Read the following passage about green living 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 23 to 30

          Green living refers to a lifestyle that promotes sustainability and environmental consciousness. This way of life encourages individuals to make choices that reduce their carbon footprint and conserve natural resources. Practices such as recycling, using renewable energy sources, and reducing waste are fundamental aspects of green living. By adopting these practices, individuals can contribute to the preservation of the environment and promote a healthier planet for future generations.

          One significant component of green living is the use of renewable energy sources. Solar, wind, and hydroelectric power are examples of renewable energy that can replace fossil fuels. Using renewable energy reduces greenhouse gas emissions and dependence on non-renewable resources. Additionally, renewable energy sources are often more sustainable and have less impact on the environment.

          Another important aspect of green living is sustainable consumption. This involves choosing products that are environmentally friendly and responsibly sourced. For example, buying locally produced food reduces the carbon footprint associated with transportation. Moreover, opting for products made from recycled materials helps conserve resources and reduce waste.

          Green living also emphasizes the importance of conserving water and energy. Simple actions such as turning off lights when not in use, fixing leaks, and using energy-efficient appliances can significantly reduce energy and water consumption. These practices not only benefit the environment but also save money on utility bills.

          Education and awareness play a crucial role in promoting green living. By educating individuals about the benefits of sustainable practices and how to implement them, communities can foster a culture of environmental responsibility. Awareness campaigns, workshops, and educational programs are effective ways to encourage people to adopt green living practices.

The word "conserve" in paragraph 3 could be best replaced by:

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.”
