Sleep apnea is a disorder in which breathing repeatedly stops and restarts during sleep, often because the muscles at the back of the throat ① 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 ② waking up fully. Because these interruptions rarely produce a clear memory the next morning, many people remain ③ 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 ④ subjective measurements, such as overnight oxygen levels and airflow patterns recorded in a sleep laboratory. 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 ⑤ urgent than its subtle nighttime symptoms might suggest.

Social media researchers use the term context collapse to describe what happens when a single online post reaches audiences that would normally remain ①separate in offline life. In daily interactions, people naturally adjust their tone and content depending on whether they are speaking with family, close friends, or professional colleagues. However, a typical social media feed ②merges these distinct audiences into one undivided crowd, since a single post can simultaneously reach parents, employers, and casual acquaintances. Consequently, users often struggle to decide which version of themselves to present, knowing that a joke suitable for close friends might seem ③professional to a supervisor. This tension forces many users to either ④self-censor heavily or maintain multiple separate accounts tailored to different audiences. Understanding context collapse helps explain why online communication often feels more ⑤complicated.

When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers belonged only to a handful of government scientists. By the time he entered university, however, the space industry had changed ①dramatically, as private companies began launching satellites and building reusable rockets. Daniel studied aerospace engineering, drawn to the idea that space exploration was no longer ②limited to a few national agencies. During an internship, he helped design a small satellite intended to ③monitor crop health from orbit. He realized that the space industry now needed not only pilots and engineers but also data analysts, technicians, and even lawyers familiar with international space regulations. After graduation, Daniel joined a startup developing lunar landing equipment, a job that ④barely existed when he first imagined his future career. His story shows how commercial space ventures have ⑤closed doors that once seemed impossibly narrow.

After a strenuous workout, muscle fibers experience thousands of microscopic tears, and the body immediately begins a repair process that depends heavily on amino acids, the building blocks that protein supplies. This is why sports scientists recommend consuming protein within a couple of hours after training, since _______________. Many athletes assume that eating an enormous quantity of protein in a single sitting will speed up this process, but the body can only use a limited amount at once; the rest is simply burned for energy or stored as fat.

Insomnia is rarely caused by a single factor; it usually emerges from an interaction between psychological stress and physiological arousal that keeps the body from settling into sleep. A common trigger is what researchers call cognitive hyperarousal, in which _______________. At the same time, the body's stress response system can become chronically activated, releasing hormones such as cortisol that keep heart rate and body temperature elevated at night, both of which interfere with the natural drop in arousal needed to fall asleep. Poor sleep habits, including irregular bedtimes and excessive screen use before bed, can further weaken the body's internal signals for sleep onset. Because these psychological and physiological factors reinforce one another, effective treatment for chronic insomnia addresses both the racing mind and the underlying pattern of physical tension, rather than relying on medication alone.

Airlines and other companies often invite customers to pay a small extra fee to offset the carbon released by their trips. (A) As a result, purchasing an offset can become a convenient way to avoid making harder, more meaningful changes to one's actual carbon footprint. (B) This option relies on carbon offsets, credits that fund projects like tree planting or renewable energy in exchange for supposedly canceling out one's own emissions. (C) Critics point out, however, that many such projects would have occurred regardless of the funding, meaning the offset achieves little real, additional benefit.

The pace of technological change has forced professionals to rethink how they approach their careers. (A) As a result, many now treat learning as an ongoing part of their careers rather than something that ends at graduation. (B) A skill considered valuable just five years ago may already be outdated today, forcing workers to update their knowledge constantly. (C) Naturally, some professionals find this constant demand for new skills stressful and difficult to manage alongside other responsibilities.

When the body fights off an infection, the immune system relies heavily on adequate sleep to function effectively. (A) Rather than being a passive state in which the body simply rests, sleep functions as an active period during which the immune system repairs itself and prepares for future threats, which is why doctors often recommend extra sleep when someone is fighting an illness. (B) Chronic sleep deprivation also appears to promote low-grade inflammation throughout the body, a state that has been linked to a higher risk of heart disease and other chronic conditions. (C) During deep sleep, the body produces and releases cytokines, proteins that help regulate immune responses, and people who consistently sleep fewer than six hours a night show measurably weaker antibody responses after vaccination.

주어진 문장: This constant awareness of human presence is what distinguishes cobots from older industrial machines. Modern factories increasingly rely on collaborative robots, often called cobots, which are designed to work safely alongside human employees. ( ① ) Unlike traditional industrial robots that operate behind safety cages, cobots use sensors to detect nearby workers and adjust their movements accordingly. ( ② ) This technology allows humans and machines to share the same workspace without the risk of dangerous accidents. ( ③ ) In practice, cobots typically handle repetitive or physically demanding tasks, while human workers focus on tasks that require judgment and fine motor skills. ( ④ ) This division of labor increases overall efficiency, since each side contributes what it does best. ( ⑤ ) Manufacturers who have introduced cobots report fewer workplace injuries and higher worker satisfaction.

주어진 문장: In short, Fogg's model reminds us that ease of action, not sheer willpower, drives lasting behavior change. Many people believe that building a new habit requires strong willpower or motivation. ( ① ) However, psychologist BJ Fogg argues that habits form more easily when a behavior itself becomes simple to perform. ( ② ) His theory, called the Fogg Behavior Model, states that a behavior happens only when motivation, ability, and a prompt occur together. When motivation is low, the task must be made extremely easy, or it will not happen at all. ( ③ ) For instance, a person who wants to exercise daily succeeds more often by committing to one push-up than to a long workout. Fogg calls this idea the law of least effort, since people naturally choose the option requiring the least energy. ( ④ ) A student who wants to read more might leave a book open on the desk rather than setting a vague goal. By lowering the required effort, people reduce the ability barrier and make steady action far more achievable. ( ⑤ )
