Self-driving technology is advancing rapidly, and its impact on the transportation industry ①is becoming increasingly visible. Companies are testing autonomous trucks ②that can travel long distances without human drivers, potentially transforming how goods move across countries. Millions of professional drivers worry about ③lose their jobs as automation spreads through the industry. Experts predict that certain driving jobs, particularly long-distance trucking, may ④shrink significantly within the next two decades. New roles are also emerging, including remote vehicle operators who monitor fleets of autonomous trucks and technicians ⑤who maintain the complex sensors these vehicles depend on.

As companies collect enormous amounts of personal data to improve their products and target advertisements, serious ethical questions ①have emerged about how that information should be handled. Employees who work with big data now face responsibilities ②that previous generations rarely encountered, since a single careless decision can expose millions of people's private information. Some argue that strict regulations should govern data collection, even if such rules ③slow innovation and increase costs for businesses. Others insist that self-regulation within companies, guided by clear ethical training, can ④protects consumers just as effectively without stifling progress. Universities have begun adding data ethics courses to computer science programs, ⑤recognizing that future employees will need to balance innovation with responsibility.

Climate scientists frequently warn about tipping points, thresholds beyond which a small additional change ①triggers a large, often irreversible shift in the climate system. Unlike gradual warming, which unfolds steadily over decades, crossing a tipping point can produce dramatic consequences within a short period. For instance, as Arctic ice melts, it exposes darker ocean water that ②absorb more sunlight than reflective ice, accelerating further melting in a self-reinforcing cycle. Similarly, scientists worry that a major ocean current, which currently ③redistributes heat across the planet, could slow dramatically if enough freshwater from melting glaciers dilutes the surrounding seawater. Once such thresholds are crossed, ④restoring the original balance may become nearly impossible, even if emissions are later reduced. Therefore, researchers argue that preventing these transitions ⑤matters more than merely slowing average temperature increases.

Limited-edition products are goods that are released in small quantities for a ①short period of time. Many companies use this strategy because scarcity naturally ②decreases how much people desire an item. When consumers believe that a product will disappear soon, they often feel ③pressured to buy it immediately rather than wait. This excitement is ④intensified by social media, where people proudly share photos of items that others could not obtain. As a result, some shoppers later ⑤regret spending money on products they rarely use afterward.

Psychologist Roy Baumeister proposed a concept called ego depletion theory, which suggests that ___________. According to this theory, every act of self-control, from resisting a snack to concentrating on difficult homework, draws from the same limited mental resource. As this resource becomes depleted throughout the day, later decisions require more effort and are more likely to fail. For instance, someone who exercises discipline avoiding distractions all morning may struggle to 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 offers a useful framework for understanding why willpower seems to fade throughout a long day.

Generation Z, typically defined as those born between the late 1990s and early 2010s, approaches shopping quite differently from previous generations. Having grown up with smartphones and social media, they research products extensively online before making even small purchases. Unlike older generations, who often valued brand loyalty above all else, many members of Generation Z prioritize a company's values, switching brands easily if one no longer matches their beliefs. They also tend to favor secondhand and resale platforms, viewing sustainability as an important factor rather than an afterthought. Peer recommendations shared through short videos frequently carry more weight than traditional celebrity endorsements. Businesses that fail to adapt to these preferences risk losing an entire generation of potential customers. Consequently, many companies now ___________.

Across many countries, high schools begin classes early in the morning, often before eight o'clock. This schedule assumes that teenagers can simply go to bed earlier to compensate, but biology tells a different story. During adolescence, the body's internal clock shifts later, delaying the release of melatonin until well after ten at night. As a result, most teenagers are not physiologically ready to fall asleep until much later than younger children or adults. When early start times force them to wake before their bodies have completed a full sleep cycle, the mismatch accumulates into a chronic sleep debt that affects concentration and mood throughout the school day. Researchers who study this mismatch argue that _______________. Some school districts that delayed their start times by thirty minutes reported improvements in attendance, suggesting that the timing of the school day matters more than commonly assumed.

A growing number of health apps now track steps, sleep, and heart rate throughout the day, quietly building a detailed picture of a user's physical condition. 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 experiencing it would have noticed anything unusual. Doctors caution, however, that these apps are designed to detect patterns, not to diagnose illness, and that _______________.

3D printing has found practical applications across a surprisingly wide range of fields. (A) In medicine, for example, hospitals now create prosthetic limbs that are precisely tailored to each patient's body. (B) The automotive industry has also adopted the technology, using it to manufacture lightweight parts that improve fuel efficiency. (C) Even small businesses have gained access to manufacturing capabilities that were once available only to large corporations with significant capital.

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. Every day, email providers quietly block billions of 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. ( ① ) The filter 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. ( ② ) What makes the system effective is that it keeps learning after launch. ( ③ ) This creates a constant back-and-forth, since spammers study which messages get blocked and then adjust their wording to slip through again. ( ④ ) As a result, spam filtering is less like a fixed wall and more like an ongoing contest, with each side continuously adapting to outsmart the other. ( ⑤ )
