A biosensor works by pairing a biological component, such as an enzyme or antibody, with an electronic device that ①convert a biological reaction into a signal a computer can read. When the target molecule, whether glucose in blood or a trace of a pathogen, ②binds to the biological component, it triggers a small measurable change that the device translates into a readable number. This design has already transformed diabetes management, ③letting patients monitor blood sugar continuously through a small sensor worn under the skin rather than pricking a finger several times a day. Engineers are now racing to extend the same principle ④to detect subtler targets, from cancer cells circulating in the bloodstream to trace contaminants in drinking water. The central challenge is not detecting the target but doing so reliably outside a controlled laboratory, since a sensor that performs well on a clean lab bench can behave erratically once ⑤exposed to a real body or a real river.

Sociologist Erving Goffman argued that people constantly perform for others, much like actors ①managing their image on a stage, a concept known as impression management. This idea applies vividly to social media, where users select flattering photos and delete posts ②that might damage their reputation. Such careful curation allows people ③to present an idealized version of themselves that emphasizes achievements while hiding struggles or ordinary moments. However, when this performance becomes constant, a troubling gap can form between one's authentic self and the polished character ④displaying online. Maintaining that gap requires considerable emotional energy, and studies suggest it often leads to anxiety and exhaustion. Furthermore, comparing one's own carefully staged life to others' equally staged posts can distort what people believe is normal. Therefore, individuals should recognize that some self-presentation online is inevitable, but they must also protect space where imperfection ⑤is allowed to remain visible.

Time blocking is a time-management technique in which a person divides the day into fixed blocks. Each block is then assigned to a single task. Instead of relying on a loose to-do list, the person decides exactly when each task will start and end. This approach ①lowers the mental effort of deciding what to do next, since the schedule already provides the answer. It also ②limits multitasking, because each block is reserved for only one activity at a time. For instance, a student may block ninety minutes for math practice, leaving no room for messages or web browsing. Because each block has a ③vague boundary, unfinished work is ④less likely to quietly spread into the next task. Many people who adopt time blocking feel ⑤more organized throughout the day.

Last New Year's Day, I wrote three goals in my diary: reading more books, exercising regularly, and saving money for a bicycle. Today, exactly one year later, I opened that old page and ①frowned at how much had changed. I did not finish all twelve books I had planned, but I read six, which was still more than the year before. My exercise habit became the biggest ②surprise, since I now run almost every morning without feeling forced. Saving money was ③harder than I expected, since unexpected expenses kept appearing. Still, I saved enough for half of the bicycle, and I felt quite ④proud of that progress. Looking back, I realized that steady effort matters more than reaching every goal exactly as planned, and I stayed ⑤hopeful about what the next year might bring.

Many people believe that building a new habit requires strong willpower or motivation. However, psychologist BJ Fogg argues that habits form more easily when a behavior itself becomes simple to perform. His theory, called the Fogg Behavior Model, states that ___________. When motivation is low, the task must be made extremely easy, or it will not happen at all. For instance, a person who wants to exercise daily succeeds more often by committing to one push-up than to a long workout. Fogg calls this idea the law of least effort, since people naturally choose the option requiring the least energy. A student who wants to read more might leave a book open on the desk rather than setting a vague goal. By lowering the required effort, people reduce the ability barrier and make steady action far more achievable.

Emotions can spread from one person to another without a single word being spoken face to face. (A) For example, a cheerful comment posted early in a thread often encourages later commenters to write in a similarly positive tone. (B) Recently, however, psychologists have found that this same spreading effect happens even online, through text and images alone. (C) This means that a single post can shape the emotional tone of an entire online conversation.

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. (A) 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. By the end of the semester, Suji had a small group of friends who understood her sense of humor. (B) Suji signed up for the photography club, though she had never taken photography seriously before. At the first meeting, older members taught her how to adjust a camera and find a good angle. (C) Because everyone shared photos and gave friendly feedback each week, Suji gradually felt more comfortable with the other members.

Not every default setting, however, produces beneficial outcomes for the people subject to it. (A) A default that automatically enrolls customers in a costly subscription renewal, for example, can generate continued revenue for a company precisely because inertia discourages customers from canceling, even when they would prefer to stop paying. (B) This example illustrates that the power of defaults is ethically neutral in itself, capable of serving either the interests of the individual or the interests of whoever designs the choice environment. (C) Regulators in several jurisdictions have responded by requiring companies to make cancellation just as simple as enrollment, reducing the asymmetry that defaults can otherwise exploit.

Their actual forecasting accuracy, however, has repeatedly proven no better than that of far less experienced participants, and sometimes even worse. Overconfidence among financial professionals presents a puzzling contradiction. ( ① ) Fund managers and analysts typically possess years of specialized training, access to vast quantities of market data, and considerable professional experience. ( ② ) One might reasonably expect such expertise to translate into consistently superior predictions about future market movements. ( ③ ) Longitudinal studies tracking professional forecasts against actual outcomes reveal a persistent gap between confidence and accuracy. ( ④ ) This finding does not imply that expertise is worthless, but it does suggest that expertise can inflate confidence more readily than it improves genuine predictive accuracy. ( ⑤ ) Investors would therefore do well to treat confident predictions, however credentialed their source, with a healthy measure of skepticism.

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 )
