When a customer opens a company's website at midnight with a billing question, an actual employee is unlikely ①to be available, which is exactly the gap that customer service chatbots were built ②to fill. These programs can instantly answer common questions, track packages, and process simple refunds without ③making anyone wait on hold. Yet the technology has clear boundaries. When a customer's problem is unusual, emotionally charged, or simply does not fit the chatbot's script, the automated replies can feel frustratingly circular, ④repeating the same suggestion no matter how the question is rephrased. Many companies have responded by designing chatbots to recognize their own limits, automatically ⑤transfer a frustrated customer to a human agent before the conversation turns into a source of complaint rather than a solution.

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.

Many companies today advertise their products as environmentally friendly, yet not all of these claims are accurate. This practice, ①knowing as greenwashing, involves exaggerating or fabricating a product's positive impact on the environment. Consumers, ②who are increasingly concerned about climate change, often trust such claims without questioning them closely. As a result, they may pay higher prices for products ③that are no more sustainable than ordinary alternatives. Genuine environmental efforts, which usually ④require significant investment and long-term planning, are far more costly than simply changing a label. Therefore, governments should establish clear standards ⑤that require companies to prove their environmental claims with verifiable data.

When a price is crossed out and replaced with a lower number, consumers instinctively perceive the new price as a ①loss, even if the original price was rarely charged. Limited-time sales further ②intensify this effect, since a ticking clock encourages rushed decisions that leave little room for careful comparison. Retailers also use phrases such as "while supplies last" to suggest ③scarcity, even when inventory remains plentiful. Over time, frequent sales can actually train customers to wait for discounts rather than buy at full price, which can ④hurt long-term profits. Despite this risk, many companies continue relying on sales events because the short-term boost in customer traffic usually ⑤outweighs the potential downside.

Many people feel a ①sudden wave of anxiety when their smartphone battery is nearly dead or they have left it at home. This ②intense discomfort, known as nomophobia, is short for "no-mobile-phone phobia." Researchers explain that this fear develops because smartphones have become ③tightly linked to social belonging; missing a notification can feel like being cut off from friends. Therefore, experts suggest gradually reducing phone checks to ④strengthen this anxious dependence. Recognizing nomophobia as a real psychological pattern is the first step toward a ⑤healthier relationship with technology.

When a beverage company launched a new flavor last summer, the marketing team faced a tight budget and needed a creative solution. Instead of relying on expensive television commercials, they designed a simple dance challenge and invited a handful of everyday users to post videos using the product. Within days, thousands of people began recreating the dance and tagging the brand, turning an ordinary product launch into a viral trend. The company barely spent any money on production, yet the challenge reached millions of viewers across multiple platforms. Encouraged by this success, other brands quickly attempted similar challenges, though many failed to generate the same excitement. Researchers later explained that the original challenge succeeded because it felt spontaneous and fun rather than obviously commercial. This case demonstrates that ___________.

Feed an AI music program a mood, a tempo, and a rough genre, and within seconds it can generate a complete instrumental track. 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. For independent creators who cannot afford a composer, this has been a genuine breakthrough. Professional musicians, however, remain divided. Some welcome the tool as a quick way to sketch ideas before refining them by hand, while others worry that _______________.

Mira had lived in a coastal village since birth, watching the tide creep closer to her family's doorstep every year. When the sea finally swallowed the rice paddies that had fed her village for generations, her parents decided that staying was no longer possible. Together with many neighbors, they packed what little they could carry and moved inland, becoming what experts now call climate migrants, _______________. This term, rarely used a decade ago, has become increasingly common as extreme weather displaces communities worldwide. Mira missed her old house terribly, yet she slowly began to build a new life in the crowded city, learning to adapt just as her ancestors once had. International organizations, however, still struggle to agree on how to protect people like her, since climate migrants are not officially recognized as refugees under current law.

Sleep is not a single, uniform state but a cycle that alternates between two very different modes: REM (rapid eye movement) sleep and non-REM sleep. During non-REM sleep, especially its deepest stage, the brain waves slow down dramatically, the body temperature drops, and tissue repair and growth hormone release reach their peak. This is the period most closely associated with physical restoration. REM sleep, by contrast, brings rapid eye movements, near-total muscle paralysis, and brain activity that closely resembles wakefulness. Most vivid dreaming occurs during this stage, and researchers believe _______________. A healthy night typically cycles through both stages four or five times, with non-REM dominating the early hours and REM periods lengthening toward morning. Disrupting either stage, through frequent awakenings or alcohol use, can leave a person feeling unrested even after a full night in bed.

주어진 문장: Researchers have found that people who use this method are significantly more likely to follow through on their goals than those who rely on willpower alone. Last January, Minji wrote the same resolution she always wrote: study English for an hour every day. ( ① ) By February, she had already quit, just as in previous years. Frustrated, she asked her teacher why her willpower always failed, and learned about a concept called implementation intentions. ( ② ) This idea, developed by psychologists, means forming a specific if-then plan that links a certain situation to a certain action in advance. ( ③ ) Instead of vaguely intending to study more, Minji made a precise plan: if she finished dinner, then she would study for thirty minutes. ( ④ ) She also prepared a backup plan: if she felt too tired, then she would study for just ten minutes instead of skipping entirely. ( ⑤ ) Because these plans removed the need to decide anything in the moment, starting became far easier for Minji. By December, she had studied for eleven straight months, proving that clear if-then plans beat vague intentions.
