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:
The economic expansion prompted by the Second World War triggered a spectacular population boom in the West. Of course, the region was no stranger to population booms. Throughout much of its history, western settlement had been characterized by spurts, rather than by a pattern of gradual and steady population growth, beginning with the gold and silver rushes of the 1850's and 1860's. The decade after the First World War - the 1920's - witnessed another major surge of people pouring into the West, particularly into urban areas. But the economic depression of the 1930's brought this expansion to a halt; some of the more sparsely settled parts of the region actually lost population as migrants sought work in more heavily industrialized areas. By 1941 when the United States entered the Second World War and began to mobilize, new job opportunities were created in the western part of the nation.

If the expansion of industries, such as shipbuilding and aircraft manufacturing, was most striking on the pacific coast, it also affected interior cities like Denver, Phoenix, and Salt Lake City. Equally dramatic were the effects of the establishment of aluminum plants in Oregon and Washington and the burgeoning steel industry in Utah and California. The flow of people into these areas provided an enormous impetus to the expansion of the service industries - banks, health care services and schools. Although strained to the limit by the influx of newcomers, western communities welcomed the vast reservoir of new job opportunities. At the same time, the unprecedented expansion of government installations in the West, such as military bases, created thousands of new civilian openings. As land had served as a magnet for western migrants in the late nineteenth century, so wartime mobilization set in motion another major expansion of population. Indeed, it could be said that the entire western United States became a giant boomtown during the Second World War. This was especially true of California. Of the more than eight million people who moved into the West in the decade after 1940, almost one-half went to the Pacific coast. In fact, between 1940 and 1950, California's population surged by more than three million people.

Telecommunicating is a form of computer communication between employees’ homes and offices. For employees whose jobs involve sitting at a terminal or word processor entering data or typing reports, the location of the computer is of no consequence. If the machine can communicate over

telephone lines, when the work is completed, employees can dial the office computer from a distant site and transmit the material to their employers. A recent survey in USA Today estimates that there are approximately 8.7 million telecommuters. But although the numbers are rising annually, the trend does not appear to be as significant as predicted when Business Week published "The Portable Executive" as its cover story a few years ago. Why hasn't telecommuting become more popular?
Clearly, change simply takes time. But in addition, there has been active resistance on the part of many managers. These executives claim that supervising the telecommuters in a large work force scattered across the country would be too difficult, or, at least, systems for managing them are not yet developed, thereby complicating the manager's responsibilities.
It is also true that employees who are given the option of telecommuting are often reluctant to accept the opportunity. Most people feel that they need regular interaction with a group, and many are concerned that they will not have the same consideration for advancement if they are not more visible in the office setting. Some people feel that even when a space in their homes is set aside as a work area, they never really get away from the office.

Microwave Magic
The 20th century was a time in which many great inventions were created. Things like the automobile, computers, and the Internet truly changed the way we live forever. Yet, one handy invention that has made eating at home far more convenient is often overlooked. The invention of microwave allowed even the worst cooks in the world to prepare a meal in essentially no time at all. What is really fascinating about microwave ovens is that they were invented by accident. During World War II, British scientists discovered a device called a magnetron that can produce microwaves. They hoped it would help them quickly identify German planes that were intent on bombing their nation. However, it would be an American scientist named Percy Spencer who linked microwaves with cooking food. One day, Spencer brought a candy bar with him to work, and he stored it in his shirt pocket. While walking through a radar set, he noticed that the radar had somehow melted his treat. Afterwards, Spencer and his coworkers started to experiment with heating other things. They tried heating some popcorn kernels and it worked like a charm. Next, they tried to cook an egg with microwaves, but it literally blew up in their face. In 1945, the company that Spencer worked for, Raytheon, filed a patent for the technology and started working on ways to make microwave ovens more efficient. The first commercial microwave ovens hit the market, and an industry was born. In the first few years, things didn’t appear too promising. Early microwaves were quite expensive and they were big and chunky, so it was difficult to fit them in most kitchens. Yet, people did see the benefit an ease of being able to cook foods so quickly. Therefore, once manufacturers were able to shrink the device and bring down the price a bit, sales started to skyrocket. By 1986, approximately 25 percent of Americans had a microwave oven in their kitchen. Through the years, many people have questioned the safety and potential negative health effects of microwaves, fearing that the technology was a little too good to be true. Yet, some studies have shown that microwaving food actually helps it to retain more nutrients because of the short cooking times and minimal water required. However, it is essential to use microwave containers to avoid harmful chemicals from possibly leaking into your food. Microwave dishes may never be seen as gourmet cooking, but when you are in a hurry, nothing beats this method of cooking.

