Read the following passage and choose the best answer to each of the following questions from 23 to 30.

APPLICATIONS OF AI IN URBAN PLANNING AND DEVELOPMENT

1. AI is transforming cities, making them smarter, more sustainable, and efficient. By integrating AI into urban planning, cities can operate more smoothly, enhancing the lives of those who live and work there. Key areas where AI can have a significant impact include digital twin technology, smart infrastructure, and optimizing transportation systems.

2. Digital twins are virtual versions of real cities created using data from sensors and devices. These digital models help city planners understand how a city works in real-time. Planners can test different ideas and plans in a virtual space before making changes in the real world. AI helps predict the outcomes of these tests, so the best solutions can be chosen. This saves time, resources, and reduces the risk of making mistakes. It also helps reduce the impact of changes like adjusting traffic flow or modifying energy use.

3. AI is also crucial for reducing the carbon footprint in urban environments, which is key to building sustainable cities. AI-driven platforms can optimize energy use, manage energy grids efficiently, and improve waste management systems. For instance, AI can predict when maintenance is needed, allowing problems to be fixed before they disrupt services. Smart grids can integrate renewable energy sources and optimize the way energy is distributed, minimizing waste and pollution. These solutions are leading the way to a low-carbon future, helping cities meet their net-zero emissions goals.

4. AI is also improving transportation in cities. By analyzing traffic data, public transport schedules, and pedestrian movement, AI helps optimize traffic flow and make public transport more reliable. Traffic lights become smarter, buses run on time, and pedestrian safety is improved. These improvements reduce traffic congestion and make cities more livable for everyone.

Read the following passage about environmental pollution 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.

Since the early 1980s, people have become more aware of the serious effects of large-scale pollution on the environment. This kind of pollution often happens because of poor planning in developing countries or the short-sighted policies of some industrialized nations. These countries use up a large portion of the world’s natural resources, even though only a small part of the world’s population lives there.

Events like the Great Smog of London, the destruction of the Amazon rainforest and the nuclear accident at Chernobyl have received a lot of media attention, as have other acts that harm the environment. However, it’s important to remember that not all pollution is on such a large scale. In fact, a lot of pollution comes from sources closer to home. For instance, a recent oil spill from a tanker in Sydney accidentally released oil into the harbor. This not only damaged the surrounding area but also created toxic fumes that hung over the nearby suburbs for days, leaving residents frustrated and questioning how such a disaster could happen.

Protecting ourselves from pollution can feel like a never-ending task. We try to avoid breathing in traffic fumes, stay away from industrial areas, and wear masks when cycling. All of this might make some people feel safest at home. However, new research shows that staying indoors is not always better. Studies indicate that levels of harmful gases, dust, and other chemicals are often higher indoors than outdoors, even in polluted cities. Since most people spend more time inside than outside, some experts think we may need to pay more attention to indoor pollution to improve public health.

In conclusion, awareness of environmental pollution has grown since the 1980s due to major incidents and local sources of harm. While large-scale events like Chernobyl capture attention, everyday issues, including indoor pollution, also pose serious health risks. Addressing both is vital for public health and environmental protection.

Which of the following is NOT mentioned as one of events recieving a lot of media attention?

Read the following passage about climate change 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 31 to 40.

           Climate change refers to the long-term alteration of temperature and typical weather patterns in a place. This phenomenon is largely driven by human activities, particularly the burning of fossil fuels such as coal, oil, and gas, which increase the concentration of greenhouse gases in the atmosphere. They trap heat from the sun, leading to global warming and causing severe weather events, such as hurricanes, floods, and droughts, to become more frequent and intense. Climate change impacts nearly every region of the world and affects the natural environment, economies, and human health.

           As temperatures rise, polar ice caps and glaciers are melting at alarming rates, contributing to rising sea levels. Coastal regions face an increased risk of flooding, and many low-lying islands are at risk of disappearing entirely. Additionally, higher temperatures lead to the warming of oceans, affecting marine ecosystems and causing coral bleaching, which threatens biodiversity and the livelihoods of millions of people who depend on fishing.

