Bitcoins are a form of virtual currency. In other words, they are a type of money that does not exist in the actual world. However, they can be used to purchase actual products and services from real companies. 2. The bitcoin system was created in 2009 by an enigmatic person named Satoshi Nakamoto. In fact, no one is sure if Satoshi Nakamoto is an actual person or a group of people. Bitcoins are designed to serve as an alternative to national currencies, such as dollars and euros. They can be used to pay for things online instead of cash or credit cards. When bitcoins are transferred from a buyer to a seller, the transaction is recorded in a public database. 3. Governments are concerned that bitcoins can easily be stolen by hackers. It has dawned on them that they might be used for illegal purposes. For example, stolen goods could be purchased without the government\u2019s knowledge. Although more and more companies are beginning to accept bitcoins, the percentage of purchases made using bitcoins is minuscule compared to other online payment methods, such as credit cards. Instead, many bitcoin owners simply keep them as an investment since they believe their bitcoins will be more valuable in the future. 4. This may or may not be a wise approach. Currently, the value of bitcoins is fluctuating wildly, especially when compared to highly stable national currencies. Bitcoin investors are gambling on the hope that as this high-tech money becomes more widely accepted, its value will soar. (Adapted from: https:\/\/www.digitalcommerce360.com\/) Choose an option (A, B, C or D) that best answers each question. 36. Why are bitcoins of great concern to governments? A. Because most of bitcoin owners are hackers. B. Because bitcoins may be used in illegal transactions. C. Because the value of bitcoins is fluctuating wildly. 57 \/ 407","D. Because bitcoins will eventually replace national currencies. 37. What is the passage mainly about? A. The future of bitcoins in the real world B. A new kind of currency in the virtual world C.

An estimated 18,000 people die every day worldwide as a result of air pollution. The great majority of the world's population breathe air that does not meet World Health Organization guidelines. Air pollution has become so bad that it's said we now have a \u201cfifth season\u201d: this time of year, when lethal smogs envelop some of the most populated parts of the world. Delhi's atrocious smogs, which caused an international cricket match to be halted on Sunday, follow similar ones last year. 2. But 65 years on from the toxic Great Smog of London that descended on 5 December 1952, and led to ground-breaking anti-pollution laws being passed, the air above the UK still hasn\u2018t cleared. In London alone more than one person an hour dies prematurely from a range of conditions such as congestive heart failure, asthma and emphysema as a result of exposure to particulate matter and nitrogen dioxide. The mayor of London, Sadiq Khan, has called for a new Clean Air Act that would enshr ine a right to clean air. 3. Smog Day marks the anniversary of the Great London Smog, and the middle of the international smog season. It grew out of an initiative to share the experiences of people living with air pollution in London and New Delhi, whose air quality is among the worst in the world. In spite of many differences between life in the two capital cities, there are parallels in the experiences of people who work on the streets, runners who exercise along them, taxi drivers, parents and children and the doctors who care for those with breathing difficulties. 4. Progress on air pollution is already being made in many places around the world. The recent Lancet Commission on pollution and health points out that air-quality improvements not only save lives, but have other benefits. Choose an option (A, B, C or D) that best answers each question. 36. What is the main idea of the passage? A. Successful efforts in making the air less polluted. B. The comparison of air pollution levels between two big cities. 77 \/ 407","C. How serious air pollution is worldwide. D. What Smog Day in London is. 37. What can be inferred about the \u201cfifth season\u201d? A. It is the last season of the climatic pattern in a year. B. During this time outdoor sports games may be cancelled. C. During this time, lethal smogs attack almost any places in the world. D. It is the result of overpopulation. 38. Which word is closest in meaning to the word \u201censhr ine\u201d in paragraph 2? A. prevent B. improve C. maintain D. authorize 39. Which statement is NOT true of London and New Delhi? A. People from these cities share the same experience of breathing difficulties. B. People who work on the streets in these cities share the same experience. C. Air quality in these cities is among the worst. D. These two capital cities are not completely alike. 40. Compared to London in 1957, London now . A. has better air quality. B. has fewer laws passed. C. sees an increase in nitrogen dioxide. D. has unchanged air pollution level PH\u1ea6N 2.

Question 36 \u2013 40: Read the passage carefully. Almon Strowger, an American engineer, constructed the first automatic telephone switching system, which had a horizontal, bladelike contact arm, in 1891. The first commercial switchboard based on his invention opened in La Porte, Indiana, a year later and was an instant success with business users. To access the system, the caller pressed button to reach the desired number and turned the handle to activate the telephone ringer. During the same year, Strowger\u2019s step-by-step call advancement technology was implemented in the long-distance service between New York and Chicago when it proved to have the capacity of carrying signals through cable-joint extensions. 96 \/ 407","The first actual dial telephone, patented by Lee De Forest in 1907, was installed in Milwaukee in 1906. In 1912, their sound transmittal apparatus adapted an electronic tube to function as an amplifier. Transatlantic radio-telephone service linked New York and London in 1927. However, the long distances coaxial cable, which was hailed as unprecedented, came on the scene in 1936 connecting New York and Philadelphia. The Bell Laboratories research facility came up with the transistor to replace the cumbersome vacuum tube, thus diminishing the size of the electronic switch system to about 10 percent of that of the original. Crossbar switching, installed in terminals in 1938, operated on the principle of an electromagnetic force, which rotated horizontal and vertical bars within a rectangular frame and brought contacts together in a split second. A technological breakthrough in the form of undersea cables between the United States and Hawaii was implemented almost twenty years later. An extension was connected to Japan in 1964. Choose an option (A, B, C or D) that best answers each question. 36. Which of the following would be the best title for the passage? A. The Patent History of the Telephone B.
