Almon Strowger, an American engineer, constructed the first automatic telephone switching system, which had a horizontal, bladelike contact arm, in 1891. The first commercial switchboard based on his invention opened in La Porte, Indiana, a year later and was an instant success with business users. To access the system, the caller pressed button to reach the desired number and turned the handle to activate the telephone ringer. During the same year, Strowger’s step-by-step call advancement technology was implemented in the long-distance service between New York and Chicago when it proved to have the capacity of carrying signals through cable-joint extensions.

The first actual dial telephone, patented by Lee De Forest in 1907, was installed in Milwaukee in 1906. In 1912, their sound transmittal apparatus adapted an electronic tube to function as an amplifier. Transatlantic radio-telephone service linked New York and London in 1927. However, the long distances coaxial cable, which was hailed as unprecedented, came on the scene in 1936 connecting New York and Philadelphia. The Bell Laboratories research facility came up with the transistor to replace the cumbersome vacuum tube, thus diminishing the size of the electronic switch system to about 10 percent of that of the original. Crossbar switching, installed in terminals in 1938, operated on the principle of an electromagnetic force, which rotated horizontal and vertical bars within a rectangular frame and brought contacts together in a split second. A technological breakthrough in the form of undersea cables between the United States and Hawaii was implemented almost twenty years later. An extension was connected to Japan in 1964.

After more than fifteen years of negotiations and public campaigning, the Global Ocean Treaty entered into force in early 2026. For the first time, areas of the ocean beyond national jurisdiction are subject to an international framework intended to facilitate large-scale marine conservation. Environmental organisations view the agreement as a decisive shift, addressing decades of fragmented governance and limited oversight in the High Seas, where economic interests have often taken priority over ecological concerns.
Less than one percent of these waters is currently fully or highly protected. This regulatory gap has enabled industrial fishing and potential deep-sea mining activities to proceed with relatively few constraints. [I] The Treaty introduces a procedure allowing governments to designate marine protected areas in international waters. If applied ambitiously, such measures could safeguard over one-third of the global ocean, forming an unprecedented network of protected ecosystems.
The agreement's relevance extends beyond biodiversity. Oceans absorb a significant share of global carbon emissions and help stabilise the planet's climate systems, acting as a buffer against more extreme warming trends. Nearly half of Earth's biodiversity exists beneath the waves, and billions depend on marine ecosystems for food security and economic stability. Protecting the High Seas is therefore closely linked to both environmental balance and human welfare.
[II] However, legal recognition alone does not ensure ecological recovery. Implementation will rely on political resolve, credible scientific assessment and cooperation among states. Proposals for protected zones must be supported by evidence-based evaluations and developed in consultation with affected communities. In the absence of effective monitoring and enforcement mechanisms, conservation commitments may lack practical impact.
Governments have pledged to protect 30 percent of the world's oceans by 2030 – a target commonly known as "30x30." [III] Achieving this ambition requires identifying ecologically critical regions and limiting extractive activities accordingly. The first Conference of the Parties (COP) will influence how obligations are interpreted and applied in practice.
[IV] The Treaty signals progress in international environmental diplomacy. Whether it ultimately reshapes ocean governance will depend on the extent to which states convert formal commitments into sustained action.

Why we crave dessert even when we are full

Even after eating a large meal, most people can still find room for sweets. Now, research in mice shows that the neurons behind feeling full also trigger sugar cravings. In other words, there seems to be a neurological basis for our love of dessert. (I)

Previous studies have shown that naturally occurring opioids in the brain play a crucial role in sugar cravings. The main producers of these opioids are neurons located in a brain region that regulates appetite, metabolism and hormones. Known as pro-opiomelanocortin (POMC) neurons, they also control feelings of satiety after eating.

