Modern advertising increasingly relies on personal data ①collected from users' browsing habits, search histories, and social media activity. Companies argue that this approach benefits consumers by showing advertisements that are more relevant to their actual interests. However, many critics contend that this level of tracking raises serious concerns about privacy, since users rarely understand how extensively their behavior ②is being monitored. Some algorithms can predict purchasing decisions before consumers themselves are consciously aware of them, ③which feel unsettling to many people. Furthermore, personalized advertising can trap users in a narrow bubble, repeatedly showing them similar products and ④limiting their exposure to alternatives. Supporters counter that consumers who dislike targeted ads can simply ⑤adjust their privacy settings.

Artificial intelligence has begun to play a surprising role in creative industries ①once thought to be uniquely human. Programs can now compose music, generate paintings, and ②draft short stories within seconds. Some artists welcome this technology, ③used AI tools to explore new styles or overcome creative blocks that once took weeks to resolve. Others, however, argue that AI-generated art lacks the emotional depth ④that comes from genuine human experience. Therefore, artists who learn to work alongside AI, rather than compete against it, may find themselves ⑤with a distinct advantage.

For centuries, dreams have ①fascinated scientists and philosophers alike, yet no single theory fully explains why the sleeping brain generates such vivid and often bizarre experiences. One prominent idea suggests that dreaming helps the brain process emotional experiences, replaying difficult events in a ②safe, low-stakes environment so that their emotional intensity gradually fades. Another theory proposes that dreams serve a more practical function, allowing the brain to ③ignore responses to threats without any real danger, a kind of nightly simulation that may have offered early humans a survival advantage. Still other researchers argue that dreaming is simply a byproduct of the brain organizing memories, with vivid imagery arising as the mind sorts through the day's ④information rather than serving any independent purpose of its own. Because these theories rest on indirect evidence, none has been ⑤conclusively proven.

Climate scientists frequently warn about tipping points, thresholds beyond which a small additional change triggers a large, often irreversible shift in the climate system. Unlike ①gradual warming, which unfolds steadily over decades, crossing a tipping point can produce ②dramatic 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-⑤reinforcing 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 ③possible, 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 ④urgent challenges in climate research.

Parents and coaches sometimes worry that heavy resistance training might damage the growth plates in a young athlete's bones, cartilage regions near the ends of long bones responsible for lengthening as a child develops. This concern kept strength training out of many youth programs for decades. However, extensive research over the past twenty years has found little evidence that properly supervised resistance training harms growth plates in healthy children, since _______________. Major pediatric and sports medicine organizations now generally agree that structured strength programs, when taught with correct form and appropriate weight, can safely improve bone density, coordination, and injury resistance in young athletes.

Some changes in habit begin not with a big decision but with a quiet moment that lingers in the mind. (A) That changed when her class was assigned a documentary about plastic waste drifting through the ocean, footage she initially expected to find boring. Instead, watching seabirds mistake plastic fragments for food left her strangely unsettled, and she found herself thinking about the assignment long after class ended. (B) The next morning, almost without deciding to, she slipped her old tumbler into her backpack instead of buying a disposable cup on the way to school. It felt like a small, meaningless gesture at first. However, as weeks passed, she realized that consistently choosing the tumbler, declining a plastic straw, and reusing a shopping bag were quietly adding up. Small choices, she discovered, become meaningful once repeated. (C) Until last spring, Minji rarely thought twice about tossing a paper cup into the trash after finishing her coffee. Environmental issues seemed distant, something scientists and politicians should handle rather than an ordinary student like her.

Elite athletes often perform in front of enormous crowds with championships, contracts, and years of training riding on a single moment, and the psychological weight of that pressure can undermine skills that feel automatic in practice. (A) Structured breathing exercises and pre-performance routines also help athletes regain a sense of control before a decisive moment. (B) Rather than trying to eliminate nervousness entirely, which research suggests is nearly impossible, many trainers now teach athletes to reinterpret the physical symptoms of anxiety as signs of readiness rather than danger. (C) Sports psychologists explain that intense anxiety narrows attention and disrupts the smooth, unconscious execution of well-learned movements, a phenomenon sometimes called choking under pressure.

Soojin's rise as a content creator did not happen overnight, despite how it may have appeared to outsiders. (A) One video demonstrating a simple recipe, however, unexpectedly reached millions of viewers and changed everything almost instantly. (B) For months, she posted consistently despite earning very little attention, often doubting whether she should continue at all. (C) After that unexpected success, brands began reaching out, eventually allowing her to earn more than most entry-level jobs would pay.

주어진 문장: In other words, the promised environmental benefit is far less certain than it first appears. To compensate for their carbon emissions, many individuals and companies now purchase carbon offsets, financial credits that fund projects such as planting trees or building renewable energy plants. ( ① ) The idea is appealing: paying for an equivalent amount of carbon to be absorbed elsewhere should cancel out the harm caused by activities like flying. ( ② ) However, critics argue that this system often functions as a convenient excuse for postponing genuine emission cuts rather than achieving them. ( ③ ) For example, a newly planted forest may take decades to absorb the promised carbon, and it could later burn down or be cut, erasing any benefit. ( ④ ) Moreover, some offset projects would have happened anyway, meaning the credits fund nothing truly additional. ( ⑤ ) Therefore, relying heavily on offsets allows businesses to maintain harmful practices while appearing responsible. Experts insist that offsetting should complement, not replace, direct reductions in fossil fuel use if the strategy is to remain credible.

주어진 문장: Fortunately, this cycle is not impossible to reverse. An echo chamber refers to an online environment where people are mainly exposed to opinions that already match their own beliefs. ( ① ) This phenomenon occurs because social media algorithms tend to recommend content similar to what users have previously liked or shared, gradually narrowing the range of perspectives they encounter. ( ② ) As a result, individuals inside an echo chamber rarely engage with viewpoints that challenge their existing assumptions, which allows their original beliefs to grow increasingly extreme over time. ( ③ ) For example, someone who frequently reads articles supporting one political party may begin to see the opposing party as entirely unreasonable, having never seriously considered its arguments. ( ④ ) Political polarization, a significant issue in many countries today, is often linked to this pattern of selective exposure. ( ⑤ ) Breaking out of an echo chamber requires deliberately seeking information from diverse sources, even when those sources present uncomfortable or unfamiliar ideas.
