Long before cognitive scientists possessed the tools to observe the brain directly, Donald Broadbent proposed an influential model suggesting that the human capacity to process incoming sensory information ①constrained by a structural bottleneck through which only a single stream of input can pass at any given instant. According to this filter theory, multiple channels of stimulation, such as competing voices in a crowded room, ②are initially registered at a shallow, physical level, but only one channel is selected for further, meaning-based analysis while the rest are blocked from advancing beyond that early filter. Although later researchers challenged the rigidity of this early selection mechanism, ③pointing to instances in which unattended information, such as one's own name, nevertheless ④breaks through and captures awareness, the core insight that attention imposes a genuine processing limit rather than a mere matter of willpower has remained remarkably durable. This basic bottleneck principle ⑤continues to inform contemporary explanations of why multitasking so reliably degrades performance on demanding tasks.

Over the past two decades, insights drawn from behavioral economics have moved beyond academic journals and into the machinery of government itself, ①reshaping how numerous public programs are designed and implemented. Tax authorities in several countries, for example, discovered that simply informing citizens how many of their neighbors had already paid overdue taxes on time substantially ②increased subsequent compliance rates, outperforming letters that merely threatened legal penalties for continued nonpayment. Public health agencies have applied similar principles to encourage preventive care, finding that appointment reminders phrased to emphasize the personal cost of a missed visit ③proved more effective than neutral reminders listing only the date and time. Employment offices redesigned job-seeking assistance programs around specific, actionable steps rather than general encouragement, discovering that participants who were asked ④to write down a concrete plan for the following week were considerably more likely to follow through than those who received only general advice. What unites these disparate interventions ⑤are a shared recognition that small, carefully tested adjustments to how choices are presented can produce measurable improvements in outcomes.

A flexitarian is someone who mainly ①eating 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 ②produces 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 ③trapping 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 ④allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a realistic first step, ⑤believing that gradual change, rather than sudden restriction, is more likely to spread widely across society.

Sociologists use the term homophily ①to describe the tendency of people to form connections with others who share similar backgrounds, opinions, or interests. This principle explains why classmates from the same major often become close friends, while coworkers with shared hobbies naturally gravitate toward one another. Because similarity reduces the effort required to understand another person's perspective, relationships ②built on shared traits tend to feel comfortable and require less negotiation. However, this same comfort can narrow the range of viewpoints someone ③encounters, since surrounding oneself with similar people limits exposure to different ideas. Social media platforms intensify this pattern through recommendation algorithms that ④suggest new friends based on shared interests or similar browsing history. As a result, users often find their online circles becoming increasingly homogeneous, filled with people who think and behave much like themselves. Recognizing this tendency ⑤allow individuals to make deliberate efforts to broaden their social networks.

Have you ever thrown away an old pair of jeans simply because they no longer fit? Instead of discarding them, many people now turn old items into something ①old and useful. This creative process, called upcycling, transforms unwanted objects into products with ②greater value than before. For example, a worn pair of jeans can be cut and sewn into a ③sturdy bag or a small pouch. Old wooden pallets, once used for shipping, are often rebuilt into ④simple furniture such as tables and shelves. However, upcycling differs from ordinary recycling, which usually breaks materials down before making something new. In upcycling, the original material keeps most of its form while gaining a fresh purpose. Therefore, choosing to upcycle rather than throw items away can reduce waste ⑤significantly.

On a summer evening, downtown streets often feel ①noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. This phenomenon, known as the urban heat island effect, occurs when cities ②retain more heat than surrounding rural areas because of their dense concentration of asphalt, concrete, and buildings. Unlike soil or vegetation, which absorb and release heat ③instantly, these man-made surfaces absorb sunlight during the day and slowly radiate it back at night, preventing temperatures from cooling. Tall buildings packed closely together also block wind, trapping warm air within narrow streets. In contrast, areas with ④abundant 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 ⑤expanding public parks, hoping that additional greenery will absorb less heat than pavement does.

I made sure to drink ①cold water instead of only cold drinks, and I began carrying a light jacket to wear indoors when the room felt too ②cold. I also started stretching and walking around every hour instead of sitting still all day, which helped me feel more ③energetic. Within a few days, my headaches ④disappeared, and I felt much more ⑤healthy.

Attention, students! Our school festival is going green this year, and we truly need your help. This event aims to reduce the disposable waste that usually piles up during the celebration. (A) First, please bring your own cup, plate, and utensils to every food booth you visit. Second, each booth should use reusable decorations rather than paper banners that get thrown away within hours. (B) If your booth needs supplies, please contact the student council office before Friday. Let us work together to create a festival that is both fun and eco-friendly. (C) Students who join as Green Helpers will manage the recycling stations, sorting cans, bottles, and paper carefully all day long. Therefore, everyone's small cooperation will directly lower the amount of trash sent to the landfill. However, single-use plastic bags are strictly prohibited at every booth this year.

주어진 문장: This process cannot happen overnight, since each stage depends on the completion of the one before it. Carbon neutrality refers to a state in which the amount of greenhouse gases a country or company releases into the atmosphere is balanced by the amount it removes, resulting in zero net emissions. ( ① ) Achieving this goal typically requires several sequential stages rather than a single sudden action. ( ② ) First, organizations attempt to reduce emissions directly by replacing fossil fuels with renewable energy sources such as solar or wind power. Next, they improve efficiency throughout their operations, minimizing the energy wasted during production and transportation. ( ③ ) Only after these direct measures have been maximized do most organizations turn to offsetting, which involves funding projects like reforestation or carbon capture to compensate for emissions that cannot yet be eliminated. ( ④ ) Critics argue, however, that some companies exploit offsetting too early, using it to avoid making genuine reductions. ( ⑤ ) Therefore, experts insist that a credible roadmap must always prioritize actual emission cuts before relying on compensation.

주어진 문장: For this reason, small differences in color or style can quickly become noticeable across the whole wall. Every spring, the art club at Sejong High School creates one large mural together instead of individual paintings. ( ① ) The process begins with a session where members suggest themes and vote on their favorite idea. ( ② ) Once a theme is chosen, the club divides into small teams, each responsible for one section of the wall. One team sketches the outline while another mixes colors to match the design. ( ③ ) Communication becomes essential at this stage, since each section must connect smoothly with the ones beside it. If one team paints too dark a shade, the whole picture can look unbalanced. ( ④ ) Therefore, members regularly step back to compare their section with the rest of the mural. ( ⑤ ) After several weekends, the teams combine their sections into a single image. The finished mural is displayed near the entrance, reminding everyone what cooperation can achieve.
