In the days leading up to an endurance event, many athletes deliberately increase their carbohydrate intake while reducing training volume, a practice ①known as carbohydrate loading. The strategy ②is design to maximize the amount of glycogen, the storage form of carbohydrate, packed into muscle tissue before competition begins. Because glycogen serves as the primary fuel source during prolonged, intense exercise, entering an event with fuller stores can delay the point of exhaustion that runners often ③call hitting the wall. Sports nutritionists caution, however, that the timing and composition of meals ④matter as much as the total quantity of carbohydrate consumed, since eating unfamiliar foods immediately before competition can cause digestive discomfort. Athletes are therefore advised ⑤to practice their nutrition strategy during training rather than experimenting with it for the first time on race day.

Elite athletes often perform in front of enormous crowds with championships, contracts, and years of training riding on a single moment, and the psychological weight of that pressure can ①undermine skills that feel automatic in practice. Sports psychologists explain that intense anxiety narrows attention and disrupts the smooth, unconscious execution of well-learned movements, a phenomenon sometimes ②called choking under pressure. Rather than trying to eliminate nervousness entirely, which research suggests ③are nearly impossible, many trainers now teach athletes ④to reinterpret the physical symptoms of anxiety, such as a racing heart, as signs of readiness rather than danger. Over time, repeated exposure to high-pressure situations in practice, deliberately ⑤simulated to resemble real competition, allows athletes to build tolerance the same way their muscles adapt to physical training.

Philosopher Harry Frankfurt devised a scenario ①to challenge a long-held assumption about moral responsibility: that a person can be blamed for an action only if they could genuinely have done otherwise. Imagine a man named Black who secretly implants a device in another man's brain, ②ready to force a particular decision if the second man shows any sign of choosing differently. The second man, however, decides entirely on his own to perform the very action Black wanted, and the device never ③activating at all. Black's hidden mechanism made it impossible for the man ④to have chosen otherwise, yet most people still consider him fully responsible for what he freely decided to do. Frankfurt used this scenario to argue that moral responsibility depends on the actual reasoning behind a choice, not on some abstract guarantee that an alternative path ⑤remained available the entire time.

Ambitious young athletes and the parents who support them sometimes assume that more training automatically produces ①better results, a belief that occasionally leads to a condition known as overtraining syndrome. Unlike ordinary fatigue that resolves after a few days of rest, overtraining syndrome develops ②rapidly within a single day of insufficient recovery, eventually producing persistent exhaustion, declining performance despite continued hard work, and increased susceptibility to illness and injury. Adolescents may be especially vulnerable, since their bodies are simultaneously coping with the physical demands of growth and the added stress of intensive training schedules. Warning signs are often ③subtle at first, including disrupted sleep, irritability, and a loss of enthusiasm for a sport the athlete once genuinely enjoyed. Recovery from full-blown overtraining syndrome can take ④months rather than days, which is why sports medicine specialists now emphasize monitoring early warning signs and scheduling rest before symptoms ⑤worsen.

Extended producer responsibility, a policy requiring manufacturers to bear responsibility for their products even after use, has been adopted by governments seeking to ①increase landfill waste. Under such schemes, companies must ②finance the collection and recycling of goods once consumers discard them, rather than leaving municipalities to absorb the cost. Advocates maintain that shifting this burden onto producers creates a powerful incentive to design products that are more ③durable, easily disassembled, and readily recyclable from the outset. Critics counter that the policy, whatever its theoretical merits, often fails to reduce waste meaningfully unless paired with ④rigorous enforcement and transparent reporting requirements. For instance, some manufacturers merely pass the added cost of compliance on to consumers, without making substantive changes to how products are designed. In contrast, jurisdictions that combine producer responsibility with strict eco-design standards and independent audits tend to witness ⑤genuine improvements in recyclability.

A smart thermostat that learns a family's daily rhythm can lower the temperature automatically before everyone wakes up cold, while smart lights that follow a resident's schedule no longer need to be switched on and off by hand. Sensors collect data about temperature, motion, and light throughout the home, and an algorithm gradually learns which settings match each household's actual habits. Yet convenience comes with a trade-off that many households overlook: _______________.

Exercise does far more than strengthen muscles and the heart; it also produces measurable changes within the brain itself. During sustained physical activity, the body releases a protein called brain-derived neurotrophic factor, which supports the growth of new neurons and strengthens connections between existing ones, particularly in regions associated with memory and learning. Studies comparing physically active students to sedentary peers have repeatedly found that _______________, even when the exercise session ends well before the test begins. Researchers believe that exercise increases blood flow to the brain, delivering oxygen and nutrients more efficiently, while also reducing levels of stress hormones that can interfere with clear thinking.

Walking through the old industrial district downtown, I noticed that a gray concrete wall had been transformed overnight into a wild swirl of color, letters, and cartoon figures. Some residents complained to the city office, calling it vandalism and demanding that workers paint over it immediately. Others argued that the same wall had been an ugly, forgotten eyesore for years, and that the graffiti artist had simply given it a voice no one else bothered to give it. This disagreement reveals a tension at the heart of street art: _______________. The line between vandalism and art, it seems, often depends less on the paint itself than on who gave permission to use the wall.

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. (A) Elite endurance athletes typically post VO2 max values far higher than those of untrained individuals, reflecting hearts that pump larger volumes of blood and muscles that extract oxygen with remarkable efficiency. (B) While genetics accounts for a substantial portion of an individual's potential VO2 max, consistent aerobic training can still raise the measurement considerably over months of dedicated effort. (C) It is worth noting, however, that a high VO2 max does not guarantee success in competition, since other factors such as pacing strategy and mental resilience also play a decisive role.

Even a modest level of dehydration, as little as two percent of body weight lost through sweat, can measurably reduce an athlete's endurance and cognitive sharpness during competition. (A) Dehydration also impairs the body's ability to regulate its own temperature, since sweating is the primary mechanism for releasing excess heat during intense exercise. (B) As fluid levels drop, blood volume decreases, forcing the heart to work harder to deliver the same amount of oxygen to working muscles, which accelerates fatigue. (C) Athletes competing in hot, humid conditions therefore face a particularly difficult balance, since sweating heavily to stay cool simultaneously depletes the very fluids needed to sustain performance.