To understand whether these cells have a role in sugar cravings, Henning Fenselau at the Max Planck Institute for Metabolism Research in Germany and his colleagues traced the opioid signals that POMC cells send in the brain. They did so by bathing brain slices from three mice in a fluorescent solution that binds to receptors of these opioids. (II) The brain region with the highest density of these receptors was the paraventricular nucleus of the thalamus (PVT), known to regulate feeding. That suggested sugar cravings were related to communication between these two brain regions. This observation provided a clearer map of the neural circuitry involved, allowing the researchers to focus on specific pathways rather than general brain activity. It also helped establish a functional link between receptor density and behavioural outcomes related to food intake, thereby strengthening the overall reliability of their experimental approach. (III)

Subsequently, the researchers monitored the activity of neurons in these regions as mice ate their usual food. When the animals seemed to be full, the team gave them a dessert of sugary chow. (IV) On average, neuronal activity between the brain regions roughly quadrupled while mice ate dessert compared with their regular meal. The spike began prior to eating the sweets, suggesting the pathway dictates sugar cravings. When the team inhibited signals from POMC neurons to the PVT, the mice consumed 40 percent less dessert. “The cell types, which are extremely well-known for driving satiety, also release signals that cause the appetite for sugar, and they do so particularly in the state of satiety,” says Fenselau. “This would explain why animals – humans – over-consume sugar when they’re actually full.” The pathway may have evolved because sugar is more easily turned into energy than other sources like fats or proteins.

Read the passage and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions 18 to 27.
The alarming surge in human trafficking from Vietnam to Cambodia has emerged as one of Southeast Asia's most pressing humanitarian crises, with thousands of victims ensnared in sophisticated criminal networks operating cyber-scam compounds. [I] These operations, disguised as legitimate employment opportunities promising lucrative salaries in customer service or technology sectors, systematically exploit economic vulnerabilities prevalent throughout Vietnam's rural provinces. Victims, predominantly young adults seeking upward mobility, discover upon arrival that they've been sold into forced labor, compelled to execute online fraud schemes targeting international victims while enduring brutal conditions and severe physical punishment for resistance or underperformance.
[II] The trafficking pipeline operates with disturbing efficiency through coordinated recruitment networks spanning Vietnam's poorest regions. Agents offering overseas employment circulate through villages, presenting fabricated contracts guaranteeing monthly salaries exceeding $1,000—figures representing transformative income for families subsisting on agricultural wages. Sophisticated deception extends beyond initial recruitment; victims receive detailed orientation materials, fraudulent company documentation, and testimonials from supposed employees. Only upon crossing borders, frequently through irregular channels avoiding official checkpoints, do victims comprehend the authentic nature of their situation when passports are confiscated and escape becomes impossible.
The scam compounds themselves, concentrated near Cambodia's borders with Thailand and Vietnam, function as modern slavery operations concealed behind legitimate business facades. [III] Victims endure eighteen-hour workdays executing romance scams, cryptocurrency fraud, and investment schemes targeting predominantly Western victims through meticulously crafted online personas. Failure to meet daily quotas—often requiring extraction of thousands of dollars from marks—results in physical beatings, food deprivation, electric shock torture, and threats against families remaining in Vietnam. Survivors' testimonies document horrifying conditions including sexual assault, forced drug consumption to maintain productivity, and witnessed murders of those attempting escape or becoming commercially unviable through injury or psychological breakdown.
Vietnamese and Cambodian authorities face extraordinary challenges combating these transnational criminal enterprises. [IV] Despite bilateral cooperation agreements and increased border surveillance, traffickers continuously adapt methodologies, exploiting corruption within law enforcement agencies and capitalizing on jurisdictional complexities inherent in cross-border crimes. Diplomatic tensions periodically surface when rescue operations encounter resistance from Cambodian officials allegedly complicit with trafficking networks or protective of foreign investment relationships with companies operating these compounds. International organizations estimate that tens of thousands remain trapped, with rescue efforts recovering merely a fraction while trafficking continues unabated, sustained by poverty's endless supply of vulnerable recruits and cyber-scam industries' exponentially growing profitability.

Many extinct species – from passenger pigeons to woolly mammoths – may now be reclassified as “bodily, but not genetically, extinct”, since their DNA can still be recovered from fossil specimens up to 200,000 years old. Developments in genetic technology may one day help bring such animals back to life. Only species whose DNA is too old to recover, such as dinosaurs, should be regarded as truly extinct.



The attempt to bring vanished creatures back to life will be expensive, technically difficult, and time-consuming, with no guarantee of success, so what makes it worthwhile? That something as final as extinction might be reversed, so that mammoths and passenger pigeons could be seen alive again, evokes the awe and wonder that drive all conservation at its deepest level.

