When Minji was in ninth grade, she ①posted a joking comment mocking a classmate's photo, never imagining anyone would remember it later. Three years passed, and she nearly forgot the comment ②existed, buried among hundreds of old posts. Last spring, she applied to join her school's student council, ③hoping her leadership experience would impress the selection committee. During the interview, however, one teacher mentioned ④having seen an old, unkind comment under Minji's name while reviewing applicants' profiles. She understood that digital footprints rarely disappear completely, even when the original posts ⑤was removed, because screenshots and memories often outlast the content itself.

Factories that once employed hundreds of workers on an assembly line now run with a fraction of that staff, as robotic arms handle tasks ①that used to require human hands. Economists have long debated whether this shift destroys jobs or simply ②transforms them. Historical evidence offers some comfort: previous waves of automation eventually created new categories of work that no one ③had predicted. However, critics point out that earlier transitions unfolded over generations, ④given workers time to retrain, whereas today's robots are being deployed at a pace that leaves little room for adjustment. For this reason, many economists argue that the real challenge is not the robots themselves, but the speed at which society ⑤is expected to adapt to them.

Every time a smartphone connects to a cell tower or a Wi-Fi network, it quietly records a data point that can later ①be pieced together into a detailed map of where its owner has been. Most users agree to this tracking without ②reading the fine print, assuming that a single company's database poses little threat. The real danger, however, emerges when location data from multiple sources ③combining. A pattern that reveals a person's home, workplace, and daily route can expose far more than any single app ever intended to share. Companies often argue that anonymized data cannot be traced back to individuals, yet researchers have repeatedly ④shown that a handful of location points is enough to identify a specific person. As a result, privacy experts increasingly insist that location data ⑤deserves the same legal protection as medical records.

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 ①trustworthy than promotional claims. Research shows that products with a large number of positive reviews sell significantly ②more 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, ③undermining consumer trust. Platforms that fail to detect these fraudulent posts risk ④gaining credibility with their users, who expect authentic opinions when making decisions. Ultimately, the power of online reviews depends entirely on their perceived ⑤honesty.

Melatonin is a hormone produced by a small gland deep within the brain, and its release follows a remarkably predictable daily pattern. Levels stay low throughout the bright hours of the day, begin rising in the evening as darkness falls, peak in the middle of the night, and then decline again as morning approaches. This rhythm is controlled primarily by light: specialized cells in the eye detect brightness and send signals that either permit or suppress melatonin production, which is why exposure to bright screens late at night can delay its release and make falling asleep more difficult. Unlike some hormones that directly cause the body to perform a task, _______________, preparing various systems to shift into a lower-energy state. Because of this signaling role, taking melatonin supplements at the wrong time can shift a person's internal clock in the opposite direction from what was intended.

Millions of people now wear devices that continuously track their heart rate, sleep patterns, and daily activity. Users generally assume this information belongs to them, since it is drawn directly from their own bodies. In practice, however, the terms of service that few people read often grant the manufacturer broad rights to store, analyze, and even sell anonymized versions of that data. Advocates for reform argue that biological data deserves a category of protection stronger than ordinary consumer information, precisely because _______________.

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 smiled 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 surprise, and saving money was harder than I expected since unexpected expenses kept appearing. Still, I saved enough for half of the bicycle. Looking back, I realized that ___________, and I kept trying, adjusted my methods, and learned something new about myself along the way.

Last spring, Mina joined the school environmental club because she wanted to make a difference. At first, she felt nervous about speaking in front of the other members. (A) Every Friday, the members walked around the school picking up trash near the playground. Mina soon realized that this weekly habit was like watering a small plant every day. For example, a single plastic bottle left outside could take hundreds of years to disappear. (B) However, the club leader, who had been recycling for years, welcomed her warmly. (C) Therefore, the club decided to place clear recycling bins in every classroom. In contrast to her early doubts, Mina began to feel proud of the changes she noticed. Her classmates started separating cans and paper without being reminded by teachers. By the end of the semester, Mina had become an active member.

There is also a quieter cultural cost that rarely appears in productivity reports. 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 walking the rows. ( ① ) For large operations with the capital to invest, these tools have measurably increased yields while reducing water waste. ( ② ) Smaller family farms, however, often cannot afford the upfront cost of this equipment. ( ③ ) Some worry that the gap between high-tech and traditional operations will only widen as the technology advances further. ( ④ ) Generations of farming knowledge, passed down through direct observation of soil, weather, and crops, risk being replaced by dashboards and automated alerts. ( ⑤ )

If such a divide hardens, competitive advantages in school, sports, and the workplace could come to depend less on effort than on access to capital. Beyond restoring lost function, engineers are now exploring implants and prosthetics designed to give healthy people abilities beyond ordinary human limits. ( ① ) Supporters frame this as simply the next step in a long history of human enhancement, no different in principle from eyeglasses or vaccines. ( ② ) Critics counter that earlier enhancements were broadly available to anyone regardless of wealth. ( ③ ) Cutting-edge neural and physical implants, by contrast, are likely to remain expensive for decades, potentially splitting society into those who can afford enhancement and those who cannot. ( ④ ) What began as a medical tool for restoring what was lost, in other words, may end up redefining the baseline of what counts as an ordinary human being. ( ⑤ )
