A single fertilized egg eventually ①gives rise to every cell type in the human body, from neurons to bone, a feat that has fascinated biologists for more than a century. Embryonic stem cells retain much of that original versatility, capable in principle of ②develop into almost any tissue, which is why researchers have long viewed them as a promising raw material for repairing damaged organs. Because harvesting these cells traditionally required ③destroying a human embryo, the research provoked ethical objections fierce enough to slow funding and legislation in several countries for years. A breakthrough arrived when scientists discovered that ordinary adult skin cells could be ④reprogrammed, through the introduction of a handful of specific genes, into a state resembling embryonic versatility without ever touching an embryo. These induced pluripotent cells have not entirely erased the ethical debate, but they have opened a path for stem cell research that far more scientists and funding agencies are willing ⑤to support.

Students often groan when a classic novel appears on their reading list, ①complains that the language feels old-fashioned and the plot moves too slowly. It is true that classic literature can be harder to read than a modern bestseller ②written in casual, everyday language. Yet this very difficulty is part of why classics remain valuable for young readers today. Working through unfamiliar sentence patterns and vocabulary trains the brain ③to handle complex texts, a skill that transfers directly to other subjects and to standardized tests. Beyond language training, classic novels also explore themes such as jealousy, ambition, and loss that ④have not changed much across centuries. Readers often discover that a character written hundreds of years ago struggles with feelings that still ⑤feel familiar today.

When individuals face uncertainty about how to behave, they frequently look to the actions of others for guidance, assuming that a behavior adopted by many people is more likely to be correct or appropriate than one adopted by few, a tendency known as social proof. Because conformity can substitute for independent judgment so seamlessly, individuals rarely notice when their own decisions have become ___________ rather than genuinely deliberated.

Science labs feel far safer than they actually are, largely because the equipment looks harmless and the experiments are carefully planned by a teacher. This false sense of security leads some students to skip small precautions, such as wearing safety goggles for a "simple" experiment. Chemical reactions, however, do not distinguish between a professional laboratory and a classroom; _______________. Teachers repeatedly emphasize reading each instruction before touching any material, since even a familiar-looking chemical can behave unpredictably when combined with something new.

When someone's heart suddenly stops beating, the brain begins to suffer damage within minutes unless blood keeps circulating, which is why the actions taken by an ordinary bystander before paramedics arrive can matter as much as the treatment given at the hospital. (A) Studies show that a person who receives CPR immediately from someone nearby is far more likely to survive than one who waits for professional help to arrive. (B) Despite this, many people hesitate to start chest compressions, worried that they might break a rib or make the situation worse. (C) Medical instructors respond to this fear: a cracked rib heals, but a brain deprived of oxygen for too long does not.

Anyone who has ever promised to finish a project "by Friday," only to still be working on it weeks later, has experienced the planning fallacy firsthand. (A) One proposed remedy, known as reference class forecasting, requires planners to deliberately consult outcomes from comparable past projects rather than relying solely on their own optimistic intuition. Until such external correction becomes standard practice, ambitious deadlines will likely continue to be broken with remarkable consistency. (B) This term describes the persistent tendency of individuals and organizations to underestimate how long a task will take, how much it will cost, and how many complications will inevitably arise. (C) What makes this bias particularly stubborn is that awareness of past failures rarely leads to more accurate predictions; a construction firm that finished its last three projects late will often insist, with genuine confidence, that this next project will be different. Researchers argue that planners focus almost exclusively on the specific steps of the current task while ignoring the broader statistical record of similar projects that came before.

For our club's spring project, we were told to create a sculpture using only materials collected from the school's recycling bins, and my first reaction was disappointment at not being allowed to buy proper art supplies. (A) Sorting through flattened cardboard, broken umbrella frames, and plastic bottle caps, I initially saw nothing but trash. (B) My perspective shifted once a senior member showed me a piece she had built the previous year, a bird made entirely of bent bicycle spokes and bottle caps, each cap functioning as a single feather. (C) She explained that upcycling art forces a creator to notice a material's natural shape and texture rather than simply painting over it, which often produces more original results than starting with a blank, expensive canvas.

주어진 문장: This principle applies just as powerfully outside the realm of personal finance. People often recognize, in calm reflection, that their future selves will be tempted to abandon a goal they currently value. ( ① ) Rather than relying solely on willpower at the critical moment, they may choose to restrict their own future options in advance, a strategy known as precommitment. ( ② ) 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 arisen. ( ③ ) 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 resist. ( ④ ) Similarly, someone determined to finish a project might publicly announce a deadline, transforming private intentions into a commitment that carries social consequences if broken. ( ⑤ ) What unites these examples is a simple insight: because future desires cannot always be trusted, the wisest moment to act may be now, while judgment remains clear and temptation has not yet taken hold.

In other words, wide reading does not just add facts to a student's memory; it changes the way that student questions everything else. Students who read many books across many different subjects often develop a habit that quieter learners sometimes lack: the habit of comparing new information with what they already know. ( ① ) A student who has read about ancient wars, ocean ecosystems, and modern economics can more easily notice when two different subjects share a similar pattern. ( ② ) This kind of connection-making is closely related to what psychologists call critical thinking. ( ③ ) Seeing a familiar pattern in an unfamiliar topic allows a person to ask sharper questions instead of accepting new information at face value. ( ④ ) Extensive reading also builds a large mental library of examples, which makes it easier to evaluate whether a new claim sounds reasonable or exaggerated. ( ⑤ ) Teachers often notice that widely read students argue more carefully, supporting their opinions with specific examples rather than vague generalizations. For this reason, many educators now argue that assigning a wide variety of reading material may do more for a student's thinking skills than any single course in logic.

Surveys show that fewer than half of teenage cyclists put one on before every ride. Riding a bicycle is one of the most popular ways for teenagers to get around, yet many students still skip the one piece of equipment that could save their life: the helmet. ( ① ) Some argue that a short trip to a nearby store does not require any special protection, since the risk of a serious accident feels distant and unlikely. ( ② ) However, most bicycle accidents happen close to home, on familiar streets where riders feel too comfortable to expect danger. ( ③ ) A sudden pothole, a car door opening without warning, or a patch of gravel can throw even an experienced cyclist off balance in an instant. ( ④ ) Wearing a helmet does not prevent a fall, but it dramatically reduces the chance of a serious head injury when one occurs. ( ⑤ )
