On the first day of winter break, my friend Yuna and I sat in a cafe and talked about the new year ahead. Instead of ①making separate plans, we decided to write our goals together on one sheet of paper. Yuna wanted ②improving her English speaking, while I wanted to wake up earlier every morning. We agreed ③to text each other every night to report what we had done that day. Yuna, ④who noticed my short replies, called me instead of just texting. Because we supported each other through difficult moments, both of us ⑤successfully reached our goals by spring.

As a result, the ads that appear on a person's screen often feel remarkably ①specific, sometimes referencing items browsed only minutes earlier. Supporters argue that this level of precision benefits consumers by ②reducing exposure to irrelevant advertisements and highlighting products they genuinely need. Some researchers have found that people who see highly personalized advertisements make impulsive purchases ③less frequently than those who see generic ones. Because these algorithms operate largely without public oversight, few consumers fully understand how their personal data shapes what they eventually buy. Greater ④transparency, many experts argue, would allow consumers to make more ⑤informed decisions about their own online behavior.

Three-dimensional printing technology is changing how products are designed and manufactured across many industries. Unlike traditional manufacturing, which often requires expensive molds and long production times, 3D printers can create ①simple objects directly from digital files within hours. This flexibility allows companies to produce small batches of customized products without the massive costs typically associated with mass production. Hospitals now use 3D printing to create prosthetic limbs tailored ②precisely to individual patients, while automakers use it to build lightweight parts that ③reduce vehicle weight. Small businesses, too, have benefited enormously, since the technology ④lowers the barrier to entry for entrepreneurs. However, experts caution that 3D printing still struggles to ⑤match the speed of mass production for extremely large orders.

Long before humans learned to drill for oil, microorganisms had already ① mastered the art of converting sunlight and carbon dioxide into stored chemical energy. Modern biofuel research borrows this ability, cultivating algae or engineered bacteria in large tanks where they can be coaxed into producing oils and sugars that can be ② refined into fuel usable in existing engines. Unlike crops grown for corn-based ethanol, which ③ compete directly with food production for arable land, many algae strains can thrive in shallow ponds, wastewater, or even coastal seawater unsuitable for conventional agriculture. Engineers have also learned to tinker with the metabolic pathways of these organisms, boosting oil yield far beyond what any wild strain would naturally produce on its own. Despite this progress, producing biofuel at a cost competitive with fossil fuel remains ④ difficult, since harvesting and processing the organisms ⑤ conserves a substantial share of the energy the fuel itself will eventually provide.

Have you ever thrown away an old pair of jeans simply because they no longer fit? Instead of discarding them, many people now turn old items into something new and useful. This creative process, called upcycling, transforms unwanted objects into products with greater value than before. For example, a worn pair of jeans can be cut and sewn into a sturdy bag or a small pouch. Old wooden pallets, once used for shipping, are often rebuilt into simple furniture such as tables and shelves. However, upcycling differs from ordinary recycling, which usually breaks materials down before making something new. In upcycling, the original material keeps most of its form while gaining a fresh purpose. Therefore, choosing to upcycle rather than throw items away can reduce waste significantly. _______________.

This dopamine-driven cycle explains why so many people check their phones dozens of times throughout the day without even realizing it. (A) Neuroscientists have found that the anticipation of a possible reward, not the reward itself, produces the strongest dopamine response in the brain. (B) In other words, the brief moment of waiting to see how many likes a post receives can feel more exciting than the actual number that appears. (C) Because this anticipation is so powerful, technology designers intentionally build delays and randomness into how notifications are delivered.

Dear members of the Debate Club, I am writing to let you know that our regular meeting time has been changed. (A) Please bring the debate topic that you prepared last week, since we will practice our arguments together. If you cannot attend the new meeting time, please reply to this email by Tuesday evening. (B) We usually meet in Room 304 every Wednesday after school, but the room will be used for sports day practice next week. Instead, our meeting will be held in the library on Thursday at the same time. (C) We also need two volunteers to arrange the chairs and tables before the meeting begins. Mr. Park, our club advisor, will join us this time to give feedback on our speaking skills. Thank you for your understanding, and I look forward to seeing everyone on Thursday.

주어진 문장: The sudden attention was overwhelming, but it also opened doors she had never imagined. Soojin started posting short cooking videos on her phone during her last year of high school, never imagining it could become a career. ( ① ) At first, only a handful of friends watched her clips, and she nearly quit after several months without noticeable growth. ( ② ) She kept experimenting, however, adjusting her editing style and posting more consistently despite the discouraging numbers. Everything changed when one video demonstrating a simple recipe unexpectedly reached millions of viewers overnight. ( ③ ) Brands began contacting her, offering payment in exchange for featuring their products in future videos. ( ④ ) Within a year, Soojin was earning more from her online content than most entry-level jobs would have paid her. ( ⑤ ) Still, she quickly learned that being a creator demanded constant work, since algorithms rewarded frequent uploads and audiences expected fresh content daily.

주어진 문장: Not everyone, however, feels this financial burden equally, since household circumstances vary widely. The term green premium describes the extra cost that consumers must pay when they choose an environmentally friendly product or energy source over a conventional, cheaper alternative. ( ① ) For example, an electric vehicle or solar-powered appliance often carries a higher price tag than its gasoline-powered or coal-based counterpart, even though it produces fewer emissions over time. ( ② ) This price gap frequently discourages shoppers who support sustainability in principle but cannot justify the additional expense within a limited household budget. ( ③ ) In contrast, wealthier consumers can absorb the premium more easily, which creates unequal participation in green markets. ( ④ ) To narrow this gap, governments have introduced subsidies and tax credits that lower upfront costs, while companies invest in research to make clean technologies cheaper to manufacture. ( ⑤ ) As production scales up and innovation continues, many economists expect the green premium to shrink steadily, eventually making sustainable choices the more affordable option for most consumers.

This is a decision, in short, that no single person should be allowed to make alone. The discovery of CRISPR gene-editing technology gave scientists a tool precise enough to correct a single mistaken letter in the human genome, raising hope for curing inherited diseases that have resisted treatment for generations. ( ① ) Yet the same precision that makes CRISPR so promising also makes it dangerous in the wrong hands. ( ② ) Editing a gene in a sperm, egg, or early embryo does not simply change one patient. ( ③ ) It alters the genetic code passed down to every future generation. ( ④ ) Scientific organizations around the world have therefore drawn a careful line, permitting gene editing to treat disease in existing patients while banning any edit that would be inherited by their descendants. ( ⑤ ) Critics worry, however, that this line will become harder to enforce than it is to draw.
