문제 1

Smart speakers have quietly become a fixture in many households, ①responding to spoken requests for weather updates, music, or kitchen timers. Behind this simple exchange lies a complex process: the device converts sound waves into text, interprets the meaning using language models, and then generates a spoken reply, all within a second or two. Because these assistants improve by ②learning from millions of interactions, they gradually become better at recognizing regional accents and casual phrasing that once confused them. Still, the technology remains far from perfect. Background noise, overlapping voices, or an unusual sentence structure can cause the assistant ③misunderstanding a simple request, sometimes with amusing results. Engineers continue to refine these systems, but many admit that truly natural conversation, the kind ④that flows without repeated commands or awkward pauses, ⑤remains one of the hardest goals in the entire field of artificial intelligence.

문제 2

In recent years, mental health experts have identified a distinct emotional response to environmental crisis, commonly called eco-anxiety. Eco-anxiety describes persistent worry, grief, or fear triggered by awareness of climate change and its consequences for the future. Although people of all ages can experience it, teenagers and young adults seem especially ①immune, since they anticipate living through decades of worsening conditions. Common symptoms include difficulty sleeping, a sense of ②hopelessness, and guilt over ordinary choices such as travel or diet. For example, some students report feeling ③paralyzed whenever they read alarming climate news, unable to focus on schoolwork or hobbies. However, experts emphasize that eco-anxiety is not a disorder to be eliminated but a ④natural reaction that can be channeled productively. Rather than avoiding the topic, young people are encouraged to join community projects, since taking constructive action tends to ⑤restore a sense of control and ease overwhelming distress.

문제 3

On a summer evening, downtown streets often feel ①noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. This phenomenon, known as the urban heat island effect, occurs when cities ②retain more heat than surrounding rural areas because of their dense concentration of asphalt, concrete, and buildings. Unlike soil or vegetation, which absorb and release heat ③instantly, 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 ④abundant 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 ⑤expanding public parks, hoping that additional greenery will absorb less heat than pavement does.

문제 4

Browsing an online store today often means chatting with an AI assistant that asks a few quick questions, such as budget or intended use, before suggesting a short list of products ①tailored to the answers. Unlike a static list of best-sellers, this assistant can adjust its suggestions on the spot, responding to follow-up questions the way a knowledgeable salesperson might in a physical store. Retailers report that shoppers who use these chatbots tend to ②complete purchases more often and return fewer items, since the guided conversation helps buyers choose products that actually fit their needs. Some shoppers, however, remain ③confident about how personal the questions can feel, wondering how much of that conversation is quietly stored and reused to influence future purchases. Consumer advocates argue that stores should ④clearly explain what happens to this data, rather than ⑤burying the explanation in a lengthy privacy policy that almost no one reads.

문제 5

When people encounter ①solid scientific evidence about climate change, we might expect them to accept it without hesitation. However, many individuals still ②dismiss or downplay such evidence, and psychologists explain this pattern through a concept called motivated reasoning. Motivated reasoning refers to the tendency to process information in a way that protects one's existing beliefs, identity, or lifestyle rather than to pursue objective truth. For example, a person whose livelihood depends on the fossil fuel industry may ③unconsciously search for reasons to doubt climate data, even while claiming to value scientific accuracy. This happens because accepting uncomfortable facts can ④protect a person's sense of self or demand costly lifestyle changes. Therefore, simply presenting more data ⑤rarely persuades a committed skeptic. Instead, experts suggest connecting climate information to values the person already holds, such as family safety or economic stability, so that acceptance feels natural rather than threatening.

문제 6

Sleep apnea is a disorder in which breathing repeatedly stops and restarts during sleep, often because the muscles at the back of the throat ①relax too much and block the airway. Each pause can last from a few seconds to over a minute, and it may occur dozens of times in a single night without the sleeper ever ②waking up fully. Because these interruptions rarely produce a clear memory the next morning, many people remain ③unaware that anything is wrong, even as chronic fatigue, headaches, and irritability build up over months. Doctors therefore rely less on a patient's own account of the night and more on ④subjective measurements, such as overnight oxygen levels and airflow patterns recorded in a sleep laboratory. Left untreated, the disorder has been linked to serious long-term risks, including high blood pressure and heart disease, which makes an accurate diagnosis far more ⑤urgent than its subtle nighttime symptoms might suggest.

문제 7

Mira grew up in a small village where fishing and farming had sustained her family for generations. (A) International organizations, however, still struggle to agree on how to protect people like her, since climate migrants are not officially recognized as refugees under current law. (B) Mira missed her old house terribly, yet she slowly began to build a new life in the crowded city, learning to adapt just as her ancestors once had. (C) When the sea finally swallowed the rice paddies that had fed her village for generations, her parents decided that staying was no longer possible. Together with many neighbors, they packed what little they could carry and moved inland, becoming what experts now call climate migrants, people forced to abandon their homes because of rising seas, droughts, or other disasters. This term, rarely used a decade ago, has become increasingly common as extreme weather displaces communities worldwide.

문제 8

When the body fights off an infection, the immune system relies heavily on adequate sleep to function effectively. (A) Rather than being a passive state in which the body simply rests, sleep functions as an active period during which the immune system repairs itself and prepares for future threats, which is why doctors often recommend extra sleep when someone is fighting an illness. (B) 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 and other chronic conditions. (C) During deep sleep, the body produces and releases cytokines, proteins that help regulate immune responses, and people who consistently sleep fewer than six hours a night show measurably weaker antibody responses after vaccination.

문제 9

For centuries, dreams have fascinated scientists and philosophers alike, yet no single theory fully explains why the sleeping brain generates such vivid and often bizarre experiences. (A) Another theory proposes that dreams serve a more practical function, allowing the brain to rehearse responses to threats without any real danger, a kind of nightly simulation that may have offered early humans a survival advantage. (B) Still other researchers argue that dreaming is simply a byproduct of the brain organizing memories rather than serving any independent purpose, and because these theories rest on indirect evidence, none has been conclusively proven, leading many scientists to suspect that dreaming may serve several functions simultaneously. (C) One prominent idea suggests that dreaming helps the brain process emotional experiences, replaying difficult events in a safe, low-stakes environment so that their emotional intensity gradually fades.

문제 10

In the days leading up to an endurance event, many athletes deliberately increase their carbohydrate intake while reducing training volume, a practice known as carbohydrate loading. (A) Because glycogen serves as the primary fuel source during prolonged, intense exercise, entering an event with fuller stores can delay the point of exhaustion that runners often call hitting the wall. (B) Sports nutritionists caution, however, that the timing and composition of meals matter as much as the total quantity of carbohydrate consumed. (C) The strategy is designed to maximize the amount of glycogen, the storage form of carbohydrate, packed into muscle tissue before competition begins.
