Marketers have long recognized that perceived scarcity, the sense that a product or opportunity ①are available only in limited quantity or for a limited time, can dramatically increase its desirability, even when the item's intrinsic qualities remain entirely unchanged. This phenomenon, known as the scarcity effect, operates on a simple psychological principle: when something appears difficult to obtain, people tend ②to infer that it must be valuable, since truly worthless items rarely generate genuine competition for possession. A retailer who labels a product as "limited edition" or displays a countdown timer beside a discounted offer exploits this inference, ③prompting customers to make hurried purchase decisions they might otherwise postpone or reconsider. Experimental studies confirm that identical products ④are rated as more desirable and often command higher prices when framed as scarce than when the same products are presented as widely and continuously available. The effect intensifies further when scarcity is attributed to high demand rather than to limited supply alone, since competition from other buyers ⑤introduces an additional layer of urgency absent from mere supply constraints.

The Greenfield Public Library will offer a variety of special programs ①for students during summer vacation. The reading club, ②designed for younger students, encourages children to read at least one book per week. The writing workshop helps older students ③improve their essay skills through fun and creative exercises. In addition, the library will host a special lecture series on careers, ④invited professionals from various fields to speak with students. All programs are free, but registration ⑤is required in advance because space is limited.

A printer that once produced only plastic prototypes can now deposit living cells layer by layer to build a structure that begins to ①resemble actual tissue. Bioprinting adapts the logic of conventional 3D printing, replacing plastic filament with a ②specialized ink made of living cells suspended in a gel that supports their survival while the shape sets. Printing a flat patch of skin or a simple blood vessel has already moved from laboratory curiosity to early clinical testing, since these tissues are thin enough for nutrients to reach every cell by ③diffusion. Printing a solid organ such as a kidney remains a far greater challenge, because internal cells ④thrive without their own blood supply, and no printer yet exists that can build a network of vessels fast enough to keep them alive. Researchers are therefore focusing on hybrid strategies, printing a rough scaffold and then allowing the tissue to mature and grow its own vasculature over ⑤time.

Summer is the best time to enjoy swimming pools, rivers, and beaches with family and friends. However, water activities can be completely ①safe without proper preparation. First, always swim in areas that are ②supervised by a lifeguard, and never swim alone even if you are a strong swimmer. Second, check the weather and water conditions before entering the water, since strong currents can make swimming extremely ③dangerous. Third, wear a life jacket in open water, especially if you are a beginner. Taking a break every hour will help you stay ④energetic, and learning basic rescue skills will make you more ⑤prepared for emergencies.

Facing a shortage of caregivers and a rapidly aging population, several countries have begun deploying robots designed to remind elderly residents to take medication, monitor for falls, and even offer simple conversation throughout the day. Early trials show that many residents report ①reduced loneliness, particularly when a robot's presence allows an overworked human staff member to spend a few extra minutes with each patient rather than rushing between rooms. Critics, however, worry that this framing quietly ②shifts the goal of care: instead of asking how technology can support human connection, institutions may come to treat a robot's companionship as an ③unacceptable substitute for it. Advocates for the elderly argue that robots should be evaluated strictly as tools that free up human time for human contact, ④never as a lower-cost replacement for the contact itself, since human presence remains ⑤irreplaceable.

A rational approach to decision-making dictates that only future costs and benefits should influence a choice, since resources already spent cannot be recovered regardless of what is decided next. In practice, however, people routinely allow such irrecoverable expenditures, known as sunk costs, to shape their subsequent decisions, a pattern referred to as the sunk cost fallacy. Economists therefore urge decision-makers to evaluate each choice based solely on its prospective outcomes, treating past expenditures as ___________ to the decision at hand.

Many people who try digital detox for the first time report feeling anxious within the first few hours. (A) This initial discomfort, sometimes called withdrawal anxiety, tends to fade after a day or two as the mind adjusts to reduced stimulation. (B) Once that adjustment period passes, most participants describe a noticeable sense of calm that they had not expected. (C) This unexpected calm often motivates people to repeat the practice regularly instead of treating it as a one-time experiment.

Retailers rarely leave the shopping environment to chance. (A) For instance, cheerful background music and pleasant lighting are chosen specifically to keep shoppers relaxed and unhurried. (B) Every detail, from store layout to background music, is carefully designed to influence customer behavior. (C) As a result, customers often spend more time browsing and end up buying items they never intended to purchase.

주어진 문장: Without such outside checks, companies could easily present exaggerated or even false claims as genuine achievements. As consumers become more aware of global social and environmental issues, many now expect companies to take responsibility beyond simply selling products. ( ① ) This expectation has given rise to ethical consumption, in which shoppers consider factors such as fair wages, humane treatment of animals, and environmental sustainability before making purchases. ( ② ) Companies that ignore these concerns risk public backlash, especially when unethical practices are exposed through investigative journalism or social media. ( ③ ) Some corporations have responded by publishing detailed sustainability reports, though critics question whether these documents reflect genuine change or merely serve as public relations tools. ( ④ ) Real accountability, according to many experts, requires independent verification rather than self-reported claims that cannot be easily checked. ( ⑤ ) Consumers, for their part, must also remain vigilant, since a company's marketing language does not always match its actual practices.

( ③ ) For example, the engineering booth will let students build a simple model bridge. ( ④ ) In addition, three guest speakers will give short talks about their career paths during the lunch break. ( ⑤ ) Teachers strongly encourage all students to attend.
