Sociologist Mark Granovetter introduced an idea that seems ①contradictory at first glance, known as the strength of weak ties. According to this theory, people who see each other only ②occasionally, called weak ties, often provide more valuable information than close friends or family members, who are considered strong ties. This happens because strong ties tend to share the same social circles and, therefore, already possess ③similar knowledge. Weak ties, in contrast, move within different networks, which allows them to introduce ideas or opportunities that would otherwise remain unknown. For example, a former classmate rarely contacted might mention a job opening unavailable through one's immediate circle. Social media platforms have made maintaining such connections remarkably ④harder, letting users keep hundreds of loose acquaintances active without frequent face-to-face meetings. Consequently, these platforms function as efficient channels through which weak ties continue delivering ⑤fresh opportunities that close relationships simply cannot offer.

Every day, email providers quietly block billions of ①unwanted messages before they ever reach a user's inbox, a task that would be impossible without an AI filtering system running constantly in the background. The filter ②examines each incoming message for suspicious patterns, including certain keywords, unusual sender addresses, and formatting tricks that scammers commonly rely on to slip past detection. What makes the system effective is that it ③stops learning after launch, since whenever a user marks a message as spam or rescues a message mistakenly filtered out, that action becomes new training data, sharpening the filter's future decisions. This creates a constant back-and-forth, since spammers study which messages get blocked and then ④adjust their wording to slip through again. As a result, spam filtering is less like a fixed wall and more like an ⑤ongoing contest, with each side continuously adapting to outsmart the other.

Limited-edition products are goods that are released in small quantities for a short period of time. Many companies use this strategy because ___________. When consumers believe that a product will disappear soon, they often feel pressured to buy it immediately rather than wait. For instance, a sneaker company that releases only a few thousand pairs of a special design can generate long lines outside stores overnight. This excitement is intensified by social media, where people proudly share photos of items that others could not obtain. However, this psychological pressure can lead to purchases that are driven by fear rather than genuine need. As a result, some shoppers later regret spending money on products they rarely use afterward.

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.

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.

Aerobic exercise, such as jogging, swimming, or cycling at a steady pace, produces a wide range of benefits that extend well beyond simple calorie burning. (A) This adaptation explains why trained athletes often have a much lower resting heart rate than sedentary individuals of the same age. (B) Over weeks of consistent training, the heart gradually enlarges and becomes more efficient, delivering the same amount of oxygen to working muscles while beating fewer times per minute. (C) Most fundamentally, it strengthens the heart itself, forcing it to pump larger volumes of blood with each beat.

Many self-help books emphasize the cue-routine-reward loop as a tool for building better habits. (A) For example, athletes who want to build a stretching habit often rely on a specific cue, such as arriving at the gym, to trigger the same short routine every time. (B) Over time, this consistent pairing strengthens the neural pathway connecting the cue to the routine, making the behavior feel almost automatic. (C) According to this model, every habit consists of three connected parts: a cue that triggers behavior, a routine that follows, and a reward that reinforces it.

Feed an AI music program a mood, a tempo, and a rough genre, and within seconds it can generate a complete instrumental track. (A) The software has studied thousands of existing songs, learning which chord progressions and rhythms tend to sound pleasant together, and it recombines these patterns into something new. (B) For independent creators who cannot afford a composer or expensive licensing fees, this has been a genuine breakthrough. (C) Professional musicians, however, remain divided, since a flood of AI-generated background music could quietly push human composers out of smaller, lower-budget projects.

As the metaverse develops, entirely new categories of professional work are emerging alongside it. (A) Virtual event planners, for instance, now organize concerts and conferences that take place entirely within digital platforms. (B) Some skepticism remains, since the technology has not yet attracted the enormous user base that early predictions promised. (C) Despite this uncertainty, major companies continue to invest heavily, betting that virtual spaces will eventually rival physical venues in importance.

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.
