• Improve stamina

Complete 3 full passages in 60 mins once a week (mock test format)

What you need to do:
Match a list of headings to the correct paragraphs (A–D, etc.) in the passage. Each heading summarizes the main idea of a paragraph.

Purpose:
To test your ability to understand the general meaning and focus of each paragraph — not just isolated facts.

🧠 The Trick:

• Don’t look for keywords only — look for the main message.

• Ignore small details.

• Read the first sentence and last sentence of the paragraph carefully.

• Often, 1–2 headings are very similar; choose the most general one.
  
  

🧭 Do the questions follow the order of the passage?
❌ No. The headings list does not follow the paragraph order. You must analyze each paragraph one by one and pick the best matching heading from the full list.

In recent years, the popularity of organic farming has increased significantly, particularly in Western countries. Many consumers believe organic products are healthier, safer, and better for the environment. However, scientific research has produced mixed results. Some studies show nutritional benefits, while others argue there is little difference compared to conventional methods. Despite the ongoing debate, organic agriculture continues to expand, supported by government subsidies and rising consumer demand.

📌 Heading Options:
i. Criticism of organic farming’s productivity
ii. Debate over the value of organic produce
iii. The environmental effects of modern farming
iv. Government restrictions on organic subsidies

✅ Correct Heading: ii. Debate over the value of organic produce

💡 Why?

• The paragraph doesn’t just describe what organic farming is — it discusses opposing views (benefits vs doubts) = debate

• Environmental and subsidy ideas are mentioned, but not as the main focus

• The best match reflects the central idea, not side points

Read the paragraph and choose the correct heading.

🧾 Practice Paragraph (Paragraph B)

With the development of e-books and digital reading platforms, many have predicted the end of traditional paper books. Surprisingly, however, physical books remain popular. Surveys suggest readers enjoy the tactile experience of turning pages and the lack of screen fatigue. While digital options offer convenience and portability, printed books still dominate certain markets, such as children's literature and academic texts.

Heading Options:
a. Declining interest in printed books
b. The enduring appeal of traditional books
c. The rise of digital platforms in education
d. Environmental advantages of e-books

📌 Your Task:
Which heading best matches Paragraph B?

✅ Correct Answer: b. The enduring appeal of traditional books

Why this is correct:

• The paragraph acknowledges digital trends but focuses mainly on why traditional books are still preferred.

• Phrases like "physical books remain popular," and "readers enjoy..." support this.

• Option (a) contradicts the main idea.

• Option (c) narrows the topic to education, which is not the focus.

• Option (d) is not discussed at all — making it a trap choice.

What you need to do:
Read a set of statements and decide if each one:

• True – matches the information in the passage

• False – contradicts the information

• Not Given – not mentioned or cannot be confirmed
  
  

🧠 The Trick:

• Match ideas, not just words.

• “True” means the information is exactly stated or clearly implied.

• “False” means the passage says the opposite.

• “Not Given” means the topic might be mentioned, but the specific detail is not.
  
  

🔎 Avoid assumptions — answer based only on the passage.

🧭 Do the questions follow the order of the passage?
✅ Yes. These questions usually follow the same order as the text. This helps you locate answers more efficiently.

🧾 Sample Paragraph:

A recent study revealed that students who sleep at least eight hours per night perform better on memory-based tasks. However, there was no consistent improvement in problem-solving tasks.

1. Students who sleep more than eight hours always perform better on all exams.

2. Sleep helps with remembering information.

3. The study found no link between sleep and problem-solving abilities.

4. Researchers recommend getting at least nine hours of sleep.
   
   

✅ Answers:

1. False – "always" and "all exams" = exaggeration. The passage says only memory tasks improved.

2. True – "sleep boosts memory consolidation" = matches.

3. True – "no consistent improvement in problem-solving" = matches.

4. Not Given – No recommendation about “nine hours” is mentioned.

📄 Reading Passage 1

Before the invention of paper, civilizations relied on various materials to record information. Ancient Egyptians used papyrus—thin sheets made from the pith of the papyrus plant. In other parts of the world, materials such as silk, bamboo, parchment, and clay tablets served as writing surfaces. These methods, while effective for their time, were expensive, labor-intensive, and not ideal for mass communication.

