Setting a goal such as 'I will study harder' rarely ①leads to meaningful improvement. According to psychologists Edwin Locke and Gary Latham, specific and challenging goals ②produce far better performance than vague or easy ones. This idea, known as goal-setting theory, suggests ③that clear targets direct attention and sustain effort over time. To apply this theory effectively, many educators recommend the SMART framework, which ④require goals to be Specific, Measurable, Achievable, Relevant, and Time-bound. Because the goal includes a clear number and a deadline, progress becomes easy ⑤to track and evaluate.

Insomnia is rarely caused by a single factor; it usually emerges from an interaction between psychological stress and physiological arousal that ①keeps the body from settling into sleep. A common trigger is what researchers call cognitive hyperarousal, in which the mind continues ②to racing 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. At the same time, the body's stress response system can become chronically activated, ③releasing 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. Poor sleep habits, including irregular bedtimes and excessive screen use before bed, can further ④weaken 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 ⑤relying on medication alone.

Sociologist Erving Goffman argued that people constantly perform for others, much like actors ①managing their image on a stage, a concept known as impression management. This idea applies vividly to social media, where users select flattering photos and delete posts ②that might damage their reputation. Such careful curation allows people ③to present an idealized version of themselves that emphasizes achievements while hiding struggles or ordinary moments. However, when this performance becomes constant, a troubling gap can form between one's authentic self and the polished character ④displaying online. Maintaining that gap requires considerable emotional energy, and studies suggest it often leads to anxiety and exhaustion. Furthermore, comparing one's own carefully staged life to others' equally staged posts can distort what people believe is normal. Therefore, individuals should recognize that some self-presentation online is inevitable, but they must also protect space where imperfection ⑤is allowed to remain visible.

When Mina was a freshman, she often ①spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study ②in which children could eat one marshmallow immediately or wait for two. Researchers found that children who waited longer ③shown better academic performance and self-control years later. Inspired by the study, Mina began ④saving half of her allowance each week instead of spending it all on snacks. After three months, however, she had saved enough to buy a bicycle she had ⑤wanted for over a year.

Instead of typing keywords into a search bar, a growing number of people now simply upload a photo and let an algorithm figure out what it contains. Shoppers use it to find where an item seen on the street can be purchased, while students use it to identify plants, insects, or historical artworks in seconds. The system works by breaking an image down into countless small features, such as edges, colors, and shapes, then matching that pattern against millions of stored examples. It is not flawless, however; a blurry photo, an unusual camera angle, or an object partly hidden behind another can easily confuse the algorithm, leading to _______________.

The term green premium _______________. 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. This price gap frequently discourages shoppers who support sustainability in principle but cannot justify the additional expense within a limited household budget. In contrast, wealthier consumers can absorb the premium more easily, which creates unequal participation in green markets. 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. 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.

During sleep, the brain does not simply rest; it actively reorganizes the day's experiences into lasting memories through a process called consolidation. Newly formed memories are initially fragile and stored primarily in a brain region called the hippocampus, which has limited long-term capacity. While a person sleeps, particularly during the deep stages of non-REM sleep, neural activity replays these fresh memory traces in rapid, compressed sequences, gradually transferring the information to the cortex for more durable, long-term storage. This replay strengthens the connections between neurons that encoded the original experience, making the memory more resistant to interference from unrelated events the following day. Sleep researchers have demonstrated this effect experimentally: participants who slept after learning a list of word pairs recalled more items the next day than participants who remained awake instead. Crucially, the benefit was not limited to simple recall; sleep also seemed to help participants extract general patterns from the material, suggesting that _______________.

ESG management refers to a company's efforts to consider Environmental, Social, and Governance factors alongside profit when making business decisions. Investors increasingly rely on ESG ratings to judge whether a company is managed responsibly and sustainably over the long term. Recently, however, many corporations have learned to boost their ESG scores without genuinely transforming their operations. Some firms publish glossy reports filled with impressive statistics while their actual carbon emissions barely decline, exploiting the fact that ESG evaluation systems still lack consistent global standards. This gap between appearance and substance has led critics to demand stricter, more transparent criteria for measuring corporate responsibility. Genuine ESG management, in contrast, requires _______________. Investors who wish to identify truly responsible companies should therefore examine detailed disclosures instead of trusting labels alone.

Online advertising has become increasingly personalized as algorithms analyze user behavior in real time. (A) Critics, however, warn that this precision can be used to exploit psychological weaknesses rather than genuinely help consumers. (B) Supporters claim that this precision benefits users by reducing the number of irrelevant advertisements they encounter. (C) Given these opposing views, many experts call for greater transparency about how such algorithms actually operate.

When people consistently sleep too little, the body's hormonal balance shifts in ways that can quietly encourage weight gain. (A) Two hormones in particular play opposing roles in regulating appetite: leptin signals fullness to the brain, while ghrelin stimulates the sensation of hunger. (B) At the same time, insufficient sleep interferes with how efficiently the body processes glucose, making cells less responsive to insulin and leaving more sugar circulating in the bloodstream than usual. Over months or years, this combination of increased appetite and reduced insulin sensitivity can contribute to steady weight gain and raise the risk of developing type 2 diabetes. (C) Studies show that sleep deprivation lowers leptin levels while raising ghrelin levels, so a tired body ends up feeling hungrier than it actually needs to be, even after a normal-sized meal.
