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 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.

[I] Landslides are a significant environmental challenge in the northern mountainous provinces of Vietnam, partiCularly during the rainy season. The region, characterized by steep slopes and heavy rainfall, is prone to this natural disaster, which poses serious threats to both the local population and infrastructure. [II] ln recent years, numerous landslides have occurred, often triggered by prolonged periods of heavy rain, resulting in devastating impacts on communities and livelihoods.

The mountainous terrain, combined with deforestation and improper land use, exacerbates the risk of landslides. [III] As farmers clear forests for agriculture, the natural vegetation that stabilizes the soil is lost, making slopes more susceptible to erosion. When heavy rains saturate the soil, it can quickly become unstable, leading to sudden and destructive landslides. [IV]

In response to this growing threat, local authorities and environmental organizations are taking proactive measures to mitigate the risks associated with landslides. Efforts include reforestation projects, improving drainage systems, and raising public awareness about safe practices du ring the rainy season. Additionally, advanced monitoring systems are being implemented to provide early warnings, allowing communities to evacuate before a disaster strikes.

Despite these efforts, the challenges remain significant, and ongoing education and support for sustainable land management practices are crucial for reducing the incidence and impact of landslides in northern Vietnam.

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.

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.

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 and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 31 to 40.

Sustainable development has become a priority worldwide, as nations work to balance economic growth with environmental preservation. [I] Sustainable practices are critical to ensure that natural resources are conserved for future generations, while also meeting today’s economic needs. [II] Many countries have invested in green technologies to reduce carbon emissions and slow climate change.

[III] However, achieving sustainability involves more than just technology; it requires a collective shift in mindset towards reducing waste, reusing materials, and protecting biodiversity. [IV] According to the United Nations, sustainable development must incorporate social equity, economic progress, and environmental stewardship to be effective.

A key factor driving sustainability efforts is the awareness of limited resources. The earth’s resources, such as freshwater, fossil fuels, and fertile land, are finite, and overuse can lead to scarcity. In recent years, many nations have implemented regulations to control the extraction and consumption of resources, aiming to curb excessive demand and reduce environmental impact. For example, many cities have introduced restrictions on single-use plastics and have promoted recycling programs as a means to encourage responsible waste management.

While developing countries may prioritize industrial growth to boost economic development, developed nations often focus on reducing their carbon footprint and promoting eco-friendly policies. This disparity can lead to challenges in international relations, as countries negotiate agreements on emissions and resource use. Organizations like the United Nations work to bridge these gaps through global frameworks that encourage cooperation, but disparities in priorities and resources can hinder progress.

Increasing public awareness about environmental sustainability has been another critical component of these efforts. Through education and media campaigns, individuals are encouraged to adopt environmentally conscious practices, such as reducing energy consumption, using public transport, and supporting local economies. By making small adjustments in daily life, individuals contribute to broader global sustainability goals, ultimately promoting a healthier planet for future generations.

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.

Which of the following is NOT a factor in the transportation of heat from the tropics?