Explosions in the Sky
If you attend a major outdoor event in the evening, whether it is in Paris, Beijing, or New York City, there is a good chance that it will end in a sensational way. After all of the other activities have concluded, the sky will be lit up by a colourful firework display. Although the show may only last for a few minutes, during that time every eye will look on with amazement as they work their magic in the air. Fireworks were invented in the seventh century by the Chinese. They were quickly absorbed into the culture and became a part of many celebratory events and festivals. Eventually, emperors would organize large firework displays to entertain and impress their subjects. Fireworks didn’t become big in Europe until the mid-17th century. People became interested in fireworks after reading accounts from monks and travellers who saw them while in China. Once they did arrive, it was obvious they were there to stay. Fireworks were frequently paired with triumphant classical symphonies to celebrate the end of wars and other great victories. As time went on, the fireworks continued to evolve and get better in many ways. Fireworks now come in every colour imaginable. The colour comes from different chemicals that are placed inside of each firework. Thanks to modern technology, it is also possible to create firework arrangements in the shape of hearts, smiley faces, and even the planet Saturn. This is because of the way that the aerial shells, or casings, of fireworks are constructed. The cases are packed with exploding pellets and a piece of cardboard. The cardboard enables the designers to arrange the pellets in pattern or shape of the object of their choice. The first time this technology was used was in Washington DC, during a celebration to welcome home American troops who fought in the Gulf War. The visual aspect is only part of the reason fireworks are appealing. The sounds that fireworks make also add a healthy dose of excitement to the display. There are several noises that fireworks can make. The most common is the “bang” which sounds a lot like a gunshot. Fireworks can also crackle, hum, and whistle as they streak across the night sky. The world’s largest firework show was held in Kuwait in 2012. 77,282 fireworks exploded during the incredible 64-minute show. But with people’s love for fireworks at an all-time high, who knows how long that record will last?

Read the following passage and choose the best answer (A, B, C, D):
Even before the turn of the century, movies began to develop in two major directions: the realistic and the formalistic. Realism and formalism are merely general, rather than absolute terms. When used to suggest a tendency toward either polarity, such labels can be helpful, but in the end they are still just labels. Few films are exclusively formalist in style, and fewer yet are completely realist. There is also an important difference between realism and reality, although this distinction is often forgotten. Realism is a particular style, whereas physical reality is the source of all the raw materials of the film, both realistic and formalistic. Virtually all movie directors go to the photographable world for their subject matter, but what they do with this material, how they shape and manipulate it determines their stylistic emphasis. Generally speaking, realistic films attempt to reproduce the surface of concrete reality with a minimum of distortion. In photographing objects and events, the filmmaker tries to suggest the copiousness of life itself. Both realist and formalist film directors must select and hence emphasize certain details from chaotic sprawl of reality. But the element of selectivity in realistic films is less obvious. Realists, in short, try to preserve the illusion that their film world is not manipulated, an objective mirror of the actual world. Formalists, on the other hand, make no such pretense. They deliberately stylize and distort their raw materials so that only the very naive would mistake a manipulated image of an object or event for the real thing. We rarely notice the style in a realistic movie; the artist tends to be self-effacing. Some filmmakers are more concerned with what is being shown than how it is manipulated. The camera is used conservatively. It is essentially a recording mechanism that reproduces the surface of tangible objects with as little commentary as possible. A high premium is placed on simplicity, spontaneity, and directness. This is not to suggest that these movies lack artistry, however, at its best the realistic cinema specializes in art that conceals art.

