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 is NOT mentioned as an advance in short-range weather forecasting?

Read the following passage about Innovation Driven by Environmental Need 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 startups have emerged as forces for positive environmental change. These companies create sustainable solutions for urgent ecological challenges. Unlike traditional businesses prioritizing profits, green startups balance financial goals with environmental responsibility. Many were founded by young entrepreneurs who witnessed environmental degradation and felt compelled to act. Their mission extends beyond making money; they aim to heal our planet while building successful businesses.

Eco-friendly startups have grown across various sectors. From renewable energy and sustainable agriculture to zero-waste products, these companies revolutionize how we interact with our environment. GreenWave developed ocean farming requiring no fertilizers while capturing carbon. Notpla created edible packaging from seaweed as a plastic alternative. These innovations show how creativity and environmental consciousness produce extraordinary results. Their success proves sustainability and profitability can coexist.

Funding for green startups has increased in the past decade. Investors recognize supporting environmentally responsible businesses is both ethical and financially prudent. Venture capitalists have established funds dedicated to sustainable startups, providing capital to scale operations. Government grants have become more accessible to entrepreneurs developing green technologies. Despite positive developments, green startups still face regulatory hurdles and competition from established industries resistant to change.

The future looks promising for environmental businesses as consumers shift toward sustainable products. Studies show modern consumers, particularly younger generations, will pay premium prices for eco-friendly alternatives. This trend creates fertile ground for green startups to thrive. As climate concerns intensify, demand for innovative environmental solutions will grow stronger. Green startups are positioned to meet this demand while driving positive change, demonstrating business innovation and environmental stewardship can create a sustainable world.

In which paragraph does the writer mention green startups are working in many different industries with impressive innovations?

Read the following passage about beginning a lifelong journey 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.

Lifelong learning is the continuous pursuit of knowledge and skills throughout a person's life. In today's world, where technology is evolving rapidly, lifelong learning is essential for both personal growth and career development. But just how does one go about becoming a lifelong learner?

The first step in becoming a lifelong learner is to develop a growth mindset. This means believing that your abilities can be developed through hard work, dedication and commitment. Embrace challenges, view mistakes as opportunities to learn, and be open to new ideas and perspectives. Adopting a growth mindset will help you approach learning with a positive attitude and a desire to improve.

Setting achievable goals is also an important part of lifelong learning. Goals give direction and motivation to your learning journey. First, identify areas of interest and choose specific skills or knowledge that you want to develop. Second, break your goals down into smaller, more manageable tasks and track your progress. Finally, celebrate your accomplishments along the way to stay motivated.

People learn in different ways, so it's also essential that you find the methods that work best for you. You can do this by trying out a variety of different learning methods, such as reading, watching videos, attending lectures and engaging in hands-on practice. At the same time, you should also experiment with different learning tools and techniques until you find what works best for you. Becoming a lifelong learner is a continuous process that requires dedication and effort. Developing a growth mindset, setting achievable goals, and using a variety of learning methods are essential steps to becoming a successful lifelong learner. By embracing learning as a lifelong journey, you will continue to grow, develop new skills, and stay relevant in today's ever-changing world.
