Online advertising algorithms analyze enormous amounts of user data ①to determine which products a person is most likely to purchase. Every click, search, and pause while scrolling provides information that these systems use ②to refine future advertisements. Supporters argue that this level of precision benefits consumers by ③reducing exposure to irrelevant advertisements and highlighting products they genuinely need. Critics, however, worry that constant exposure to tailored ads can encourage unnecessary spending, since algorithms ④is specifically designed to identify and exploit individual weaknesses. Greater transparency, many experts argue, would allow consumers ⑤to make more informed decisions about their own online behavior.

Social psychologists describe a phenomenon called the bystander effect, in which individuals become less likely ①helping a victim as the number of witnesses increases. Each observer assumes someone else will step in, and this diffusion of responsibility leaves no one ②willing to act. Cyberbullying magnifies this problem, since a single humiliating post can be witnessed by thousands of people ③scattered across the internet rather than a few standing nearby. Anonymity intensifies the effect further, allowing silent observers ④to scroll past cruel comments without feeling accountable for their inaction. Some bystanders even worry that intervening publicly might make them the bully's next target, so they choose ⑤to remain silent instead.

Every July, our school library launches a summer reading challenge that invites students to read at least five books before classes begin again in September. Students who complete the challenge receive a ① small prize, but many say the real reward is something else entirely. Without daily homework and tests to worry about, summer gives students ② rare freedom to choose books purely because they sound interesting, not because a teacher assigned them. Librarians notice that students often pick more ③ common genres during the challenge, including graphic novels, poetry, and nonfiction about hobbies they enjoy. This freedom seems to ④ matter more than the prize itself, since students who only cared about winning tend to quit once the reading feels difficult, while curious readers keep going. Teachers who track student progress after summer report that challenge participants often return in September with noticeably ⑤ stronger reading habits than classmates who read nothing over the break.

When summer vacation began, I decided to make a daily schedule so that I would not waste my free time. At first, my plan was too ①strict, with study sessions packed back to back and almost no breaks. After only three days, I felt exhausted and gave up on the schedule completely. My older sister recommended setting two or three main goals for each day rather than filling every single hour, which sounded much more ②relaxed. I also learned to include short breaks between tasks, since resting actually ③helps me focus better afterward. Since making these changes, I have been able to follow my schedule much more ④consistently, and my vacation has become both productive and ⑤stressful.

Every day, we leave behind marks of the gases that warm our planet, much like footprints ①left in wet sand. These marks, often called our carbon footprint, come from small choices such as driving, eating, and using electricity. Many students think that only ②small factories create these marks, but ordinary habits at home also matter greatly. For example, turning off lights when leaving a room ③reduces the energy that power plants must produce. Walking or biking to school instead of riding in a car also ④lowers the amount of gas released into the air. In contrast, leaving devices plugged in all night quietly increases our footprint without our notice. Therefore, students who practice these simple habits regularly can ⑤shrink their footprint significantly.

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. Consumers are becoming more ①careless, checking whether reviews are sponsored before making a purchase. In the end, influencer marketing works best when it ②stays ③grounded in ④authenticity rather than mere ⑤popularity.

The subscription economy refers to a business model in which consumers pay a recurring fee to access goods or services rather than owning them outright. This model has expanded ①slowly beyond entertainment platforms into areas such as clothing, food, and even transportation. Companies benefit from predictable revenue, which allows them to plan production and marketing more ②efficiently than with one-time sales. For example, a monthly clothing subscription delivers new outfits ③automatically, saving customers the time and effort of shopping in stores. However, some critics argue that subscriptions encourage people to pay for services they ④barely use. Consequently, experts recommend reviewing subscription lists ⑤regularly to avoid unnecessary expenses.

Climate scientists frequently warn about tipping points, _______________. Unlike gradual warming, which unfolds steadily over decades, crossing a tipping point can produce dramatic consequences within a short period. For instance, as Arctic ice melts, it exposes darker ocean water that absorbs more sunlight than reflective ice, accelerating further melting in a self-reinforcing cycle. Similarly, scientists worry that a major ocean current, which currently redistributes heat across the planet, could slow dramatically if enough freshwater from melting glaciers dilutes the surrounding seawater. Once such thresholds are crossed, restoring the original balance may become nearly impossible, even if emissions are later reduced. Therefore, researchers argue that preventing these transitions matters more than merely slowing average temperature increases. Identifying how close each system stands to its threshold remains one of the most urgent challenges in climate research.

The Hillside Community Center is recruiting student volunteers for its summer programs. (A) No prior experience is necessary, since training will be provided on the first day. (B) Volunteers will help with tutoring younger children, organizing books, and assisting elderly residents. (C) Because the number of positions is limited, students should apply online before July 10th.

Imagine a classroom discussion where nearly everyone seems to support one viewpoint. (A) As more silence accumulates, the minority opinion appears rarer than it truly is, discouraging even more people from speaking. (B) A student who privately disagrees might quickly sense this imbalance and decide to remain quiet rather than face disapproval. (C) This exact pattern, described by the spiral of silence theory, also unfolds across entire societies and online communities.
