Read the passage below and choose A, B, C or D to answer each question from 636 - 640.

Many of the most damaging and life-threating types of weather-torrential rains, severe thunderstorms, and tornadoes-begin quickly, strike suddenly, and dissipate rapidly, devastating small regions while leaving neighboring areas untouched. One such event, a tornado, struck the northeastern section of Edmonton, Alberta, in July 1987. Total damages from the tornado exceeded $250 million, the highest ever for any Canadian storm. Conventional computer models of the atmosphere have limited value in predicting short-live local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to discern the subtle atmospheric changes that precede these storms. In most nations, for example, weather balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events.

Until recently, the observation-intensive approach needed for accurate, very short range forecasts, or “Nowcasts”, was not feasible. The cost of equipping and operating many thousands of conventional weather stations was prohibitively high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were insurmountable. Fortunately, scientific and technological advances have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost. Communications satellites can transmit data around the world cheaply and instantaneously, and modern computers can quickly compile and analyzing this large volume of weather information. Meteorologists and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is becoming a reality.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 20 to 27.

Traditional Media

Before the invention of newspapers, the main source of news was word of mouth. Any writings and drawings were done by hand. Although printing presses had existed in eastern Asia, it was Gutenberg’s invention in Europe in 1453 that made printing faster and books more accessible. It reduced the cost and size of printed books and made them the first form of mass media affordable to less wealthy people. Gutenberg’s invention also quickened the spread of discoveries and information, and promoted literacy in Europe.

The printing press led to the rise of printed newspapers that appeared regularly. The first newspapers developed from around 1612 and in a short period of time, they became very popular in Europe and the European colonies. In the 19th century, they also appeared in Asia.

Newspapers and magazines are still very popular today. Although most of them have online versions, many people continue to read print media, which is considered more credible than digital media.

In the 1920s, when radio, television, and video were introduced, the phrase “the media” began to be used. Black and white television quickly became popular in the 1950s, and in the 1960s colour broadcasts started in many countries. Thanks to its audiovisual presentation, television became one of the most important forms of mass media in the 20th century. As a source of news, entertainment, and education, it still attracts a large number of viewers today.

The origins of popular foods often reveal surprising historical insights. (18)______. While many assume that curry was introduced to England through interactions with India in the 1600s, historical evidence suggests otherwise. Wealthy English families,(19)______, were consuming dishes prepared with curry spices as early as the time of King Richard I. Notably, the term “curry” appears in an English cookbook published in 1377, long before British ships traveled to India. This early mention highlights how food traditions can transcend borders and evolve over centuries, influenced by trade and exploration.

Similarly, pizza, a dish frequently associated with Italian cuisine, (20)______. While modern pizza originated in Naples, records indicate that in the 500s, Persians consumed round, flat bread topped with cheese. This precursor to the pizza we know today reflects the global interconnectedness of culinary traditions, where simple yet innovative recipes emerge in different cultures independently. (21)______.

The history of hamburgers also deviates from common perceptions. While widely regarded as an American culinary creation, (22)_______. According to historical accounts, Otto Kuasw created the first hamburger in 1891, and by 1895, German sailors had introduced the dish to the United States. This journey from Germany to the U.S. demonstrates how cultural exchanges shape iconic dishes.

Understanding the origins of these foods enhances appreciation of their cultural and historical significance. Regardless of their provenance, their enduring appeal lies in their taste, adaptability, and ability to bring people together across time and space.
