For much of the twentieth century, memory researchers assumed that once a memory ①had been consolidated—transformed from a fragile, short-term trace into a stable, long-term representation—it remained essentially fixed, immune to further modification unless the underlying neural circuitry was physically damaged. This assumption, however, was overturned by a body of research demonstrating that the act of retrieval itself ②can destabilizing a previously consolidated memory, ③rendering it temporarily susceptible to alteration before it is, in a sense, filed away again. During this narrow window, ④which typically lasts only a few hours, the memory can be strengthened, weakened, or even subtly distorted by new information encountered in the interim, after which it must undergo a second round of stabilization, a process now widely referred to as reconsolidation. Consequently, what we experience as a stable recollection may actually be a continuously revised construction, reshaped every time it ⑤is summoned into conscious awareness and returned to storage.

Many households save far less for retirement than conventional financial advice would recommend, not necessarily because they ①lacks the resources to do so, but because a combination of procrastination, present bias, and the discomfort of forgoing current consumption repeatedly delays the decision to begin saving. Recognizing this gap between intention and action, some economists have proposed a savings program in which employees commit today to ②allocating a portion of their future salary increases toward retirement savings, rather than being asked to reduce their current take-home pay immediately. Because the sacrifice applies only to income not yet received, the commitment ③feels far less painful than an equivalent reduction in present earnings would, making employees considerably more willing to enroll. Once enrolled, the contribution rate automatically rises with each subsequent raise, ④gradually increasing savings without requiring any further deliberate action from participants. Field trials of such programs have reported substantial increases in average savings rates over several years, alongside participant satisfaction that ⑤remains notably high.

Choice architecture refers to how decisions are designed. It determines which option is automatically selected unless a person chooses otherwise, known as the default option. Research consistently shows that ___________, even when changing it takes only seconds. Organ donation is a well-known example. Countries where citizens are automatically registered as donors unless they opt out show much higher donation rates than opt-in countries. Retirement savings programs show a similar pattern, since employees automatically enrolled in a pension plan rarely cancel it. Voluntary sign-ups, in contrast, often delay indefinitely. Critics argue that default options can be manipulated to benefit companies rather than individuals, so transparency about how defaults are chosen becomes essential. Still, supporters insist that because some default must always exist, it should support people's own long-term interests rather than mere institutional convenience.

Psychologists have long studied a mechanism called the variable reward schedule, in which rewards arrive unpredictably rather than after every single action. Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. When someone posts a photo, they cannot predict exactly when likes will appear, nor how many they will eventually receive. This uncertainty triggers a small burst of dopamine each time the phone is checked, regardless of whether the result is disappointing or thrilling. Consequently, users often refresh their feeds compulsively, hoping the next check will finally bring a satisfying reward. What makes this troubling is that technology companies deliberately designed notification systems using insights borrowed from gambling research, rather than stumbling upon them by accident. Such practices raise serious ethical questions about manipulating users' brains for profit. Therefore, people must _______________.

There are a few simple strategies that make writing a personal statement easier. (A) Second, use specific examples instead of vague statements, since details make a story more convincing. (B) First, explain what each experience taught you rather than simply listing your achievements. (C) Finally, always proofread carefully, since small errors can distract readers from an otherwise strong statement.

Storing summer fruit properly can help you avoid waste and enjoy fresher flavors. (A) Berries, however, should not be washed until just before eating, because moisture encourages mold to grow. (B) Watermelon and melon should be kept in the refrigerator once they are cut, since warm air speeds up spoiling. (C) Bananas, unlike most fruit, are best kept on the counter rather than in the refrigerator.

주어진 문장: At first, she was not sure whether joining a new group would really help, but she decided to give it a try. When Suji transferred to a new school in March, she knew no one in her class and felt lonely during lunch and breaks. Her homeroom teacher suggested joining a club to make friends more easily. ① Suji signed up for the photography club, though she had never taken photography seriously before. ② At the first meeting, older members taught her how to adjust a camera and find a good angle. ③ Because everyone shared photos and gave friendly feedback each week, Suji gradually felt more comfortable with the other members. ④ One rainy afternoon, a fellow member, Hana, invited her to photograph the flooded schoolyard together. They laughed while trying to keep their cameras dry, and that moment grew into a real friendship. ⑤ By the end of the semester, Suji had a small group of friends who understood her sense of humor.

주어진 문장: This pattern echoes what happened during previous waves of industrial automation. Self-driving technology is advancing rapidly, and its impact on the transportation industry is becoming increasingly visible. ( ① ) Companies are testing autonomous trucks that can travel long distances without human drivers, potentially transforming how goods move across countries. ( ② ) At the same time, millions of professional drivers worry about losing their jobs as automation spreads through the industry. ( ③ ) Experts predict that certain driving jobs, particularly long-distance trucking, may shrink significantly within the next two decades. However, new roles are also emerging, including remote vehicle operators and technicians who maintain the complex sensors these vehicles depend on. ( ④ ) Workers who adapt their skills toward supervising and maintaining these systems are likely to find new opportunities rather than face unemployment. ( ⑤ )

주어진 문장: Faced with this uncertainty, many people begin editing their online behavior far more cautiously than before. Social media researchers use the term context collapse to describe what happens when a single online post reaches audiences that would normally remain separate in offline life. ( ① ) In daily interactions, people naturally adjust their tone and content depending on whether they are speaking with family, close friends, or professional colleagues. ( ② ) However, a typical social media feed merges these distinct audiences into one undivided crowd, since a single post can simultaneously reach parents, employers, and casual acquaintances. ( ③ ) Consequently, users often struggle to decide which version of themselves to present, knowing that a joke suitable for close friends might seem unprofessional to a supervisor. ( ④ ) For example, a party photo posted for friends could later damage someone's reputation if an employer notices it. ( ⑤ ) This tension forces many users to either self-censor heavily or maintain multiple separate accounts tailored to different audiences.

주어진 문장: This is why many people find it especially difficult to maintain healthy eating habits after a long, stressful day at work. Psychologist Roy Baumeister proposed a concept called ego depletion theory, which suggests that willpower functions like a muscle that gradually tires after repeated use. ( ① ) 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. ( ② ) As this resource becomes depleted throughout the day, later decisions require more effort and are more likely to fail. ( ③ ) 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. ( ④ ) Some researchers argue that short breaks, adequate sleep, and blood sugar levels can help restore this depleted resource. ( ⑤ ) 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.
