Read the following passage about Global Challenges Requiring Diverse Solutions and mark the letter A, B, C or D on your answer sheet to indicate the option that best fits each of the numbered blanks from 18 to 22.

Climate change affects everyone on our planet, but different communities experience its impacts in unique ways. (18)_________. This traditional wisdom, which connects deeply with nature, can help us find better solutions to environmental problems. If we had started addressing climate change earlier, many environmental disasters could have been prevented. The effects of global warming are now visible in many regions around the world, from melting ice caps to increasing droughts and floods. These changes threaten not only ecosystems but also cultural practices tied to specific environments. Many coastal communities (19)_________, and ancient cultural sites are being damaged by extreme weather events. When diverse communities work together, sharing their unique perspectives and knowledge, innovative climate solutions emerge. Different cultural approaches to agriculture, water conservation, and energy use can inspire new ways of thinking about sustainability. Climate solutions must be culturally appropriate; (20)_________. By combining traditional wisdom with modern science, we create more effective strategies for addressing climate challenges. Communities around the world are already implementing these multicultural approaches, demonstrating (21)_________. People want immediate action on climate change; however, governments often move slowly on environmental policies. Scientists study climate patterns and develop new technologies, (22)_________. The path forward requires collaboration across cultures, disciplines, and borders. Only through inclusive dialogue and shared responsibility can we build a sustainable future that honors both human diversity and our common home.

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.

Which of the following best paraphrase this sentence:

“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.”
