In a classic experiment inspired by Keynes's beauty contest analogy, participants choose a number between zero and one hundred, and the winner is whoever selects the number ① farthest from two-thirds of the average of all guesses submitted. A perfectly rational player, assuming every other participant reasons with unlimited depth, would conclude the equilibrium number is zero, since reasoning about others' reasoning ② collapses the average toward that single point. In practice, however, actual guesses rarely ③ converge on zero; most participants stop reasoning after a round or two of imagining what others might guess. This gap between theoretical equilibrium and observed behavior reveals that human reasoning is ④ bounded. Economists use this game as a ⑤ diagnostic tool, since the number a person submits reveals how many levels of strategic thinking that person is willing to perform.

Every plastic product carries a small recycling mark, but few students know what these marks mean. Each symbol _______________. For instance, the number one usually stands for clear plastic bottles, while the number five represents thicker containers like yogurt cups. Reading these marks is similar to reading nutrition labels on snacks, which tell you exactly what is inside. Without checking the label, you might buy something unhealthy by mistake. Likewise, throwing plastic away without checking its mark can send a reusable item straight to a landfill. Some marks even show that a material cannot be recycled at all, so it must be sorted separately. Therefore, taking a few seconds to check the mark before throwing something away makes recycling far more effective for everyone involved.

Many teenagers check their social media accounts dozens of times a day, worried that they might miss something important happening among their friends. This anxiety, known as FOMO, or the fear of missing out, arises when people believe that others are enjoying experiences from which they themselves are excluded. For example, a student scrolling through photos of a party she was not invited to may suddenly feel a wave of loneliness and regret, even though the event has already ended. Constantly refreshing feeds to avoid missing such updates, however, makes it difficult to concentrate on schoolwork or conversations happening in the present moment. Moreover, this endless comparison with curated highlights of other people's lives tends to deepen feelings of anxiety rather than relieve them. Therefore, students should learn to ___________.

When a customer opens a company's website at midnight with a billing question, an actual employee is unlikely to be available, which is exactly the gap that customer service chatbots were built to fill. These programs can instantly answer common questions, track packages, and process simple refunds without making anyone wait on hold. Yet the technology has clear boundaries. When a customer's problem is unusual, emotionally charged, or simply does not fit the chatbot's script, _______________. Many companies have responded by designing chatbots to recognize their own limits, automatically transferring a frustrated customer to a human agent.

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.

Before a single line of dialogue is written for many animated shows, a character designer has already spent weeks deciding how that character should look, move, and be recognized at a glance. A visiting illustrator who spoke at our school explained that a truly successful design should be identifiable even as a plain black silhouette, since audiences often notice a character's outline before they notice any facial detail. She showed us early sketches of a now-famous cartoon hero, in which the same personality had been tested through dozens of different body shapes, from short and round to tall and angular, before the final version was chosen. Small choices, she added, carry surprising weight: rounded shapes tend to feel friendly and safe, while sharp angles suggest danger or power, even to viewers who have never studied design. I left the talk realizing that _______________.

Electric scooters have become a common sight on city sidewalks, offering a quick way to cover short distances, yet most riders climb on without ever putting on a helmet. (A) Part of the problem is that renting a scooter takes only a few taps on a phone screen, while finding and carrying a helmet requires planning that many riders simply skip. (B) Emergency room doctors note that scooter-related head injuries have risen sharply in recent years, closely tracking the rise in scooter popularity itself. (C) Unlike a bicycle, which typically requires balance skills built up over years of practice, an electric scooter can reach a surprising speed within seconds, often faster than new riders expect.

A single fertilized egg eventually gives rise to every cell type in the human body, from neurons to bone, a feat that has fascinated biologists for more than a century. (A) Because harvesting these cells traditionally required destroying a human embryo, the research provoked ethical objections fierce enough to slow funding and legislation in several countries for years. (B) A breakthrough arrived when scientists discovered that ordinary adult skin cells could be reprogrammed into a state resembling embryonic versatility without ever touching an embryo, opening a path for stem cell research that far more scientists and funding agencies are now willing to support. (C) Embryonic stem cells retain much of that original versatility, capable in principle of developing into almost any tissue, which is why researchers have long viewed them as a promising raw material for repairing damaged organs.

주어진 문장: Such assessments are grounded in the principle that potential harm should be identified before a project begins, rather than addressed only after damage has already occurred. Before a large-scale construction project such as a highway or dam receives government approval, planners in many countries are required to conduct an environmental impact assessment, a formal process designed to predict and evaluate the ecological consequences of a proposed development. ① This process begins with a baseline survey, in which specialists document existing conditions, including wildlife, water quality, and air composition, so that future changes can be measured against a reference point. ② Analysts then model how the project might alter these conditions, drawing on data from comparable developments. ③ For instance, a proposed highway that would bisect a forest might be evaluated for its potential to fragment habitats, disrupting migration routes on which certain species depend. ④ If the assessment identifies unacceptable risks, planners may be required to redesign the project or adopt mitigation measures such as wildlife corridors. ⑤ Critics contend, however, that assessments are sometimes treated as a bureaucratic formality rather than a genuine constraint, since developers who commission the studies retain strong influence over how the findings are interpreted. ① ② ③ ④ ⑤

**주어진 문장**: In simple terms, this process prevents carbon dioxide from ever reaching the atmosphere in the first place. As efforts to curb greenhouse gas emissions intensify, industries unable to eliminate carbon dioxide from their processes have turned to a technology known as carbon capture and storage. ① This technology involves separating carbon dioxide from the exhaust of power plants before it is released into the atmosphere, then transporting the captured gas for underground injection. ② Once injected into porous rock formations, the gas is trapped beneath layers of impermeable rock that prevent it from escaping into the air. Proponents argue that carbon capture and storage functions as a bridge technology, allowing heavy industries to keep operating while more sustainable alternatives are developed. ③ For instance, cement and steel production, both of which release carbon dioxide as an unavoidable byproduct of chemical reactions, are considered prime candidates for this approach. ④ However, critics contend that the technology remains prohibitively expensive and that building pipelines requires investments few companies make voluntarily. ⑤ Despite such concerns, many governments continue funding pilot projects, convinced that this technology will play an indispensable role in reaching emission targets. ① ② ③ ④ ⑤
