As solar and wind power expand rapidly across national grids, engineers face a challenge that ①receive far less public attention than the construction of the generating facilities themselves. Unlike conventional power plants, which can adjust their output to match demand at almost any moment, solar panels and wind turbines generate electricity only when sunlight or wind is available, ②producing supply that fluctuates constantly. One proposed solution involves large-scale battery storage systems, ③which absorb surplus electricity generated during periods of high output and release it later when generation declines. Grid operators must therefore invest in infrastructure capable of ④accommodating this variability, rather than assuming renewable sources can simply replace fossil fuels without adjustment. Without such investment, integrating renewable energy could paradoxically undermine the very reliability that modern electricity grids are ⑤expected to provide.

As governments and companies work to address climate change, a new category of employment ①known as green jobs has expanded rapidly. These positions include solar panel installers, wind turbine technicians, and specialists who design energy-efficient buildings. Countries that have invested heavily in renewable energy have seen employment in this sector ②grown far faster than in the economy overall. Young workers, in particular, are drawn to green careers because they ③offer a sense of purpose alongside financial stability. Critics point out that transitioning workers from fossil fuel industries to green jobs is not always simple, ④since the required skills can differ significantly. Governments are therefore introducing training programs designed ⑤to help such workers shift smoothly into renewable energy careers.

Telemedicine, which allows patients to consult doctors through video calls rather than in-person visits, has expanded rapidly since its early ①adoption. Supporters argue that this approach saves patients considerable time and makes healthcare ②accessible to people living in remote areas without nearby hospitals. However, critics contend that virtual appointments can ③easily replace physical examinations, which remain essential for detecting certain conditions. They also worry that elderly patients unfamiliar with technology may ④struggle to access these services effectively. Despite such concerns, most healthcare experts believe telemedicine will continue to grow, ⑤complementing rather than replacing traditional in-person care.

Before making a purchase, most online shoppers now read reviews written by previous customers rather than relying solely on advertisements. These reviews, posted by people who have no financial connection to the seller, often seem more trustworthy than promotional claims. Research shows that products with a large number of positive reviews sell significantly more than those with few or no reviews at all. However, fake reviews written by paid writers or even automated programs have become a serious problem, undermining consumer trust. Platforms that fail to detect these fraudulent posts risk losing credibility with their users, who expect authentic opinions when making decisions. To address this issue, several review platforms have begun using artificial intelligence to identify suspicious patterns. Ultimately, the power of online reviews ___________.

Starting a business as a teenager comes with both benefits and difficulties. (A) On the other hand, many young entrepreneurs lack enough money or experience to grow their business quickly. (B) Because of this balance, more schools are now offering entrepreneurship clubs to support young business owners. (C) On the positive side, running even a small business teaches skills like budgeting and marketing.

Overconfidence bias is not confined to amateur investors; even seasoned financial professionals display strikingly similar patterns. (A) Fund managers surveyed about the accuracy of their own market predictions, for example, consistently rate their forecasts as more reliable than an objective analysis of their historical track record would support. (B) This gap between perceived and actual accuracy suggests that professional training and experience do not automatically immunize individuals against overconfidence. (C) Some researchers argue instead that professionals may be especially susceptible, since repeated exposure to a domain can breed a false sense of mastery over outcomes that remain fundamentally unpredictable.

Online advertising has become increasingly personalized as algorithms analyze user behavior in real time. (A) Critics, however, warn that this precision can be used to exploit psychological weaknesses rather than genuinely help consumers. (B) Supporters claim that this precision benefits users by reducing the number of irrelevant advertisements they encounter. (C) Given these opposing views, many experts call for greater transparency about how such algorithms actually operate.

The anchoring effect is not limited to shopping decisions; it also plays a subtle but powerful role in legal and financial judgments. (A) Similarly, jurors who are told that a plaintiff is seeking an unusually large sum in damages tend to award higher compensation than jurors who hear no specific figure at all, even when the evidence presented is identical. (B) This pattern suggests that anchors can distort judgments requiring careful, case-by-case reasoning, not merely quick, intuitive estimates of price. (C) For instance, experienced judges asked to set a sentence after being exposed to an arbitrary number, such as one generated by rolling dice, have been shown in experimental settings to hand down harsher sentences when the number was high.

주어진 문장: Because the videos looked completely unscripted, audiences trusted them in a way that polished commercials rarely achieve. When a beverage company launched a new flavor last summer, the marketing team faced a tight budget and needed a creative solution. ( ① ) 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. ( ② ) Within days, thousands of people began recreating the dance and tagging the brand, turning an ordinary product launch into a viral trend. ( ③ ) Because participants created the content themselves, viewers found the videos far more entertaining than a traditional advertisement would have been. ( ④ ) The company barely spent any money on production, yet the challenge reached millions of viewers across multiple platforms. ( ⑤ ) Encouraged by this success, other brands quickly attempted similar challenges, though many failed to generate the same excitement.

This is because undercooked meat, fish, and eggs can carry harmful bacteria that cause illness. Food poisoning cases increase sharply during the hot summer months, so make sure that meat, fish, and eggs are cooked thoroughly before eating. ( ① ) High temperatures allow bacteria to grow quickly in food that is not stored properly. ( ② ) To protect yourself, always wash your hands with soap before preparing food. ( ③ ) Keep perishable food in the refrigerator, and never leave it out at room temperature for more than two hours. ( ④ ) It is also wise to use separate cutting boards for raw meat and vegetables. ( ⑤ ) If you experience symptoms such as stomach pain or vomiting, seek medical help promptly.