Furthermore, the same logic underlying initiatives to protect endangered species applies to de-extinction plans: to restore and preserve biodiversity, advance scientific knowledge, and undo previous destruction. In this sense, resurrected species could become beacons of hope. While close examination of extinct species’ genomes can speak volumes about what made them vulnerable in the first place, living specimens would reveal even more. De-extinction techniques would also be directly applicable to critically endangered species, helping restore their genetic diversity. Lastly, as some extinct species once played vital roles in their ecosystems, bringing them back could also revive ecological richness and inspire wider conservation.

If de-extinction succeeds, today’s young people will have a chance to experience the return of some remarkable creatures in their lifetime – an experience that may define their generation’s attitude to the natural world and conservation. Given the number of species that have died out over the last 10,000 years due to manmade destruction, some resurrection and a measure of redemption are in order.

As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning to night, it is hard to slow down. But relaxation is essential fora healthy mind and body.
Stress is a natural part of every life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.
The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress in whatever form, we react both chemically and physically. In fact we make choice between "fight" or "flight", and in more primitive days the choice made the difference between life or death. The crises we meet today are not likely to be so extreme, but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. Since we cannot remove stress from our lives (and it would be unwise to do so even if we could), we need to find ways to deal with it.

In 2007, at a heavily hyped press event in San Francisco. Apple co-founder Steve Jobs stood on stage and unveiled a revolutionary product that not only broke the mold but also set an entirely new paradigm for computer-based phones. The look, interface and core functionality of nearly every smartphone to come along since is, in some form or another, derived from the original iPhone's innovative touchscreen-centric design.

Among some of the ground-breaking features was an expansive and responsive display from which to check email, stream video, play audio, and browse the internet with a mobile browser that loaded full websites, much like what is experienced on personal computers. Apple's unique iOS operating system allowed for a wide range of intuitive gesture-based commands and eventually, a rapidly growing warehouse of downloadable third-party applications.

Most importantly, the iPhone reoriented people's relationship with smartphones. Up to, then, they were generally geared toward businesspeople and enthusiasts who saw them as an invaluable tool for staying organized, corresponding over email, and boosting their productivity. Apple's version took it to a whole other level as a full-blown multimedia powerhouse, enabling users to play games, watch movies, chat, share content, and stay connected to all the possibilities that we are all still constantly rediscovering.

A common phenomenon in arid regions of the world is the whirling vortex called the “dust devil.” Although they resemble tornadoes, dust devils are generally much smaller and less intense than their more destructive cousins. Most dust devils are only a few meters in diameter and reach heights no greater than about 100 meters. Further, these whirlwinds are usually short-lived microscale phenomena: most form and die out within minutes. Unlike tornadoes, which are associated with clouds, dust devils form on days when clear skies prevail. Further, these whirlwinds form from the ground upward, exactly the opposite of tornadoes. Because surface heating is critical to their formation, dust devils occur most frequently in the afternoon, when surface temperatures are highest.

Dust devils form when the hot surface of the earth warms the air above it. When the air near the surface is considerably warmer than the air a few tens of meters overhead, the layer of air near Earth’s surface becomes unstable. In this situation, warm surface air begins to rise, causing air near the ground to be drawn into the developing whirlwind. A light wind will start this rising air to rotate, and once the rotation has begun, it becomes faster due to the same physical principle that causes ice-skaters to spin faster as they pull their arms closer to their body. As the inwardly spiraling air rises, it carries sand, dust, and other loose debris tens of meters into the air. It is this material that makes a dust devil visible. Occasionally, dust devils form above ground covered with vegetation. Under these conditions, the vortices may go undetected unless they interact with objects at the surface.

Most dust devils are small and short-lived; consequently, they are not generally destructive. Occasionally, however, these whirlwinds grow to be 100 meters or more in diameter and over a kilometer high. Larger and more vigorous dust devils have a longer lifetime than smaller ones. One large dust devil, with a height of about 750 meters, lasted for seven hours as it traveled 64 kilometers in western Utah. With winds that whirl at speeds that may reach 100 kilometers per hour, such large dust devils can do considerable damage.

