Psychologist John Suler proposed a concept called the online disinhibition effect, ①describing how people behave differently on the internet than they do face to face. Because usernames often hide real identities and screens ②create physical distance from others, individuals feel freer to express themselves without immediate social consequences. This freedom can be beneficial, allowing shy people to share honest feelings they would normally hesitate ③to reveal in person. However, the same anonymity frequently produces a darker outcome, encouraging users to post cruel comments they would never say to someone's face. Malicious remarks left under celebrities' photos or news articles ④illustrates how quickly this behavior can spread once a few users set the tone. Such comments often cause severe emotional harm to the people who ⑤receive them.

Many people believe that ①building a new habit requires strong willpower or motivation. However, psychologist BJ Fogg argues that habits form more easily when a behavior itself ②become simple to perform. His theory, called the Fogg Behavior Model, states that a behavior happens only when motivation, ability, and a prompt ③occur together. When motivation is low, the model suggests, the task must ④be made extremely easy, or it will not happen at all. 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 ⑤requiring the least energy.

Adaptive learning apps promise something no traditional classroom can easily offer: a lesson plan that adjusts itself to each individual student in real time. As a student answers practice questions, the app ①tracks which concepts are mastered and which remain shaky, then quietly reshuffles the next set of problems to target the weaker areas. Early studies suggest that this ②personalized pacing can help struggling students catch up faster than a one-size-fits-all worksheet ever could. However, critics ③caution that an app cannot replace the encouragement, humor, and flexibility a human teacher brings to a lesson, especially when a student is frustrated rather than simply behind. There is also a subtler concern: students who grow used to ④instant, algorithm-generated feedback may struggle later with the slower, more ambiguous kind of feedback that real-world tasks and mentors typically provide, which could ⑤strengthen their ability to handle uncertainty outside the app.

Coaches have traditionally focused athlete preparation on training volume and nutrition, but a growing body of research suggests that sleep deserves ①equal attention. During deep sleep, the body releases growth hormone, a substance essential for repairing muscle tissue damaged during intense training, while the brain ②consolidates motor skills practiced earlier that day into more stable, efficient patterns. Athletes who sleep fewer than seven hours a night have been shown to suffer ③more injuries, slower reaction times, and reduced accuracy compared to well-rested peers performing the identical drills. Frequent travel across time zones ④simplifies this challenge considerably, since jet lag can disrupt an athlete's natural sleep-wake cycle for several days after a long flight, sometimes right before an important competition. In response, many professional teams now employ sleep specialists who design travel schedules, control bedroom lighting and temperature, treating sleep as an ⑤active and measurable component of overall athletic training.

When people discuss climate change, they often focus only on rising temperatures or melting ice, treating it as a purely scientific issue. However, the concept of climate justice reminds us that the causes and consequences of climate change are distributed ①evenly across the globe. Wealthy, industrialized nations have historically released the ②largest share of greenhouse gases while building their economies, yet developing nations, which contributed comparatively little, frequently suffer the most ③severe droughts and floods. This gap between responsibility and suffering raises a serious ④ethical question that science alone cannot answer. For example, a farming community in a low-income country may lose its entire harvest to an unusual flood, even though its members have never owned a car or flown on a plane. Therefore, tackling climate change requires more than new technology; it demands ⑤fair policies supporting the very communities least responsible for causing the crisis.

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.

Psychologist Roy Baumeister proposed a concept called ego depletion theory, which suggests that ___________. According to this theory, every act of self-control, from resisting a snack to concentrating on difficult homework, draws from the same limited mental resource. As this resource becomes depleted throughout the day, later decisions require more effort and are more likely to fail. For instance, someone who exercises discipline avoiding distractions all morning may struggle to resist checking a phone by evening. Likewise, dieters report that self-control weakens sharply at night, after hours of resisting food. Some researchers argue that short breaks, adequate sleep, and blood sugar levels can help restore this depleted resource. Although later studies have questioned how strong this effect is, the theory still offers a useful framework for understanding why willpower seems to fade throughout a long day.

Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. This theory explains that every habit begins with a cue, a signal that tells the brain to start an automatic behavior. The brain then performs a routine, which is the action itself, whether physical or mental. Finally, the brain receives a reward, a positive feeling that makes it want to repeat 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 without conscious thought. Because this loop operates automatically, breaking a bad habit requires ___________. Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.

A documentary director named Mira first traveled to a remote Arctic glacier to film its towering cliffs of blue ice, which seemed frozen in time. Standing before the massive wall, she assumed such an enormous structure could hardly change within a lifetime. Five years later, however, she returned to the very same coordinates, expecting her camera to capture an identical scene. Instead, she discovered that the glacier had retreated so dramatically that the ice cliffs, once visible from her original position, had nearly disappeared, leaving bare rock and pools of meltwater behind. Comparing the two sets of footage side by side, Mira realized that _______________. This encounter convinced her that climate change, which she had previously regarded as a distant statistic, was in fact an urgent process reshaping landscapes before her eyes.

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.
