Browsing an online store today often means ① chatting with an AI assistant that asks a few quick questions, such as budget or intended use, before suggesting a short list of products tailored to the answers. Unlike a static list of best-sellers, this assistant can adjust its suggestions on the spot, ② responding to follow-up questions the way a knowledgeable salesperson might in a physical store. Retailers report that shoppers ③ who use these chatbots tend to complete purchases more often and return fewer items, since the guided conversation helps buyers choose products that actually fit their needs. Some shoppers, however, remain wary of how personal the questions can feel, ④ wonder how much of that conversation is quietly stored and reused to influence future purchases. Consumer advocates argue that stores should clearly explain what happens to this data, rather than ⑤ burying the explanation in a lengthy privacy policy.

Feed an AI music program a mood, a tempo, and a rough genre, and within seconds it can generate a complete instrumental track, ready to be dropped under a video or used as background music for a small business. The software has studied thousands of existing songs, learning which chord progressions and rhythms tend to sound ① pleasant together, and it ② recombines these patterns into something new rather than copying any single source directly. For independent creators who cannot afford a composer or expensive licensing fees, this has been a genuine ③ breakthrough. Professional musicians, however, remain divided. Some welcome the tool as a quick way to sketch ideas before refining them by hand, while others ④ celebrate that a flood of AI-generated background music could quietly push human composers out of smaller, lower-budget projects. ⑤ the very jobs many musicians once relied on to build a career.

Only a decade ago, translation apps produced sentences so ① awkward that users often laughed at the results rather than trusting them. Today, many of these apps rely on neural networks that analyze entire sentences at once, capturing context instead of translating word by word. This shift has made everyday tasks such as reading a foreign menu or chatting with an overseas friend remarkably ② chaotic. Frequent travelers now point their phone cameras at street signs and receive an ③ instant translation overlaid on the screen. Even so, the technology still struggles with humor, sarcasm, and cultural nuance, areas where a single wrong word can ④ completely change the intended meaning. For this reason, professional translators argue that these apps are best treated as a helpful ⑤ starting point rather than a final, polished result.

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.

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. Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at trapping 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 allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a realistic first step, believing that _______________.

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.

For this reason, nutritionists generally advise spreading moderate portions of protein evenly across several meals throughout the day rather than saving it all for one large post-workout meal. After a strenuous workout, muscle fibers experience thousands of microscopic tears, and the body immediately begins a repair process that ultimately makes the muscle stronger than it was before. ( ① ) This repair depends heavily on amino acids, the building blocks that protein supplies, which is why sports scientists recommend consuming protein within a couple of hours after training. ( ② ) Waiting too long to eat can slow recovery, since a muscle's sensitivity to amino acids gradually declines once that window closes. ( ③ ) Many athletes assume that eating an enormous quantity of protein in a single sitting will speed up this process. ( ④ ) But the body can only use a limited amount at once; the rest is simply burned for energy or stored as fat. ( ⑤ )

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: 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.

Some schools have begun asking students to submit an early draft alongside the final version, specifically to preserve evidence of a student's own original voice. Highlighting an awkward sentence and instantly seeing three smoother alternatives has become a routine part of writing for many students, thanks to AI writing assistants built into word processors and browsers. ( ① ) These tools check grammar and spelling, of course, but the more advanced versions go further, suggesting clearer phrasing, flagging repetitive words, and even adjusting tone to sound more formal or more casual depending on the purpose. ( ② ) Teachers generally welcome the grammar and spelling support, since it frees up class time to focus on argument and structure rather than comma placement. ( ③ ) Concerns grow, however, around the tone and phrasing suggestions, which can gradually nudge every student's writing toward a similar, polished style. ( ④ ) This makes it harder to tell an individual voice from a suggestion generated by the same underlying model. ( ⑤ )