            [I] The consequences of climate change are not just environmental; they also affect human society in significant ways. [II] Changes in weather patterns disrupt agriculture, leading to crop failures and food shortages in vulnerable regions. [III] Furthermore, climate change is linked to health issues such as respiratory diseases, heat strokes, and the spread of diseases carried by insects, like malaria and dengue fever. [IV]

           To combat climate change, a coordinated global effort is necessary. Governments, organizations, and individuals all have roles to play in reducing greenhouse gas emissions and promoting sustainable practices. Shifting to renewable energy sources, such as wind, solar, and hydropower, is essential. Additionally, conserving forests and investing in technology that captures carbon dioxide from the atmosphere can help mitigate the effects of climate change and pave the way for a healthier planet.

Which of the following best summarizes paragraph 4?

Read the following passage about Heat Transfer in the Atmosphere 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 31 to 40.

Because the low latitudes of the Earth, the areas near the equator, receive more heat than the latitudes near the poles, and because the nature of heat is to expand and move, heat is transported from the tropics to the middle and high latitudes. Some of this heat is moved by winds and some by ocean currents, and some gets stored in the atmosphere in the form of latent heat.

(I) The term “latent heat” refers to the energy that has to be used to convert liquid water to water vapor. (II) We know that if we warm a pan of water on a stove, it will evaporate, or turn into vapor, faster than if it is allowed to sit at room temperature. (III) We also know that if we hang wet clothes outside in the summertime, they will dry faster than in winter, when the temperature is lower. The energy used in both cases to change liquid water to water vapor is supplied by heat - supplied by the stove in the first case and by the Sun in the latter case. This energy is not lost. (IV)  It is stored as vapor in the atmosphere as latent heat. Eventually, the water stored as vapor in the atmosphere will condense to liquid again, and the energy will be released to the atmosphere.

In the atmosphere, a large portion of the Sun’s incoming energy is used to evaporate water, primarily in the tropical oceans. Scientists have tried to pin down this proportion of the Sun’s energy. By analyzing temperature, water vapor, and wind data around the globe, they have estimated the quantity to be about 90 watts per square meter, or nearly 30 percent of the Sun’s energy. Once this latent heat is stored within the atmosphere, it can be transported, primarily to higher latitudes, by prevailing, large - scale winds. Or it can be transported vertically to higher levels in the atmosphere, where it forms clouds and subsequent storms, which then release the energy back to the atmosphere.

Where in paragraph 2 does the following sentence best fit?

“The process of converting liquid water into vapor requires significant amounts of energy.”

Read the following passage about plastic bags 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.

Plastic bags are used by everybody. From a vegetable vendor to a designer store, everyone seems to use them. Even though they are one of the modern conveniences that we seem to be unable to do without, they are responsible for causing pollution, killing wildlife, and using up the precious resources of the Earth.  But, most of us are blissfully unaware of the outcomes that are occurring and will take place in the future.

Every once in a while, the government passes out an order banning store owners from providing plastic bags to customers for carrying their purchases. About a hundred billion plastic bags are used every year in the U.S. alone. The problem is further worsened by the developed countries shipping off their plastic waste to developing countries like India.

Once they are used, most bags go into landfills. Each year, more and more bags are ending up littering the environment. Once they become litter, plastic bags find their way into our waterways, parks, beaches, and streets. About 100,000 animals, such as dolphins, turtles, whales, penguins are killed every year due to these bags. And worse, the ingested plastic bag remains intact even after the death and decomposition of the animal. One of the worst environmental effects is that they are non-biodegradable. No one will live so long to witness the decomposition of plastic!

A tote bag can make a good substitute for carrying groceries and the shopping. You can keep the bag with the cashier, and then put your purchases into it instead of the usual plastic bag. Recycling the bags you already have is another good idea. Plastics are not only non-biodegradable, but are one of the major pollutants of the sea. For a clean and green environment, try to use alternatives to plastic whenever and wherever possible.

