Limited-edition products are goods that are released in small quantities for a ①short period of time. Many companies use this strategy because scarcity naturally ②decreases how much people desire an item. When consumers believe that a product will disappear soon, they often feel ③pressured to buy it immediately rather than wait. This excitement is ④intensified by social media, where people proudly share photos of items that others could not obtain. As a result, some shoppers later ⑤regret spending money on products they rarely use afterward.

VO2 max, defined as the maximum volume of oxygen a person's body can consume and use during intense exercise, is widely regarded as one of the best single indicators of cardiorespiratory fitness. Elite endurance athletes typically post VO2 max values far ①higher than those of untrained individuals, reflecting hearts that pump larger volumes of blood and muscles that extract oxygen from that blood with remarkable efficiency. While genetics accounts for a substantial portion of an individual's potential VO2 max, consistent aerobic training can still ②raise the measurement considerably over months of dedicated effort. Interval training, which alternates short bursts of near-maximal effort with periods of recovery, has proven particularly ③effective at improving this measurement compared to steady, moderate-intensity exercise alone. It is worth noting, however, that a high VO2 max does not guarantee success in competition, since factors such as running economy, pacing strategy, and mental resilience also play a ④decisive role in determining who actually crosses the finish line first. These additional factors remain ⑤irrelevant to overall performance.

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.

Have you ever felt a boring class lasted forever while an exciting weekend disappeared in an instant? This common experience reflects what psychologists call the distortion of time perception: ___________. Researchers explain that people who focus intensely on an enjoyable activity process fewer separate moments, so time seems to pass quickly. In contrast, bored or anxious people pay closer attention to each moment, making time feel as though it is dragging.

A flexitarian is someone who mainly eats plant-based meals but occasionally includes meat or fish, unlike a strict vegetarian who avoids animal products entirely. This flexible diet has recently gained attention as a practical way to fight climate change, since raising livestock produces a significant portion of global greenhouse gas emissions. Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at trapping heat in the atmosphere. By replacing just a few meat-based meals each week with vegetables, grains, or legumes, individuals can noticeably shrink their carbon footprint without giving up meat completely. Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a realistic first step, believing that _______________.

Sleep hygiene refers to a set of simple daily habits that help the body prepare for consistent, restorative rest. Experts commonly recommend going to bed and waking up at the same time every day, even on weekends, because an irregular schedule confuses the body's internal clock and makes it harder to fall asleep on demand. They also advise reserving the bedroom for sleep alone, since using the bed to study, scroll through a phone, or watch videos teaches the brain to associate that space with wakeful activity rather than rest. Physical environment matters as well: a cool, dark, and quiet room tends to produce deeper sleep than one that is warm, bright, or noisy. None of these individual habits guarantees a good night's sleep on its own, but together they form a routine that _______________, much the way a consistent set of cues trains an athlete's body to perform at a certain time each day.

Turning on automatic captions used to mean settling for garbled text full of obvious errors, but recent speech-recognition models have made same-language captions accurate enough that many viewers now leave them on by default. (A) For viewers who are deaf or hard of hearing, this improvement has quietly transformed everyday access to video content that once required a human transcriber and a considerable amount of time to caption properly. (B) The technology listens to audio, breaks it into individual sounds, and matches those sounds against a massive library of words and phrases to predict what was actually said. (C) The system still stumbles over overlapping speakers, strong accents, and specialized vocabulary, occasionally producing captions that are unintentionally funny.

Companies have discovered that ordinary advertisements no longer capture the attention of young consumers as effectively as they once did. (A) As a result, many brands now spend a large portion of their advertising budgets on influencer partnerships rather than television commercials. (B) This is because influencers build long-term relationships with their audiences, which makes recommendations feel personal rather than commercial. (C) However, brands must choose their partners carefully, since an influencer's reputation can directly affect how a product is perceived.

Climate change is not only a scientific and political issue but also an emotional one for many people today. (A) Teenagers and young adults tend to feel it most intensely, since they expect to live through many more decades of a changing climate than older generations do. (B) This emotional dimension, known as eco-anxiety, refers to persistent worry, grief, or fear that stems from awareness of climate change and its future consequences. (C) Fortunately, channeling this anxiety into constructive action, such as joining community environmental projects, can help restore a sense of control rather than deepen despair.

In other words, what looks like a lack of discipline may actually be a biological mismatch. Across many countries, high schools begin classes early in the morning, often before eight o'clock. ( ① ) This schedule assumes that teenagers can simply go to bed earlier to compensate, but biology tells a different story. ( ② ) During adolescence, the body's internal clock shifts later, delaying the release of melatonin until well after ten at night. ( ③ ) As a result, most teenagers are not physiologically ready to fall asleep until much later than younger children or adults are, and when early start times force them to wake before their bodies have completed a full sleep cycle, the mismatch accumulates into a chronic sleep debt that affects concentration and mood throughout the school day. ( ④ ) Researchers who study this mismatch argue that the underlying problem is not laziness or poor discipline among students, but a scheduling system built around adult rhythms rather than adolescent ones. ( ⑤ ) Some school districts that delayed their start times by thirty minutes reported improvements in attendance.
