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 ①waking up fully. Because these interruptions rarely produce a clear memory the next morning, many people remain ②unaware 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 ③recording in a sleep laboratory. ④Left 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 ⑤suggest.

Modern advertising increasingly relies on personal data ①collected from users' browsing habits, search histories, and social media activity. Companies argue that this approach benefits consumers by showing advertisements that are more relevant to their actual interests. However, many critics contend that this level of tracking raises serious concerns about privacy, since users rarely understand how extensively their behavior ②is being monitored. Some algorithms can predict purchasing decisions before consumers themselves are consciously aware of them, ③which feel unsettling to many people. Furthermore, personalized advertising can trap users in a narrow bubble, repeatedly showing them similar products and ④limiting their exposure to alternatives. Supporters counter that consumers who dislike targeted ads can simply ⑤adjust their privacy settings.

Smart speakers have quietly become a fixture in many households, responding to spoken requests for weather updates, music, or kitchen timers. Because these assistants improve by learning from millions of interactions, they gradually become better at recognizing regional accents and casual phrasing that once confused them. Still, _______________. Engineers continue to refine these systems, but many admit that truly natural conversation remains one of the hardest goals in the entire field of artificial intelligence.

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. 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 experiencing it would have noticed anything unusual. Doctors caution, however, that these apps are designed to detect patterns, not to diagnose illness, and that _______________.

Self-driving technology is advancing rapidly, and its impact on the transportation industry is becoming increasingly visible. Companies are testing autonomous trucks that can travel long distances without human drivers, potentially transforming how goods move across countries. Supporters argue that this technology could ___________, since computers do not need rest and can react faster than humans in emergencies.

Job seekers often assume that their closest friends will be the most helpful source of career advice. (A) In fact, studies show that a surprising number of job offers come through acquaintances met only briefly at conferences or previous workplaces. (B) However, close friends usually work in the same field or social circle, so their knowledge of new openings tends to overlap with what the job seeker already knows. (C) This is because such acquaintances belong to different professional circles, giving them access to information that never reaches close friends.

Many economists have studied how automation affects different sectors of the economy, and their research reveals a consistent pattern. (A) For example, manufacturing plants that adopted robotics saw production speed double within five years, while the number of routine assembly jobs fell sharply. (B) As a result, workers today are encouraged to develop skills that complement machines rather than compete with them, such as creativity and critical thinking. (C) At first, automation mainly affected repetitive manual tasks in manufacturing, but it has since spread into administrative and even creative fields.

Telemedicine has sparked debate among healthcare professionals about its proper role in modern medicine. (A) Critics counter that virtual visits cannot fully substitute for physical examinations, which remain essential for diagnosing certain conditions accurately. (B) Most experts, weighing both sides, conclude that telemedicine works best as a complement to, rather than a replacement for, traditional care. (C) Supporters point out that virtual visits save time and extend healthcare access to patients living far from hospitals.

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. (A) 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. (B) What began as a playful novelty has become a default setting for many users, subtly adjusting nearly every selfie posted online. (C) Some social media platforms have responded by labeling heavily edited photos or banning certain filters that alter body shape.

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.
