Opening most camera apps today reveals a row of filters that can smooth skin, brighten eyes, and reshape a jawline before a photo is even taken, all powered by AI models ① trained to recognize facial features in real time. What began as a playful novelty has become a default setting for many users, subtly ② adjusting nearly every selfie posted online. Psychologists have grown concerned about a specific consequence of this shift: people increasingly compare their unfiltered reflection in a mirror to a filtered version of themselves ③ seeing constantly on a screen, a comparison that earlier generations never had to face. Some social media platforms have responded by ④ labeling heavily edited photos or banning certain filters that alter body shape. Whether such small warnings can meaningfully counter the daily flood of filtered images, however, ⑤ remains an open question that researchers are only beginning to study.

Artificial intelligence has begun to play a surprising role in creative industries ①once thought to be uniquely human. Programs can now compose music, generate paintings, and ②draft short stories within seconds. Some artists welcome this technology, ③used AI tools to explore new styles or overcome creative blocks that once took weeks to resolve. Others, however, argue that AI-generated art lacks the emotional depth ④that comes from genuine human experience. Therefore, artists who learn to work alongside AI, rather than compete against it, may find themselves ⑤with a distinct advantage.

Communication scholar Elisabeth Noelle-Neumann proposed the spiral of silence theory to explain why certain opinions dominate public discussion while others fade into invisibility. According to this theory, individuals constantly ②observe their surrounding environment to judge which opinions are widely accepted and which are not. When people sense that their own view belongs to a minority, they often choose ③to stay silent rather than risk social isolation or criticism. This silence, however, creates a distorted impression that the minority opinion is even rarer than it actually is, ①discouraged additional supporters from speaking up. Over time, this cycle spirals downward, allowing the dominant opinion ④to appear increasingly unanimous while dissenting voices disappear from visible conversation. Social media platforms can intensify this spiral, since visibility metrics make popular opinions instantly noticeable while unpopular ones ⑤remain hidden.

Self-driving technology is advancing rapidly, and its impact on the transportation industry is becoming increasingly ①visible. Companies are testing autonomous trucks that can travel long distances without human drivers, potentially ②transforming how goods move across countries. Millions of professional drivers worry about losing their jobs as automation ③spreads through the industry. Experts predict that certain driving jobs, particularly long-distance trucking, may shrink significantly within the next two decades. However, new roles are also ④emerging, including remote vehicle operators who monitor fleets of autonomous trucks. Workers who adapt their skills toward supervising and maintaining these systems are likely to find new opportunities rather than face ⑤employment.

Every day, email providers quietly block billions of ① unwanted messages before they ever reach a user's inbox, a task that would be impossible without an AI filtering system running constantly in the background. The filter ② examines each incoming message for suspicious patterns, including certain keywords, unusual sender addresses, and formatting tricks that scammers commonly rely on to slip past detection. What makes the system effective is that it ③ stops learning after launch, since whenever a user marks a message as spam or rescues a message mistakenly filtered out, that action becomes new training data, sharpening the filter's future decisions. This creates a constant back-and-forth, since spammers study which messages get blocked and then ④ adjust their wording to slip through again. As a result, spam filtering is less like a fixed wall and more like an ⑤ ongoing contest, with each side continuously adapting to outsmart the other.

Imagine two factories making the same product: one in a country with strict carbon rules, and one in a country with almost none. The factory facing stricter rules often spends more, which can make its goods pricier than those made elsewhere. To fix this imbalance, some governments have introduced the carbon border adjustment mechanism, a policy charging imported goods a fee based on how much carbon was released while producing them. Supporters argue that the system _______________. However, critics claim it unfairly burdens developing countries, which often lack money to modernize factories quickly. For example, a small exporter in a poorer nation might struggle to pay the added charge, though it contributes little to global emissions. Still, if wealthier nations pair the policy with technical support, it could become a genuinely fair tool for cutting emissions worldwide.

When a beverage company launched a new flavor last summer, the marketing team faced a tight budget and needed a creative solution. Instead of relying on expensive television commercials, they designed a simple dance challenge and invited a handful of everyday users to post videos using the product. Within days, thousands of people began recreating the dance and tagging the brand, turning an ordinary product launch into a viral trend. The company barely spent any money on production, yet the challenge reached millions of viewers across multiple platforms. Encouraged by this success, other brands quickly attempted similar challenges, though many failed to generate the same excitement. Researchers later explained that the original challenge succeeded because it felt spontaneous and fun rather than obviously commercial. This case demonstrates that ___________.

Exercise does far more than strengthen muscles and the heart; it also produces measurable changes within the brain itself. During sustained physical activity, the body releases a protein called brain-derived neurotrophic factor, which supports the growth of new neurons and strengthens connections between existing ones, particularly in regions associated with memory and learning. Studies comparing physically active students to sedentary peers have repeatedly found that _______________, even when the exercise session ends well before the test begins. Researchers believe that exercise increases blood flow to the brain, delivering oxygen and nutrients more efficiently, while also reducing levels of stress hormones that can interfere with clear thinking.

Modern sports wearables, from wrist-worn fitness trackers to smart insoles, continuously collect data that would once have required a laboratory to measure. (A) However, the flood of data has also created a new challenge, since distinguishing a meaningful pattern from ordinary daily fluctuation requires expertise that many amateur athletes simply do not have. (B) Coaches use this constant stream of information to detect early warning signs of overtraining, sometimes noticing a decline in performance before the athlete consciously feels tired. (C) Because of this, many teams now rely on wearable data as a routine part of daily monitoring, checking it as automatically as they once checked a stopwatch.

The rapid rise of the gig economy has led researchers to examine both its opportunities and its risks. (A) In addition, because their income depends heavily on the number of tasks completed, many gig workers find it difficult to save money consistently. (B) On the positive side, gig platforms allow workers to set their own schedules and take on projects that match their skills. (C) Yet this freedom comes at a price, since most gig workers are not entitled to employer-provided benefits like health insurance.