The earliest form of paper as we know it was invented in China during the Han dynasty, around 105 AD, by a court official named Cai Lun. He developed a method using mulberry bark, hemp waste, old rags, and fishnets, all soaked and pulped to form thin sheets. This innovation marked a significant shift in record keeping and communication, offering a more practical, affordable, and scalable solution.

Initially, paper production remained a closely guarded secret within China for centuries. However, in 751 AD, during a battle between Chinese and Arab forces in Central Asia, Chinese papermakers were captured and brought to the Abbasid Caliphate. This event is often credited with the transmission of papermaking techniques to the Islamic world. Baghdad became a hub of paper production by the 9th century, fueling a golden age of Islamic scholarship. The spread of paper accelerated intellectual pursuits, including science, philosophy, and mathematics.

Paper reached Europe much later, around the 11th century, through Spain and Sicily—regions under Islamic influence. The rise of universities and administrative systems in medieval Europe created an urgent need for inexpensive writing materials. Initially, paper faced resistance from scribes who favored parchment and viewed paper as inferior. But as demand grew and techniques improved, paper mills spread throughout Europe.

One of the most transformative moments in paper’s history was its role in the invention of the printing press by Johannes Gutenberg in the 15th century. Gutenberg’s press, combined with the affordability of paper, enabled the mass production of books. This revolutionized education, religious thought, and scientific exchange, laying the foundation for the modern knowledge economy.

Today, while digital alternatives are increasingly common, paper remains integral to daily life, from packaging and currency to education and art. Environmental concerns have prompted innovations in recycled paper and sustainable forestry, ensuring that paper’s legacy continues in a more eco-conscious form.

Advertising is not merely about promoting a product—it is a sophisticated science rooted in psychology. Every slogan, color scheme, font style, and even background music is carefully chosen to influence consumer behavior and decision-making processes. As competition intensifies in global markets, companies increasingly turn to psychological strategies to gain an edge.

One of the most well-known psychological tools in advertising is emotional appeal. Rather than simply listing product features, advertisers often target human emotions such as happiness, nostalgia, fear, or excitement. For example, a commercial for a cleaning product may not just emphasize its efficiency but depict a cheerful family enjoying a clean, safe home. This emotional connection creates a positive association with the brand, making it more memorable and persuasive.

Another key strategy is social proof. Humans are inherently influenced by what others think and do. Advertisements that include customer testimonials, five-star ratings, or phrases like “best-selling” tap into this tendency. Even subtle cues such as showing a product in the hands of a crowd can trigger the belief that it must be popular and trustworthy. Social media influencers have amplified this effect dramatically in recent years.

Color psychology also plays a significant role in consumer perception. Different colors evoke different feelings—red stimulates urgency and passion, often used in clearance sales; blue is seen as trustworthy and calm, frequently chosen by financial institutions. Even the brightness and contrast levels are tested and modified to maximize user response.

Moreover, advertisers exploit the principle of scarcity. When people believe something is limited in availability, they tend to assign it more value. Common phrases like “limited time offer” or “only a few items left in stock” encourage quicker purchasing decisions by tapping into a fear of missing out (often abbreviated as FOMO).

Repetition is another psychological tactic used to increase brand recall. When people hear a message or see a logo repeatedly, it becomes familiar and more acceptable over time—a phenomenon known as the mere-exposure effect. This is why jingles, slogans, and repetitive TV ads often become ingrained in public consciousness.

