Internet activist Eli Pariser introduced the term filter bubble to describe a phenomenon ①created by online algorithms. Social media platforms and search engines constantly track which links users click and how long they linger on certain posts. Based on this data, algorithms predict what each individual is most likely ②to enjoy and quietly prioritize similar content in future results. As a result, two people who type the same search query can receive strikingly different results, each ③tailoring to personal history. This automatic filtering happens silently, without users ever ④deciding to limit what they see. Consequently, many people gradually lose access to viewpoints ⑤that challenge their existing beliefs, even though they never intended to avoid them.

Many people feel a sudden wave of anxiety when their smartphone battery is nearly dead or they have ①left it at home. This intense discomfort, known as nomophobia, is short for "no-mobile-phone phobia," a term ②describing the fear of losing connection to one's phone. Researchers explain that this fear develops because smartphones have become tightly linked to social belonging; missing a notification can feel like ③be cut off from friends. For example, some students check their phones dozens of times an hour, even during class, just to confirm nothing important ④has been missed. Recognizing nomophobia as a real psychological pattern ⑤is the first step toward a healthier relationship with technology.

Only a decade ago, translation apps produced sentences so awkward that users often laughed at the results rather than trusting them. Today, many of these apps rely on neural networks ① 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. Frequent travelers now point their phone cameras at street signs and ② receiving an instant translation overlaid on the screen. Even so, the technology still struggles with humor, sarcasm, and cultural nuance, areas ③ where a single wrong word can completely change the intended meaning. A joke that depends on wordplay in one language may become confusing once it ④ is translated literally into another. For this reason, professional translators argue that these apps are best treated as a helpful starting point rather than a final, polished result that no human ⑤ needs to review.

Choice architecture refers to how decisions are designed. It determines which option is automatically selected unless a person chooses otherwise, known as the default option. Research consistently shows that ___________, even when changing it takes only seconds. Organ donation is a well-known example. Countries where citizens are automatically registered as donors unless they opt out show much higher donation rates than opt-in countries. Retirement savings programs show a similar pattern, since employees automatically enrolled in a pension plan rarely cancel it. Voluntary sign-ups, in contrast, often delay indefinitely. Critics argue that default options can be manipulated to benefit companies rather than individuals, so transparency about how defaults are chosen becomes essential. Still, supporters insist that because some default must always exist, it should support people's own long-term interests rather than mere institutional convenience.

When Mina was a freshman, she often spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study in which children could eat one marshmallow immediately or wait for two. Researchers found that children who waited longer showed better academic performance and self-control years later. This ___________ is known as delayed gratification. Inspired by the study, Mina began saving half of her allowance each week instead of spending it all on snacks.

In the days leading up to an endurance event, many athletes deliberately increase their carbohydrate intake while reducing training volume, a practice known as carbohydrate loading. The strategy is designed to maximize the amount of glycogen, the storage form of carbohydrate, packed into muscle tissue before competition begins. Because glycogen serves as the primary fuel source during prolonged, intense exercise, _______________. Sports nutritionists caution, however, that the timing and composition of meals matter as much as the total quantity of carbohydrate consumed, since eating unfamiliar foods immediately before competition can cause digestive discomfort.

FOMO refers to the anxious feeling that arises when people believe they are missing out on rewarding experiences that others are having. (A) For instance, a student who sees photos of a gathering she missed may feel sudden regret, even though the event is already over. (B) This feeling often leads people to check their phones compulsively, which makes it hard to focus on tasks at hand. (C) Such experiences are common among heavy social media users, who constantly compare their lives with the curated posts of others.

주어진 문장: This pattern echoes what happened during previous waves of industrial automation. Self-driving technology is advancing rapidly, and its impact on the transportation industry is becoming increasingly visible. ( ① ) Companies are testing autonomous trucks that can travel long distances without human drivers, potentially transforming how goods move across countries. ( ② ) At the same time, millions of professional drivers worry about losing their jobs as automation spreads through the industry. ( ③ ) Experts predict that certain driving jobs, particularly long-distance trucking, may shrink significantly within the next two decades. However, new roles are also emerging, including remote vehicle operators and technicians who maintain the complex sensors these vehicles depend on. ( ④ ) Workers who adapt their skills toward supervising and maintaining these systems are likely to find new opportunities rather than face unemployment. ( ⑤ )

주어진 문장: In other words, the promised environmental benefit is far less certain than it first appears. To compensate for their carbon emissions, many individuals and companies now purchase carbon offsets, financial credits that fund projects such as planting trees or building renewable energy plants. ( ① ) The idea is appealing: paying for an equivalent amount of carbon to be absorbed elsewhere should cancel out the harm caused by activities like flying. ( ② ) However, critics argue that this system often functions as a convenient excuse for postponing genuine emission cuts rather than achieving them. ( ③ ) For example, a newly planted forest may take decades to absorb the promised carbon, and it could later burn down or be cut, erasing any benefit. ( ④ ) Moreover, some offset projects would have happened anyway, meaning the credits fund nothing truly additional. ( ⑤ ) Therefore, relying heavily on offsets allows businesses to maintain harmful practices while appearing responsible. Experts insist that offsetting should complement, not replace, direct reductions in fossil fuel use if the strategy is to remain credible.

This process, though it may sound simple, triggers a remarkable series of adaptations throughout the cardiovascular system. Aerobic exercise, such as jogging, swimming, or cycling at a steady pace, strengthens the heart by forcing it to pump larger volumes of blood with each beat. ( ① ) Over weeks of consistent training, the heart gradually enlarges and becomes more efficient, meaning it can deliver the same amount of oxygen to working muscles while beating fewer times per minute. ( ② ) This adaptation explains why trained athletes often have a much lower resting heart rate than sedentary individuals of the same age. ( ③ ) Beyond the heart itself, aerobic activity encourages the body to build new capillaries within muscle tissue, improving the delivery of oxygen and nutrients at a cellular level. ( ④ ) Researchers have also found that regular aerobic exercise reduces inflammation throughout the body and improves the way cells respond to insulin. ( ⑤ )