I was brought up in a very ordinary but very happy home with one elder sister, my mother and my father. The great love of my life since I was a small girl was writing, which only family thought was surprising because they didn't consider themselves educated people. I wasn't surprised though because my parents were great readers which is my idea of being educated. Anyway, I trained to be a nurse but whenever I had free time I wrote: poems, short stories, I even once wrote a novel called 'The Pleasure Principle' but I didn't feel comfortable writing longer pieces and I soon went back to my poetry. 
Then the strangest thing happened. I had my twenty-first birthday just a few days before and I was feeling very much that I wanted to change things in my life. I'd been nursing a very old woman for several months in a private ward, she told me that although she had-lots of relatives, no one came to visit her. Anyway, when she died she left me an enormous sum of money, nearly three-quarters of a million pounds! Of course when the lawyer rang me up and told me I just laughed and thought that my friends were playing a joke on me. So I put down the phone and went in to tell my mother the joke. 
But it wasn't a joke! All of a sudden, I was a very rich woman. Well, the first thing was that I was determined that I wouldn't waste the money. Of course I wanted to do something for my family, but all my dad said was 'We're not leaving this house after all the work I've put into the garden!' My mother agreed so all I did was give them something towards a new car and a new greenhouse. My sister was working abroad at this time and when I wrote to tell her the news and offer her some money she said it was my money and that she knew I would use it sensibly. None of this really came as a surprise because they've always had a sensible attitude towards money. 
But this left me a fortune on my hands to spend! It soon became obvious to me that much as I loved nursing, I loved writing more and that's how I got started. I went to America and did a degree in creative writing. I had a wonderful time and learned a great deal, not from the lecturers necessarily but mainly from other hopeful writers on the course. All this was a decade ago and I've now had several volumes of poetry published. I now want to do something to help other young poets so I'm thinking of setting up a small publishing company which I'll call Grace Park Books after the wonderful old lady who helped me fulfill my life's ambition!

The Power of Crowdsourcing
There is a famous old saying that when trying to solve a problem “two heads are better than one”. Yet until recently, businesses would often rely on one key person to get important tasks done. But thanks to a phenomenon called crowdsourcing, more and more companies are allowing their consumers to have their say when designing new products. The term “crowdsourcing” refers to the process of outsourcing jobs which were once done by a single person to a large group (or a crowd) of people. In the past, crowdsourcing wasn’t practical, as it was impossible to gather thousands of like-minded people together to share opinions. Now, thanks to the Internet, online forums, and social media, this isn’t a difficult task at all. There are many important applications for crowdsourcing in business. For example, if a small business was looking to develop a business logo, it might employ a single designer and hope for the best. However, with crowdsourcing, companies can specify some guidelines about their project, set a budget, and start a design contest online. Within hours, it will likely receive hundreds of designers sending them logos. In the end, they can choose the design they like best and the winner will get compensated. Crowdsourcing has other applications as well. A website called Duolingo is using crowdsourcing to translate documents into different languages. It offers free lessons to language learners. As part of their tests, users translate lines to test their knowledge. Then, a computer programme will analyze thousands of test results for consistency and arrange an accurate translation. Not everyone is sold on crowdsourcing, though. In many cases, it may be better to rely on the opinion of a few specialized professionals than information from a crowd. For instance, it makes more sense to trust the opinion of one top doctor than to take the advice of 1,000 random people regarding a health issue. Another criticism is the low wage that crowdworkers usually receive. Since crowdworkers are freelancers and not employees, they can be paid less than minimum wage. Whether you love or hate crowdsourcing, it appears to be here to stay. So before you make any financial judgements, consider following the crowd and give crowdsourcing a try.