However, modern consumers are more aware of these strategies than ever before. As a result, ethical advertising has gained attention, especially among younger demographics who value transparency and authenticity. Companies now face the challenge of balancing persuasion with honesty. Overuse of manipulative tactics can lead to skepticism and damage brand trust.

Recent studies in neuromarketing—a field that combines neuroscience and marketing—have revealed deeper insights. Brain scans show that certain types of storytelling in ads activate the same neural circuits involved in empathy and memory formation. A compelling narrative can make a product not just recognizable but emotionally significant.

Despite its many tools, advertising remains an evolving discipline. As digital platforms become more immersive and personalized, advertisers continue to refine their understanding of human behavior. The future of advertising lies not only in visibility but in emotional relevance, cultural sensitivity, and psychological precision.

📄 Reading Passage 3

Geothermal energy, a renewable and sustainable source of power, originates from the natural heat of the Earth’s interior. This heat is produced by the slow decay of radioactive particles in the Earth's core, as well as residual heat from planetary formation. Accessible through hot water reservoirs and steam beneath the surface, geothermal energy offers an environmentally friendly alternative to fossil fuels.

The extraction process typically involves drilling deep wells to tap into underground reservoirs of steam or hot water, which then drive turbines connected to electricity generators. There are three main types of geothermal power plants: dry steam, flash steam, and binary cycle. Dry steam plants draw directly from underground steam sources, while flash steam plants use high-pressure hot water that quickly vaporizes—or “flashes”—into steam. Binary cycle plants, which are the most versatile, use moderate-temperature water to heat a secondary fluid with a lower boiling point, thus producing vapor to turn the turbines.

The advantages of geothermal energy are significant. Unlike solar or wind, geothermal power is baseload, meaning it provides a consistent and stable energy output, unaffected by weather or time of day. It also has a small land footprint, produces very low greenhouse gas emissions, and requires minimal fuel input after installation. Countries with volcanic or tectonically active regions—such as Iceland, the Philippines, and New Zealand—have particularly high geothermal potential.

However, geothermal energy is not without limitations. Its availability is highly location-specific, limiting its global scalability. Additionally, drilling deep wells is both expensive and technically demanding. In some regions, tapping into geothermal reservoirs has been associated with minor seismic activity, raising concerns about induced earthquakes.

Beyond electricity generation, geothermal energy has diverse applications. Direct-use geothermal systems provide heating for homes, greenhouses, and fish farms. In Reykjavik, Iceland, nearly 90% of homes are heated using geothermal water, illustrating its potential for district heating. Another method, called ground-source heat pumping, uses the relatively stable temperature of the upper soil layers for heating and cooling buildings, though this differs technically from deep geothermal systems.

Recent advancements have further increased the efficiency and feasibility of geothermal systems. Enhanced Geothermal Systems (EGS), for instance, artificially create geothermal reservoirs by injecting water into hot, dry rock formations where natural water is absent. While still in experimental stages in many countries, EGS could revolutionize geothermal accessibility and expand its use into regions previously considered unsuitable.

On a global scale, geothermal energy still constitutes a small fraction of the total energy mix. According to the International Renewable Energy Agency (IRENA), geothermal power accounted for less than 1% of global electricity generation as of 2022. However, as countries strive to meet carbon neutrality targets, interest and investment in geothermal technologies are growing.

The scientific community continues to study geothermal systems, not only for energy purposes but also for insights into geological processes and climate change. Understanding subsurface heat flow helps geologists predict volcanic activity and contributes to models of Earth's thermal evolution.

As the world seeks a transition toward cleaner and more sustainable energy sources, geothermal power stands out for its reliability, longevity, and environmental benefits. With the right infrastructure, investment, and research, it may become a cornerstone of future energy strategies.

📄 Passage:

In recent years, urban agriculture has gained momentum as a response to growing concerns about food security, climate change, and population density. Among the most promising innovations in this field is vertical farming — the practice of growing crops in stacked layers, often integrated into urban buildings or dedicated high-tech facilities.

