Smartphones, tablets, and computer screens all emit a significant amount of blue light, a short-wavelength light that our eyes are especially ①sensitive to. During the day, exposure to blue light from the sun helps keep us alert and mentally sharp, which is generally beneficial. At night, however, the same wavelength can interfere with the body's natural preparation for sleep. Specialized cells in the retina ②detect blue light and send signals to the brain's internal clock, ③suppressing the release of melatonin, the hormone that signals it is time to rest. Studies have found that ④people who scroll through their phones in bed before sleeping take longer to fall asleep and experience lighter, more easily disrupted sleep than those who avoid screens. Some devices now offer a night mode that shifts the display toward warmer tones, reducing blue light output in the evening. While this feature may help slightly, sleep researchers generally recommend ⑤limit screen use altogether in the hour before bedtime for the best results.

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.

Time blocking is a time-management technique in which a person divides the day into fixed blocks. ___________. Instead of relying on a loose to-do list, the person decides exactly when each task will start and end. This approach lowers the mental effort of deciding what to do next, since the schedule already provides the answer. It also limits multitasking, because each block is reserved for only one activity at a time. For instance, a student may block ninety minutes for math practice, leaving no room for messages or web browsing. Another student may reserve an evening block solely for vocabulary review, treating that time like a fixed appointment. Because each block has a clear boundary, unfinished work is less likely to quietly spread into the next task. Many people who adopt time blocking feel more organized throughout the day.

The planning fallacy describes the tendency to underestimate how long a task will take, even when experience suggests otherwise. Psychologists who studied this bias found that ___________. They focus less on how similar projects actually unfolded before. A student who insists an essay takes two hours, despite needing five hours for every previous essay, shows a clear instance of the fallacy. Large construction projects offer another example. Officials frequently predict completion dates that later prove far too optimistic once delays appear. One reason this bias persists is that people rarely review their history of missed deadlines, relying instead on hopeful imagination. Some researchers recommend a technique called reference class forecasting, comparing a new task to similar completed tasks. By anchoring predictions to real outcomes, planners can produce estimates that are considerably more accurate.

Mira grew up in a small village where fishing and farming had sustained her family for generations. (A) International organizations, however, still struggle to agree on how to protect people like her, since climate migrants are not officially recognized as refugees under current law. (B) Mira missed her old house terribly, yet she slowly began to build a new life in the crowded city, learning to adapt just as her ancestors once had. (C) When the sea finally swallowed the rice paddies that had fed her village for generations, her parents decided that staying was no longer possible. Together with many neighbors, they packed what little they could carry and moved inland, becoming what experts now call climate migrants, people forced to abandon their homes because of rising seas, droughts, or other disasters. This term, rarely used a decade ago, has become increasingly common as extreme weather displaces communities worldwide.

Long before a user finishes typing a sentence, the keyboard on most smartphones has already begun guessing what word comes next. (A) 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. (B) This constant personalization, however, creates a subtle side effect that few users notice, since autocomplete may be quietly narrowing everyday vocabulary. (C) 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, saving users countless keystrokes over the course of a day.

주어진 문장: This constant tracking allows algorithms to build a detailed profile of each user's interests over time. 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. ( ① ) Based on this data, algorithms predict what each individual is most likely to enjoy and quietly prioritize similar content in future results. ( ② ) As a result, two people who type the same search query can receive strikingly different results, each tailored to personal history. ( ③ ) This automatic filtering happens silently, without users ever deciding to limit what they see. ( ④ ) Consequently, many people gradually lose access to viewpoints that challenge their existing beliefs, even though they never intended to avoid them. ( ⑤ ) 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, letting users knowingly escape their own bubbles.

주어진 문장: After all, ignoring proven facts might seem like an irrational thing to do. When people encounter solid scientific evidence about climate change, we might expect them to accept it without hesitation. ( ① ) However, many individuals still dismiss or downplay such evidence, and psychologists explain this pattern through a concept called motivated reasoning. ( ② ) Motivated reasoning refers to the tendency to process information in a way that protects one's existing beliefs, identity, or lifestyle rather than to pursue objective truth. ( ③ ) For example, a person whose livelihood depends on the fossil fuel industry may unconsciously search for reasons to doubt climate data, even while claiming to value scientific accuracy. ( ④ ) This happens because accepting uncomfortable facts can threaten a person's sense of self or demand costly lifestyle changes. ( ⑤ ) Therefore, simply presenting more data rarely persuades a committed skeptic. Instead, experts suggest connecting climate information to values the person already holds, such as family safety or economic stability, so that acceptance feels natural rather than threatening.

주어진 문장: Interestingly, this principle was first observed in government offices, where paperwork seemed to multiply regardless of actual workload. Time-management researchers frequently mention a principle known as Parkinson's Law, which states that work expands to fill the time available for its completion. ( ① ) According to this idea, a task that could be finished in one hour will often stretch to fill an entire afternoon if that much time is scheduled for it. ( ② ) Students who set vague deadlines frequently experience this effect, spending extra hours refining a report that was already complete. ( ③ ) Employees given a full week for a simple project may also delay meaningful progress until the final days, even though the actual work requires far less effort. ( ④ ) This pattern happens partly because people unconsciously adjust their pace to match perceived urgency. ( ⑤ ) Setting shorter, more specific deadlines can counter this tendency, forcing tasks to fit within a tighter and more realistic window. By recognizing how flexible time encourages unnecessary delay, individuals can complete assignments more efficiently without sacrificing quality.

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.