Many people see large urban cities as a wonder of human imagination and creativity. They represent how far the human population has come in terms of community development. Many positive things come from urbanization, but there are also negatives. This article will discuss and present data on the implications of urbanization on the physical health of humans living in these large urban areas.
As it would be expected, developing countries tend to see more negative physical health effects than modern countries in regard to urbanization. One example of a developing country experiencing these problems is China. China is a country that in the past 30–40 years went from being an agrarian based society to a significant industrialized country. This industrialization has in effect caused the need for more centralized cities, centralized meaning having lots of jobs and living spaces within a close proximity. This is what is known as urbanization. In most recent decades, since China's change to being more of an industrial based economy, the country has experienced record high numbers of people migrating within its borders. In effect, the number of cities with over 500,000 people has more than doubled. These migrations are typically of people from rural areas of China moving to the new urban areas. Due to this large influx in the urban population, there are many possibilities for health challenges among these people.
One very common and fairly obvious negative aspect of highly congested urban areas is air pollution. Air pollution is defined as any harmful substance being suspended in the air. This could include particulate matter, most commonly attributed to industrial plants and refineries waste, or chemicals like CO2 or Methane (which are also products of plants and refineries as well as cars and other modes of transportation). Due to a vast number of people in these urbanized cities, the air pollution is known to be very extreme. These conditions can lead to many different health problems such as: Asthma, cardiovascular problems or disease, and different types of cancer (most commonly lung cancer). When exposed to these conditions for a prolonged period of time, one can experience even more detrimental health effects like: the acceleration of aging, loss of lung capacity and health, being more susceptible to respiratory diseases, and a shortened life span.
Another way that urbanization affects the populations’ health is people’s change in diet. For instance, urban cities tend to have lots of accessible, quick, and easy to get food. This food is also more than likely not as high quality as well as contains a large amount of sodium and sugar. Because this food is so accessible, people tend to eat it more. This increase in consumption of low quality food can then lead to diabetes, hypertension, heart disease, obesity, or many other health conditions.

As technology rapidly advances and global challenges evolve, the landscape of future careers is undergoing significant transformation. Today’s students must prepare for jobs that may not yet exist, requiring a blend of adaptability, creativity, and continuous learning. The traditional notion of a linear career path is becoming obsolete, replaced by the concept of a career portfolio where individuals may pursue multiple professions throughout their lives.

Emerging fields such as artificial intelligence, renewable energy, and biotechnology are expected to drive job creation in the coming decades. These sectors demand a strong foundation in STEM (Science, Technology, Engineering, and Mathematics) disciplines, coupled with critical thinking and problem-solving skills. However, the importance of soft skills cannot be overstated. Emotional intelligence, communication, and cultural competence will be crucial in an increasingly interconnected global workforce.

The gig economy and remote work are reshaping traditional employment models. Many future professionals may find themselves working as independent contractors or freelancers, managing multiple projects simultaneously. This shift necessitates entrepreneurial skills, self-motivation, and the ability to navigate diverse work environments.

Lifelong learning will be paramount in staying relevant in the job market. As automation and AI continue to evolve, routine tasks are likely to be automated, emphasizing the need for uniquely human skills such as creativity, empathy, and complex problem-solving. Professionals must be prepared to upskill and reskill throughout their careers to adapt to changing industry demands.

While the future job market may seem uncertain, it also presents unprecedented opportunities for innovation and personal growth. By cultivating a growth mindset, embracing technological literacy, and developing a diverse skill set, today's students can position themselves for success in the dynamic career landscape of tomorrow.

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.

The Great Debate over GM Foods

One of the hottest topic in agriculture today is genetically modified (GM) foods. GM foods have been on the market since 1994, when a company called Calgene started selling GM tomatoes. Since then, other GM foods including papaya, corn, and plums to name a few have been developed.

The main benefit of GM foods is that they can be a more economical solution than non GM foods. Scientists found a way to modify many plants to make them more resistant to weeds, diseases, and pests. This allows the plants to grow in tougher climates and conditions, which should lead to lower food prices and increase the overall food supply.

However, many consumers still have their doubts about GM foods. For one, they feel that by eating GM foods people are messing with nature. Until now, humans have survived on food that was produced without any interference from science. Even though many lab studies show that GM foods are safe in the short term, opponents feel that not enough long-term testing has been done yet.

Another major issue in the GM foods debate is its labelling. Current US laws do not require producers to label their foods as GM. This has upset many consumers who feel they have the right to clearly know how the food they are buying is produced. On the other hand, producers are afraid to label their foods as GM because they feel it will result in less product sales, as people may assume that there is something wrong with GM foods.

This controversy is not just on the level of consumers and producers. The issue of non GM foods has also become a block to a major free trade agreement between the US and Europe. GM foods are banned throughout most of Europe, while they are quite common throughout the US. Since many American GM food producers would like to sell their foods overseas in Europe, the US is requesting that European nations eliminate laws banning GM foods. However, many European nations are not fully convinced that these products are safe.

