When the body fights off an infection, the immune system relies heavily on ①adequate sleep to function effectively. During deep sleep, the body produces and releases cytokines, proteins ②that help regulate immune responses and coordinate the fight against harmful invaders. People who consistently sleep fewer than six hours a night ③shows measurably weaker antibody responses after vaccination compared with those who sleep seven or eight hours. Chronic sleep deprivation also appears ④to promote low-grade inflammation throughout the body, a state that has been linked to a higher risk of heart disease. Rather than being a passive state, sleep functions as an active period during which the immune system ⑤repairs itself and prepares for future threats.

Adaptive learning apps promise something no traditional classroom can easily offer: a lesson plan ①that adjusts itself to each individual student in real time. As a student answers practice questions, the app tracks which concepts are mastered and which remain shaky, then quietly ②reshuffles the next set of problems to target the weaker areas. Early studies suggest that this personalized pacing can help struggling students ③catch up faster than a one-size-fits-all worksheet ever could. However, critics caution that an app cannot replace the encouragement, humor, and flexibility a human teacher brings to a lesson, especially when a student ④frustrating rather than simply behind. There is also a subtler concern: students who grow used to instant, algorithm-generated feedback may struggle later with the slower, more ambiguous kind of feedback that real-world tasks and mentors typically ⑤provide.

After a viewer finishes an episode, a streaming service rarely leaves the choice of what to watch next entirely up to chance. Instead, a recommendation algorithm ①compares that viewer's habits with patterns drawn from millions of other users who watched similar content, then ranks thousands of titles in order of predicted interest. This approach keeps viewers ②disengaged far longer than a simple list of new releases ever could, which is precisely why streaming companies invest so heavily in refining it. The system is not without drawbacks, however. Because the algorithm favors titles similar to what a viewer already enjoys, it can quietly ③narrow someone's exposure to unfamiliar genres, directors, or cultures, creating a comfortable but repetitive bubble. Some platforms have begun inserting occasional wildcard suggestions, deliberately unrelated to past viewing habits, in an attempt to ④counteract this narrowing effect and keep recommendations from becoming too ⑤predictable.

Smart speakers have quietly become a fixture in many households, responding to spoken requests for weather updates, music, or kitchen timers. Because these assistants improve by learning from millions of interactions, they gradually become better at recognizing regional accents and casual phrasing that once confused them. Still, _______________. Engineers continue to refine these systems, but many admit that truly natural conversation remains one of the hardest goals in the entire field of artificial intelligence.

Every day, email providers quietly block billions of unwanted messages before they ever reach a user's inbox. The filter examines each incoming message for suspicious patterns, including certain keywords, unusual sender addresses, and formatting tricks. What makes the system effective is that it keeps learning after launch: whenever a user marks a message as spam, that action becomes new training data, sharpening the filter's future decisions. This creates a constant back-and-forth, since spammers study which messages get blocked and then adjust their wording to slip through again. As a result, _______________.

A navigation app calculating a route rarely relies on distance alone; instead, it constantly weighs real-time traffic reports, past congestion patterns, and even data from other drivers' phones currently on the road. This flood of information allows the app to reroute a driver away from a sudden accident within seconds. The convenience comes at a cost that few passengers consider, however. When thousands of drivers are simultaneously redirected onto the same shortcut, _______________, arguing that an algorithm optimizing for individual convenience can end up creating a new, entirely different problem for the wider community.

Many economists have studied how automation affects different sectors of the economy, and their research reveals a consistent pattern. (A) For example, manufacturing plants that adopted robotics saw production speed double within five years, while the number of routine assembly jobs fell sharply. (B) As a result, workers today are encouraged to develop skills that complement machines rather than compete with them, such as creativity and critical thinking. (C) At first, automation mainly affected repetitive manual tasks in manufacturing, but it has since spread into administrative and even creative fields.

Jiho's path into entrepreneurship began almost by accident, far from the corporate career his parents had imagined for him. (A) Despite warnings from relatives who considered the plan too risky, Jiho and his teammates decided to delay job applications and pursue the idea further. (B) A class project he joined during his final year gradually evolved into something more serious, as restaurants began placing regular orders through their prototype. (C) That decision eventually paid off, as the team secured a small investment after nearly failing twice.

주어진 문장: This concern reflects a deeper fear about what makes art meaningful in the first place. Artificial intelligence has begun to play a surprising role in creative industries once thought to be uniquely human. ( ① ) Programs can now compose music, generate paintings, and even draft short stories within seconds. ( ② ) Some artists welcome this technology, using AI tools to explore new styles or overcome creative blocks that once took weeks to resolve. ( ③ ) Others, however, argue that AI-generated art lacks the emotional depth that comes from genuine human experience. ( ④ ) Despite this debate, most experts agree that AI is unlikely to fully replace artists anytime soon. ( ⑤ ) Instead, it functions best as a collaborative tool, helping creators experiment faster while leaving final artistic decisions to humans.

Because the keyboard nudges people toward its own suggestions, some linguists worry that autocomplete may be quietly narrowing everyday vocabulary. Long before a user finishes typing a sentence, the keyboard on most smartphones has already begun guessing what word comes next. ( ① ) This feature relies on a language model trained to notice which words commonly follow one another, so it can offer a shortlist of likely candidates above the keyboard, saving users countless keystrokes over the course of a day. ( ② ) The system also adapts to each individual, gradually learning a person's favorite phrases, slang, and even the names of friends that no generic dictionary would recognize. ( ③ ) This constant personalization, however, creates a subtle side effect that few users notice. ( ④ ) This small habit, choosing a convenient suggestion rather than searching for the more precise or original word one might otherwise have chosen, can add up over years of daily use. ( ⑤ )
