For decades, athletes were taught to stretch a muscle and hold the position before any competition, ① believing that this practice alone would prevent injury. Recent research, however, has complicated that assumption considerably. Static stretching, in which a muscle ② is held at its longest length for an extended period, can actually reduce the muscle's ability to generate explosive force immediately afterward. Dynamic stretching, which involves controlled, repeated movement through a joint's full range of motion, ③ appears to prepare muscles for activity without this temporary weakening effect. As a result, many coaches now recommend ④ to save static stretching for after a workout, when it may help restore muscle length and reduce soreness, while ⑤ reserving dynamic movements for the warm-up period before intense effort begins.

A growing number of health apps now track steps, sleep, and heart rate throughout the day, ① 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 flag early warning signs, such as an irregular heartbeat, long before the person ② 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 ③ feel like a genuine safety net. Doctors caution, however, that these apps ④ are designed to detect patterns, not to diagnose illness, and that a worried user should always confirm any alarming reading with a professional. Treating a wellness app as a substitute for medical expertise, they warn, can ⑤ being just as risky as ignoring a warning altogether.

Social psychologists describe a phenomenon called the bystander effect, in which individuals become less likely ①helping a victim as the number of witnesses increases. Each observer assumes someone else will step in, and this diffusion of responsibility leaves no one ②willing to act. Cyberbullying magnifies this problem, since a single humiliating post can be witnessed by thousands of people ③scattered across the internet rather than a few standing nearby. Anonymity intensifies the effect further, allowing silent observers ④to scroll past cruel comments without feeling accountable for their inaction. Some bystanders even worry that intervening publicly might make them the bully's next target, so they choose ⑤to remain silent instead.

When a price is crossed out and replaced with a lower number, consumers instinctively perceive the new price as a ①loss, even if the original price was rarely charged. Limited-time sales further ②intensify this effect, since a ticking clock encourages rushed decisions that leave little room for careful comparison. Retailers also use phrases such as "while supplies last" to suggest ③scarcity, even when inventory remains plentiful. Over time, frequent sales can actually train customers to wait for discounts rather than buy at full price, which can ④hurt long-term profits. Despite this risk, many companies continue relying on sales events because the short-term boost in customer traffic usually ⑤outweighs the potential downside.

Many companies now advertise themselves as environmentally responsible, yet a growing number of these claims turn out to be ①misleading. This practice, known as greenwashing, occurs when a business spends more effort marketing its products as eco-friendly than actually reducing environmental harm. A company might launch a recycled-packaging line while continuing to pollute rivers through its main factories, creating a false impression of genuine change. Such tactics ②deceive well-intentioned consumers who wish to shop responsibly but lack the tools to ③verify corporate claims. In contrast, truly sustainable businesses publish detailed, independently verified data about their emissions and supply chains, allowing outsiders to check their progress. Therefore, shoppers should look beyond vague labels like green or natural and instead search for ④recognized certifications, transparent reports, and measurable targets. Without such scrutiny, greenwashing will keep ⑤declining, undermining public trust and slowing the broader shift toward an economy that truly protects the planet.

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.

Telemedicine has sparked debate among healthcare professionals about its proper role in modern medicine. (A) Critics counter that virtual visits cannot fully substitute for physical examinations, which remain essential for diagnosing certain conditions accurately. (B) Most experts, weighing both sides, conclude that telemedicine works best as a complement to, rather than a replacement for, traditional care. (C) Supporters point out that virtual visits save time and extend healthcare access to patients living far from hospitals.

Open a music streaming app on any given morning, and a personalized playlist is usually already waiting, assembled overnight from songs the algorithm predicts will match a listener's current mood. (A) Musicians, meanwhile, have mixed feelings about this shift, since a song the algorithm decides not to promote may struggle to reach listeners no matter how well it was written. (B) Listeners often praise the feature for introducing them to artists they never would have searched for on their own, effectively acting as a tireless music scout working around the clock. (C) This prediction relies on far more than genre alone; the system studies skip rates, replay counts, and even the time of day a song is typically played to build a detailed profile of individual taste.

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. Every day, email providers quietly block billions of 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. ( ① ) The filter 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. ( ② ) What makes the system effective is that it keeps learning after launch. ( ③ ) This creates a constant back-and-forth, since spammers study which messages get blocked and then adjust their wording to slip through again. ( ④ ) As a result, spam filtering is less like a fixed wall and more like an ongoing contest, with each side continuously adapting to outsmart the other. ( ⑤ )

주어진 문장: After all, ignoring proven facts might seem like an irrational thing to do. When people encounter solid scientific evidence about climate change, we might expect them to accept it without hesitation. ( ① ) However, many individuals still dismiss or downplay such evidence, and psychologists explain this pattern through a concept called motivated reasoning. ( ② ) Motivated reasoning refers to the tendency to process information in a way that protects one's existing beliefs, identity, or lifestyle rather than to pursue objective truth. ( ③ ) For example, a person whose livelihood depends on the fossil fuel industry may unconsciously search for reasons to doubt climate data, even while claiming to value scientific accuracy. ( ④ ) This happens because accepting uncomfortable facts can threaten a person's sense of self or demand costly lifestyle changes. ( ⑤ ) Therefore, simply presenting more data rarely persuades a committed skeptic. Instead, experts suggest connecting climate information to values the person already holds, such as family safety or economic stability, so that acceptance feels natural rather than threatening.
