When a customer opens a company's website at midnight with a billing question, an actual employee is unlikely ①to be available, which is exactly the gap that customer service chatbots were built ②to fill. These programs can instantly answer common questions, track packages, and process simple refunds without ③making 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, the automated replies can feel frustratingly circular, ④repeating the same suggestion no matter how the question is rephrased. Many companies have responded by designing chatbots to recognize their own limits, automatically ⑤transfer a frustrated customer to a human agent before the conversation turns into a source of complaint rather than a solution.

Consider a large heap containing ten thousand grains of sand. Nearly everyone agrees that removing a single grain from such a heap leaves another heap behind; surely one grain could never make the difference between a heap and a non-heap. Yet if this principle is applied repeatedly, grain by grain, the heap eventually ②grows to a single lonely grain, or even to no grains at all, and logic alone seems to force us to accept that this final result still counts as a heap. Something has clearly ①gone wrong along the way, since no reasonable person would call one grain of sand a heap, but pinpointing exactly which single removal transformed a heap into a non-heap seems ③impossible. The puzzle exposes a deep discomfort with vague terms like "heap," "tall," or "bald," concepts that seem to admit no sharp ④boundary yet are used confidently in everyday language. Some philosophers conclude that classical logic itself may need to be ⑤revised to accommodate the genuine vagueness built into ordinary human language.

Imagine rewriting a bacterium's code the way a programmer edits a line of software, and much of what synthetic biology ①promises begins to make sense. Researchers in this field assemble standardized genetic parts into circuits that can be inserted into a cell, instructing it to perform a task that no natural organism would ②carry out. Because these circuits are built from interchangeable parts rather than designed from scratch each time, a circuit tested in one lab can often be reused, with ③minor adjustments, in an entirely different application. Critics note that biological systems ④always behave as predictably as electronic circuits, since a gene inserted into a new cell can interact with existing pathways in unexpected ways, occasionally producing results no engineer intended. Even so, as the catalog of standardized parts keeps expanding, engineers are gaining ⑤confidence to design increasingly complex systems.

Sociologist Mark Granovetter introduced an idea that seems contradictory at first glance, known as the strength of weak ties. According to this theory, people who see each other only occasionally, called weak ties, often provide more valuable information than close friends or family members, who are considered strong ties. This happens because strong ties tend to share the same social circles and, therefore, already possess similar knowledge. Weak ties, in contrast, move within different networks, which allows them to introduce ideas or opportunities that would otherwise remain unknown. For example, a former classmate rarely contacted might mention a job opening unavailable through one's immediate circle. Social media platforms have made maintaining such connections remarkably easier, letting users keep hundreds of loose acquaintances active without frequent face-to-face meetings. Consequently, these platforms _______________.

Are you curious about capturing special moments around our school? The Photography Club is now looking for new members for this semester. We meet every Wednesday afternoon in Room 204, right after regular classes end. No experience is required, since senior members always _______________. Each month, we choose a simple theme and take pictures together around the campus. At the end of the semester, we hold a small exhibition to share our favorite photos. Members are also expected to bring their own camera or smartphone to every meeting. If you enjoy taking pictures or want to try something new, please visit our booth this Friday. Feel free to ask any current member if you have questions about joining.

A small bakery once sold a basic loaf for three dollars and a premium loaf for six dollars, and most customers simply bought the cheaper one. The owner then introduced a third option: a slightly larger premium loaf priced at seven dollars, one that was 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 _______________. This pattern demonstrates that people rarely judge options in isolation; instead, they evaluate choices relative to whatever alternatives happen to be nearby.

When someone's heart suddenly stops beating, the brain begins to suffer damage within minutes unless blood keeps circulating. 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. Despite this, many people hesitate to start chest compressions, worried that they might break a rib or make the situation worse. Medical instructors respond to this fear: _______________. Modern CPR training has also been simplified, focusing on firm, rhythmic chest compressions rather than the more complicated combination of breaths and compressions once required.

Elite athletes rarely walk up to a free throw line or a golf ball without first performing a highly specific sequence of movements, a habit sports psychologists call a pre-performance routine. Far from being mere superstition, this consistent sequence serves a genuine cognitive purpose: repeating the same physical and mental steps before every attempt narrows an athlete's focus away from distracting thoughts and toward the specific technical cues needed to execute the skill correctly. Researchers have found that athletes who follow a consistent routine tend to show more stable performance under pressure than those who approach each attempt differently, because _______________. For this reason, coaches now actively teach young athletes to develop and rehearse individualized routines rather than treating them as personal quirks.

When workers receive a five percent raise in a year when prices have climbed five percent as well, their real purchasing power has not changed at all, yet many still report feeling noticeably better off. (A) Employers exploit this pattern by favoring modest nominal raises over deeper structural adjustments, since a visible increase on a payslip satisfies employees more effectively than an explanation about inflation could. (B) The illusion persists even among people who claim to understand inflation well, which suggests that the bias operates at an intuitive level that formal knowledge does not easily override. (C) This tendency to judge economic well-being by nominal figures printed on a paycheck, rather than by what that money can actually purchase, is known among economists as money illusion.

As cities have expanded across landscapes once covered with absorbent soil, impervious surfaces have turned stormwater from a resource that recharges groundwater into a hazard that floods streets and carries pollutants into waterways. (A) For example, cities that replaced pavement with permeable alternatives have reported notable reductions in flooding during storms that once overwhelmed sewers. However, engineers caution that green infrastructure cannot entirely replace conventional pipes in dense cores, where heavy runoff still requires structural reinforcement. Consequently, municipalities now regard green and gray infrastructure as complementary systems, each compensating for the other's limitations. (B) Green infrastructure, which mimics the hydrological functions that natural landscapes once performed, offers planners a way to treat the city as a sponge rather than a rigid drainage pipe. (C) Rain gardens, shallow depressions planted with deep-rooted vegetation, are designed to capture runoff from rooftops, allowing it to filter slowly through soil before reaching underground aquifers. Permeable pavement, made of porous materials that let water pass directly through, serves a similar purpose along sidewalks, where asphalt would remain impenetrable.
