Every day, email providers quietly block billions of unwanted messages before they ever reach a user's inbox, a task that ①would be impossible without an AI filtering system running constantly in the background. The filter examines each incoming message for suspicious patterns, including certain keywords, unusual sender addresses, and formatting tricks that scammers commonly rely on ②to slip past detection. What makes the system effective is that it keeps ③learning after launch: whenever a user marks a message as spam or rescues a message mistakenly filtered out, that action ④become 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 adjust their wording to slip through again, ⑤resulting in an ongoing contest between each side.

Social media researchers use the term context collapse ①to describe what happens when a single online post ②reach audiences that would normally remain separate in offline life. In daily interactions, people naturally adjust their tone and content depending on whether they are ③speaking with family, close friends, or professional colleagues. However, a typical social media feed merges these distinct audiences into one undivided crowd, since a single post can simultaneously reach parents, employers, and casual acquaintances. Consequently, users often struggle to decide which version of themselves ④to present, knowing that a joke suitable for close friends might seem unprofessional to a supervisor. This tension forces many users to either self-censor heavily or maintain multiple separate accounts ⑤tailored to different audiences.

Psychologist John Suler proposed a concept called the online disinhibition effect, describing how people behave differently on the internet than they do face to face. Because usernames often hide real identities and screens create physical distance from others, individuals feel freer to express themselves without immediate social consequences. This freedom can be ①beneficial, allowing shy people to share honest feelings they would normally hesitate to reveal in person. However, the same anonymity frequently produces a ②darker outcome, encouraging users to post cruel comments they would never say to someone's face. ③Malicious remarks left under celebrities' photos or news articles illustrate how quickly this behavior can spread once a few users set the tone. Such comments often cause ④severe emotional harm to the people who receive them. Therefore, users must recognize that a screen does not erase moral responsibility, and platforms should ⑤weaken accountability rather than letting anonymity excuse harmful conduct.

Fast fashion refers to ①cheap, trendy clothing produced quickly and replaced almost as fast as it is bought. Because these garments are designed to be worn only a few times, huge amounts of fabric end up in landfills every year, and the dyeing process ②pollutes rivers near factories. In contrast, a ③growing number of brands are turning toward the circular economy, an economic model in which materials are reused, repaired, or recycled instead of being thrown away after a single use. For example, some companies ④collect old clothes, break down the fibers, and weave them into new fabric, while others let customers rent outfits for special occasions rather than buying garments they will barely wear. These approaches keep resources circulating within the system longer, ⑤increasing demand for raw materials. Therefore, shifting from a throwaway habit toward a circular one may be essential for making the fashion industry sustainable.

Sociologists use the term homophily to describe the tendency of people to form connections with others who share ①different backgrounds, opinions, or interests. This principle explains why classmates from the same major often become close friends, while coworkers with shared hobbies naturally gravitate toward one another. Because similarity reduces the effort required to understand another person's perspective, relationships built on shared traits tend to feel ②comfortable and require less negotiation. However, this same comfort can ③narrow the range of viewpoints someone encounters, since surrounding oneself with similar people limits exposure to different ideas. Social media platforms intensify this pattern through recommendation algorithms that suggest new friends based on shared interests or similar browsing history. As a result, users often find their online circles becoming increasingly ④homogeneous, filled with people who think and behave much like themselves. Recognizing this tendency allows individuals to make ⑤deliberate efforts to broaden their social networks.

Sleep is not a single, uniform state but a cycle that alternates between two very different modes: REM (rapid eye movement) sleep and non-REM sleep. During non-REM sleep, especially its deepest stage, the brain waves slow down dramatically, the body temperature drops, and tissue repair and growth hormone release reach their peak. This is the period most closely associated with physical restoration. REM sleep, by contrast, brings rapid eye movements, near-total muscle paralysis, and brain activity that closely resembles wakefulness. Most vivid dreaming occurs during this stage, and researchers believe _______________. A healthy night typically cycles through both stages four or five times, with non-REM dominating the early hours and REM periods lengthening toward morning. Disrupting either stage, through frequent awakenings or alcohol use, can leave a person feeling unrested even after a full night in bed.

Companies have discovered that ordinary advertisements no longer capture the attention of young consumers as effectively as they once did. (A) As a result, many brands now spend a large portion of their advertising budgets on influencer partnerships rather than television commercials. (B) This is because influencers build long-term relationships with their audiences, which makes recommendations feel personal rather than commercial. (C) However, brands must choose their partners carefully, since an influencer's reputation can directly affect how a product is perceived.

Feed an AI music program a mood, a tempo, and a rough genre, and within seconds it can generate a complete instrumental track. (A) The software has studied thousands of existing songs, learning which chord progressions and rhythms tend to sound pleasant together, and it recombines these patterns into something new. (B) For independent creators who cannot afford a composer or expensive licensing fees, this has been a genuine breakthrough. (C) Professional musicians, however, remain divided, since a flood of AI-generated background music could quietly push human composers out of smaller, lower-budget projects.

These physiological adjustments, though subtle, translate into a noticeable difference once competition actually begins. Skipping a proper warm-up before intense exercise might seem like a harmless way to save a few minutes, but the practice carries real physiological costs. ( ① ) A cold muscle is stiffer and less elastic than a warm one, making it considerably more prone to strains and tears when suddenly asked to contract forcefully. ( ② ) Gradually raising body temperature through light activity increases blood flow to the muscles, allowing oxygen to reach tissue more efficiently and enabling nerve signals to travel faster between the brain and the muscle fibers. A proper warm-up also raises heart rate gradually, easing the cardiovascular system into strenuous work rather than shocking it with a sudden demand. ( ③ ) Athletes who warm up thoroughly tend to report better performance in the early minutes of competition, since their bodies are already primed rather than adjusting on the fly. ( ④ ) For this reason, coaches treat warm-up routines not as optional preparation but as an essential part of training itself. ( ⑤ )

주어진 문장: Without such improvements, even the most generous rewards program cannot compensate for a disappointing product. Building brand loyalty has traditionally been considered one of the most valuable goals in marketing, since loyal customers tend to spend more and recommend products to others. ( ① ) Companies invest significant resources in loyalty programs, offering points, discounts, and exclusive access to encourage repeat purchases. ( ② ) However, some critics argue that these programs manipulate consumers into staying with a brand out of habit rather than genuine satisfaction. ( ③ ) Genuine loyalty, they contend, should be earned through consistent quality and honest treatment of customers. ( ④ ) Furthermore, excessive focus on retaining existing customers can cause companies to neglect innovation, since they assume loyal buyers will continue purchasing regardless of improvements. ( ⑤ ) As markets become more competitive, relying solely on loyalty programs without addressing underlying product quality may ultimately backfire.
