A small bakery once sold a basic loaf of bread for three dollars and a premium loaf for six dollars, and most customers, ①uncertain about the added value of the pricier option, simply bought the cheaper one. The owner then introduced a third option: a slightly larger premium loaf priced at seven dollars, one that ②were clearly inferior to the six-dollar loaf in terms of value for money. Almost nobody chose the new seven-dollar loaf, yet sales of the six-dollar loaf rose sharply, because it now ③appeared to be an obvious bargain when placed beside the inferior newcomer. This pattern, ④confirmed across countless pricing experiments in other markets, demonstrates that people rarely judge options in isolation; instead, they evaluate choices relative to whatever alternatives happen to be nearby. Businesses have since learned ⑤to design such decoys deliberately, not expecting them to be purchased at all, but hoping they will make a specific target option look far more attractive by comparison.

Bacteria have been cutting up invading viral DNA for billions of years, long before any scientist thought to borrow the trick for use in a ①laboratory. The CRISPR-Cas9 system, as it is now known, relies on a short guide RNA that ②matches a specific DNA sequence, leading a scissor-like enzyme called Cas9 directly to that exact location in the genome. Once Cas9 arrives at the target site, it ③repairs both strands of the DNA helix, and the cell's own repair machinery rushes in to mend the cut, often introducing a small change in the process. By supplying the cell with a template during this repair step, scientists can direct that machinery to ④insert a specific new sequence rather than merely disabling the original gene. What once required years of painstaking work to alter a single gene can now be accomplished within days, a shift in ⑤speed that has reshaped nearly every corner of biological research.

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.

A liver no longer has to sit inside a human body to be studied closely. By coaxing stem cells to organize themselves within a nutrient-rich gel, scientists can now grow miniature three-dimensional structures called organoids, which reproduce much of the architecture and function of a real organ. Unlike flat cultures grown on a plastic dish, organoids let cells interact in three dimensions much as they would inside the body, yielding tissue that behaves in strikingly realistic ways. This fidelity has made organoids invaluable for testing how a drug affects human tissue before any patient is exposed, _______________. Some laboratories have even grown organoids from a single patient's own cells, raising the possibility of trialing a treatment on a miniature copy of that patient's organ before committing to an actual course of therapy.

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.

Anyone who has tried to name the ink color of a word like red printed in blue letters knows how surprisingly difficult the task can feel. This everyday struggle, known as the Stroop effect, deserves more attention than casual curiosity grants it, because it reveals something fundamental about how the mind allocates its limited resources. Reading a familiar word is an automatic process practiced so extensively since childhood that it proceeds almost involuntarily, whereas naming a color requires deliberate, controlled attention. When these two processes point toward conflicting answers, _______________. Educators should not dismiss this delay as a trivial curiosity confined to laboratories, since the same competition between habit and intention underlies far more consequential situations, such as a driver's struggle to resist checking a phone despite knowing the danger. Recognizing how automatic responses can hijack conscious intentions is essential for designing environments, from classrooms to highways, that support rather than undermine our efforts at self-control.

For patients born with a single faulty gene, the disease has traditionally been treated indirectly, managing symptoms for a lifetime rather than addressing the genetic error itself. Gene therapy attempts something more ambitious: delivering a corrected copy of the gene directly into a patient's cells, often using a disabled virus as a delivery vehicle. Once inside the nucleus, the corrected gene can begin producing the protein the patient's body had always lacked, in some cases reversing symptoms that medication alone had never been able to touch. Early trials were haunted by serious setbacks, including cases in which the delivery virus triggered a dangerous immune reaction or inserted the new gene in a location that disrupted other essential genes. _______________.

Two patients diagnosed with the same disease and prescribed the same medication can respond in strikingly different ways, one recovering quickly while the other experiences little benefit or even harmful side effects. (A) This approach has proven especially valuable in cancer treatment, where tumors from two patients with the same diagnosis may carry entirely different genetic mutations that respond to entirely different drugs, though widespread adoption still faces real obstacles, since genetic sequencing remains expensive in many regions. (B) By sequencing a patient's DNA before treatment begins, doctors can increasingly predict which medication is likely to work best and at what dose, replacing a strategy once described as one-size-fits-all with something closer to a tailored fit. (C) Precision medicine starts from the observation that this variation often traces back to differences buried in each patient's genome, differences that determine how efficiently a body absorbs, breaks down, or responds to a given drug.

Social unrest does not always emerge from the poorest conditions; it frequently erupts when circumstances are improving but not quickly enough to satisfy rising expectations. (A) Political scientist Ted Gurr illustrated the pattern with what is often called the J-curve: revolutions tend to follow a period of sustained improvement that is then followed by a sudden reversal. (B) This paradox lies at the heart of relative deprivation theory, which holds that discontent arises less from objective hardship than from a perceived gap between what people expect and what they actually receive. (C) Because the theory centers on perception rather than raw statistics, it helps explain why relatively prosperous societies can experience intense protest while long-impoverished societies sometimes remain comparatively quiet.

주어진 문장: This distinction between merely sensing a stimulus and truly perceiving it matters far beyond the psychology laboratory. It would be comforting to believe that anything sufficiently large or obvious appearing within our field of vision will automatically capture our attention, yet decades of research into inattentional blindness suggest otherwise. ( ① ) When people are absorbed in a demanding task, such as counting how many times a ball is passed between players, they frequently fail to notice an unexpected and conspicuous event unfolding in plain sight, even something as unlikely as a person in a costume walking through the scene. ( ② ) This failure does not stem from a defect in the eyes, which register the stimulus perfectly well, but from the fact that conscious perception depends heavily on where attention has been directed. ( ③ ) Policymakers ought to take this finding more seriously than they currently do, because it implies that simply placing a warning sign within someone's visual range offers no guarantee that it will be consciously registered. ( ④ ) Designing safer environments, therefore, requires accounting for the limits of attention itself, not merely assuming that visibility alone ensures awareness. ( ⑤ )
