Three-dimensional printing technology is changing how products are designed and manufactured across many industries. Unlike traditional manufacturing, which often requires expensive molds and long production times, 3D printers can create ①simple objects directly from digital files within hours. This flexibility allows companies to produce small batches of customized products without the massive costs typically associated with mass production. Hospitals now use 3D printing to create prosthetic limbs tailored ②precisely to individual patients, while automakers use it to build lightweight parts that ③reduce vehicle weight. Small businesses, too, have benefited enormously, since the technology ④lowers the barrier to entry for entrepreneurs. However, experts caution that 3D printing still struggles to ⑤match the speed of mass production for extremely large orders.

Rather than displaying products in the usual manner, the team designed the space to resemble a colorful garden, inviting visitors to explore and take photographs. Lines formed outside the store within days, even though the products themselves were already available online. Curious about this success, a marketing researcher later interviewed several visitors, who explained that the temporary nature of the event made the experience feel special and worth attending in person. When the two weeks ended, the brand reported a significant ①decrease in both sales and social media followers. ②Encouraged by these results, the company ③began planning ④additional pop-up events in ⑤other cities.

When Mina was a freshman, she often spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study in which children could eat one marshmallow ①immediately or wait for two. Researchers found that children who waited ②longer showed better academic performance and self-control years later. This ability to ③resist an immediate reward in favor of a larger future one is known as delayed gratification. Inspired by the study, Mina began saving half of her allowance each week instead of spending it all on snacks. At first, resisting small purchases felt surprisingly ④easy, especially when her friends were eating out. After three months, however, she had ⑤saved enough to buy a bicycle she had wanted for over a year.

Companies argue that this approach benefits consumers by showing advertisements that are more ①relevant to their actual interests rather than random, generic promotions. However, many critics contend that this level of tracking raises serious concerns about privacy, since users rarely understand how ②extensively their behavior is being monitored. Furthermore, personalized advertising can trap users in a narrow bubble, ③limiting their exposure to alternatives. Supporters counter that consumers who dislike targeted ads can simply adjust their privacy settings, though ④few people actually take the time to do so. Given these competing concerns, policymakers must strike a ⑤careless balance between allowing innovation and protecting individual privacy rights.

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.

FOMO refers to the anxious feeling that arises when people believe they are missing out on rewarding experiences that others are having. (A) For instance, a student who sees photos of a gathering she missed may feel sudden regret, even though the event is already over. (B) This feeling often leads people to check their phones compulsively, which makes it hard to focus on tasks at hand. (C) Such experiences are common among heavy social media users, who constantly compare their lives with the curated posts of others.

Sleep apnea is a disorder in which breathing repeatedly stops and restarts during sleep, often because the muscles at the back of the throat relax too much and block the airway. (A) Doctors therefore rely less on a patient's own account of the night and more on objective measurements, such as overnight oxygen levels and airflow patterns recorded in a sleep laboratory. (B) Each pause can last from a few seconds to over a minute, and it may occur dozens of times in a single night without the sleeper ever waking up fully. (C) Because these interruptions rarely produce a clear memory the next morning, many people remain unaware that anything is wrong, even as chronic fatigue, headaches, and irritability build up over months.

Wearable devices that track sleep have become enormously popular, promising a detailed breakdown of light, deep, and REM sleep each night. (A) Despite these limitations, many users have come to treat the nightly score generated by their device as an objective medical verdict, sometimes experiencing anxiety when the number falls below what they expect, a phenomenon researchers have begun calling orthosomnia. (B) Independent studies comparing wearable data with polysomnography, the gold-standard method used in clinical sleep labs, have found that consumer devices are reasonably accurate at distinguishing sleep from wakefulness but considerably less reliable at identifying specific sleep stages. Some trackers overestimate deep sleep, while others underestimate the amount of time spent in REM sleep, and the margin of error can vary widely between brands. (C) These gadgets typically rely on movement sensors and heart rate monitors to estimate sleep stages, since directly measuring brain activity would require equipment found only in a sleep laboratory. This indirect approach, however, introduces significant uncertainty.

주어진 문장: Some researchers even suggest that painting rooftops white could further help reflect sunlight away from buildings. On a summer evening, downtown streets often feel noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. ( ① ) This phenomenon, known as the urban heat island effect, occurs when cities retain more heat than surrounding rural areas because of their dense concentration of asphalt, concrete, and buildings. ( ② ) Unlike soil or vegetation, which absorb and release heat gradually, these man-made surfaces absorb sunlight during the day and slowly radiate it back at night, preventing temperatures from cooling. ( ③ ) Tall buildings packed closely together also block wind, trapping warm air within narrow streets. ( ④ ) In contrast, areas with abundant trees and open water naturally stay cooler, since plants release moisture that helps lower surrounding temperatures. To reduce this effect, many cities have begun installing rooftop gardens and expanding public parks, hoping that additional greenery will absorb less heat than pavement does. ( ⑤ )

주어진 문장: Every rainy season, the water rose a little higher, leaving the villagers increasingly anxious about their future. Mira had lived in a coastal village since birth, watching the tide creep closer to her family's doorstep every year. ( ① ) When the sea finally swallowed the rice paddies that had fed her village for generations, her parents decided that staying was no longer possible. ( ② ) Together with many neighbors, they packed what little they could carry and moved inland, becoming what experts now call climate migrants, people forced to abandon their homes because of rising seas, droughts, or other disasters. ( ③ ) This term, rarely used a decade ago, has become increasingly common as extreme weather displaces communities worldwide. ( ④ ) Mira missed her old house terribly, yet she slowly began to build a new life in the crowded city, learning to adapt just as her ancestors once had. ( ⑤ ) International organizations, however, still struggle to agree on how to protect people like her, since climate migrants are not officially recognized as refugees under current law.
