Many students assume that perfectionists work harder than everyone else, but psychologists describe a puzzling pattern ①called the perfectionism-procrastination cycle. This term describes how an intense fear of imperfect work ②cause people to delay starting a task rather than begin it. Because perfectionists set impossibly high standards, they often feel anxious before they even begin, and the task feels ③overwhelming. They then postpone the work to avoid ④facing their own unrealistic expectations, even though delay only increases their stress later. For example, a student writing a research paper might spend hours reorganizing notes instead of composing a single sentence that ⑤feels good enough.

Many companies now advertise themselves as environmentally responsible, yet a growing number of these claims ①turn out to be misleading. This practice, known as greenwashing, ②occurs when a business spends more effort marketing its products as eco-friendly than actually reducing environmental harm. A company might launch a recycled-packaging line while ③continuing to pollute rivers through its main factories, creating a false impression of genuine change. Such tactics deceive well-intentioned consumers who wish to shop responsibly but ④lacks the tools to verify corporate claims. In contrast, truly sustainable businesses publish detailed, independently verified data about their emissions and supply chains, ⑤allowing outsiders to check their progress.

Highlighting an awkward sentence and instantly seeing three smoother alternatives has become a routine part of writing for many students, thanks to AI writing assistants built into word processors and browsers. These tools check grammar and spelling, of course, but the more advanced versions go further, suggesting clearer phrasing, ①flagging repetitive words, and even adjusting tone to sound more formal or more casual depending on the purpose. Teachers generally ②welcome the grammar and spelling support, since it frees up class time to focus on argument and structure rather than comma placement. Concerns ③shrink, however, around the tone and phrasing suggestions, which can gradually nudge every student's writing toward a similar, polished style, making it harder to tell an individual voice from a suggestion generated by the same underlying model. Some schools have begun asking students to submit an early draft alongside the final version, specifically to ④preserve evidence of a student's own ⑤original voice.

Influencer marketing has become one of the most powerful tools that companies use to reach young consumers. Unlike traditional advertisements, which often feel distant and impersonal, posts created by influencers seem more like advice from a trusted friend. This sense of closeness, built through years of sharing daily life online, makes followers more willing to trust product recommendations than ordinary commercials. For example, a skincare brand promoted by a popular lifestyle influencer can sell out within hours simply because her audience believes her opinions are honest. However, this trust can be exploited when influencers promote products they have never actually tried. As a result, several countries now require influencers to clearly disclose paid partnerships before posting sponsored content. Consumers are becoming more cautious, checking whether reviews are sponsored before making a purchase. In the end, influencer marketing ___________.

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.

When the body fights off an infection, the immune system relies heavily on adequate sleep to function effectively. During deep sleep, the body produces and releases cytokines, proteins that help regulate immune responses and coordinate the fight against harmful invaders. People who consistently sleep fewer than six hours a night show measurably weaker antibody responses after vaccination compared with those who sleep seven or eight hours, suggesting that _______________. Chronic sleep deprivation also appears to promote low-grade inflammation throughout the body, a state that has been linked to a higher risk of heart disease. Rather than being a passive state, sleep functions as an active period during which the immune system repairs itself and prepares for future threats.

Climate change is often described as a challenge that affects the entire planet equally, yet a closer look reveals a more complicated picture. (A) Wealthy, industrialized nations have historically released the largest share of greenhouse gases while building their economies, yet developing nations, which contributed comparatively little, frequently suffer the most severe droughts and floods. This gap between responsibility and suffering raises a serious ethical question that science alone cannot answer. (B) However, the concept of climate justice reminds us that the causes and consequences of climate change are distributed unevenly across the globe. (C) For example, a farming community in a low-income country may lose its entire harvest to an unusual flood, even though its members have never owned a car or flown on a plane. Therefore, tackling climate change requires more than new technology; it demands fair policies supporting the very communities least responsible for causing the crisis.

As climate change accelerates, investors around the world are paying closer attention to how companies affect the environment and society. (A) Recently, however, many corporations have learned to boost their ESG scores without genuinely transforming their operations. Some firms publish glossy reports filled with impressive statistics while their actual carbon emissions barely decline, exploiting the fact that ESG evaluation systems still lack consistent global standards. (B) ESG management refers to a company's efforts to consider Environmental, Social, and Governance factors alongside profit when making business decisions. Investors increasingly rely on ESG ratings to judge whether a company is managed responsibly and sustainably over the long term. (C) This gap between appearance and substance has led critics to demand stricter, more transparent criteria for measuring corporate responsibility. Genuine ESG management, in contrast, requires measurable targets, independent audits, and long-term accountability rather than one-time donations or attractive slogans. Investors who wish to identify truly responsible companies should therefore examine detailed disclosures instead of trusting labels alone.

Caffeine is the most widely consumed stimulant in the world, prized for its ability to sharpen focus and fight off fatigue within minutes of consumption. (A) For this reason, many sleep specialists advise avoiding caffeine after early afternoon, since it can quietly reduce the amount of deep, restorative sleep obtained later at night. (B) It works by blocking adenosine, a chemical that gradually builds up in the brain and makes us feel increasingly sleepy the longer we stay awake. (C) The effects, however, last far longer than most people realize, since caffeine can remain active in the bloodstream for five or six hours after it is consumed.

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.
