When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers belonged only to a handful of government scientists. By the time he entered university, however, the space industry had changed ①dramatically, as private companies began launching satellites and building reusable rockets. Daniel studied aerospace engineering, drawn to the idea that space exploration was no longer ②limited to a few national agencies. During an internship, he helped design a small satellite intended to ③monitor crop health from orbit. He realized that the space industry now needed not only pilots and engineers but also data analysts, technicians, and even lawyers familiar with international space regulations. After graduation, Daniel joined a startup developing lunar landing equipment, a job that ④barely existed when he first imagined his future career. His story shows how commercial space ventures have ⑤closed doors that once seemed impossibly narrow.

The twenty-hour rule proposes that years of practice are not needed to become skilled at a new activity. Only about twenty hours of effort are needed to reach a ①worthless level. Unlike theories claiming true mastery requires ten thousand hours, this rule targets a more ②modest goal. That goal is simple competence for everyday use. According to supporters, practicing any new skill produces the ③fastest visible improvement, since a beginner has room to grow. Advocates emphasize that the twenty hours must be ④deliberate and focused, broken into short daily sessions rather than one long stretch. The hours should be aimed at fixing weaknesses rather than ⑤repeating what one already knows.

Behavioral economists use the term temporal discounting to describe how people ①undervalue future rewards simply because those rewards are not immediate. This tendency explains why a student might choose to watch videos tonight rather than study for an exam that remains several weeks away, even though studying offers a ②smaller long-term benefit. A distant reward, no matter how valuable, feels psychologically smaller than a small reward available right now. This bias contributes to procrastination, since future consequences rarely feel ③urgent enough to motivate immediate action. To counter this tendency, students should ④convert distant goals into smaller, near-term milestones that feel more emotionally real. Setting weekly checkpoints rather than a final deadline can make future benefits feel ⑤closer and more concrete.

A smart thermostat that learns a family's daily rhythm can lower the temperature automatically before everyone wakes up cold, while smart lights that follow a resident's schedule no longer need to be switched on and off by hand. (A) These small conveniences rest on a shared foundation: sensors collect data about temperature, motion, and light throughout the home, and an algorithm gradually learns which settings match each household's actual habits. (B) Over months of use, the system becomes noticeably better at anticipating needs, often adjusting settings moments before a resident would have reached for a switch. (C) Yet convenience comes with a trade-off that many households overlook, since a detailed record of daily habits is quietly being stored somewhere beyond their immediate control.

Imagine two factories making the same product: one in a country with strict carbon rules, and one in a country with almost none. (A) 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. (B) Supporters argue that the system protects domestic industries and pushes foreign manufacturers toward cleaner methods. (C) 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.

주어진 문장: Even a short break from checking their phones can trigger a nagging sense of unease. Many teenagers check their social media accounts dozens of times a day, worried that they might miss something important happening among their friends. ( ① ) This anxiety, known as FOMO, or the fear of missing out, arises when people believe that others are enjoying experiences from which they themselves are excluded. ( ② ) For example, a student scrolling through photos of a party she was not invited to may suddenly feel a wave of loneliness and regret, even though the event has already ended. ( ③ ) Constantly refreshing feeds to avoid missing such updates, however, makes it difficult to concentrate on schoolwork or conversations happening in the present moment. ( ④ ) Moreover, this endless comparison with curated highlights of other people's lives tends to deepen feelings of anxiety rather than relieve them. ( ⑤ ) Therefore, students should learn to limit their social media use and focus more attention on the relationships and activities directly in front of them.

주어진 문장: That plan, however, took an unexpected turn during his final year of university. Jiho had always assumed he would join a large corporation after graduation, just as his parents expected. ( ① ) He joined a small student team building an app that connected local farmers directly with restaurants. ( ② ) What started as a class project gradually turned into something more serious, as several restaurants began placing regular orders through their prototype. ( ③ ) Jiho and his teammates decided to delay job applications and instead spend a year developing the idea, despite warnings from relatives who considered the plan too risky. ( ④ ) They worked from a cramped apartment, surviving on limited savings while learning skills ranging from coding to negotiating with suppliers. ( ⑤ ) After nearly failing twice, the team secured a small investment that allowed them to hire their first employee.

주어진 문장: Because the number of likes a post will receive is never guaranteed, every notification carries a small element of suspense. Psychologists have long studied a mechanism called the variable reward schedule, in which rewards arrive unpredictably rather than after every single action. ( ① ) Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. ( ② ) When someone posts a photo, they cannot predict exactly when likes will appear, nor how many they will eventually receive. ( ③ ) This uncertainty triggers a small burst of dopamine each time the phone is checked, regardless of whether the result is disappointing or thrilling. ( ④ ) Consequently, users often refresh their feeds compulsively, hoping the next check will finally bring a satisfying reward. ( ⑤ ) What makes this troubling is that technology companies deliberately designed notification systems using insights borrowed from gambling research, rather than stumbling upon them by accident. Such practices raise serious ethical questions about manipulating users' brains for profit. Therefore, people must consciously recognize this hidden mechanism and set firm limits on their checking habits.

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

주어진 문장: Creating a convincing avatar, in other words, is far more complex than simply choosing a picture. The metaverse, a network of interconnected virtual worlds, has begun to generate job opportunities that did not exist just a few years ago. ( ① ) Companies now hire virtual world designers who build digital environments where users can socialize, shop, or attend events. Avatar designers create digital identities that represent users within these spaces, blending artistic skill with technical programming knowledge. ( ② ) Meanwhile, virtual event planners organize concerts, conferences, and product launches entirely within online platforms, reaching audiences that would be impossible to gather in person. ( ③ ) Some analysts remain skeptical, pointing out that the metaverse has not yet attracted the massive user base that early predictions promised. ( ④ ) Nevertheless, major companies continue investing heavily in this technology. ( ⑤ ) For students considering future careers, gaining skills in three-dimensional design and coding may prove valuable.
