Sleep apnea is a disorder in which breathing repeatedly stops and restarts during sleep, often because the muscles at the back of the throat relax too much and block the airway. Each pause can last from a few seconds to over a minute, and it may occur dozens of times in a single night without the sleeper ever ① waking up fully. Because these interruptions rarely produce a clear memory the next morning, many people remain ② unaware that anything is wrong, even as chronic fatigue, headaches, and irritability build up over months. Doctors therefore rely less on a patient's own account of the night and more on objective measurements, such as overnight oxygen levels and airflow patterns ③ recording in a sleep laboratory. ④ Left untreated, the disorder has been linked to serious long-term risks, including high blood pressure and heart disease, which makes an accurate diagnosis far more urgent than its subtle nighttime symptoms might ⑤ suggest.

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.

Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. This theory explains that every habit ①begins with a cue, a signal that tells the brain to start an ②automatic behavior. The brain then performs a routine, which is the action itself, whether physical or mental. Finally, the brain receives a reward, a ③negative feeling that makes it want to ④repeat the same behavior. For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run almost without ⑤conscious thought. Because this loop operates automatically, breaking a bad habit requires changing the routine while keeping the same cue and reward. Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.

These platforms allow individuals to sell clothing, electronics, and furniture directly to other consumers, cutting out traditional retail markups entirely. For younger buyers especially, purchasing secondhand items has become associated with ①resourcefulness rather than financial necessity. However, buying secondhand carries certain ②risks, since items cannot always be inspected closely before purchase, and some sellers misrepresent the condition of their products. To address this problem, many platforms now offer buyer protection programs and ③vague rating systems for sellers. As ④trust in these systems continues to grow, secondhand trading is expected to ⑤expand even further in the coming years.

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.

Exercise does far more than strengthen muscles and the heart; it also produces measurable changes within the brain itself. 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. Studies comparing physically active students to sedentary peers have repeatedly found that _______________, even when the exercise session ends well before the test begins. 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.

Online advertising has become increasingly personalized as algorithms analyze user behavior in real time. (A) Critics, however, warn that this precision can be used to exploit psychological weaknesses rather than genuinely help consumers. (B) Supporters claim that this precision benefits users by reducing the number of irrelevant advertisements they encounter. (C) Given these opposing views, many experts call for greater transparency about how such algorithms actually operate.

주어진 문장: This influence is so strong that many companies actively encourage customers to leave feedback after each purchase. Before making a purchase, most online shoppers now read reviews written by previous customers rather than relying solely on advertisements. ( ① ) These reviews, posted by people who have no financial connection to the seller, often seem more trustworthy than promotional claims. ( ② ) Research shows that products with a large number of positive reviews sell significantly more than those with few or no reviews at all. ( ③ ) However, fake reviews written by paid writers or even automated programs have become a serious problem, undermining consumer trust. ( ④ ) Platforms that fail to detect these fraudulent posts risk losing credibility with their users. ( ⑤ ) Ultimately, the power of online reviews depends entirely on their perceived honesty.

주어진 문장: This ability to anticipate desires so precisely raises an uncomfortable question about how much companies truly know about us. Modern advertising increasingly relies on personal data collected from users' browsing habits, search histories, and social media activity. ( ① ) Companies argue that this approach benefits consumers by showing advertisements that are more relevant to their actual interests rather than random, generic promotions. ( ② ) However, many critics contend that this level of tracking raises serious concerns about privacy, since users rarely understand how extensively their behavior is being monitored. ( ③ ) Some algorithms can predict purchasing decisions before consumers themselves are consciously aware of them. ( ④ ) Furthermore, personalized advertising can trap users in a narrow bubble, repeatedly showing them similar products and limiting their exposure to alternatives. ( ⑤ ) Given these competing concerns, policymakers must strike a careful balance between allowing innovation and protecting individual privacy rights.

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 )
