Psychologist Roy Baumeister proposed a concept ①called ego depletion theory, which suggests that willpower functions like a muscle that gradually tires after repeated use. According to this theory, every act of self-control, from resisting a snack to concentrating on difficult homework, ②draws from the same limited mental resource. As this resource becomes depleted throughout the day, later decisions ③require more effort and are more likely to fail. For instance, someone who exercises discipline avoiding distractions all morning may struggle ④to resist checking a phone by evening. Likewise, dieters report that self-control weakens sharply at night, after hours of resisting food. Some researchers argue that short breaks, adequate sleep, and blood sugar levels can help restore this depleted resource. Although later studies have questioned how strong this effect is, the theory still ⑤offer a useful framework for understanding why willpower seems to fade throughout a long day.

Smart speakers have quietly become a fixture in many households, ① responding 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 ② learning 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 ③ misunderstanding a simple request, sometimes with amusing results. Engineers continue to refine these systems, but many admit that truly natural conversation, the kind ④ that flows without repeated commands or awkward pauses, ⑤ remains one of the hardest goals in the entire field of artificial intelligence.

A documentary director named Mira first traveled to a remote Arctic glacier to film its towering cliffs of blue ice, ①<u>which seemed frozen in time</u>. ②<u>Standing before the massive wall</u>, she assumed such an enormous structure could hardly ③<u>changed</u> within a lifetime. Five years later, however, she returned to the very same coordinates, ④<u>expecting her camera to capture</u> an identical scene. Instead, she discovered that the glacier had retreated so dramatically that the ice cliffs, once visible from her original position, had nearly disappeared, leaving bare rock and pools of meltwater behind. ⑤<u>Comparing the two sets of footage side by side</u>, Mira realized that a transformation she had expected to take centuries was actually happening within a single decade. This encounter convinced her that climate change, which she had previously regarded as a distant statistic, was in fact an urgent process reshaping landscapes before her eyes.

As consumers become more aware of global social and environmental issues, many now expect companies ①to take responsibility beyond simply selling products. This expectation has given rise to ethical consumption, in which shoppers consider factors such as fair wages, humane treatment of animals, and environmental sustainability before making purchases. Companies that ignore these concerns risk public backlash, especially when unethical practices are exposed through investigative journalism or social media. Some corporations have responded by publishing detailed sustainability reports, though critics ②questions whether these documents reflect genuine change or merely serve as public relations tools. Real accountability, according to many experts, ③requires independent verification rather than self-reported claims that cannot be easily checked. Consumers, for their part, must also ④remain vigilant, since a company's marketing language does not always ⑤match its actual practices.

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 to predict what was actually said. For viewers who are deaf or hard of hearing, this improvement has quietly ② transformed everyday access to video content that once required a human transcriber and a considerable amount of time to caption properly. The system still ③ excels at overlapping speakers, strong accents, and specialized vocabulary such as medical or technical terms, occasionally producing captions that are unintentionally funny. Even with these ④ flaws, most users agree that imperfect captions are far more ⑤ useful than no captions at all.

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. 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. Shoppers use it to find where an item seen on the street can be purchased, while students use it to ① identify plants, insects, or historical artworks in seconds. 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. It is ② flawless, however; a ③ blurry photo, an unusual camera angle, or an object partly hidden behind another can easily ④ confuse the algorithm, leading to search results that have ⑤ nothing to do with the original picture at all.

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. One prominent idea suggests that dreaming helps the brain process emotional experiences, _______________. 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. Still other researchers argue that dreaming is simply a byproduct of the brain organizing memories, with vivid imagery arising as the mind sorts through the day's information rather than serving any independent purpose of its own.

The metaverse, a network of interconnected virtual worlds, has begun to generate job opportunities that did not exist just a few years ago. Meanwhile, virtual event planners organize concerts, conferences, and product launches entirely within online platforms, reaching audiences that would be impossible to gather in person. Some analysts, however, ___________, noting that the metaverse has not yet attracted the massive user base that early predictions promised. Nevertheless, major companies continue investing heavily in this technology.

When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers belonged only to a handful of government scientists. During an internship, he helped design a small satellite intended to monitor crop health from orbit, a project that combined engineering with agricultural science. He realized that ___________. After graduation, Daniel joined a startup developing lunar landing equipment, a job that barely existed when he first imagined his future career.

Researchers have long debated why people often behave so differently once they log onto the internet. (A) On the other hand, this same freedom can turn destructive when users hide behind anonymity to attack others without fear of being identified. (B) One explanation lies in the reduced sense of accountability that anonymity and physical distance create, allowing hidden emotions to surface more easily. (C) For instance, someone who feels lonely might open up honestly in an online forum, sharing feelings they would never mention to coworkers.