Vertical farming makes use of controlled-environment agriculture (CEA) technology, where factors such as temperature, humidity, light, and nutrients are precisely regulated. This enables farmers to grow produce year-round, unaffected by seasonal changes or outdoor weather conditions. The use of hydroponics or aeroponics — systems that deliver water and nutrients directly to roots without soil — significantly reduces water use compared to traditional farming. In fact, some systems claim to use up to 95% less water than conventional fields.

One of the major advantages of vertical farming is its potential to reduce the carbon footprint associated with food transportation. By producing vegetables and fruits close to where they will be consumed, urban farms can eliminate the need for long-haul logistics. Moreover, with fewer pests and diseases in a controlled indoor environment, reliance on chemical pesticides is greatly diminished.

Despite these advantages, vertical farming faces significant challenges. High initial investment costs for infrastructure, energy consumption for artificial lighting, and technical expertise required to manage complex systems are often cited as barriers to widespread adoption. For instance, while LED lighting is more efficient than traditional options, running these lights continuously contributes to high energy bills — especially in regions with less access to renewable energy sources.

Economically, the industry is still evolving. Large-scale operations such as those by AeroFarms in the United States or Plenty in California have received significant venture capital, but profitability remains elusive for many startups. Some critics argue that vertical farms are best suited for leafy greens and herbs, which have short growth cycles and high market value, but are less effective for staple crops like wheat or rice.

Socially, vertical farming represents a shift in how people view food production. It repositions farming from rural landscapes to urban centers and introduces younger generations to agriculture through technology. Educational institutions and city planners have begun to incorporate vertical gardens in schools, libraries, and office buildings as a way to promote sustainability and food literacy.

As climate unpredictability continues to threaten global agricultural yields, vertical farming may play a critical role in diversifying food sources. In regions with limited arable land or harsh climates, such as the Middle East or densely populated Asian cities, vertical farms can offer a sustainable alternative. However, their long-term success will depend on continued innovation, energy-efficient technologies, and policies that support urban agriculture.

📄 Passage:

In the past, public libraries were considered the primary source of information and education for the general public. Today, however, they face increasing competition from digital platforms offering instant access to e-books, online courses, and multimedia content. Despite these pressures, public libraries have not disappeared. Instead, they are reinventing themselves to remain relevant in the digital age.

Modern libraries have evolved beyond book lending. Many now function as community hubs, offering coworking spaces, digital media labs, and free internet access. In economically disadvantaged neighborhoods, this digital access plays a vital role in bridging the digital divide. For people without reliable home internet, libraries provide essential services such as printing resumes, attending virtual interviews, or completing online schoolwork.

One key transformation has been the integration of digital literacy programs. Rather than focusing solely on traditional reading, libraries have expanded to include workshops on online safety, coding for children, and even technology troubleshooting for senior citizens. These programs aim to ensure that all age groups can navigate the modern digital environment confidently.

The architecture of libraries has also changed. Older models emphasized silence and study, while today’s designs often include open areas for group discussion, audio-visual zones, and even cafes. Architects now view libraries as dynamic, multifunctional public spaces rather than quiet repositories of books.

Still, funding remains a concern. While some cities have invested heavily in modernizing their library systems, others have cut budgets due to shifting priorities or economic constraints. The disparity is particularly visible in rural versus urban areas. While metropolitan libraries may offer state-of-the-art amenities, rural branches sometimes struggle to maintain even basic services.

Another challenge is the perception of redundancy. With the proliferation of smartphones and affordable data plans, some argue that public libraries are no longer essential. However, advocates counter this by emphasizing libraries’ role in promoting equal opportunity, supporting early childhood education, and encouraging lifelong learning.

In fact, during crises such as the COVID-19 pandemic, libraries played an unexpected role. Many offered curbside pickup services, virtual story times for children, and expanded access to e-book lending platforms. Some even partnered with local food banks to support vulnerable populations.

