Internet activist Eli Pariser introduced the term filter bubble to describe a phenomenon ①created by online algorithms. Social media platforms and search engines constantly track which links users click and how long they linger on certain posts. Based on this data, algorithms predict what each individual is most likely ②to enjoy and quietly prioritize similar content in future results. As a result, two people who type the same search query can receive strikingly different results, each ③tailoring to personal history. This automatic filtering happens silently, without users ever ④deciding to limit what they see. Consequently, many people gradually lose access to viewpoints ⑤that challenge their existing beliefs, even though they never intended to avoid them.

Browsing an online store today often means ① chatting with an AI assistant that asks a few quick questions, such as budget or intended use, before suggesting a short list of products tailored to the answers. Unlike a static list of best-sellers, this assistant can adjust its suggestions on the spot, ② responding to follow-up questions the way a knowledgeable salesperson might in a physical store. Retailers report that shoppers ③ who use these chatbots tend to complete purchases more often and return fewer items, since the guided conversation helps buyers choose products that actually fit their needs. Some shoppers, however, remain wary of how personal the questions can feel, ④ wonder how much of that conversation is quietly stored and reused to influence future purchases. Consumer advocates argue that stores should clearly explain what happens to this data, rather than ⑤ burying the explanation in a lengthy privacy policy.

Turning on automatic captions used to mean settling for garbled text full of obvious errors, but recent speech-recognition models have made same-language captions ① accurate enough that many viewers now leave them on by default, even when watching content in their native language. The technology listens to audio, breaks it into individual sounds, and matches those sounds against a massive library of words and phrases ② to predict what was actually said. For viewers who are deaf or hard of hearing, this improvement has quietly ③ transformed everyday access to video content that once required a human transcriber. The system still stumbles over overlapping speakers, strong accents, and specialized vocabulary, ④ occasionally producing captions that are unintentionally funny. Even with these flaws, most users agree that imperfect captions ⑤ is far more useful than no captions at all.

Last January, Minji wrote the same resolution she always wrote: study English for an hour every day. By February, she had already ①quit, just as in previous years. Frustrated, she asked her teacher why her willpower always failed, and learned about a concept ②called implementation intentions. Instead of vaguely intending to study more, Minji made a precise plan: if she finished dinner, then she would study for thirty minutes. She also ③prepared a backup plan: if she felt too tired, then she would study for just ten minutes instead of skipping entirely. Because these plans removed the need to decide anything in the moment, starting became ④far more easily for Minji. By December, she had studied for eleven straight months, ⑤proving that clear if-then plans beat vague intentions.

The subscription economy refers to a business model ①in which consumers pay a recurring fee to access goods or services rather than owning them outright. One major reason for this growth is convenience, since subscribers no longer need ②to make repeated purchasing decisions once they sign up. Another reason is that companies benefit from predictable revenue, ③what allows them to plan production and marketing more efficiently than with one-time sales. For example, a monthly clothing subscription delivers new outfits automatically, ④saving customers the time and effort of shopping in stores. However, some critics argue that subscriptions encourage people ⑤to pay for services they barely use.

Insomnia is ① rarely caused by a single factor; it usually emerges from an interaction between psychological stress and physiological arousal that keeps the body from settling into sleep. A common trigger is what researchers call cognitive hyperarousal, in which the mind continues to race with worries about work, relationships, or even the inability to sleep itself, creating a frustrating cycle where anxiety about insomnia becomes a cause of insomnia. At the same time, the body's stress response system can become ② chronically activated, releasing hormones such as cortisol that keep heart rate and body temperature ③ depressed at night, both of which interfere with the natural drop in arousal needed to fall asleep. Poor sleep habits, including irregular bedtimes and excessive screen use before bed, can further ④ weaken the body's internal signals for sleep onset. Because these psychological and physiological factors ⑤ reinforce one another, effective treatment for chronic insomnia addresses both the racing mind and the underlying pattern of physical tension, rather than relying on medication alone.

Caffeine is the most widely consumed stimulant in the world, prized for its ability to ① sharpen focus and fight off fatigue within minutes of consumption. It works by blocking adenosine, a chemical that gradually builds up in the brain throughout the day and makes us feel ② decreasingly sleepy the longer we stay awake. By occupying the receptors that adenosine would normally bind to, caffeine tricks the brain into feeling alert even when the body has accumulated significant sleep pressure. The effects, however, last far longer than most people realize. Because caffeine can remain active in the bloodstream for five to six hours, a cup of coffee consumed in the late afternoon may still be ③ interfering with the ability to fall asleep at midnight. Even when people do not consciously notice difficulty falling asleep, caffeine has been shown to ④ reduce the amount of deep, restorative sleep obtained later in the night. For this reason, many sleep specialists advise ⑤ avoiding caffeine after early afternoon.

On a summer evening, downtown streets often feel noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. This phenomenon, known as the urban heat island effect, occurs when _______________. Unlike soil or vegetation, which absorb and release heat gradually, these man-made surfaces absorb sunlight during the day and slowly radiate it back at night, preventing temperatures from cooling. Tall buildings packed closely together also block wind, trapping warm air within narrow streets. In contrast, areas with abundant trees and open water naturally stay cooler, since plants release moisture that helps lower surrounding temperatures. To reduce this effect, many cities have begun installing rooftop gardens and expanding public parks, hoping that additional greenery will absorb less heat than pavement does.

When the body fights off an infection, the immune system relies heavily on adequate sleep to function effectively. During deep sleep, the body produces and releases cytokines, proteins that help regulate immune responses and coordinate the fight against harmful invaders. People who consistently sleep fewer than six hours a night show measurably weaker antibody responses after vaccination compared with those who sleep seven or eight hours, suggesting that _______________. Chronic sleep deprivation also appears to promote low-grade inflammation throughout the body, a state that has been linked to a higher risk of heart disease. Rather than being a passive state, sleep functions as an active period during which the immune system repairs itself and prepares for future threats.

주어진 문장: Vague intentions, by contrast, give the brain no clear signal about when effort should begin or end. Setting a goal such as 'I will study harder' rarely leads to meaningful improvement. ( ① ) According to psychologists Edwin Locke and Gary Latham, specific and challenging goals produce far better performance than vague or easy ones. ( ② ) This idea, known as goal-setting theory, suggests that clear targets direct attention and sustain effort over time. ( ③ ) To apply this theory effectively, many educators recommend the SMART framework, which requires goals to be Specific, Measurable, Achievable, Relevant, and Time-bound. ( ④ ) For instance, a student following this framework might say, 'I will memorize thirty new words every week for two months.' Because the goal includes a clear number and a deadline, progress becomes easy to track and evaluate. Challenging goals also tend to increase motivation, since people often work harder when a target feels meaningfully difficult rather than trivially simple. ( ⑤ )