The word “outcomes” in paragraph 1 could be best replaced by _________.

In which paragraph does the writer mention the major causes of large-scale pollution?

Read the following passage about the urban shift 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 31 to 40. 

Pollution and Its Global Impact

[I] Pollution is one of the most pressing issues in the modern world, affecting not only the environment but also public health and global economies. [II] While urbanization and industrialization have brought significant progress, they have also introduced severe environmental challenges. [III] Reducing pollution requires a comprehensive approach that includes public awareness, technological innovation, and stricter environmental policies. [IV]

Air pollution is among the most widespread forms of environmental degradation. It stems from emissions by vehicles, factories, and deforestation, leading to harmful effects on both human health and the climate. According to the United Nations, fine particulate matter (PM2.5) causes millions of premature deaths annually. Water pollution, caused by untreated waste, agricultural runoff, and oil spills, destroys marine ecosystems and threatens human water supplies. Similarly, soil pollution—often overlooked—results from pesticides, heavy metals, and industrial waste, severely impacting agriculture and biodiversity.

While governments worldwide have implemented measures to combat pollution, individual action is equally essential. Reducing plastic consumption, opting for sustainable transportation, and recycling waste can significantly lessen environmental harm. Moreover, industries must adopt cleaner production methods, such as renewable energy and green technology. However, these solutions are effective only when paired with robust educational campaigns that encourage people to understand and address pollution’s consequences.

Despite these efforts, the problem persists, especially in developing nations, where economic constraints hinder environmental policies and waste management systems. At the same time, wealthier countries often export waste to poorer regions, exacerbating the issue. Experts stress that international cooperation is essential to tackle pollution on a global scale. Unless all nations contribute, the planet’s resources and ecosystems may face irreversible damage.

The word constraints in the final paragraph most likely means:

Read the following passage about the Exploring The Universe 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 31 to 40.

Science is a vast and fascinating field that seeks to understand the natural world and the universe beyond[I]. It encompasses various disciplines, including physics, chemistry, biology, and astronomy[II]. Each of these areas contributes to our understanding of complex phenomena, [III]. For instance, scientific research has led to significant breakthroughs in medicine, renewable energy, and environmental conservation[IV]. In this essay, we will explore the impact of science on our lives, particularly focusing on space exploration.

One of the most intriguing aspects of science is space exploration. Humans have always looked to the stars, wondering what lies beyond our planet. The launch of satellites and manned missions has allowed us to gather valuable information about the cosmos. For example, NASA's Mars Rover has provided insight into the potential for life on other planets. Through meticulous research and data collection, scientists can analyze soil samples and atmospheric conditions, paving the way for future explorations.

Space exploration also raises critical questions about our existence and the future of humanity. As we continue to advance technologically, the prospect of colonizing other planets becomes more plausible. This endeavor could serve as a solution to the challenges we face on Earth, such as overpopulation and resource depletion. However, ethical considerations must guide these efforts. We must ensure that we do not repeat the mistakes of history, such as the exploitation of natural resources and indigenous populations.

Moreover, scientific advancements have enabled us to develop technologies that enhance our understanding of the universe. Telescopes and space probes allow us to observe distant galaxies, study black holes, and uncover the mysteries of dark matter. Each discovery leads to new questions, further fueling our curiosity and drive for knowledge. The concept of the multiverse, for instance, challenges our understanding of reality and pushes the boundaries of scientific thought.

In addition to exploring the universe, science plays a crucial role in addressing pressing issues on Earth. Climate change, for example, is a significant concern that scientists are actively investigating. Through climate models and data analysis, researchers can predict future trends and propose solutions to mitigate the effects of global warming. Public awareness and education are essential in fostering a collective response to environmental challenges.

As we reflect on the wonders of science, it is clear that its contributions extend far beyond mere knowledge acquisition. Science empowers us to make informed decisions about our health, environment, and future. By fostering a culture of curiosity and critical thinking, we can inspire future generations to continue exploring the unknown.
