Time-management researchers frequently mention a principle ①known as Parkinson's Law, which states that work expands to fill the time available for its completion. 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 ②is scheduled for it. Students who set vague deadlines frequently experience this effect, spending extra hours ③refined a report that was already complete. Employees given a full week for a simple project may also delay meaningful progress until the final days, even though the actual work ④requires far less effort. This pattern happens partly because people unconsciously adjust their pace to match perceived urgency. 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 ⑤without sacrificing quality.

Exercise does far more than strengthen muscles and the heart; it also produces ①measurable changes within the brain itself. During sustained physical activity, the body releases a protein called brain-derived neurotrophic factor, which supports the growth of new neurons and ②strengthens connections between existing ones, particularly in regions associated with memory and learning. Studies comparing physically active students to sedentary peers have repeatedly found that the active group performs ③better on tests of attention and problem-solving, even when the exercise session ends well before the test begins. Researchers believe that exercise increases blood flow to the brain, delivering oxygen and nutrients more efficiently, while also ④raising levels of stress hormones that can interfere with clear thinking. Interestingly, aerobic activities such as running or swimming appear to produce more ⑤pronounced cognitive benefits than purely strength-based training.

When people discuss climate change, they often focus only on rising temperatures or melting ice, treating it as a purely scientific issue. However, the concept of climate justice reminds us that the causes and consequences of climate change are distributed ①evenly across the globe. Wealthy, industrialized nations have historically released the ②largest share of greenhouse gases while building their economies, yet developing nations, which contributed comparatively little, frequently suffer the most ③severe droughts and floods. This gap between responsibility and suffering raises a serious ④ethical question that science alone cannot answer. For example, a farming community in a low-income country may lose its entire harvest to an unusual flood, even though its members have never owned a car or flown on a plane. Therefore, tackling climate change requires more than new technology; it demands ⑤fair policies supporting the very communities least responsible for causing the crisis.

Sleep hygiene refers to a set of simple daily habits that help the body prepare for consistent, ①restorative rest. Experts commonly recommend going to bed and waking up at the same time every day, even on weekends, because an irregular schedule ②clarifies the body's internal clock and makes it harder to fall asleep on demand. They also advise reserving the bedroom for sleep alone, since using the bed to study, scroll through a phone, or watch videos teaches the brain to associate that space with ③wakeful activity rather than rest. Physical environment matters as well: a cool, dark, and quiet room tends to produce ④deeper sleep than one that is warm, bright, or noisy. None of these individual habits guarantees a good night's sleep on its own, but together they form a routine that gradually trains the body to expect and enter sleep more easily, much the way a ⑤consistent set of cues trains an athlete's body to perform at a certain time each day.

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.

Across the world, teenagers are chronically short on sleep, often getting two or three hours less than the eight to ten hours experts recommend for their age. Part of the problem lies in biology: as puberty begins, _______________. Yet school start times rarely adjust to this shift, forcing students to wake before their bodies are ready. The consequences extend well beyond simple tiredness. Chronic sleep loss during adolescence has been linked to impaired concentration, weakened memory, and a higher risk of anxiety and depression. It can also disrupt the hormones that regulate appetite, contributing to unhealthy weight gain over time. Some school districts have experimented with delaying start times by even thirty minutes, and early results suggest that students who gain that extra rest show improved grades, better mood, and fewer tardy arrivals. Despite this evidence, changing entrenched school schedules remains a slow and contentious process.

The gap between popular belief and scientific evidence about habit formation has surprised many researchers. (A) This finding suggests that people who quit a new habit after only three weeks may simply be giving up too early, not failing at the habit itself. (B) Their results showed that habits took an average of sixty-six days to become automatic, far longer than the widely repeated twenty-one-day figure. (C) To test how long habit formation truly takes, scientists asked volunteers to track a new daily behavior for several months.

Only a decade ago, translation apps produced sentences so awkward that users often laughed at the results rather than trusting them. (A) Frequent travelers now point their phone cameras at street signs and receive an instant translation overlaid on the screen, thanks to this leap in accuracy. (B) Even so, the technology still struggles with humor, sarcasm, and cultural nuance, areas where a single wrong word can completely change the intended meaning. (C) Today, many of these apps rely on neural networks that analyze entire sentences at once, capturing context instead of translating word by word.

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.

주어진 문장: This growing academic attention reflects how seriously the issue is now being taken. As companies collect enormous amounts of personal data to improve their products and target advertisements, serious ethical questions have emerged about how that information should be handled. ( ① ) Employees who work with big data now face responsibilities that previous generations rarely encountered, since a single careless decision can expose millions of people's private information. ( ② ) Some argue that strict regulations should govern data collection, even if such rules slow innovation and increase costs for businesses. ( ③ ) Others insist that self-regulation within companies, guided by clear ethical training, can protect consumers just as effectively without stifling progress. ( ④ ) Most experts agree that professionals handling sensitive data must be trained not only in technical skills but also in ethical decision-making. ( ⑤ ) Universities have begun adding data ethics courses to computer science programs, recognizing that future employees will need to balance innovation with responsibility.
