Many people struggling to fall asleep in noisy environments turn to white noise machines, devices that ①emit a steady, uniform sound covering a broad range of frequencies. The appeal lies in a phenomenon called auditory masking, in which a constant background sound makes sudden noises ②less noticeable to the sleeping brain. Without this masking effect, an abrupt change in sound is far more likely ③to trigger a brief awakening, even if the sleeper does not consciously remember it the next morning. Studies comparing sleep in quiet rooms with sleep alongside white noise have found that participants using white noise ④experienced fewer of these brief awakenings. However, researchers caution that the benefit depends heavily on volume and consistency, since noise that is too loud or that ⑤varying unpredictably can itself become a source of disruption rather than a remedy.

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. What began as a playful novelty has become a ①default setting for many users, subtly adjusting nearly every selfie posted online. 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, a comparison that earlier generations never had to ②face. Some social media platforms have responded by ③labeling heavily edited photos or banning certain filters that alter body shape. Whether such small warnings can meaningfully ④worsen the daily flood of filtered images, however, remains an ⑤open question that researchers are only beginning to study.

After a strenuous workout, muscle fibers experience thousands of ①microscopic tears, and the body immediately begins a repair process that ultimately makes the muscle stronger than it was before. This repair depends heavily on amino acids, the building blocks that protein supplies, which is why sports scientists recommend consuming protein within a couple of hours after training. Waiting too long to eat can ②slow recovery, since a muscle's sensitivity to amino acids gradually declines once that window closes. Many athletes assume that eating an enormous quantity of protein in a single sitting will ③delay this process, but the body can only use a limited amount at once; the rest is simply burned for energy or stored as fat. For this reason, nutritionists generally advise spreading moderate portions of protein ④evenly across several meals throughout the day rather than saving it all for one large post-workout ⑤meal.

Social psychologists describe a phenomenon called the bystander effect, in which individuals become less likely to help a victim as the number of witnesses increases. Each observer assumes someone else will step in, and this diffusion of responsibility leaves no one willing to act. Cyberbullying magnifies this problem, since a single humiliating post can be witnessed by thousands of people scattered across the internet rather than a few standing nearby. Anonymity intensifies the effect further, allowing silent observers to scroll past cruel comments without feeling accountable for their inaction. Some bystanders even worry that intervening publicly might make them the bully's next target, so they choose to remain silent instead. However, silence signals approval to both the bully and the audience watching the exchange unfold. Experts insist that even a single supportive comment can disrupt this harmful pattern. Therefore, witnesses online must _______________.

Social media researchers use the term context collapse to describe what happens when a single online post reaches audiences that would normally remain separate 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 merges 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 unprofessional to a supervisor. For example, a party photo posted for friends could later damage someone's reputation if an employer notices it. This tension forces many users to either self-censor heavily or maintain multiple separate accounts tailored to different audiences. Understanding context collapse _______________.

Minji spent nearly every evening watching Jimin, an online creator who streamed cooking videos and chatted casually with her viewers. Over several months, Minji began to feel as though she truly knew Jimin, laughing at her jokes and worrying whenever she mentioned having a difficult week. Whenever Jimin responded to a comment, even a simple one, Minji felt a small thrill of connection, as if they were becoming closer friends. One day, Minji excitedly waited outside a fan event, hoping that Jimin would recognize her from the countless messages she had sent. However, Jimin greeted her the same way she greeted every other stranger in line, without any hint of personal recognition. Standing there, Minji slowly realized that ___________.

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.

FOMO refers to the anxious feeling that arises when people believe they are missing out on rewarding experiences that others are having. (A) For instance, a student who sees photos of a gathering she missed may feel sudden regret, even though the event is already over. (B) This feeling often leads people to check their phones compulsively, which makes it hard to focus on tasks at hand. (C) Such experiences are common among heavy social media users, who constantly compare their lives with the curated posts of others.

Many students assume that old social media posts disappear once enough time has passed. (A) A few years later, however, a teacher reviewing her application happened to notice an old, unkind comment she had posted and forgotten. (B) Minji, for instance, once left a careless comment mocking a classmate, assuming no one would ever see it again. (C) This experience taught her that a digital footprint, the lasting trail left by online activity, can resurface at unexpected moments.

Adaptive learning apps promise something no traditional classroom can easily offer: a lesson plan that adjusts itself to each individual student in real time. (A) As a student answers practice questions, the app tracks which concepts are mastered and which remain shaky, then quietly reshuffles the next set of problems to target the weaker areas. (B) Early studies suggest that this personalized pacing can help struggling students catch up faster than a one-size-fits-all worksheet ever could. (C) However, critics caution that an app cannot replace the encouragement, humor, and flexibility a human teacher brings to a lesson.
