Every day, email providers quietly block billions of ① unwanted messages before they ever reach a user's inbox, a task that would be impossible without an AI filtering system running constantly in the background. The filter ② examines each incoming message for suspicious patterns, including certain keywords, unusual sender addresses, and formatting tricks that scammers commonly rely on to slip past detection. What makes the system effective is that it ③ stops learning after launch, since whenever a user marks a message as spam or rescues a message mistakenly filtered out, that action becomes new training data, sharpening the filter's future decisions. This creates a constant back-and-forth, since spammers study which messages get blocked and then ④ adjust their wording to slip through again. As a result, spam filtering is less like a fixed wall and more like an ⑤ ongoing contest, with each side continuously adapting to outsmart the other.

Recovering from a serious sports injury involves far more than simply waiting for torn tissue to heal; it requires a carefully structured program that ① gradually reintroduces stress to the affected area. Immediately after an injury, rest and gentle range-of-motion exercises help prevent stiffness without ② disturbing the healing tissue. As pain subsides, therapists introduce light resistance training, slowly ③ weakening strength in muscles that have weakened from disuse. Progressing too quickly at this stage is a common mistake, since tissue that appears healed on the surface may still be ④ structurally fragile beneath it. Skipping the final stage, even when an athlete feels fully recovered, dramatically ⑤ increases the risk of re-injury.

Having grown up with smartphones and social media, they research products ①extensively online before making even small purchases. Unlike older generations, who often valued brand loyalty above all else, many members of Generation Z ②prioritize a company's values, switching brands easily if one no longer matches their beliefs. They also tend to ③favor secondhand and resale platforms, viewing sustainability as an important factor. Peer recommendations shared through short videos frequently carry ④less weight than traditional celebrity endorsements, since viewers see these creators as relatable rather than distant figures. Businesses that fail to adapt to these preferences risk losing an entire generation of potential customers, so many companies now invest in ⑤authentic engagement.

For decades, athletes were taught to stretch a muscle and hold the position before any competition, believing that this practice alone would prevent injury. Recent research, however, has complicated that assumption considerably, since static stretching, in which a muscle is held at its longest length for an extended period, can actually _______________. Dynamic stretching, which involves controlled, repeated movement through a joint's full range of motion, appears to prepare muscles for activity without this problem.

Secondhand trading platforms, once considered a niche market for used goods, have grown into a mainstream part of consumer culture. Rising prices for new products, combined with growing awareness of environmental waste, have encouraged many shoppers to consider used items before purchasing something brand new. These platforms allow individuals to sell clothing, electronics, and furniture directly to other consumers, cutting out traditional retail markups entirely. However, buying secondhand carries certain risks, since items cannot always be inspected closely before purchase, and some sellers misrepresent the condition of their products. To address this problem, many platforms now offer buyer protection programs and detailed rating systems for sellers. As trust in these systems continues to grow, ___________.

Even a modest level of dehydration, as little as two percent of body weight lost through sweat, can measurably reduce an athlete's endurance and cognitive sharpness during competition. (A) Dehydration also impairs the body's ability to regulate its own temperature, since sweating is the primary mechanism for releasing excess heat during intense exercise. (B) As fluid levels drop, blood volume decreases, forcing the heart to work harder to deliver the same amount of oxygen to working muscles, which accelerates fatigue. (C) Athletes competing in hot, humid conditions therefore face a particularly difficult balance, since sweating heavily to stay cool simultaneously depletes the very fluids needed to sustain performance.

Many people who try digital detox for the first time report feeling anxious within the first few hours. (A) This initial discomfort, sometimes called withdrawal anxiety, tends to fade after a day or two as the mind adjusts to reduced stimulation. (B) Once that adjustment period passes, most participants describe a noticeable sense of calm that they had not expected. (C) This unexpected calm often motivates people to repeat the practice regularly instead of treating it as a one-time experiment.

Mira grew up in a small village where fishing and farming had sustained her family for generations. (A) International organizations, however, still struggle to agree on how to protect people like her, since climate migrants are not officially recognized as refugees under current law. (B) Mira missed her old house terribly, yet she slowly began to build a new life in the crowded city, learning to adapt just as her ancestors once had. (C) When the sea finally swallowed the rice paddies that had fed her village for generations, her parents decided that staying was no longer possible. Together with many neighbors, they packed what little they could carry and moved inland, becoming what experts now call climate migrants, people forced to abandon their homes because of rising seas, droughts, or other disasters. This term, rarely used a decade ago, has become increasingly common as extreme weather displaces communities worldwide.

Imagine two factories making the same product: one in a country with strict carbon rules, and one in a country with almost none. (A) However, critics claim it unfairly burdens developing countries, which often lack money to modernize factories quickly. For example, a small exporter in a poorer nation might struggle to pay the added charge, though it contributes little to global emissions. Still, if wealthier nations pair the policy with technical support, it could become a genuinely fair tool for cutting emissions worldwide. (B) Supporters argue that the system protects domestic industries and pushes foreign manufacturers toward cleaner methods. (C) The factory facing stricter rules often spends more, which can make its goods pricier than those made elsewhere. To fix this imbalance, some governments have introduced the carbon border adjustment mechanism, a policy charging imported goods a fee based on how much carbon was released while producing them.

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.
