Caffeine is the most widely consumed stimulant in the world, ①prizing for its ability to sharpen focus and fight off fatigue within minutes of consumption. It works by blocking adenosine, a chemical that gradually builds up in the brain throughout the day and ②makes us feel increasingly sleepy the longer we stay awake. By occupying the receptors that adenosine would normally bind to, caffeine tricks the brain into ③feeling alert even when the body has accumulated significant sleep pressure. The effects, however, last far longer than most people realize. Because caffeine can remain active in the bloodstream for five to six hours, a cup of coffee ④consumed in the late afternoon may still be interfering with the ability to fall asleep at midnight. Even when people do not consciously notice difficulty falling asleep, caffeine has been shown ⑤to reduce the amount of deep, restorative sleep obtained later in the night.

Opening most camera apps today reveals a row of filters that can smooth skin, brighten eyes, and reshape a jawline before a photo is even taken, all powered by AI models trained to recognize facial features in real time. What began as a playful novelty has become a ①default setting for many users, subtly adjusting nearly every selfie posted online. Psychologists have grown concerned about a specific consequence of this shift: people increasingly compare their unfiltered reflection in a mirror to a filtered version of themselves seen constantly on a screen, a comparison that earlier generations never had to ②face. Some social media platforms have responded by ③labeling heavily edited photos or banning certain filters that alter body shape. Whether such small warnings can meaningfully ④worsen the daily flood of filtered images, however, remains an ⑤open question that researchers are only beginning to study.

As artificial intelligence grows more capable of performing tasks once considered exclusively human, many people wonder which skills will remain valuable in the future. AI can now analyze data, generate text, and even diagnose certain medical conditions with ①impressive accuracy. However, most researchers argue that AI still ②struggles with tasks requiring genuine empathy, ethical judgment, and creative problem-solving in unfamiliar situations. A machine can recommend a treatment plan based on statistics, for instance, but it can ③easily comfort a frightened patient the way a compassionate nurse can. Similarly, AI can generate countless design variations, yet it ④lacks the lived experience that allows humans to judge which idea truly resonates with people. For this reason, educators increasingly emphasize skills such as collaboration and emotional intelligence, arguing that these human capabilities will become more ⑤valuable as automation spreads.

Behavioral economists use the term status quo bias to describe a tendency to prefer the ①present situation over a new alternative, even when the alternative would bring greater benefits. This bias helps explain why many households ②rush to switch to renewable energy, such as installing solar panels on their roofs. Although solar panels can lower electricity bills over time, homeowners often stick with their current power source because it feels ③safe and requires no immediate effort. In contrast, switching demands research, upfront cost, and trust in unfamiliar technology, all of which can seem ④risky compared with doing nothing. For example, a neighborhood association might repeatedly ⑤postpone a vote on shared solar panels, not because the plan is flawed, but because members are reluctant to leave their routine. Therefore, boosting renewable adoption may depend less on proving its advantages and more on designing programs that make the first step feel easy.

Advertisements often rely on subtle psychological techniques that persuade viewers without their conscious awareness. One common method, known as social proof, shows images of many people using or enjoying a product, suggesting that its popularity guarantees quality. Another technique appeals to authority, featuring experts or professionals endorsing a product to make it seem more credible and trustworthy. Emotional appeals are equally common, connecting products with feelings such as happiness, nostalgia, or belonging rather than focusing on practical features. Repetition also plays a significant role, since seeing the same advertisement multiple times increases familiarity, which people often mistake for reliability. Researchers studying consumer behavior have found that ___________, since awareness disrupts the automatic psychological response advertisers depend on.

Three-dimensional printing technology is changing how products are designed and manufactured across many industries. Unlike traditional manufacturing, which often requires expensive molds and long production times, ___________. This flexibility allows companies to produce small batches of customized products without the massive costs typically associated with mass production.

Remote work has moved from a rare privilege to a common practice for millions of employees worldwide. Supporters argue that remote work increases productivity, since employees avoid long commutes and distracting office environments. It also allows companies to hire talented people regardless of where they live, widening the pool of candidates. Critics, however, worry that remote work weakens teamwork and makes it harder for new employees to learn from experienced colleagues. Without regular face-to-face interaction, some workers feel isolated and struggle to build strong professional relationships. For these reasons, many experts suggest that the future of work will likely be ___________, combining flexibility with occasional in-person collaboration.

A growing number of health apps now track steps, sleep, and heart rate throughout the day, quietly building a detailed picture of a user's physical condition without requiring a single visit to a doctor's office. (A) Doctors caution, however, that these apps are designed to detect patterns, not to diagnose illness, and that a worried user should always confirm any alarming reading with a professional. (B) For people living far from specialists or unable to afford frequent checkups, this kind of constant monitoring can feel like a genuine safety net. (C) By comparing this stream of data against patterns drawn from millions of other users, the app's algorithm can flag early warning signs, such as an irregular heartbeat, long before the person notices anything unusual.

주어진 문장: Not everyone, however, feels this financial burden equally, since household circumstances vary widely. The term green premium describes the extra cost that consumers must pay when they choose an environmentally friendly product or energy source over a conventional, cheaper alternative. ( ① ) For example, an electric vehicle or solar-powered appliance often carries a higher price tag than its gasoline-powered or coal-based counterpart, even though it produces fewer emissions over time. ( ② ) This price gap frequently discourages shoppers who support sustainability in principle but cannot justify the additional expense within a limited household budget. ( ③ ) In contrast, wealthier consumers can absorb the premium more easily, which creates unequal participation in green markets. ( ④ ) To narrow this gap, governments have introduced subsidies and tax credits that lower upfront costs, while companies invest in research to make clean technologies cheaper to manufacture. ( ⑤ ) As production scales up and innovation continues, many economists expect the green premium to shrink steadily, eventually making sustainable choices the more affordable option for most consumers.

주어진 문장: In other words, the default option is far more powerful than most people realize. 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. ( ① ) Research consistently shows that people tend to stick with whatever is already set, even when changing it takes only seconds. ( ② ) 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. ( ③ ) 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. ( ④ ) Critics argue that default options can be manipulated to benefit companies rather than individuals, so transparency about how defaults are chosen becomes essential. ( ⑤ ) Still, supporters insist that because some default must always exist, it should support people's own long-term interests rather than mere institutional convenience.
