Passage 1: The Rise of Urban Green Spaces (13 câu)

Cities around the world are increasingly recognizing the importance of green spaces for the health and well-being of their residents. Parks, gardens, tree-lined streets, and urban forests are no longer seen as mere aesthetic additions to the urban landscape but as essential infrastructure that supports physical health, mental well-being, and social cohesion.

Research has consistently shown that access to green spaces reduces stress, anxiety, and depression. A landmark study conducted in Denmark followed over 900,000 residents born between 1985 and 2003, finding that children who grew up with the least green space had up to 55% higher risk of developing mental health disorders. Similarly, a Japanese study on “forest bathing” — the practice of spending time in forested areas — demonstrated measurable reductions in cortisol levels and blood pressure after just 15 minutes of walking among trees.

The physical health benefits are equally compelling. Green spaces encourage physical activity; people living near parks are three times more likely to meet recommended exercise levels. Urban trees filter air pollution, with a single mature tree absorbing up to 22 kilograms of carbon dioxide per year. In hot climates, parks can reduce surrounding temperatures by 2-8°C through shade and evapotranspiration, mitigating the dangerous urban heat island effect.

The economic arguments for green spaces are also strengthening. Properties near well-maintained parks typically command 8-20% higher values. Cities with extensive green infrastructure spend less on healthcare and flood management. Singapore’s investment in becoming a “City in a Garden” has been credited with helping attract international businesses and talent, contributing to its economic competitiveness.

However, the distribution of green spaces often reflects existing social inequalities. Low-income neighborhoods and communities of color frequently have less access to quality parks and green areas. This environmental injustice has health consequences: residents of these areas experience higher rates of heat-related illness, respiratory problems, and mental health challenges. Addressing this green gap has become a priority for urban planners committed to creating more equitable cities.

Questions 1-5: True/False/Not Given

1. Green spaces are now considered essential urban infrastructure. → __________
2. The Danish study included more than one million participants. → __________
3. Forest bathing originated in China. → __________

   • B) 2-8°C
   • C) 5-10°C

8. Properties near parks are worth:

   • A) 5-10% more
   • B) 8-20% more
   • C) 15-30% more

9. Which city is mentioned as a “City in a Garden”?

Passage 2: The Science of Sleep (13 câu)

Sleep is one of the most fundamental biological processes, yet it remains one of the least understood. Humans spend approximately one-third of their lives sleeping, and disruptions to sleep patterns have been linked to a wide range of health problems, from obesity and diabetes to cardiovascular disease and weakened immune function.

Sleep occurs in cycles of approximately 90 minutes, alternating between non-rapid eye movement (NREM) and rapid eye movement (REM) stages. NREM sleep is divided into three stages: N1 (light sleep), N2 (moderate sleep, where the body begins to relax and body temperature drops), and N3 (deep sleep, critical for physical restoration). REM sleep, characterized by rapid eye movements and vivid dreaming, is believed to play a crucial role in memory consolidation and emotional processing.

The circadian rhythm, our internal 24-hour clock, is primarily regulated by light exposure. The suprachiasmatic nucleus (SCN) in the hypothalamus receives signals from the eyes about ambient light levels and coordinates the release of melatonin, the hormone that promotes sleepiness. Modern lifestyles have disrupted these natural patterns; the blue light emitted by screens suppresses melatonin production, while irregular work schedules and international travel create chronic misalignment between our internal clocks and external demands.

Sleep deprivation has profound cognitive consequences. After 17 hours without sleep, cognitive performance deteriorates to a level equivalent to a blood alcohol concentration of 0.05%. After 24 hours, this rises to 0.10% — above the legal driving limit in most countries. Chronic sleep deprivation impairs decision-making, creativity, and emotional regulation. Studies have shown that sleep-deprived individuals are significantly worse at recognizing facial expressions, potentially damaging social relationships.

Emerging research suggests that sleep serves a crucial housekeeping function for the brain. The glymphatic system, discovered in 2012, is a network of channels that becomes more active during sleep, flushing out toxic waste products including beta-amyloid, a protein associated with Alzheimer’s disease. This finding has led researchers to hypothesize that chronic sleep deprivation may contribute to neurodegenerative diseases, adding urgency to public health campaigns promoting adequate sleep.

Passage 3: The Future of Food — Lab-Grown Meat and Alternative Proteins (14 câu)

The global food system faces unprecedented challenges. With the world population projected to reach 9.7 billion by 2050, food production must increase by an estimated 70% to meet demand. Simultaneously, the environmental impact of conventional agriculture — particularly livestock farming — has come under intense scrutiny. Animal agriculture occupies 77% of global agricultural land while providing only 18% of calories and 37% of protein consumed worldwide. It accounts for 14.5% of global greenhouse gas emissions, uses 70% of freshwater withdrawals, and is a leading driver of deforestation and biodiversity loss.

Against this backdrop, alternative proteins have emerged as a potential solution. The market for plant-based meat alternatives has grown exponentially, reaching $7.9 billion globally in 2022. Companies have developed increasingly sophisticated products using combinations of soy, pea protein, wheat gluten, and other plant ingredients to replicate the taste, texture, and nutritional profile of conventional meat. However, consumer acceptance remains inconsistent; while initial curiosity drove strong sales, some companies have experienced declining revenues as repeat purchase rates have fallen below expectations.

Cultivated meat — grown from animal cells in bioreactors rather than raised on farms — represents perhaps the most transformative technology in food history. The process involves taking a small sample of cells from a living animal, placing them in a growth medium containing nutrients, and allowing them to multiply and differentiate into muscle and fat tissue. The first cultivated hamburger, produced by Dutch scientist Mark Post in 2013, cost $330,000. By 2023, production costs had fallen dramatically, though cultivated meat products remain significantly more expensive than their conventional counterparts.

The regulatory landscape for alternative proteins varies widely. Singapore became the first country to approve the sale of cultivated meat in December 2020, followed by the United States in 2023. The European Union has adopted a more cautious approach, requiring extensive safety assessments before granting market authorization. Some countries, including Italy and France, have moved to restrict or ban cultivated meat products, citing concerns about traditional food culture and the livelihoods of conventional farmers.

Nutritionally, alternative proteins present both opportunities and challenges. Plant-based products can be formulated to match or exceed the protein content of meat while containing less saturated fat and no cholesterol. However, they often contain higher levels of sodium and may lack certain micronutrients naturally present in animal products, such as vitamin B12, iron, and zinc. Cultivated meat, being biologically identical to conventional meat at the cellular level, should theoretically offer the same nutritional profile, though the effects of the production process on nutrient content are still being studied.

The environmental benefits of alternative proteins are substantial but nuanced. Life cycle analyses suggest that plant-based meat alternatives produce 30-90% fewer greenhouse gas emissions than conventional beef. Cultivated meat’s environmental footprint depends heavily on the energy source used to power bioreactors; when powered by renewable energy, emissions could be reduced by up to 92%, but fossil fuel-dependent production may offer only marginal improvements. Water usage and land requirements are dramatically lower for both alternatives, potentially freeing vast areas for ecosystem restoration or carbon sequestration.
