Air pollution is a significant environmental issue that affects millions of people worldwide. It results from various sources, including industrial emissions, vehicle exhaust, and the burning of fossil fuels. [I] Among the most harmful pollutants are fine particulate matter (PM2.5), carbon monoxide, sulfur dioxide, and nitrogen oxides. These pollutants not only degrade air quality but also have serious health consequences, such as respiratory diseases, cardiovascular problems, and even premature death. [II]
In major cities, traffic congestion plays a critical role in worsening air pollution. The high concentration of vehicles, particularly those running on diesel fuel, releases large amounts of pollutants into the atmosphere. [III] Additionally, industrial activities in urban areas contribute to the problem by emitting harmful gases and chemicals. [IV]
Governments and environmental organizations have been implementing various measures to combat air pollution. These include promoting the use of renewable energy, encouraging public transportation, and imposing stricter emission regulations on industries. Moreover, advancements in technology have led to the development of electric vehicles and air purification systems, which help reduce pollution levels. However, despite these efforts, achieving clean air remains a global challenge that requires cooperation from all sectors of society.
According to paragraph 2, which of the following is NOT mentioned as a cause of air pollution?

Climate Change and Its Impacts on Earth
Our Earth remains breathtakingly beautiful. The sky is blue, clouds are fluffy, the wind blows gently, and rain continues to fall. This serene image of our planet is something we all cherish. Yet, behind this calm and majestic exterior, undeniable evidence points to rapid and alarming environmental changes. Scientists around the world have observed that climate change and global warming are accelerating at a rate never before seen in Earth's long history.
Global warming poses a serious and significant threat to the health of our planet and all living beings that call it home. Over the last century, the average surface temperature of the Earth has risen by nearly 1.5 degrees Fahrenheit. At first glance, this might seem like a minor rise, but its impact has been far-reaching and profound, altering the delicate balance of the global climate. Recent data reveals that 11 out of the past 12 years were the hottest on record, emphasizing how quickly warming has advanced in just a few decades.
The consequences of this warming are becoming increasingly apparent. Polar ice caps and glaciers are melting at unprecedented rates, leading to rising sea levels that endanger coastal cities and small island nations. Meanwhile, extreme weather events—such as prolonged droughts, catastrophic floods, and violent storms—are becoming not only more frequent but also more severe. These changes are disrupting human lives, threatening agricultural systems, and putting countless ecosystems and species at risk of extinction.
To combat this crisis, everyone must take responsibility. Simple actions, such as reducing carbon emissions, adopting renewable energy, and conserving natural resources, can make a significant difference. Addressing climate change requires collective effort and immediate action to prevent its impacts from worsening. By working together, we can protect our planet and create a sustainable future for generations to come.
According to the passage, which of the following statements is TRUE?
Read the following passage about education in Nepal 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.
A few years ago, amid a record drought, scientists noticed something odd. A few of California’s giant sequoias inside Sequoia and Kings Canyon National Parks were dying in ways no one had ever documented – from the top down. When researchers climbed into the canopies, they discovered that beetles had bored into a few branches. By 2019, at least 38 of the trees had died – not a large number, but "concerning because we’ve never observed this before,” says Christy Brigham, the park’s chief of resource management.
Scientists had assumed that stately sequoias, with their bug-repelling tannins, were immune to dangerous pests. Worried experts are investigating whether some mix of increased drought and wildfire, both worsened by climate change, have now made even sequoias susceptible to deadly insect invasions.
If so, these ancient sentinels would be just the latest example of a trend experts are documenting around the world: Trees in forests are dying at increasingly high rates—especially the bigger, older trees. According to a study in the journal Science, the death rate is making forests younger, threatening biodiversity, eliminating important plant and animal habitat, and reducing forests’ ability to store excess carbon dioxide generated by our consumption of fossil fuels. [A]
There is no single direct cause. Decades of logging and land clearing play a role, scientists say. But increasing temperatures and rising carbon dioxide from the burning of fossil fuels have significantly magnified most other causes of tree death. Scientists are documenting longer and harsher droughts, more severe outbreaks of insects and disease, and increasingly catastrophic wildfires.
With 60,000 known tree species on Earth, those shifts are playing out differently across the planet. In central Europe, for instance, “You don’t have to look for dead trees,” says Henrik Hartmann, with Germany's Max Planck Institute for Biogeochemistry. “They’re everywhere.” In one recent year, following a week of excessive heat, hundreds of thousands of beech trees dropped their leaves. Even in colder regions, “You get a couple of hot years and the forests are suffering,” says Hartmann. “There are individual species that are being driven beyond the threshold of what they can handle.” [B]
Just last year, massive fires marched through a dry Australia, smoldered across 7.4 million acres in northern Siberia, and focused the world’s attention on blazes in the Amazon.
The consequences of all these changes around the world are still being assessed. The first national look at tree mortality in Israel showed vast stretches disappearing, thanks largely to scorching heat and wildfires. [C] In a country largely blanketed by stone and sand, forests mean a great deal. Trees support nests for eagles and habitat for wolves and jackals. They hold soil with their roots. [D]
“We’re dealing with a very tough situation. It’s a race to the unknown,” says Tamir Klein at the Weizmann Institute of Science.
In the first paragraph, why does Christy Brigham say the death of 38 trees is concerning?

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 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.

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.

Read the following passage about Asia’s culture and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions
[I] Chemicals are present everywhere in our environment, some of which occur naturally, while others are the result of human activities. [II]. They are found in the air, water, and soil, and can have both positive and negative impacts on the ecosystem. Some chemicals, like nutrients, help support life by promoting plant growth [III]. However, others, especially synthetic chemicals such as pesticides, fertilizers, and industrial waste, can be harmful to both the environment and human health. [IV]
The widespread use of pesticides and fertilizers in agriculture has been a major cause of chemical pollution. When these chemicals are used improperly or excessively, they can wash into rivers, lakes, and oceans, leading to water pollution. This runoff can also contribute to the depletion of oxygen in water bodies, a process known as eutrophication. Eutrophication harms aquatic life, disrupting ecosystems and causing the death of fish and other organisms that rely on oxygen.
Toxic chemicals such as heavy metals (e.g., mercury and lead) pose additional threats to the environment and human health. These substances can accumulate in the food chain, starting from plants and animals in contaminated areas and eventually reaching humans.
