Anyone who has ridden a bicycle after a decade away from one has likely experienced muscle memory firsthand: the body seems to ①recall a complex skill almost instantly, even when conscious memory of the exact movements has faded. Contrary to what the name suggests, muscles themselves do not actually store memories; the phenomenon originates in the brain and nervous system, where repeated practice gradually ②hides control of a well-learned movement from regions associated with conscious thought to areas that operate largely automatically. This shift explains why a skilled athlete can execute a complicated sequence of movements without consciously thinking through each individual step, ③freeing mental attention for strategy and decision-making instead. Interestingly, research also suggests that these neural pathways can remain ④partially intact even after long periods without practice, which is why relearning a skill is typically much faster than learning it for the very first time. Coaches often exploit this principle by ensuring that fundamental techniques are practiced correctly from the very ⑤beginning.

A navigation app calculating a route rarely relies on distance alone; instead, it constantly weighs real-time traffic reports, past congestion patterns for that time of day, and even data from other drivers' phones currently on the road. This flood of information allows the app to ①reroute a driver away from a sudden accident within seconds, often before the driver has any idea the accident occurred at all. The convenience comes at a ②cost that few passengers consider, however. When thousands of drivers are simultaneously redirected onto the same shortcut, that quiet side street can quickly become as ③congested as the highway it was meant to help travelers avoid. Residents of these once-quiet neighborhoods have increasingly ④complained about the sudden surge of unfamiliar traffic, arguing that an algorithm optimizing for individual convenience can end up ⑤solving a new, entirely different problem for the wider community.

Artificial intelligence has begun to play a surprising role in creative industries once thought to be uniquely human. Some artists ①welcome this technology, using AI tools to explore new styles or overcome creative blocks that once took weeks to resolve. Others, however, argue that AI-generated art ②lacks the emotional depth that comes from genuine human experience. Despite this debate, most experts agree that AI is unlikely to fully ③replace artists anytime soon. Instead, it functions best as a collaborative tool, helping creators experiment ④faster while leaving final artistic decisions to humans. Therefore, artists who learn to work alongside AI may find themselves with a distinct ⑤disadvantage in this rapidly changing industry.

Three-dimensional printing technology is changing how products are designed and manufactured across many industries. Unlike traditional manufacturing, which often requires expensive molds and long production times, ___________. This flexibility allows companies to produce small batches of customized products without the massive costs typically associated with mass production.

Climate scientists frequently warn about tipping points, _______________. Unlike gradual warming, which unfolds steadily over decades, crossing a tipping point can produce dramatic consequences within a short period. 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. 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. Once such thresholds are crossed, restoring the original balance may become nearly impossible, even if emissions are later reduced. 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.

Temporal discounting offers a useful lens for understanding why long-term goals so often lose out to short-term pleasures. (A) Consequently, replacing distant, abstract goals with smaller, immediate milestones can make future rewards feel psychologically closer and more motivating. (B) Research shows that people consistently prefer a smaller reward available today over a considerably larger reward promised weeks later. (C) This preference persists even when the delayed reward is clearly the more rational choice, revealing how strongly immediacy influences decision-making.

Climate change deniers often seem to ignore evidence that contradicts their views, and psychologists have a specific explanation for this behavior. (A) For example, someone whose job depends on fossil fuels may search for reasons to doubt the data, even while insisting that they respect science. (B) This concept, called motivated reasoning, describes how people process information in ways that protect their existing beliefs and lifestyles rather than pursue objective truth. (C) Rather than being a simple failure of intelligence, this pattern reflects a well-documented psychological tendency studied for decades.

Food choices are increasingly recognized as a powerful tool in the fight against climate change. (A) 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 allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a realistic first step, believing that gradual change, rather than sudden restriction, is more likely to spread widely across society. (B) A flexitarian is someone who mainly eats 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 produces a significant portion of global greenhouse gas emissions. (C) Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at trapping heat in the atmosphere.

주어진 문장: Still, the risk of falling behind outweighs the discomfort of constant adjustment, most experts say. As technology continues to reshape nearly every profession, the idea of finishing education after graduation has become outdated. ( ① ) Workers who once expected their initial training to last an entire career now find that skills can become obsolete within just a few years. ( ② ) Lifelong learning, therefore, has shifted from being an optional pursuit to a practical necessity for staying competitive in the job market. ( ③ ) Many professionals now take short online courses, attend workshops, or earn new certifications while continuing to work full-time. ( ④ ) Critics argue that constant learning can be exhausting and difficult to balance with personal responsibilities. ( ⑤ ) In a rapidly changing economy, the ability to learn continuously may matter more than any single degree.

주어진 문장: Some researchers even suggest that painting rooftops white could further help reflect sunlight away from buildings. On a summer evening, downtown streets often feel noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. ( ① ) This phenomenon, known as the urban heat island effect, occurs when cities retain more heat than surrounding rural areas because of their dense concentration of asphalt, concrete, and buildings. ( ② ) Unlike soil or vegetation, which absorb and release heat gradually, these man-made surfaces absorb sunlight during the day and slowly radiate it back at night, preventing temperatures from cooling. ( ③ ) Tall buildings packed closely together also block wind, trapping warm air within narrow streets. ( ④ ) In contrast, areas with abundant trees and open water naturally stay cooler, since plants release moisture that helps lower surrounding temperatures. To reduce this effect, many cities have begun installing rooftop gardens and expanding public parks, hoping that additional greenery will absorb less heat than pavement does. ( ⑤ )