Libraries are also increasingly curating digital content and forming partnerships with educational institutions. Collaborations with universities, for example, have led to open-access research portals and community lecture series. In some countries, libraries have become central to national digital inclusion strategies.

The future of public libraries may lie in their flexibility. As community needs evolve, so too will the services libraries offer — whether through augmented reality archives, maker spaces for inventors, or language learning cafés. What remains unchanged is the core mission: to offer free, inclusive access to knowledge.

📄 Passage:

Sleep is a fundamental biological process that affects virtually every system in the human body. While most people understand the importance of getting a good night’s sleep, few realize the complexity of the brain activity involved in this seemingly passive state. The sleep cycle consists of multiple stages, each playing a distinct physiological and cognitive role.

The sleep cycle is broadly divided into two categories: REM (Rapid Eye Movement) sleep and non-REM sleep. Non-REM sleep has three stages, ranging from light sleep to deep, slow-wave sleep. These stages are responsible for physical restoration—muscle repair, immune function enhancement, and energy replenishment. REM sleep, in contrast, is associated with vivid dreams and plays a crucial role in memory consolidation and emotional processing.

A typical adult undergoes four to six sleep cycles per night, each lasting approximately 90 minutes. Early in the night, the body spends more time in deep non-REM sleep, whereas REM sleep dominates the later cycles, particularly in the early morning. Any disruption to this cycle—due to stress, irregular schedules, or medical conditions—can impair cognitive performance and emotional regulation.

Scientific interest in sleep has grown due to its connection to numerous health conditions. Chronic sleep deprivation has been linked to an increased risk of cardiovascular disease, diabetes, obesity, and mental health disorders such as depression and anxiety. Additionally, recent studies have shown that poor sleep can accelerate neurodegenerative diseases by interfering with the brain’s glymphatic system, which clears waste products during sleep.

One fascinating area of research involves circadian rhythms—the internal biological clock that governs the sleep-wake cycle. These rhythms are influenced by external factors such as light exposure and meal timing, but they are also genetically regulated. When circadian rhythms are misaligned, as seen in shift workers or individuals with jet lag, the result is often sleep disorders and metabolic disturbances.

Another key player in the regulation of sleep is melatonin, a hormone secreted by the pineal gland in response to darkness. Melatonin levels rise in the evening, promoting sleep, and fall in the morning as light stimulates wakefulness. However, excessive exposure to artificial light—especially blue light from screens—can inhibit melatonin production, delaying sleep onset and reducing overall sleep quality.

Modern life presents a paradox: while technological advancements have made our lives more convenient, they have also introduced new barriers to healthy sleep. Irregular work hours, nighttime screen use, and overstimulation from social media have contributed to what sleep researchers call a “sleep debt crisis.” In response, sleep hygiene practices—such as maintaining a consistent sleep schedule, limiting caffeine intake, and creating a calming bedtime routine—are now widely recommended.

Sleep research continues to evolve, with growing interest in individual differences in sleep need and sleep architecture. Some people naturally require more or less sleep, and the proportion of REM versus non-REM sleep may vary due to age, lifestyle, and genetics. Personalized sleep medicine, which tailors interventions to the individual’s sleep profile, may represent the future of insomnia treatment and general well-being optimization.

What is clear is that sleep is not merely a luxury but a necessity. As our understanding deepens, the evidence continues to show that protecting and prioritizing sleep is critical not just for energy and mood—but for long-term brain and body health.

The Secret Lives of Urban Trees
In the midst of concrete jungles, urban trees stand as overlooked sentinels. Far more than decorative green fixtures, these living organisms play vital roles in regulating air quality, managing stormwater, and supporting human well-being. Yet, only recently have researchers begun to uncover the dynamic lives of trees thriving in cities.

