A flexitarian is someone who mainly ①eating plant-based meals but occasionally includes meat or fish, unlike a strict vegetarian who avoids animal products entirely. This flexible diet has recently gained attention as a practical way to fight climate change, since raising livestock ②produces a significant portion of global greenhouse gas emissions. Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at ③trapping heat in the atmosphere. By replacing just a few meat-based meals each week with vegetables, grains, or legumes, individuals can noticeably shrink their carbon footprint without giving up meat completely. Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it ④allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a realistic first step, ⑤believing that gradual change, rather than sudden restriction, is more likely to spread widely across society.

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

Time-management researchers frequently mention a principle known as Parkinson's Law, which states that work ①expands to fill the time available for its completion. According to this idea, a task that could be finished in one hour will often stretch to fill an entire afternoon if that much time is scheduled for it. Students who set ②vague deadlines frequently experience this effect, spending extra hours refining a report that was already ③complete. Employees given a full week for a simple project may also delay meaningful progress until the final days, even though the actual work requires far ④more effort. This pattern happens partly because people unconsciously adjust their pace to match perceived urgency. Setting shorter, more specific deadlines can ⑤counter this tendency, forcing tasks to fit within a tighter and more realistic window.

Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. This theory explains that every habit ①begins with a cue, a signal that tells the brain to start an ②automatic behavior. The brain then performs a routine, which is the action itself, whether physical or mental. Finally, the brain receives a reward, a ③negative feeling that makes it want to ④repeat the same behavior. For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run almost without ⑤conscious thought. Because this loop operates automatically, breaking a bad habit requires changing the routine while keeping the same cue and reward. Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.

After an especially demanding training session, the instinct to collapse onto a couch and remain motionless is understandable, yet exercise physiologists increasingly recommend the opposite approach. Active recovery involves performing low-intensity movement, such as a light jog, an easy swim, or a gentle bike ride, on days following intense exertion rather than resting completely, since _______________. Some athletes worry that any movement at all will interfere with the repair process, but research suggests that truly light activity does not meaningfully slow healing and may even reduce the perceived soreness that follows a hard session.

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 massive 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 retreated so dramatically that the ice cliffs, once visible from her original position, had nearly disappeared, leaving bare rock and pools of meltwater behind. Comparing the two sets of footage side by side, Mira realized that _______________. This encounter convinced her that climate change, which she had previously regarded as a distant statistic, was in fact an urgent process reshaping landscapes before her eyes.

Psychologist Roy Baumeister proposed a concept called ego depletion theory, which suggests that ___________. According to this theory, every act of self-control, from resisting a snack to concentrating on difficult homework, draws from the same limited mental resource. As this resource becomes depleted throughout the day, later decisions require more effort and are more likely to fail. For instance, someone who exercises discipline avoiding distractions all morning may struggle to resist checking a phone by evening. Likewise, dieters report that self-control weakens sharply at night, after hours of resisting food. Some researchers argue that short breaks, adequate sleep, and blood sugar levels can help restore this depleted resource. Although later studies have questioned how strong this effect is, the theory still offers a useful framework for understanding why willpower seems to fade throughout a long day.

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.

주어진 문장: This is precisely why scientists treat these thresholds with such urgency, rather than viewing them as distant, abstract possibilities. Climate scientists frequently warn about tipping points, thresholds beyond which a small additional change triggers a large, often irreversible shift in the climate system. ( ① ) Unlike gradual warming, which unfolds steadily over decades, crossing a tipping point can produce dramatic consequences within a short period. ( ② ) For instance, as Arctic ice melts, it exposes darker ocean water that absorbs more sunlight than reflective ice, accelerating further melting in a self-reinforcing cycle. ( ③ ) Similarly, scientists worry that a major ocean current, which currently redistributes heat across the planet, could slow dramatically if enough freshwater from melting glaciers dilutes the surrounding seawater. ( ④ ) Once such thresholds are crossed, restoring the original balance may become nearly impossible, even if emissions are later reduced. ( ⑤ ) Therefore, researchers argue that preventing these transitions matters more than merely slowing average temperature increases. Identifying how close each system stands to its threshold remains one of the most urgent challenges in climate research.

주어진 문장: Researchers have found that people who use this method are significantly more likely to follow through on their goals than those who rely on willpower alone. Last January, Minji wrote the same resolution she always wrote: study English for an hour every day. ( ① ) By February, she had already quit, just as in previous years. Frustrated, she asked her teacher why her willpower always failed, and learned about a concept called implementation intentions. ( ② ) This idea, developed by psychologists, means forming a specific if-then plan that links a certain situation to a certain action in advance. ( ③ ) Instead of vaguely intending to study more, Minji made a precise plan: if she finished dinner, then she would study for thirty minutes. ( ④ ) She also prepared a backup plan: if she felt too tired, then she would study for just ten minutes instead of skipping entirely. ( ⑤ ) Because these plans removed the need to decide anything in the moment, starting became far easier for Minji. By December, she had studied for eleven straight months, proving that clear if-then plans beat vague intentions.
