When people encounter solid scientific evidence about climate change, we might expect them ①to accept it without hesitation. However, many individuals still dismiss or downplay such evidence, and psychologists explain this pattern through a concept called motivated reasoning. Motivated reasoning refers to the tendency to process information in a way that ②protects one's existing beliefs, identity, or lifestyle rather than to pursue objective truth. For example, a person whose livelihood depends on the fossil fuel industry may unconsciously search for reasons to doubt climate data, even while ③claim to value scientific accuracy. This happens because accepting uncomfortable facts can threaten a person's sense of self or ④demand costly lifestyle changes. Therefore, simply presenting more data rarely persuades a committed skeptic. Instead, experts suggest connecting climate information to values the person already holds, such as family safety or economic stability, so that acceptance feels ⑤natural rather than threatening.

Anthropologist Robin Dunbar proposed a concept now known as Dunbar's number, suggesting that human beings can only ①abandon about one hundred fifty stable social relationships at any given time. This limit, he argued, comes from the size of the human brain, which ②restricts how many meaningful connections a person can cognitively manage. In contrast, many social media users today have hundreds or even thousands of online friends and followers, a number far ③exceeding what Dunbar's research predicts. However, having numerous digital contacts does not necessarily mean that all of these relationships are ④close or emotionally supportive. Most users, when asked, admit that they interact regularly with only a small fraction of their total followers, while the rest remain largely ⑤unnoticed.

Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle that ① governs when we feel alert and when we feel drowsy. This clock is regulated primarily by a tiny cluster of neurons in the brain that responds to light entering through the eyes. When morning sunlight strikes the retina, the cluster signals the body to ② suppress sleep hormones and raise body temperature, preparing us for activity. As evening approaches and light fades, the same mechanism triggers the release of melatonin, a hormone that ③ promotes drowsiness. Because this rhythm evolved around the natural cycle of day and night, modern habits such as staying indoors under artificial light or working night shifts can push the internal clock ④ out of sync with the external environment. Such misalignment does not simply cause tiredness; it has also been associated with digestive problems and ⑤ heightened concentration, suggesting that timing matters as much as total sleep hours.

A smartwatch strapped to a runner's wrist can now do far more than simply count steps; it monitors heart rate variability, running form, and recovery time, then uses that data to suggest a training plan ① tailored to the individual rather than a generic weekly schedule. When the device detects signs of overtraining, such as an unusually high resting heart rate several mornings in a row, it may recommend a ② lighter workout or an extra rest day before fatigue turns into an actual injury. Amateur athletes often credit this kind of guidance with helping them train more ③ consistently without pushing their bodies too hard. Sports scientists note an important caveat, however: a wrist-based sensor cannot fully capture the same physiological detail available in a professional lab, so its suggestions should be treated as an ④ infallible medical judgment rather than a helpful guideline, particularly for anyone ⑤ managing a chronic health condition.

Long before a user finishes typing a sentence, the keyboard on most smartphones has already begun guessing what word comes next. This feature relies on a language model trained to notice which words commonly follow one another, so it can offer a shortlist of likely candidates, saving users countless keystrokes over the course of a day. This constant personalization, however, creates a subtle side effect that few users notice: some linguists worry that _______________.

Some changes in habit begin not with a big decision but with a quiet moment that lingers in the mind. (A) That changed when her class was assigned a documentary about plastic waste drifting through the ocean, footage she initially expected to find boring. Instead, watching seabirds mistake plastic fragments for food left her strangely unsettled, and she found herself thinking about the assignment long after class ended. (B) The next morning, almost without deciding to, she slipped her old tumbler into her backpack instead of buying a disposable cup on the way to school. It felt like a small, meaningless gesture at first. However, as weeks passed, she realized that consistently choosing the tumbler, declining a plastic straw, and reusing a shopping bag were quietly adding up. Small choices, she discovered, become meaningful once repeated. (C) Until last spring, Minji rarely thought twice about tossing a paper cup into the trash after finishing her coffee. Environmental issues seemed distant, something scientists and politicians should handle rather than an ordinary student like her.

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.

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. (A) 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 recorded in a sleep laboratory. (B) 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 waking up fully. (C) Because these interruptions rarely produce a clear memory the next morning, many people remain unaware that anything is wrong, even as chronic fatigue, headaches, and irritability build up over months.

Treating only one side of this equation, therefore, often leaves the other free to sustain the sleeplessness on its own. 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. ( ① ) A common trigger is what researchers call cognitive hyperarousal, in which the mind continues to race with worries about work, relationships, or even the inability to sleep itself, creating a frustrating cycle where anxiety about insomnia becomes a cause of insomnia. ( ② ) 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. ( ③ ) Poor sleep habits, including irregular bedtimes and excessive screen use before bed, can further weaken the body's internal signals for sleep onset. ( ④ ) 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. ( ⑤ )

주어진 문장: This heightened sensitivity can manifest in a variety of noticeable ways. In recent years, mental health experts have identified a distinct emotional response to environmental crisis, commonly called eco-anxiety. ( ① ) Eco-anxiety describes persistent worry, grief, or fear triggered by awareness of climate change and its consequences for the future. ( ② ) Although people of all ages can experience it, teenagers and young adults seem especially vulnerable, since they anticipate living through decades of worsening conditions. ( ③ ) Common symptoms include difficulty sleeping, a sense of hopelessness, and guilt over ordinary choices such as travel or diet. ( ④ ) For example, some students report feeling paralyzed whenever they read alarming climate news, unable to focus on schoolwork or hobbies. ( ⑤ ) However, experts emphasize that eco-anxiety is not a disorder to be eliminated but a natural reaction that can be channeled productively. Rather than avoiding the topic, young people are encouraged to join community projects, since taking constructive action tends to restore a sense of control and ease overwhelming distress.
