Caffeine is the most widely consumed stimulant in the world, ①prizing for its ability to sharpen focus and fight off fatigue within minutes of consumption. It works by blocking adenosine, a chemical that gradually builds up in the brain throughout the day and ②makes us feel increasingly sleepy the longer we stay awake. By occupying the receptors that adenosine would normally bind to, caffeine tricks the brain into ③feeling alert even when the body has accumulated significant sleep pressure. The effects, however, last far longer than most people realize. Because caffeine can remain active in the bloodstream for five to six hours, a cup of coffee ④consumed in the late afternoon may still be interfering with the ability to fall asleep at midnight. Even when people do not consciously notice difficulty falling asleep, caffeine has been shown ⑤to reduce the amount of deep, restorative sleep obtained later in the night.

Turning on automatic captions used to mean settling for garbled text full of obvious errors, but recent speech-recognition models have made same-language captions ①accurate enough that many viewers now leave them on by default, even when watching content in their native language. The technology listens to audio, breaks it into individual sounds, and matches those sounds against a massive library of words and phrases ②to predict what was actually said. For viewers who are deaf or hard of hearing, this improvement has quietly ③transformed everyday access to video content that once required a human transcriber. The system still stumbles over overlapping speakers, strong accents, and specialized vocabulary, ④occasionally producing captions that are unintentionally funny. Even with these flaws, most users agree that imperfect captions ⑤is far more useful than no captions at all.

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. These tools check grammar and spelling, of course, but the more advanced versions go further, suggesting clearer phrasing, ①flagging repetitive words, and even adjusting tone to sound more formal or more casual depending on the purpose. Teachers generally ②welcome the grammar and spelling support, since it frees up class time to focus on argument and structure rather than comma placement. Concerns ③shrink, however, around the tone and phrasing suggestions, which can gradually nudge every student's writing toward a similar, polished style, making it harder to tell an individual voice from a suggestion generated by the same underlying model. Some schools have begun asking students to submit an early draft alongside the final version, specifically to ④preserve evidence of a student's own ⑤original voice.

Only a decade ago, translation apps produced sentences so awkward that users often laughed at the results. 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 smooth. Even so, the technology still struggles with humor, sarcasm, and cultural nuance, so that _______________. For this reason, professional translators argue that these apps are best treated as a helpful starting point rather than a final, polished result.

Anthropologist Robin Dunbar proposed a concept now known as Dunbar's number, suggesting that human beings can only maintain about one hundred fifty stable social relationships at any given time. This limit, he argued, comes from the size of the human brain, which restricts how many meaningful connections a person can cognitively manage. In contrast, many social media users today have hundreds or even thousands of online friends and followers, a number far exceeding what Dunbar's research predicts. However, having numerous digital contacts does not necessarily mean that all of these relationships are close or emotionally supportive. Most users, when asked, admit that they interact regularly with only a small fraction of their total followers, while the rest remain largely unnoticed. Therefore, Dunbar's number reminds us that ___________.

Imagine two factories making the same product: one in a country with strict carbon rules, and one in a country with almost none. The factory facing stricter rules often spends more, which can make its goods pricier than those made elsewhere. To fix this imbalance, some governments have introduced the carbon border adjustment mechanism, a policy charging imported goods a fee based on how much carbon was released while producing them. Supporters argue that the system _______________. However, critics claim it unfairly burdens developing countries, which often lack money to modernize factories quickly. For example, a small exporter in a poorer nation might struggle to pay the added charge, though it contributes little to global emissions. Still, if wealthier nations pair the policy with technical support, it could become a genuinely fair tool for cutting emissions worldwide.

주어진 문장: Because the timer makes each interval visible and concrete, students often feel a stronger sense of urgency during each session. Among strategies for improving concentration, the Pomodoro Technique remains one of the most widely recommended methods for students and workers. ( ① ) This technique involves working with full attention for twenty-five minutes, then taking a short five-minute break before starting the next session. ( ② ) After completing four of these cycles, a longer break of fifteen to thirty minutes is usually taken to allow mental recovery. ( ③ ) The method assumes that sustained focus becomes harder to maintain as time passes, so frequent short breaks prevent mental fatigue from building up. ( ④ ) Students preparing for exams report finishing reading assignments faster when they follow this structured rhythm instead of studying without interruption. Office workers find that dividing large projects into short, timed intervals makes overwhelming tasks feel more manageable. ( ⑤ ) Because each interval has a clear start and end, procrastination becomes less tempting, since beginning a single twenty-five-minute session requires less commitment than beginning an entire project.

Shoppers use it to find where an item seen on the street can be purchased, while students use it to identify plants, insects, or historical artworks in seconds. Instead of typing keywords into a search bar, a growing number of people now simply upload a photo and let an algorithm figure out what it contains. ( ① ) This process, known as reverse image search, compares the visual patterns in a picture against a massive database, identifying everything from a landmark in the background to the exact model of a pair of sneakers. ( ② ) The system works by breaking an image down into countless small features, such as edges, colors, and shapes, then matching that pattern against millions of stored examples. ( ③ ) It is not flawless, however. ( ④ ) A blurry photo, an unusual camera angle, or an object partly hidden behind another can easily confuse the algorithm, leading to search results that have nothing to do with the original picture at all. ( ⑤ )

주어진 문장: This heightened sensitivity can manifest in a variety of noticeable ways. In recent years, mental health experts have identified a distinct emotional response to environmental crisis, commonly called eco-anxiety. ( ① ) Eco-anxiety describes persistent worry, grief, or fear triggered by awareness of climate change and its consequences for the future. ( ② ) Although people of all ages can experience it, teenagers and young adults seem especially vulnerable, since they anticipate living through decades of worsening conditions. ( ③ ) Common symptoms include difficulty sleeping, a sense of hopelessness, and guilt over ordinary choices such as travel or diet. ( ④ ) For example, some students report feeling paralyzed whenever they read alarming climate news, unable to focus on schoolwork or hobbies. ( ⑤ ) However, experts emphasize that eco-anxiety is not a disorder to be eliminated but a natural reaction that can be channeled productively. Rather than avoiding the topic, young people are encouraged to join community projects, since taking constructive action tends to restore a sense of control and ease overwhelming distress.

주어진 문장: In contrast, downward comparison, which involves comparing oneself with someone worse off, can temporarily boost self-esteem instead. Psychologist Leon Festinger introduced social comparison theory, which explains that people evaluate their own abilities and opinions by comparing themselves with others. ( ① ) According to this theory, individuals engage in upward comparison when they measure themselves against someone who appears more successful, attractive, or accomplished. ( ② ) Social media platforms, filled with carefully edited photos and exaggerated achievements, provide endless opportunities for this kind of comparison. ( ③ ) For instance, a teenager browsing vacation pictures posted by classmates may begin to feel that her own ordinary life is somehow inadequate. ( ④ ) Unlike comparing oneself with someone in a similar position, which can sometimes boost confidence, upward comparison frequently triggers envy, dissatisfaction, and lower self-esteem. ( ⑤ ) Researchers have found that frequent upward comparison online is linked to higher depression and anxiety. Consequently, this theory helps explain why scrolling through social media often leaves users feeling worse rather than better about themselves.
