortunately, the opposite is also true. The rising popularity of fast food has led to an increase of obesity rates and waistlines around the globe. If someone is out of shape, you will notice the extra weight around their midsection. In both cases, a person’s core muscles seem to tell a lot about their fitness and eating habits. Many people associate the core with just the stomach area, but science actually defines it as our body without arms and legs. Although many people want a solid core to look good, the development of these muscles affects many areas of our lives. In athletics and general life for that matter, we all rely on our core muscles heavily to get things done. Studies have shown that athletes who build a powerful core foundation aren’t injured as much. Meanwhile, the benefits of your average Joe may be even greater. Ordinary people use their core muscles for nearly every task they do. This includes picking things up, sitting in a chair, or tying your shoes. Our core muscles provide stability, so we can keep our balance and easily move in any direction. If we neglect them, life can become much more difficult. As a result, we should always consider our core muscles when designing our workouts. However, if you have been sedentary for years, performing thousands of repetitions will probably get you injured. Instead, start off slowly and gradually build up your numbers. An excellent exercise for both beginners and advanced exercisers is the plank. You simply get in an extended pushup position as if you have just finished a rep. Maintain this position, but place the weight on your forearms instead of your hands. Then, hold the position as long as you can. You should feel your core muscles working hard to help your hands and support the weight of your body. In the beginning, you may only be able to hold it for a few seconds, but keep at it. The Guinness World Record for abdominal planking is three hours and seven minutes.

Billboards that Recognize You
Have you ever felt you were being watched? Some new technologies might make you feel that way. Digital billboards are being created that have the ability to recognize certain characteristics. These high-tech devices have cameras pointed at the people on the street, and software that tries to recognize people by age and gender. A computer inside the billboard then uses this information to display ads that are directed at the people who are looking at the billboard. For example, if a man passes a billboard featuring an ad for cosmetics, the computer can change the ad to something that is more likely to catch the man’s attention, such as a restaurant, or sporting goods. While advertisers see this as a great opportunity to reach their target customers, some people feel that this kind of profiling is an invasion of their privacy. People are now much more aware of how information is exposed, shared, bought, and sold on the Internet. Now this debate will include technologies such as these “smart” billboards. But advertisers claim that they are sensitive to people’s concern about privacy – companies that have tested the billboards in Japan and the US assure consumers that the billboards can only guess your age and gender, but they will not be able to recognize your face or obtain any personal information about you. Until recently, this kind of “personal” advertising has been mostly limited to the Internet. Search engines like Google and Bing can follow what we search for because each computer that connects to those sites has a unique identity. Companies then pay search engines to use this information to display ads for products and services that you have searched for. So if you search for travel information, you are likely to see ads for airlines and hotels. This kind of advertising has proven to be much more effective and valuable than traditional advertising. In addition to taking steps to deliver more personalized messages, advertisers are using billboards to offer more useful information. Digital billboards can connect to the Internet to display information such as the time, weather, and news headlines. In the future, this technology could be used to reflect activity on social media sites or to broadcast ads that relate to local events. In today’s world, people ignore thousands of ads every day. Advertisers are trying to change that trend by personalizing the experience of seeing an ad. So pay attention the next time you see a billboard – it could be talking to you.

An important point to remember if you like spending time out in the open air is that the human head doesn’t work very well outdoors if it becomes too hot, cold or wet.

Read the following passage and choose the best answer (A, B, C, D):
Glenbrook South (GBS) High School is in a suburb of Chicago, lllinois, in the United States. It is an award-winning school with a highly competent teaching staff. It has over 400 Asian Pacific American students-over 17 percent of the students in the school. Of these, the majority are Korean American. This is very unusual in a state where Korean Americans are less than 1 percent of the population. The interactions of the Korean American students at GBS were the subject of an article in Asian Week magazine. Different Korean American students react differently to being in a high school where most students are white. Professor Pyong Gap Min, an expert on Korean life in America, believes that Korean Americans in this situation can sometimes feel inhibited or ashamed of their Korean identity. Asian Week interviewed a number of GBS students, and each had a different attitude. Eighteen-year-old Alice said that she used to spend time only with Korean American friends. Although she felt secure with those friends, she found herself motivated to form closer relationships with non-Koreans, too. She said that she felt she was missing out on new experiences and challenges. Seventeen-year-old John moved in the opposite direction. In junior high school, most of John's friends were white. After coming to GBS, his sense of his Korean American identity was restored, and he decided to have mainly Korean American friends. He feels that he and his Korean American friends understand each other better. For example, they understand about severe parental pressures to succeed at school; John felt his white friends couldn't really understand. Sixteen-year-old Paul has some Korean American friends, but he says he spends most of his time with his white friends. He is often the only Asian American in the group, but he doesn't mind. What Paul likes about the white culture is that he can be more radical - he can be as loud and funny as he wants to be. He says he doesn't see as much of that among the Asian students. Without belittling the importance of what these students had to say, it's important to remember that their opinions at this phase of their lives are bound to change as they grow into adulthood. But these honest opinions can help US better understand issues of cultural relations, and their honesty might help Americans from different cultural groups to get along better in the future.

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 36-42
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.
