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.

Long before a user finishes typing a sentence, the keyboard on most smartphones has already begun ①guessing what word comes next. This feature relies on a language model ②trained 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. The system also adapts to each individual, gradually ③learning a person's favorite phrases, slang, and even the names of friends that no generic dictionary would recognize. This constant personalization, however, creates a subtle side effect that few users ④notices. Because the keyboard nudges people toward its own suggestions, some linguists worry that autocomplete may be quietly narrowing everyday vocabulary, encouraging writers ⑤to accept a convenient suggestion rather than searching for the more precise word.

Sunny Beach Rentals is now open for the summer season, offering a wide range of water equipment at ①affordable daily rates. To rent equipment, visitors simply need to show identification and pay a small deposit, which is fully ②kept when the items are returned in good condition. Equipment is checked carefully before and after each use to ensure everything remains ③clean and safe. Renters are asked to return all items by six in the evening, since the shop closes shortly after ④sunset. Damaged equipment must be reported ⑤immediately so that it can be replaced quickly.

Among the many tools available to those who design choice environments, few are as quietly ①powerful as the default option, the alternative that takes effect automatically unless a person actively selects something else. Because changing a default requires ②deliberate effort, many individuals simply accept whatever arrangement has been preselected for them, regardless of whether that arrangement actually serves their interests best. Countries that automatically enroll citizens in organ donation programs, requiring an explicit request to opt out, consistently report far ③lower donor registration rates than countries that require citizens to actively opt in. Employers who automatically enroll new hires in retirement savings plans likewise see participation rates climb dramatically compared with employers who leave enrollment entirely voluntary. What makes default options so influential is not merely convenience; a default also functions as an implicit signal about what is considered ④normal or recommended, subtly shaping perceptions even among individuals who believe themselves to be deciding ⑤independently.

Summer vacation is a great time to go camping, but a safe trip requires ①careful preparation. First, pack enough water and snacks, since staying hydrated is ②essential in hot weather. Second, bring sunscreen and insect repellent, which will ③expose your skin to sunburn and bug bites. Check the weather forecast before you leave, and choose a campsite that is ④safe from flooding. A flashlight and extra batteries are also useful in case you need light after dark, and this small habit can make your trip much ⑤safer.

Consider a large heap containing ten thousand grains of sand. Nearly everyone agrees that removing a single grain from such a heap leaves another heap behind; surely one grain could never make the difference between a heap and a non-heap. Yet if this principle is applied repeatedly, grain by grain, the heap eventually shrinks to a single lonely grain, or even to no grains at all, and logic alone seems to force us to accept that this final result still counts as a heap. Something has clearly gone wrong along the way, since no reasonable person would call one grain of sand a heap, but pinpointing exactly which single removal transformed a heap into a non-heap seems impossible. The puzzle exposes a deep discomfort with vague terms like "heap," "tall," or "bald," concepts that seem to admit no sharp boundary yet are used confidently in everyday language. Some philosophers conclude that _______________.

Team sports place athletes in a uniquely social form of competition, one where individual skill alone rarely determines the outcome of a match. Sports psychologists have long studied why some groups of talented individual players fail to perform as a cohesive unit while other, less individually skilled teams consistently exceed expectations. Trust among teammates appears to be a decisive factor, since _______________. Clear and consistent communication during high-pressure moments further reduces the hesitation and confusion that can unravel a team's coordination in front of a crowd.

주어진 문장: This kind of accuracy might seem convenient at first, but it also raises troubling questions about surveillance. Online advertising algorithms analyze enormous amounts of user data to determine which products a person is most likely to purchase. ( ① ) Every click, search, and pause while scrolling provides information that these systems use to refine future advertisements. ( ② ) As a result, the ads that appear on a person's screen often feel remarkably specific, sometimes referencing items browsed only minutes earlier. ( ③ ) Supporters argue that this level of precision benefits consumers by reducing exposure to irrelevant advertisements and highlighting products they genuinely need. ( ④ ) Critics, however, worry that constant exposure to tailored ads can encourage unnecessary spending, since algorithms are specifically designed to identify and exploit individual weaknesses. ( ⑤ ) Because these algorithms operate largely without public oversight, few consumers fully understand how their personal data shapes what they eventually buy.
