Drinking enough water ①are especially important during the hot summer months. When you sweat a lot, your body loses not only water but also important minerals ②called electrolytes. If you do not replace these losses, you may feel tired, dizzy, or ③even suffer from muscle cramps. It is best ④to avoid sugary drinks and too much caffeine, since they can make dehydration worse. Eating water-rich fruits and vegetables ⑤can also help you stay hydrated.

A printer that once produced only plastic prototypes can now ①deposit living cells layer by layer to build a structure that begins to resemble actual tissue. Bioprinting adapts the logic of conventional 3D printing, ②replacing plastic filament with a specialized ink made of living cells suspended in a gel that supports their survival while the shape sets. Printing a flat patch of skin or a simple blood vessel has already moved from laboratory curiosity to early clinical testing, since these tissues ③is thin enough for nutrients to reach every cell by diffusion. Printing a solid organ such as a kidney remains a far greater challenge, because internal cells starve without their own blood supply, and no printer yet exists that can build a network of vessels fast enough ④to keep them alive. Researchers are therefore focusing on hybrid strategies, printing a rough scaffold and then ⑤allowing the tissue to mature and grow its own vasculature over time.

Planning a multi-city trip once meant hours spent comparing flight schedules, reading hotel reviews, and mapping out which sights were close enough to visit in a single day. AI travel planners now ①compress much of that work into a short conversation, asking about a budget, a travel style, and a handful of preferences before generating a full day-by-day itinerary within minutes. The tool draws on enormous amounts of data to suggest a route that avoids obvious ②scheduling conflicts. Many travelers appreciate having a solid starting point rather than a ③blank page. Still, seasoned travelers warn that these itineraries can feel oddly ④unique, often steering users toward the same popular landmarks that every other AI-generated plan recommends, while ⑤overlooking smaller, lesser-known places that a knowledgeable local guide might have suggested instead.

Team sports place athletes in a uniquely social form of competition, one where individual skill alone ①rarely 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 ②exceed expectations. Trust among teammates appears to be a ③decisive factor, since players who believe their teammates will reliably fulfill their roles are more willing to take the calculated risks that winning often requires. Clear and consistent communication during high-pressure moments further reduces the hesitation and confusion that can ④unravel a team's coordination in front of a crowd. Interestingly, researchers have found that teams which deliberately build informal social bonds off the field tend to display better on-field cohesion, suggesting that chemistry can ⑤easily be manufactured through drills alone.

The science club at Hanul High School is running a project called "Grow Light." It tests how different colors of light affect plant growth. Each week, members place identical bean sprouts under red, blue, and white light and record their height. At first, many students expected the white light to produce the tallest plants. However, _______________________. The club's advisor explained this by comparing light to food. Just as people need certain nutrients to grow strong, plants absorb certain colors of light more efficiently than others. To make the data reliable, students repeat each trial three times and calculate the average. They also keep a shared notebook, recording sunlight, watering time, and temperature. Next month, the club plans to present these findings at the school science fair.

Internet activist Eli Pariser introduced the term filter bubble to describe a phenomenon created by online algorithms. Social media platforms and search engines constantly track which links users click and how long they linger on certain posts. Based on this data, algorithms predict what each individual is most likely to enjoy and quietly prioritize similar content in future results. As a result, two people who type the same search query can receive strikingly different results, each tailored to personal history. This automatic filtering happens silently, without users ever deciding to limit what they see. Consequently, many people gradually lose access to viewpoints that challenge their existing beliefs, even though they never intended to avoid them. Pariser warned that this invisible curation could weaken democratic debate by narrowing public discussion. Therefore, some experts argue that platforms should reveal how content is filtered, _______________.

City governments increasingly market dense networks of surveillance cameras as a straightforward safety upgrade, promising faster emergency response and lower crime rates. (A) Yet the same infrastructure that catches criminals also creates a permanent record of where ordinary, law-abiding citizens go about their daily lives. (B) In many cases, the technology delivers exactly what it promises, helping investigators identify suspects within hours rather than weeks. (C) Once a camera network exists, its purpose can quietly expand, from tracking traffic accidents to monitoring political protests, often without new public debate.

The eventual collapse of a speculative bubble often unfolds with surprising speed compared with the gradual climb that preceded it. (A) As prices begin to fall, investors who bought near the peak, motivated largely by fear of missing further gains, are often the first to sell, since they have the least conviction in the asset's underlying value. (B) Their selling triggers further price declines, which in turn prompt additional investors to sell out of a newly urgent fear of continued loss rather than a fear of missing out. (C) This reversal illustrates that the same herd psychology driving prices upward can just as easily reverse direction, converting collective optimism into collective panic within a remarkably short period.

Coaches have traditionally focused athlete preparation on training volume and nutrition, but a growing body of research suggests that sleep deserves equal attention. (A) In response, many professional teams now employ sleep specialists who design travel schedules, control bedroom lighting and temperature, and even adjust competition start times when possible. (B) Frequent travel across time zones compounds this challenge considerably, since jet lag can disrupt an athlete's natural sleep-wake cycle for several days after a long flight. (C) During deep sleep, the body releases growth hormone, essential for repairing muscle tissue, while the brain consolidates motor skills practiced earlier that day into more stable, efficient patterns.

Treating a wellness app as a substitute for medical expertise, they warn, can be just as risky as ignoring a warning altogether. A growing number of health apps now track steps, sleep, and heart rate throughout the day, quietly building a detailed picture of a user's physical condition without requiring a single visit to a doctor's office. ( ① ) 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 experiencing it would have noticed anything unusual on their own. ( ② ) For people living far from specialists or unable to afford frequent checkups, this kind of constant monitoring can feel like a genuine safety net. ( ③ ) Doctors caution, however, that these apps are designed to detect patterns, not to diagnose illness. ( ④ ) A worried user should always confirm any alarming reading with a professional rather than trusting an app's suggestion alone. ( ⑤ )
