Sociologists use the term homophily ①to describe the tendency of people to form connections with others who share similar 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 ②built on shared traits tend to feel comfortable and require less negotiation. However, this same comfort can narrow the range of viewpoints someone ③encounters, since surrounding oneself with similar people limits exposure to different ideas. Social media platforms intensify this pattern through recommendation algorithms that ④suggest new friends based on shared interests or similar browsing history. As a result, users often find their online circles becoming increasingly homogeneous, filled with people who think and behave much like themselves. Recognizing this tendency ⑤allow individuals to make deliberate efforts to broaden their social networks.

Setting a goal such as 'I will study harder' rarely ①leads to meaningful improvement. According to psychologists Edwin Locke and Gary Latham, specific and challenging goals ②produce far better performance than vague or easy ones. This idea, known as goal-setting theory, suggests ③that clear targets direct attention and sustain effort over time. To apply this theory effectively, many educators recommend the SMART framework, which ④require goals to be Specific, Measurable, Achievable, Relevant, and Time-bound. Because the goal includes a clear number and a deadline, progress becomes easy ⑤to track and evaluate.

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.

Automation is transforming labor markets more ①quickly than economists predicted a decade ago. Factories once staffed by hundreds of workers now rely on robotic arms that assemble products with remarkable ②precision. This shift does not simply eliminate jobs; it also creates roles that never existed before, so technicians who maintain robotic equipment are now in high ③demand. Companies that invested early in automation often report steady increases in productivity, since machines handle repetitive tasks while employees focus on ④creative problem-solving. Without proper retraining support, the benefits of automation may not be shared fairly, ⑤narrowing inequality between skilled and unskilled labor.

A smart thermostat that learns a family's daily rhythm can lower the temperature automatically before everyone wakes up cold, while smart lights that follow a resident's schedule no longer need to be switched on and off by hand. These small ① conveniences rest on a shared foundation: sensors collect data about temperature, motion, and light throughout the home, and an algorithm gradually learns which settings match each household's actual habits rather than a factory default. Over months of use, the system becomes noticeably ② better at anticipating needs, often adjusting settings moments before a resident would have reached for a switch. Yet convenience comes with a trade-off that many households ③ overlook. Every one of these small adjustments depends on constant data collection, meaning that a detailed record of daily habits is quietly being ④ stored somewhere ⑤ beyond their immediate control, giving residents full and constant access to exactly how it is used.

The gig economy, in which people take on short-term or freelance jobs instead of full-time positions, has grown rapidly over the past decade. This model offers clear advantages: workers can choose when and how much they work, and businesses can hire help only when they actually need it. For many young people entering the job market, gig work provides valuable flexibility that traditional employment rarely allows. However, gig workers often ___________, which full-time employees typically receive. Because their income can fluctuate sharply from month to month, many gig workers struggle to plan their finances confidently.

Adaptive learning apps promise something no traditional classroom can easily offer: a lesson plan that adjusts itself to each individual student in real time. (A) As a student answers practice questions, the app tracks which concepts are mastered and which remain shaky, then quietly reshuffles the next set of problems to target the weaker areas. (B) Early studies suggest that this personalized pacing can help struggling students catch up faster than a one-size-fits-all worksheet ever could. (C) However, critics caution that an app cannot replace the encouragement, humor, and flexibility a human teacher brings to a lesson.

One of the clearest examples of this involves a specific protein that stimulates the growth of new brain cells. Exercise does far more than strengthen muscles and the heart; it also produces measurable changes within the brain itself. ( ① ) During sustained physical activity, the body releases a protein called brain-derived neurotrophic factor, which supports the growth of new neurons and strengthens connections between existing ones, particularly in regions associated with memory and learning. ( ② ) Studies comparing physically active students to sedentary peers have repeatedly found that the active group performs better on tests of attention and problem-solving, even when the exercise session ends well before the test begins. ( ③ ) Researchers believe that exercise increases blood flow to the brain, delivering oxygen and nutrients more efficiently, while also reducing levels of stress hormones that can interfere with clear thinking. ( ④ ) Interestingly, aerobic activities such as running or swimming appear to produce more pronounced cognitive benefits than purely strength-based training. ( ⑤ )

Some welcome the tool as a quick way to sketch ideas before refining them by hand. Feed an AI music program a mood, a tempo, and a rough genre, and within seconds it can generate a complete instrumental track, ready to be dropped under a video or used as background music for a small business. ( ① ) 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 rather than copying any single source directly. ( ② ) For independent creators who cannot afford a composer or expensive licensing fees, this has been a genuine breakthrough. ( ③ ) Professional musicians, however, remain divided. ( ④ ) Others worry that a flood of AI-generated background music could quietly push human composers out of smaller, lower-budget projects, the very jobs many musicians once relied on to build a career. ( ⑤ )

주어진 문장: Even small purchasing decisions, they argue, can accumulate into meaningful pressure on how companies operate. Value-based consumption refers to the practice of spending money on products or experiences that align with a person's personal beliefs, even if cheaper alternatives exist. ( ① ) Rather than simply seeking the lowest price, value-conscious consumers consider factors such as labor conditions, environmental impact, and community benefit before making a purchase. ( ② ) Some critics dismiss this approach as impractical, arguing that most people cannot afford to prioritize ethics over affordability in daily life. ( ③ ) However, supporters point out that value-based spending does not require constant sacrifice; it often means buying fewer, higher-quality items rather than accumulating cheap goods that wear out quickly. ( ④ ) This shift also encourages companies to improve their practices, since consumer demand increasingly rewards transparency and responsibility. ( ⑤ ) For example, a clothing brand that openly shares its supply chain information may attract loyal customers willing to pay slightly more.
