A documentary director named Mira first traveled to a remote Arctic glacier to film its towering cliffs of blue ice, which seemed frozen in time. Standing before the ①<u>massive</u> wall, she assumed such an enormous structure could hardly change within a lifetime. Five years later, however, she returned to the very same coordinates, expecting her camera to capture an identical scene. Instead, she discovered that the glacier had ②<u>retreated</u> so dramatically that the ice cliffs, once visible from her original position, had nearly ③<u>disappeared</u>, leaving bare rock and pools of meltwater behind. Comparing the two sets of footage side by side, Mira realized that a transformation she had expected to take centuries was actually happening within a single decade. This encounter convinced her that climate change, which she had previously regarded as a ⑤<u>distant</u> statistic, was in fact a ④<u>trivial</u> process reshaping landscapes before her eyes.

A growing number of health apps now track steps, sleep, and heart rate throughout the day, quietly building a detailed picture of a user's physical condition without requiring a single visit to a doctor's office. By comparing this stream of data against patterns drawn from millions of other users, the app's algorithm can ① flag early warning signs, such as an irregular heartbeat, long before the person experiencing it would have noticed anything unusual on their own. For people living far from specialists or unable to afford frequent checkups, this kind of constant monitoring can feel like a genuine ② safety net. Doctors caution, however, that these apps are designed to ③ diagnose illness, not merely to detect patterns, and that a worried user should always confirm any alarming reading with a professional rather than trusting an app's suggestion alone. Treating a wellness app as a ④ substitute for medical expertise, they warn, can be just as risky as ⑤ ignoring a warning altogether.

VO2 max, defined as the maximum volume of oxygen a person's body can consume and use during intense exercise, is widely regarded as one of the best single indicators of cardiorespiratory fitness. Elite endurance athletes typically post VO2 max values far higher than those of untrained individuals. While genetics accounts for a substantial portion of an individual's potential VO2 max, consistent aerobic training can still raise the measurement considerably over months of dedicated effort. It is worth noting, however, that a high VO2 max does not guarantee success in competition, since _______________.

Sociologists use the term homophily to 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 built on shared traits tend to feel comfortable and require less negotiation. However, this same comfort can narrow 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 homogeneous, filled with people who think and behave much like themselves. Recognizing this tendency _______________.

Opening most camera apps today reveals a row of filters that can smooth skin, brighten eyes, and reshape a jawline before a photo is even taken. What began as a playful novelty has become a default setting for many users, subtly adjusting nearly every selfie posted online. Psychologists have grown concerned about a specific consequence of this shift: _______________. Some social media platforms have responded by labeling heavily edited photos or banning certain filters that alter body shape.

The concept of energy management has gained popularity among workplace researchers who study how people sustain productivity throughout the day. (A) For this reason, experts recommend that people identify the hours when they naturally feel most alert and schedule their most demanding tasks during those windows. (B) Unlike time, which passes at the same rate for everyone, personal energy fluctuates throughout the day depending on factors such as sleep and nutrition. (C) Simple or repetitive tasks, on the other hand, can be handled during low-energy periods without much loss in quality.

Psychologists have long debated why some people find it easier than others to wait for future rewards. (A) For example, children who distracted themselves by singing or looking away were far more successful at waiting. (B) One explanation involves specific strategies, such as focusing attention away from the tempting object. (C) In the original marshmallow studies, researchers observed that success depended heavily on how children managed their attention.

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. (A) These small 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. (B) Over months of use, the system becomes noticeably better at anticipating needs, often adjusting settings moments before a resident would have reached for a switch. (C) Yet convenience comes with a trade-off that many households overlook, since a detailed record of daily habits is quietly being stored somewhere beyond their immediate control.

주어진 문장: Not everyone, however, feels this financial burden equally, since household circumstances vary widely. The term green premium describes the extra cost that consumers must pay when they choose an environmentally friendly product or energy source over a conventional, cheaper alternative. ( ① ) For example, an electric vehicle or solar-powered appliance often carries a higher price tag than its gasoline-powered or coal-based counterpart, even though it produces fewer emissions over time. ( ② ) This price gap frequently discourages shoppers who support sustainability in principle but cannot justify the additional expense within a limited household budget. ( ③ ) In contrast, wealthier consumers can absorb the premium more easily, which creates unequal participation in green markets. ( ④ ) To narrow this gap, governments have introduced subsidies and tax credits that lower upfront costs, while companies invest in research to make clean technologies cheaper to manufacture. ( ⑤ ) As production scales up and innovation continues, many economists expect the green premium to shrink steadily, eventually making sustainable choices the more affordable option for most consumers.

주어진 문장: Unlike traditional employees, these workers are typically classified as independent contractors. 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. Digital platforms now connect customers directly with drivers, designers, writers, and countless other independent workers within minutes. ( ① ) 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. ( ② ) For many young people entering the job market, gig work provides valuable flexibility that traditional employment rarely allows. ( ③ ) However, gig workers often lack benefits such as health insurance, paid leave, and retirement savings, which full-time employees typically receive. ( ④ ) Because their income can fluctuate sharply from month to month, many gig workers struggle to plan their finances confidently. ( ⑤ ) As this sector continues to expand, governments face growing pressure to design policies that protect independent workers.
