The science club at Hanul High School is running a project ①called "Grow Light." It tests how different colors of light affect plant growth. Each week, members place identical bean sprouts under red, blue, and white light and ②record their height. At first, many students expected the white light ③to produce the tallest plants. However, the results showed that plants under red light grew noticeably ④fast than the others. The club's advisor explained this by comparing light to food. Just as people need certain nutrients to grow strong, plants absorb certain colors of light more efficiently than others. To make the data reliable, students repeat each trial three times and calculate the average. They also keep a shared notebook, ⑤recording sunlight, watering time, and temperature.

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.

Sensors buried in the soil now report moisture levels in real time, drones survey entire fields for signs of disease within minutes, and automated systems adjust irrigation without a farmer ever ①walking the rows. For large operations with the capital ②to invest, these tools have measurably increased yields while reducing water waste, addressing two problems that traditional farming has struggled with for generations. Smaller family farms, however, often cannot afford the upfront cost of this equipment, and some worry that the gap between high-tech and traditional operations will only ③widen as the technology advances further. There is also a quieter cultural cost that rarely appears in productivity reports: generations of farming knowledge, passed down through direct observation of soil, weather, and crops, risk ④being replaced by dashboards and automated alerts that few young farmers ⑤teaching to question.

Many people believe that a new habit becomes automatic after only twenty-one days, but researchers who ①examined real behavior found a different number. This project, ②called the 66-day habit formation study, tracked volunteers who tried to adopt a new daily habit, like drinking water with lunch. Researchers measured how automatic each action felt over time and found that habits ③needing an average of sixty-six days to become effortless. Yet the actual time varied widely, ranging from about eighteen days for simple habits to over two hundred days for ④difficult ones. This wide range explains why the popular twenty-one-day claim, though easy ⑤to remember, rarely matches real experience.

Only a decade ago, translation apps produced sentences so ①awkward that users often laughed at the results rather than trusting them. Today, many of these apps rely on neural networks that analyze entire sentences at once, capturing context instead of translating word by word. This shift has made everyday tasks such as reading a foreign menu or chatting with an overseas friend remarkably ②chaotic. Frequent travelers now point their phone cameras at street signs and receive an ③instant translation overlaid on the screen. Even so, the technology still struggles with humor, sarcasm, and cultural nuance, areas where a single wrong word can ④completely change the intended meaning. For this reason, professional translators argue that these apps are best treated as a helpful ⑤starting point rather than a final, polished result.

Standard economic theory assumes that money is fungible, meaning that a dollar earned as salary is functionally ①identical to a dollar received as a tax refund or won in a lottery. In practice, however, people routinely sort their finances into separate mental accounts, treating money differently depending on its source or intended purpose. A household that would never dip into its retirement savings to pay for a vacation might nonetheless spend an unexpected bonus on that very trip without ②hesitation, even though both sums are, in strictly financial terms, equally available for either purpose. This ③compartmentalization can produce decisions that appear ④consistent when viewed through a purely rational lens: the same individual who diligently saves a portion of every paycheck may simultaneously carry high-interest credit card debt, effectively paying more to borrow than they earn on their savings. Mental accounting is not always harmful, however; by assigning specific categories to specific funds, individuals can also impose useful ⑤discipline on their spending, preventing money earmarked for essential needs from being diverted toward impulsive purchases.

Military researchers have developed weapons systems capable of identifying and engaging targets without a human pressing the final button. Advocates argue that autonomous systems can react faster than any human operator. Human rights organizations counter that removing a person from the final decision strips away moral responsibility, since _______________. Diplomatic negotiations toward an international treaty have repeatedly stalled, partly because military powers disagree on how to define autonomy precisely enough to regulate it.

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 _______________. 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. Because everyone shared photos and gave friendly feedback each week, Suji gradually felt more comfortable with the other members. 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.

Retailers rarely leave the shopping environment to chance. (A) For instance, cheerful background music and pleasant lighting are chosen specifically to keep shoppers relaxed and unhurried. (B) Every detail, from store layout to background music, is carefully designed to influence customer behavior. (C) As a result, customers often spend more time browsing and end up buying items they never intended to purchase.

Not all obstacles to renewable energy are technical or financial; some are psychological. (A) In contrast, switching demands research, upfront cost, and trust in unfamiliar technology, all of which can seem risky compared with doing nothing. For example, a neighborhood association might repeatedly postpone a vote on shared solar panels, not because the plan is flawed, but because members are reluctant to leave their routine. Therefore, boosting renewable adoption may depend less on proving its advantages and more on designing programs that make the first step feel easy. (B) Behavioral economists use the term status quo bias to describe a tendency to prefer the present situation over a new alternative, even when the alternative would bring greater benefits. (C) This bias helps explain why many households hesitate to switch to renewable energy, such as installing solar panels on their roofs. Although solar panels can lower electricity bills over time, homeowners often stick with their current power source because it feels safe and requires no immediate effort.
