A growing number of health apps now track steps, sleep, and heart rate throughout the day, ① quietly building a detailed picture of a user's physical condition without requiring a single visit to a doctor's office. By comparing this stream of data against patterns drawn from millions of other users, the app's algorithm can flag early warning signs, such as an irregular heartbeat, long before the person ② experiencing it would have noticed anything unusual on their own. For people living far from specialists or unable to afford frequent checkups, this kind of constant monitoring can ③ feel like a genuine safety net. Doctors caution, however, that these apps ④ are designed to detect patterns, not to diagnose illness, and that a worried user should always confirm any alarming reading with a professional. Treating a wellness app as a substitute for medical expertise, they warn, can ⑤ being just as risky as ignoring a warning altogether.

Three-dimensional printing technology is changing how products are designed and manufactured across many industries. Unlike traditional manufacturing, which often requires expensive molds and long production times, 3D printers can create ①simple objects directly from digital files within hours. This flexibility allows companies to produce small batches of customized products without the massive costs typically associated with mass production. Hospitals now use 3D printing to create prosthetic limbs tailored ②precisely to individual patients, while automakers use it to build lightweight parts that ③reduce vehicle weight. Small businesses, too, have benefited enormously, since the technology ④lowers the barrier to entry for entrepreneurs. However, experts caution that 3D printing still struggles to ⑤match the speed of mass production for extremely large orders.

Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. This theory explains that every habit ①begins with a cue, a signal that tells the brain to start an ②automatic behavior. The brain then performs a routine, which is the action itself, whether physical or mental. Finally, the brain receives a reward, a ③negative feeling that makes it want to ④repeat the same behavior. For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run almost without ⑤conscious thought. Because this loop operates automatically, breaking a bad habit requires changing the routine while keeping the same cue and reward. Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.

Behavioral economists use the term status quo bias to describe a tendency to prefer the present situation over a new alternative, even when the alternative would bring greater benefits. This bias helps explain why many households hesitate to switch to renewable energy, such as installing solar panels on their roofs. Although solar panels can lower electricity bills over time, homeowners often stick with their current power source because it feels safe and requires no immediate effort. In contrast, switching demands research, upfront cost, and trust in unfamiliar technology, all of which can seem risky compared with doing nothing. For example, a neighborhood association might repeatedly postpone a vote on shared solar panels, not because the plan is flawed, but because members are reluctant to leave their routine. Therefore, boosting renewable adoption may depend less on proving its advantages and more on _______________.

An echo chamber refers to an online environment where people are mainly exposed to opinions that already match their own beliefs. This phenomenon occurs because social media algorithms tend to recommend content similar to what users have previously liked or shared, gradually narrowing the range of perspectives they encounter. As a result, individuals inside an echo chamber rarely engage with viewpoints that challenge their existing assumptions, which allows their original beliefs to grow increasingly extreme over time. For example, someone who frequently reads articles supporting one political party may begin to see the opposing party as entirely unreasonable, having never seriously considered its arguments. Political polarization, a significant issue in many countries today, is often linked to this pattern of selective exposure. Breaking out of an echo chamber requires ___________.

Advertisements often rely on subtle psychological techniques that persuade viewers without their conscious awareness. One common method, known as social proof, shows images of many people using or enjoying a product, suggesting that its popularity guarantees quality. Another technique appeals to authority, featuring experts or professionals endorsing a product to make it seem more credible and trustworthy. Emotional appeals are equally common, connecting products with feelings such as happiness, nostalgia, or belonging rather than focusing on practical features. Repetition also plays a significant role, since seeing the same advertisement multiple times increases familiarity, which people often mistake for reliability. Researchers studying consumer behavior have found that ___________, since awareness disrupts the automatic psychological response advertisers depend on.

The subscription economy has changed the way many people think about ownership. (A) As a result, companies can predict their income more accurately and plan their operations accordingly. (B) Rather than buying products outright, consumers increasingly prefer paying small recurring fees for continued access. (C) This shift benefits businesses as well, since steady monthly payments create a stable source of revenue.

Caffeine is the most widely consumed stimulant in the world, prized for its ability to sharpen focus and fight off fatigue within minutes of consumption. (A) For this reason, many sleep specialists advise avoiding caffeine after early afternoon, since it can quietly reduce the amount of deep, restorative sleep obtained later at night. (B) It works by blocking adenosine, a chemical that gradually builds up in the brain and makes us feel increasingly sleepy the longer we stay awake. (C) The effects, however, last far longer than most people realize, since caffeine can remain active in the bloodstream for five or six hours after it is consumed.

주어진 문장: This is why productivity coaches often recommend starting with just one or two blocks per day rather than filling the entire schedule at once. Time blocking is a time-management technique in which a person divides the day into fixed blocks. Each block is then assigned to a single task. ( ① ) Instead of relying on a loose to-do list, the person decides exactly when each task will start and end. ( ② ) This approach lowers the mental effort of deciding what to do next, since the schedule already provides the answer. ( ③ ) It also limits multitasking, because each block is reserved for only one activity at a time. ( ④ ) For instance, a student may block ninety minutes for math practice, leaving no room for messages or web browsing, while another student may reserve an evening block solely for vocabulary review. Because each block has a clear boundary, unfinished work is less likely to quietly spread into the next task. Many people who adopt time blocking feel more organized throughout the day. ( ⑤ )

Shoppers use it to find where an item seen on the street can be purchased, while students use it to identify plants, insects, or historical artworks in seconds. Instead of typing keywords into a search bar, a growing number of people now simply upload a photo and let an algorithm figure out what it contains. ( ① ) This process, known as reverse image search, compares the visual patterns in a picture against a massive database, identifying everything from a landmark in the background to the exact model of a pair of sneakers. ( ② ) The system works by breaking an image down into countless small features, such as edges, colors, and shapes, then matching that pattern against millions of stored examples. ( ③ ) It is not flawless, however. ( ④ ) A blurry photo, an unusual camera angle, or an object partly hidden behind another can easily confuse the algorithm, leading to search results that have nothing to do with the original picture at all. ( ⑤ )