Urban forestry is now a multidisciplinary field that blends ecology, climatology, health sciences, and engineering. Scientists have discovered that city trees differ significantly from their forest counterparts—not just in appearance but also in function and physiology. Their root systems often grow shallow due to compacted soil and underground infrastructure. Additionally, heat islands—urban areas with elevated temperatures—cause trees to grow faster but often age prematurely.

A fascinating aspect of urban trees is their role in carbon sequestration. While forests are traditionally associated with storing carbon dioxide, urban trees can be more efficient per tree due to their rapid growth and longer growing seasons. However, this efficiency is sometimes offset by increased mortality rates due to stress from pollution, limited space, and mechanical damage from vehicles or human activity.

One breakthrough study from the University of Toronto used acoustic sensors to monitor the internal “clicks” and “pops” of city trees. These sounds indicate internal water stress or embolism—air bubbles blocking water flow in xylem vessels. Researchers concluded that trees in highly trafficked areas experience more stress, even when visually healthy.

Beyond environmental impact, urban trees also influence human psychology. Exposure to green spaces has been linked to reduced anxiety, improved mood, and lower cortisol levels. One long-term study in Chicago found that individuals living on tree-lined streets reported higher satisfaction with life, even after controlling for income and employment status.

Urban planners are now using this data to promote “green infrastructure”—a strategy that includes not only planting more trees but planting the right trees. Native species tend to adapt better and require less maintenance. Moreover, diversity is critical. Monoculture planting, where a single tree species dominates an area, has historically made cities vulnerable to pests and diseases. The case of the American elm, devastated by Dutch elm disease in the mid-20th century, remains a cautionary tale.

Some cities are experimenting with "smart trees"—urban trees embedded with sensors to monitor soil moisture, air quality, and temperature. These high-tech additions allow city officials to remotely manage tree health and even predict when a tree might fall.

Despite these innovations, challenges persist. In lower-income neighborhoods, tree canopy coverage tends to be significantly lower than in wealthier districts, creating what some researchers call a “shade gap.” This disparity contributes to higher summer temperatures, lower air quality, and reduced access to mental health benefits in marginalized communities.

Ultimately, the value of urban trees extends far beyond aesthetics. As cities prepare for rising temperatures and denser populations, trees must be viewed as integral components of urban infrastructure—living, evolving systems that demand both attention and respect.

The Evolution of Crowdsourcing

The term crowdsourcing was coined in 2006 by journalist Jeff Howe to describe a new phenomenon: using large groups of people, typically via the internet, to perform tasks once done by professionals. But the idea of distributing work among a broad base is far from new. In fact, examples of crowdsourcing can be traced back centuries.

One of the earliest recorded cases comes from 1714, when the British government offered a reward—known as the Longitude Prize—for anyone who could devise a reliable method for determining a ship’s longitude at sea. This public challenge attracted inventors and scientists across the country, and ultimately led to the development of the marine chronometer.

In modern times, technology has dramatically increased the scope, speed, and sophistication of crowdsourcing. Wikipedia is perhaps the most recognizable example—a global encyclopedia written and edited by volunteers. Despite skepticism over the quality of publicly edited content, Wikipedia is often found to be as reliable as traditional encyclopedias, thanks to its transparent editing history and rapid updates.

Another major application of crowdsourcing is in scientific research. Projects like Galaxy Zoo ask internet users to classify images of galaxies—a task that would take decades for a small research team but can be accomplished in weeks through collective effort. This method of engaging the public in academic research is referred to as citizen science.

In the business world, crowdsourcing is used for innovation, problem-solving, and product development. Platforms such as Innocentive allow companies to post complex challenges to a global pool of experts and hobbyists alike. The winning solution often comes from an unexpected source—sometimes a student or retiree with unique insight.

Design and branding have also been transformed by crowdsourcing. Websites like 99designs allow clients to receive design submissions from hundreds of freelancers, selecting their favorite and awarding the winner a prize. While this democratizes opportunities, it also raises concerns about exploitation and devaluation of creative labor.

