A printer that once produced only plastic prototypes can now ① deposit living cells layer by layer to build a structure that begins to resemble actual tissue. Bioprinting adapts the logic of conventional 3D printing, ② replacing plastic filament with a specialized ink made of living cells suspended in a gel that supports their survival while the shape sets. Printing a flat patch of skin or a simple blood vessel has already moved from laboratory curiosity to early clinical testing, since these tissues ③ is thin enough for nutrients to reach every cell by diffusion. Printing a solid organ such as a kidney remains a far greater challenge, because internal cells starve without their own blood supply, and no printer yet exists that can build a network of vessels fast enough ④ to keep them alive. Researchers are therefore focusing on hybrid strategies, printing a rough scaffold and then ⑤ allowing the tissue to mature and grow its own vasculature over time.

Devices that translate brain activity directly into digital commands have moved from laboratory experiments to real medical use, ① allowing paralyzed patients to control a robotic arm or type a message using thought alone. As the technology improves, some developers envision a future in which brain-computer interfaces extend beyond restoring lost function ② toward enhancing healthy minds, offering faster memory or expanded attention to anyone ③ willing to undergo the procedure. This prospect raises a philosophical question that medicine alone cannot answer: if a device can alter memory, mood, or decision-making, at what point does the assistance stop ④ being a tool and start reshaping the very identity of the person using it. Neuroethicists argue that mental privacy, the ability to keep one's own thoughts free from external access or manipulation, may need ⑤ recognizing as a fundamental right before this technology becomes widespread.

Biodegradable plastics have been promoted as a ①promising solution to plastic waste, since they are designed to decompose into natural substances rather than persist for centuries. Manufacturers derive these materials from renewable resources such as corn starch, blending them with additives that ②accelerate microbial breakdown once discarded. However, their environmental benefits are often exaggerated, largely because decomposition depends on specific conditions rarely found outside industrial composting facilities. For example, a bag labeled biodegradable may take years, not the weeks advertised, to break down in a landfill or ocean, where temperature and microbial activity remain ③high. In addition, when mixed with conventional plastics in recycling streams, they can ④contaminate the process, weakening the quality of materials produced afterward. Some engineers therefore compare biodegradable plastics to a bridge that leads nowhere unless paired with infrastructure that completes the journey. Ultimately, realizing their ⑤genuine potential requires not only technological refinement but also facilities capable of providing the precise conditions decomposition demands.

It is often assumed that memory operates independently of bodily context, yet research suggests that this assumption deserves reconsideration. When information is learned under a particular physiological or emotional condition, retrieval tends to ①improve if that same condition is reinstated at recall, a phenomenon researchers call state-dependent memory. Individuals who study while mildly anxious, for instance, often recall material more ②accurately when tested under similarly anxious conditions than when tested while calm, even though calmness is typically considered more conducive to concentration. This finding should prompt educators to reconsider the assumption that a single optimal testing environment exists for every learner, since matching internal states across encoding and retrieval provides retrieval cues that a ③mismatched state cannot supply. Critics might argue that such effects are minor and inconsistent, yet accumulated evidence across pharmacological and emotional studies is ④easy to dismiss. Policymakers designing assessments should therefore weigh not only content difficulty but also the physiological continuity between preparation and examination, since ignoring this dimension risks ⑤underestimating certain students' actual knowledge.

Many companies now advertise themselves as environmentally responsible, yet a growing number of these claims turn out to be misleading. This practice, known as greenwashing, _______________. A company might launch a recycled-packaging line while continuing to pollute rivers through its main factories, creating a false impression of genuine change. Such tactics deceive well-intentioned consumers who wish to shop responsibly but lack the tools to verify corporate claims. In contrast, truly sustainable businesses publish detailed, independently verified data about their emissions and supply chains, allowing outsiders to check their progress. Therefore, shoppers should look beyond vague labels like green or natural and instead search for recognized certifications, transparent reports, and measurable targets. Without such scrutiny, greenwashing will keep flourishing, undermining public trust and slowing the broader shift toward an economy that truly protects the planet.

Attention, all students! Our school will hold the New Year Goal Presentation Day on Friday, January 30th, in the main auditorium, where ___________. Each presentation should last no longer than two minutes and may include a poster or simple props to explain the goal clearly. Students who wish to participate must submit a short outline to their homeroom teacher by January 23rd.

Food poisoning cases increase sharply during the hot summer months because ___________. To protect yourself, wash your hands before preparing food, cook meat and eggs thoroughly, and keep perishable food in the refrigerator rather than leaving it out at room temperature.

Many people believe that a college major decides a person's entire career path. (A) A history major, for example, might later succeed as a marketer or a policy analyst. (B) However, many graduates actually end up working in fields unrelated to what they studied. (C) This shows that skills developed during study often matter more than the subject itself.

Military researchers have developed weapons systems capable of identifying and engaging targets without a human pressing the final button. (A) Human rights organizations counter that removing a person from the final decision strips away moral responsibility at the exact moment it matters most. (B) Advocates within defense agencies argue that autonomous systems can react faster than any human operator and may even reduce casualties. (C) Diplomatic negotiations toward an international treaty have repeatedly stalled, partly because military powers disagree on how to define autonomy precisely enough to regulate it.

주어진 문장: Yet this idea sounds strange to most people, who assume that close relationships would naturally provide better opportunities than distant ones. Sociologist Mark Granovetter introduced an idea that seems contradictory at first glance, known as the strength of weak ties. ( ① ) According to this theory, people who see each other only occasionally, called weak ties, often provide more valuable information than close friends or family members, who are considered strong ties. ( ② ) This happens because strong ties tend to share the same social circles and, therefore, already possess similar knowledge. ( ③ ) Weak ties, in contrast, move within different networks, which allows them to introduce ideas or opportunities that would otherwise remain unknown. ( ④ ) For example, a former classmate rarely contacted might mention a job opening unavailable through one's immediate circle. ( ⑤ ) Social media platforms have made maintaining such connections remarkably easier, letting users keep hundreds of loose acquaintances active without frequent face-to-face meetings.
