As private companies develop the technology to mine asteroids for rare metals and water, a legal question once confined to science fiction has suddenly ①become urgent: who, if anyone, owns the resources of outer space? Existing international treaties state that no nation may claim sovereignty over celestial bodies, but they say remarkably little about ②whether a private company may extract and sell what it finds there. Some governments have already passed domestic laws ③granting their own companies rights to material mined in space, a move that other nations view as a unilateral attempt to settle a question that should ④decide collectively. Supporters of space mining argue that new resources could ease shortages on Earth and fund further exploration, while critics warn that treating space as an open frontier for extraction risks ⑤repeating the same environmental and political mistakes that colonization caused on Earth.

To compensate for their carbon emissions, many individuals and companies now ①purchases carbon offsets, financial credits that fund projects such as planting trees or building renewable energy plants. The idea is appealing: paying for an equivalent amount of carbon to be absorbed elsewhere should cancel out the harm caused by activities like flying. However, critics argue that this system often ②functions as a convenient excuse for postponing genuine emission cuts rather than achieving them. For example, a newly planted forest may take decades to absorb the promised carbon, and it could later ③burn down or be cut, erasing any benefit. Moreover, some offset projects would have happened anyway, meaning the credits fund nothing truly ④additional. Therefore, relying heavily on offsets allows businesses ⑤to maintain harmful practices while appearing responsible.

Psychologists have long studied a mechanism called the variable reward schedule, in which rewards ①arrive unpredictably rather than after every single action. Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. When someone posts a photo, they cannot predict exactly when likes will appear, nor ②how many they will eventually receive. This uncertainty triggers a small burst of dopamine each time the phone ③is checked, regardless of whether the result is disappointing or thrilling. Consequently, users often refresh their feeds compulsively, ④hoping the next check will finally bring a satisfying reward. What makes this troubling is that technology companies deliberately designed notification systems using insights borrowed from gambling research, rather than ⑤stumble upon them by accident.

Among strategies for improving concentration, the Pomodoro Technique remains one of the most widely recommended methods for students and workers. This technique involves ___________. After completing four of these cycles, a longer break of fifteen to thirty minutes is usually taken to allow mental recovery. The method assumes that sustained focus becomes harder to maintain as time passes, so frequent short breaks prevent mental fatigue from building up. Students preparing for exams report finishing reading assignments faster when they follow this structured rhythm instead of studying without interruption. Office workers find that dividing large projects into short, timed intervals makes overwhelming tasks feel more manageable. Because each interval has a clear start and end, procrastination becomes less tempting, since beginning a single twenty-five-minute session requires less commitment than beginning an entire project.

The Greenfield Public Library will offer a variety of special programs for students during summer vacation. From July 20th to August 14th, students can join reading clubs, writing workshops, and science experiment classes. ___________. Interested students should sign up at the front desk or through the library's website before space runs out.

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 ___________.

Companies have discovered that ordinary advertisements no longer capture the attention of young consumers as effectively as they once did. (A) As a result, many brands now spend a large portion of their advertising budgets on influencer partnerships rather than television commercials. (B) This is because influencers build long-term relationships with their audiences, which makes recommendations feel personal rather than commercial. (C) However, brands must choose their partners carefully, since an influencer's reputation can directly affect how a product is perceived.

This new emphasis on space, however, has not pleased everyone who cares deeply about libraries. For most of the twentieth century, a library was simply a quiet room full of books, and visitors were expected to stay silent while they searched the shelves. ( ① ) Today, many public libraries look completely different. ( ② ) Alongside the usual shelves, you might find group study rooms, comfortable sofas for reading, computer labs, and even small recording studios for podcasts. ( ③ ) Librarians say this change did not happen by accident. As more information moved online, fewer people needed a library simply to find facts, so librarians began asking what their communities actually needed instead. ( ④ ) The answer, in many neighborhoods, turned out to be space itself: a warm, free place where students could study together, job seekers could print a resume, and children could attend a story hour. ( ⑤ ) Some critics worry that libraries are drifting away from their original mission of preserving books. Librarians respond that reading and gathering have always belonged together, and that a library survives only by changing with its readers.

주어진 문장: This is precisely why scientists treat these thresholds with such urgency, rather than viewing them as distant, abstract possibilities. Climate scientists frequently warn about tipping points, thresholds beyond which a small additional change triggers a large, often irreversible shift in the climate system. ( ① ) Unlike gradual warming, which unfolds steadily over decades, crossing a tipping point can produce dramatic consequences within a short period. ( ② ) 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. ( ③ ) 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. ( ④ ) Once such thresholds are crossed, restoring the original balance may become nearly impossible, even if emissions are later reduced. ( ⑤ ) 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.

주어진 문장: Yet this same tendency also carries a hidden drawback. Sociologists use the term homophily to describe the tendency of people to form connections with others who share similar backgrounds, opinions, or interests. ( ① ) This principle explains why classmates from the same major often become close friends, while coworkers with shared hobbies naturally gravitate toward one another. ( ② ) Because similarity reduces the effort required to understand another person's perspective, relationships built on shared traits tend to feel comfortable and require less negotiation. ( ③ ) However, this same comfort can narrow the range of viewpoints someone encounters, since surrounding oneself with similar people limits exposure to different ideas. ( ④ ) Social media platforms intensify this pattern through recommendation algorithms that suggest new friends based on shared interests or similar browsing history. ( ⑤ ) As a result, users often find their online circles becoming increasingly homogeneous, filled with people who think and behave much like themselves.