Crowdsourcing has also entered public policy. Governments have experimented with sourcing ideas from citizens on issues ranging from urban planning to constitutional reform. Iceland, for example, used crowdsourcing techniques in 2011 to draft a new constitution by collecting public feedback via social media.

However, not all aspects of crowdsourcing are positive. Critics argue that the quality of contributions is inconsistent and that relying on unpaid labor can create ethical dilemmas. Moreover, the anonymity of the internet may foster irresponsible or harmful behavior if not carefully moderated.

Despite these concerns, the future of crowdsourcing looks bright. With the rise of artificial intelligence, many anticipate hybrid models where humans and machines collaborate—humans bringing creativity and judgment, while AI handles data processing and pattern recognition.

Ultimately, crowdsourcing represents a shift in how value is created. It challenges the traditional boundaries of expertise, authority, and ownership, encouraging new forms of collaboration in the digital age.

The Science of Geothermal Energy

Paragraph A
Geothermal energy originates from the heat stored beneath the Earth’s surface. This heat stems from both the planet’s original formation and the radioactive decay of elements such as uranium, thorium, and potassium within the Earth’s crust and mantle. While temperatures at the Earth’s core can reach over 6,000°C, usable geothermal energy is typically extracted from depths of 1 to 10 kilometers, where temperatures range between 150°C and 400°C. Unlike fossil fuels, geothermal energy is considered renewable, as heat from the Earth is virtually inexhaustible on a human timescale.

Paragraph B
The methods of extracting geothermal energy vary depending on geological conditions. In areas with naturally occurring geothermal reservoirs—such as Iceland, the Philippines, and parts of the United States—high-temperature fluids are tapped directly to generate electricity. These reservoirs are typically found near tectonic plate boundaries where volcanic activity is high. In other regions, engineers use enhanced geothermal systems (EGS), which involve injecting water into hot dry rock to produce steam. This process requires advanced drilling and stimulation techniques and is still being optimized for commercial use.

Paragraph C
Geothermal plants fall into three main categories: dry steam, flash steam, and binary cycle. Dry steam plants are the oldest and use steam extracted directly from underground reservoirs. Flash steam plants take high-pressure hot water and allow it to vaporize or "flash" into steam when pressure is reduced. Binary cycle plants, on the other hand, pass geothermal fluid through a secondary fluid with a lower boiling point, such as isobutane, which vaporizes and drives the turbine. Binary systems are well suited for lower-temperature resources and are considered more environmentally friendly due to closed-loop designs.

Paragraph D
The environmental impact of geothermal energy is comparatively low. Unlike coal or gas plants, geothermal facilities emit very little greenhouse gases. However, some environmental challenges remain. These include the release of trace gases such as hydrogen sulfide, land subsidence, and potential contamination of groundwater if wells are not properly sealed. Additionally, the siting of geothermal plants can conflict with local ecosystems or indigenous land rights, requiring careful environmental assessment and community consultation.

Paragraph E
Despite its advantages, geothermal energy faces economic and technical barriers. The high upfront cost of drilling and exploration can deter investment, especially when geological risks are uncertain. Operating costs are generally low once a plant is running, but the initial capital can be up to 60% of total project cost. Furthermore, geothermal resources are geographically limited, and effective utilization depends on local heat gradients, permeability, and water availability. Advances in drilling technology, subsurface imaging, and EGS are critical to expanding geothermal potential globally.

Paragraph F
In the context of global decarbonization, geothermal energy plays a vital role in the transition to a cleaner energy system. Unlike solar or wind, it provides a consistent and reliable base load supply. Countries such as Kenya, New Zealand, and Indonesia have significantly increased their geothermal capacity, integrating it into national energy strategies. Moreover, direct use of geothermal heat—such as for district heating, greenhouses, or industrial applications—offers energy-efficient alternatives in regions with suitable resources.
