Building brand loyalty has traditionally been considered one of the most valuable goals in marketing, since loyal customers ①tend to spend more and recommend products to others. Companies invest significant resources in loyalty programs, ②offering points, discounts, and exclusive access to encourage repeat purchases. Genuine loyalty, critics contend, should be earned through consistent quality and honest treatment of customers, not through artificial incentives that merely ③delays a customer's departure. Furthermore, excessive focus on retaining existing customers can cause companies ④to neglect innovation, since they assume loyal buyers will continue purchasing regardless of improvements. Relying solely on loyalty programs without addressing underlying product quality may ultimately ⑤backfire.

A growing number of health apps now track steps, sleep, and heart rate throughout the day, ① quietly building a detailed picture of a user's physical condition without requiring a single visit to a doctor's office. By comparing this stream of data against patterns drawn from millions of other users, the app's algorithm can flag early warning signs, such as an irregular heartbeat, long before the person ② experiencing it would have noticed anything unusual on their own. For people living far from specialists or unable to afford frequent checkups, this kind of constant monitoring can ③ feel like a genuine safety net. Doctors caution, however, that these apps ④ are designed to detect patterns, not to diagnose illness, and that a worried user should always confirm any alarming reading with a professional. Treating a wellness app as a substitute for medical expertise, they warn, can ⑤ being just as risky as ignoring a warning altogether.

Émile Durkheim insisted that sociology could become a genuine science only if it identified a ① distinct subject matter that could not be reduced to individual psychology. He termed this subject matter social facts, defined as ways of thinking, feeling, and acting that exist outside any single individual yet exert a ② coercive influence over that individual's behavior. Language, currency, legal codes, and religious ritual all qualify as social facts, since a person is born into these systems already fully formed and must ③ conform to them regardless of personal preference. Durkheim insisted that social facts should be studied as things, meaning they must be examined ④ empirically through observable patterns such as statistics. His study of suicide rates exemplified this method, showing that rates varied ⑤ randomly according to variables such as religious affiliation and marital status, patterns that could not be explained by individual psychology alone.

Parents and coaches sometimes worry that heavy resistance training might damage the growth plates in a young athlete's bones, cartilage regions near the ends of long bones that are ① responsible for lengthening as a child develops. This concern kept strength training out of many youth programs for decades. However, extensive research over the past twenty years has found ② little evidence that properly supervised resistance training harms growth plates in healthy children. The actual risk arises not from lifting weights itself but from ③ poor technique, excessive load, and inadequate supervision. Major pediatric and sports medicine organizations now generally agree that structured strength programs, when taught with correct form and appropriate weight, can safely ④ improve bone density, coordination, and injury resistance in young athletes. The key variable, in other words, is not whether children lift weights but how carefully that training is ⑤ ignored.

Across the world, teenagers are chronically short on sleep, often getting two or three hours less than the eight to ten hours experts recommend for their age. Part of the problem lies in biology: as puberty begins, _______________. Yet school start times rarely adjust to this shift, forcing students to wake before their bodies are ready. The consequences extend well beyond simple tiredness. Chronic sleep loss during adolescence has been linked to impaired concentration, weakened memory, and a higher risk of anxiety and depression. It can also disrupt the hormones that regulate appetite, contributing to unhealthy weight gain over time. Some school districts have experimented with delaying start times by even thirty minutes, and early results suggest that students who gain that extra rest show improved grades, better mood, and fewer tardy arrivals. Despite this evidence, changing entrenched school schedules remains a slow and contentious process.

Every spring, the volunteer club at our school introduces new members to its most popular project: the nursing home visit program. (A) For example, one member always brings her ukulele and plays simple songs that the residents remember from their youth. (B) As a result, both the students and the elderly residents look forward to these visits every month. (C) During each visit, members are encouraged to bring a small talent or hobby to share with the residents.

When sociologist Émile Durkheim studied suicide rates across different societies, he noticed something puzzling: rates rose not only during economic depression but also during sudden prosperity. (B) Decades later, Robert Merton extended the concept to explain deviance within stable societies, proposing that anomie also arises when a culture insists that everyone pursue identical goals while denying many people the legitimate means to achieve them. (A) He concluded that both crises share a common feature, the collapse of shared norms, a state Durkheim called anomie, arguing that rapid social change can strip away the moral guidelines that regulate human desire. (C) Faced with this gap between aspiration and opportunity, some individuals conform, but others turn to innovation, ritual, retreat, or rebellion.

Travelers who cross several time zones in a single flight often arrive feeling exhausted, foggy, and strangely out of sync with the local clock, a condition widely known as jet lag. (A) The discomfort arises because the body's internal clock, which governs sleep, hunger, and alertness, continues to run on the schedule of the departure city even after landing, and realigning it typically takes about one day for every time zone crossed. (B) Flying eastward tends to produce more severe symptoms than flying westward, because advancing the internal clock forward is generally harder for the body than delaying it. (C) Exposure to natural light at the right moments after arrival can help speed up the adjustment, since light is the strongest external cue the internal clock uses to reset itself.

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) 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. (B) 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. (C) 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.

In other words, the two stages appear to serve complementary purposes, one restoring the body and the other restoring the mind. 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. ( ① ) 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. ( ② ) This is the period most closely associated with physical restoration. ( ③ ) REM sleep, by contrast, brings rapid eye movements, near-total muscle paralysis, and brain activity that closely resembles wakefulness. ( ④ ) Most vivid dreaming occurs during this stage, and researchers believe it plays a central role in consolidating memories and processing emotional experiences. ( ⑤ ) 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.