3D printers have been widely used in educational settings from K–12 schools to universities as tools that support experiential learning and innovation. They are placed in various locations and environmental settings on campus, such as classrooms, maker centers, laboratories, and offices, alongside other office equipment such as photocopy machines, and are used for teaching, research, design, and prototyping in engineering, architecture, and other fields. In particular, university maker centers often house diverse types and multiple 3D printers within a single space, where these devices may operate continuously for extended periods. This intensive and frequent use increases the likelihood of prolonged exposure to emissions for students and staff working nearby.
Chemical Insights Research Institute (CIRI) has conducted a multi-year research initiative on 3D printer emissions and has found that 3D printing produces ultrafine particles (UFPs, smaller than 100 nm) as well as volatile organic compounds (VOCs). Due to their extremely small size, UFPs can remain suspended in the air for long durations and are easily inhaled. Once inhaled, these particles may penetrate deep into the lungs and even enter the bloodstream, which has been linked to respiratory and cardiovascular diseases.
In addition, some VOCs released during 3D printing processes have been associated with both acute and chronic adverse health effects, including eye and throat irritation, respiratory illness, and, in some cases, cancer, depending on exposure duration and concentration levels. The use of 3D printers on campuses can therefore contribute to elevated levels of indoor air pollutants, raising particular concerns for vulnerable populations such as individuals with asthma or other pre-existing respiratory conditions.
As a result, the growing prevalence of 3D printers in educational environments has increased attention to indoor air quality management. In enclosed or poorly ventilated spaces, continuous printer operation may lead to the accumulation of airborne pollutants, thereby heightening potential health risks. Consequently, systematic monitoring of particle and VOC levels, together with effective ventilation and exposure mitigation strategies, is essential to ensure a safe learning and working environment.

In response, the concept of JOMO (Joy of Missing Out) has emerged, advocating for a radical reclamation of cognitive sovereignty. Unlike the outward-looking envy of FOMO, JOMO prioritizes the internal quality of experience over the external quantity of engagement. However, transitioning to JOMO is not a simple act of individual willpower; it requires a structural separation from the attention economy. It necessitates a fundamental shift in how we value "unproductive" time in a society that considers constant activity as social and professional worth.

We seem to be entering a boom era for greenwashing – the tactic of covering routine pollution in eco-friendly language. [I] Picture running a high-emitting corporation: meaningful decarbonisation would demand painful negotiations, huge capital outlays, and a full redesign of the business model. Hiring an expert agency to splash “carbon-neutral” or “net-zero” across products is far easier, buying time while emissions remain untouched. Consumers meet this sleight of hand everywhere. Airlines sell “carbon-neutral” flights, filling stations boast about “net-zero” fuel, and breakfast bacon is re-labelled as planet-safe. Advertising spin is old, yet today it is manipulated to conceal ongoing environmental damage. Social media influencers and glossy sustainability reports amplify these claims, broadcasting the narrative far beyond traditional marketing channels. The term greenwashing emerged in the 1980s, an era of oil spills and growing climate science, but the practice has exploded only recently. [II] Intensifying public anxiety over global heating and ecosystem collapse has placed companies under sharp scrutiny; many boards therefore choose eye-catching PR over the tougher route of restructuring supply chains, energy sources, and product lines. Regulators on both sides of the Atlantic are struggling to police false eco-claims, yet enforcement still lags behind corporate ingenuity. Investors, eager to protect short-term returns, frequently applaud these surface-level initiatives, reinforcing the cycle. [III] No sector illustrates the issue better than oil and gas. Having realised that denying climate science now backfires, the industry has swapped denial for “green” paint. Press releases trumpet potential renewable ventures while drilling plans expand unabated. Why does this matter? Greenwashing and climate denial share a core objective: to postpone the deep emission cuts claimed by scientists as urgent this decade. [IV] Whereas denial disputes the crisis, greenwashing misleads the public into believing problems are solved, thereby eroding consumer advocacy of genuine environmental actions and stalling regulatory reforms. In effect, it acts as a soothing lullaby, guiding society ever closer to ecological breakdown while fostering a false sense of progress. Exposing the facade – and insisting on verifiable, measurable carbon reductions – is essential if rhetoric is to give way to real action.
