People often recognize, in calm reflection, that their future selves will be tempted to ①abandoning a goal they currently value. Rather than relying solely on willpower at the critical moment, they may choose to restrict their own future options in advance, a strategy ②known as precommitment. By making certain choices costly, inconvenient, or impossible to reverse, individuals can protect a long-term goal from a short-term impulse that has not yet ③arisen. A person hoping to save money might lock funds into an account that penalizes early withdrawal, removing the very temptation that would otherwise be difficult to ④resist. Similarly, someone ⑤determined to finish a project might publicly announce a deadline, transforming private intentions into a commitment that carries social consequences if broken.

A flexitarian is someone who mainly eats plant-based meals but occasionally includes meat or fish, unlike a ①strict vegetarian who avoids animal products entirely. This flexible diet has recently ②lost attention as a practical way to fight climate change, since raising livestock produces a ③significant portion of global greenhouse gas emissions. Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at trapping heat in the atmosphere. By replacing just a few meat-based meals each week with vegetables, grains, or legumes, individuals can ④noticeably shrink their carbon footprint without giving up meat completely. Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a ⑤realistic first step, believing that gradual change, rather than sudden restriction, is more likely to spread widely across society.

Imagine standing at a crowded party where dozens of conversations blend into a wall of noise, yet you effortlessly track the words of the friend beside you. Curiously, if someone across the room utters your name, your attention snaps toward that voice almost instantly. This happens even though you had not consciously been listening to that conversation at all. This phenomenon, known as the cocktail party effect, reveals that selective attention does not simply block out every unattended sound. Early theorists such as Donald Broadbent proposed that unattended information is filtered out entirely before reaching awareness. Yet the fact that a person's own name can break through this filter contradicts such a rigid model. Anne Treisman later refined this account, suggesting that _______________. Especially meaningful stimuli, including one's own name, can still surpass the threshold of conscious recognition. This refinement suggests that attention operates less like a gate and more like a dimmer switch, adjusting the salience of competing streams of information.

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. 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. 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 _______________. 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. However, critics contend that the technology remains prohibitively expensive and that building pipelines requires investments few companies make voluntarily. Despite such concerns, many governments continue funding pilot projects, convinced that this technology will play an indispensable role in reaching emission targets.

Few ideas in policy debate provoke as much philosophical unease as the notion that a government might deliberately steer citizens toward better choices while leaving every option technically available. Defenders insist that freedom is preserved as long as no option is banned and no penalty is attached. Critics counter that this defense rests on an impoverished notion of liberty, one that ignores how _______________. The dispute ultimately turns on what freedom actually requires: the mere absence of coercion, or a decision-making process that remains transparent and undistorted.

For my birthday, my older sister took me to a small pottery studio where visitors can shape their own bowl or cup on a spinning wheel. I expected the wheel to do most of the difficult work automatically, since it was already spinning quickly by the time I sat down. My first attempt collapsed into a shapeless lump within seconds, because _______________. The instructor explained that beginners almost always press too hard on one side, which throws the entire piece off balance no matter how fast or slow the wheel spins. After nearly a dozen failed attempts, I finally produced a lopsided but recognizable cup, and the small imperfection along its rim somehow made me prouder of it than a perfectly smooth, machine-made mug ever could have. Clay, I learned that afternoon, rewards patience far more generously than it rewards force.

A plastic bag that fully decomposes within months rather than lingering for centuries sounds almost too convenient to be real, yet certain bioplastics on the market do exactly that under the right conditions. (A) Not every bioplastic biodegrades quickly, however, and some marketed as eco-friendly break down only in industrial composting facilities that reach conditions rarely found in a backyard compost heap or the open ocean. (B) Unlike conventional plastic, derived almost entirely from petroleum, many bioplastics are synthesized from renewable feedstocks such as corn starch or sugarcane, sometimes with the help of bacteria engineered to produce plastic-like polymers as a byproduct of their metabolism. (C) Critics point out that growing crops for bioplastic production can compete with food crops for farmland and water, which is why researchers are now exploring bioplastics made from agricultural waste and algae instead of dedicated crops.

Classical economic theory long assumed that decision makers gather all relevant information, calculate every possible outcome, and select the single option that maximizes their benefit. (A) Herbert Simon, however, questioned this assumption, arguing that human beings operate under real constraints of time, knowledge, and mental capacity that make such exhaustive calculation practically impossible. (B) Instead of searching endlessly for the theoretically perfect choice, people typically stop once they find an option that seems good enough to meet their immediate needs, a strategy Simon termed satisficing. (C) A shopper comparing refrigerators, for example, rarely examines every model available; she instead sets a few practical criteria, such as price and size, and selects the first appliance that satisfies them adequately. This approach is not a failure of reasoning but rather a sensible adaptation to a world where information is costly and time is genuinely limited. Consequently, models assuming unlimited rationality often fail to predict actual behavior, while frameworks acknowledging these cognitive boundaries offer a far more realistic account of how ordinary decisions are actually made.

주어진 문장: This experiment shows that consumers do not simply weigh money saved against money spent, but react to the very presence or absence of a price tag itself. Classical economic theory assumes that consumers evaluate every price change in the same rational way, weighing marginal benefit against marginal cost regardless of the absolute numbers involved. ( ① ) Behavioral economists, however, have discovered a striking exception: the moment a price drops to exactly zero, people's judgment shifts in a way that ordinary discounting cannot explain. ( ② ) In a well-known laboratory experiment, participants chose between two chocolates, one of higher quality priced at a small fee and one of lower quality offered for free. ( ③ ) When both prices were merely reduced by the same amount, most participants still preferred the higher-quality option. Yet once the cheaper chocolate's price was lowered to zero, the majority abruptly switched their preference, even though the price gap between the two options had not actually changed. ( ④ ) Researchers explain this reversal by noting that a free item carries no perceived risk of loss, which makes it feel disproportionately attractive compared with any option that still requires payment, however small. ( ⑤ )

주어진 문장: Such consistency across repeated trials suggests that the pattern is a genuine feature of human cognition, not random noise. 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 closest to two-thirds of the average of all guesses submitted. ( ① ) A perfectly rational player, assuming every other participant reasons with unlimited depth, would conclude the equilibrium number is zero, since reasoning about others' reasoning collapses the average toward that single point. ( ② ) In practice, however, actual guesses rarely converge on zero; most participants stop reasoning after a round or two of imagining what others might guess, producing average guesses that cluster between twenty and thirty-five. ( ③ ) This gap between theoretical equilibrium and observed behavior reveals that human reasoning is bounded, capable of anticipating a few steps ahead but rarely capable of iterating the process indefinitely. ( ④ ) Economists use this game as a diagnostic tool, since the number a person submits reveals how many levels of strategic thinking that person is willing to perform. ( ⑤ ) This is a measure that idealized rational agents could never provide.
