Psychologist Leon Festinger introduced social comparison theory, which explains that people ①evaluate their own abilities and opinions by comparing themselves with others. According to this theory, individuals engage in upward comparison when they measure themselves against someone who appears more ②successful, attractive, or accomplished. For instance, a teenager browsing vacation pictures posted by classmates may begin to feel that her own ordinary life is somehow ③inadequate. Unlike comparing oneself with someone in a similar position, which can sometimes ④boost confidence, upward comparison frequently triggers envy, dissatisfaction, and lower self-esteem. Researchers have found that frequent upward comparison online is linked to ⑤lower depression and anxiety.

As a result, the ads that appear on a person's screen often feel remarkably ①specific, sometimes referencing items browsed only minutes earlier. Supporters argue that this level of precision benefits consumers by ②reducing exposure to irrelevant advertisements and highlighting products they genuinely need. Some researchers have found that people who see highly personalized advertisements make impulsive purchases ③less frequently than those who see generic ones. Because these algorithms operate largely without public oversight, few consumers fully understand how their personal data shapes what they eventually buy. Greater ④transparency, many experts argue, would allow consumers to make more ⑤informed decisions about their own online behavior.

When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers belonged only to a handful of government scientists. During an internship, he helped design a small satellite intended to monitor crop health from orbit, a project that combined engineering with agricultural science. He realized that ___________. After graduation, Daniel joined a startup developing lunar landing equipment, a job that barely existed when he first imagined his future career.

Sleep debt refers to the cumulative gap between the amount of sleep a person needs and the amount they actually get. Unlike a financial debt, however, this deficit cannot simply be repaid with a single long weekend of rest. When someone loses two hours of sleep every night for a week, the body does not treat the shortage as fourteen separate small losses; instead, it accumulates the deficit, and _______________. Researchers have found that even modest, chronic sleep restriction gradually impairs reaction time and decision-making, often without the affected person noticing the decline. This is because subjective feelings of tiredness tend to plateau after a few days, even as objective performance keeps deteriorating. Consequently, people frequently underestimate how much sleep debt they are carrying until a demanding task suddenly exposes the accumulated cost.

Wearable devices that track sleep have become enormously popular, promising a detailed breakdown of light, deep, and REM sleep each night. These gadgets typically rely on movement sensors and heart rate monitors to estimate sleep stages, since directly measuring brain activity would require equipment found only in a sleep laboratory. This indirect approach, however, introduces significant uncertainty. Independent studies comparing wearable data with polysomnography, the gold-standard method used in clinical sleep labs, have found that _______________. Some trackers overestimate deep sleep, while others underestimate the amount of time spent in REM sleep, and the margin of error can vary widely between brands. Despite these limitations, many users have come to treat the nightly score generated by their device as an objective medical verdict, sometimes experiencing anxiety when the number falls below what they expect, a phenomenon researchers have begun calling orthosomnia.

Breaking the bystander effect requires more than good intentions; it requires concrete action from those who witness cruelty online. (A) Simply reporting an abusive post to platform moderators, for example, can remove harmful content before it spreads further. (B) Even small gestures, such as privately messaging the victim with words of support, can reduce the isolation that targets of cyberbullying often feel. (C) Both of these actions demonstrate that individual witnesses possess more power to help than the bystander effect leads them to believe.

Loyalty programs have become a standard feature of modern retail strategy. (A) Critics counter that such programs often reward habit rather than genuine satisfaction with a product. (B) Supporters claim that points and rewards encourage customers to return again and again. (C) True loyalty, they argue, should be built through consistent quality rather than artificial incentives.

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

주어진 문장: Not everyone, however, feels this financial burden equally, since household circumstances vary widely. The term green premium describes the extra cost that consumers must pay when they choose an environmentally friendly product or energy source over a conventional, cheaper alternative. ( ① ) For example, an electric vehicle or solar-powered appliance often carries a higher price tag than its gasoline-powered or coal-based counterpart, even though it produces fewer emissions over time. ( ② ) This price gap frequently discourages shoppers who support sustainability in principle but cannot justify the additional expense within a limited household budget. ( ③ ) In contrast, wealthier consumers can absorb the premium more easily, which creates unequal participation in green markets. ( ④ ) To narrow this gap, governments have introduced subsidies and tax credits that lower upfront costs, while companies invest in research to make clean technologies cheaper to manufacture. ( ⑤ ) As production scales up and innovation continues, many economists expect the green premium to shrink steadily, eventually making sustainable choices the more affordable option for most consumers.

This connection is not merely correlational; sleep appears to directly supply the raw materials the immune system needs. When the body fights off an infection, the immune system relies heavily on adequate sleep to function effectively. ( ① ) During deep sleep, the body produces and releases cytokines, proteins that help regulate immune responses and coordinate the fight against harmful invaders such as viruses and bacteria. ( ② ) People who consistently sleep fewer than six hours a night show measurably weaker antibody responses after vaccination compared with those who sleep seven or eight hours, suggesting that sleep loss can blunt the immune system's ability to build lasting protection. ( ③ ) Chronic sleep deprivation also appears to promote low-grade inflammation throughout the body, a state that, over time, has been linked to a higher risk of heart disease and other chronic conditions. ( ④ ) 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. ( ⑤ ) This is why doctors often recommend extra sleep, not just medication, when someone is fighting an illness.
