Social media platforms rarely show users a neutral stream of information. Instead, recommendation algorithms ①are optimized to maximize engagement, and content that provokes strong emotion, particularly outrage, tends to hold attention longer than balanced reporting ever could. Over time, users ②exposed to a steady diet of emotionally charged content may come to believe that extreme opinions are far more common than they actually are, simply because those opinions ③dominate their feed. Researchers describe this as a distorted mirror: the platform reflects not society as it truly is, but a version ④shaping by whatever keeps people scrolling. Some platforms have experimented with reducing the visibility of outrage-driven content, only ⑤to see user engagement drop.

Time travel to the past has long fascinated physicists and philosophers alike, but it also generates a famously troubling ①contradiction. Suppose a traveler journeyed backward in time and, through some combination of accident and intention, prevented their own grandfather from ever meeting their grandmother. If the grandfather never had children, the traveler themselves would never have been born, which means the traveler could never have existed to make the trip in the first place. Yet if the traveler never made the trip, the grandfather would have ②survived to meet the grandmother after all, allowing the traveler to be born and eventually travel back in time. The story therefore ③loops endlessly, undermining itself at every turn rather than settling into any stable outcome. Some physicists resolve the paradox by arguing that any consistent timeline must ④permit such self-defeating actions to succeed freely, while others propose that a traveler who alters the past simply branches off into a separate, parallel timeline instead, an idea many find ⑤appealing precisely because it avoids the contradiction altogether.

As more schools shift toward digital textbooks and online assignments, a student without reliable internet access at home faces a disadvantage that has little to do with talent or effort. During recent years, this gap became ①impossible to ignore, as families in rural areas or low-income neighborhoods struggled to complete schoolwork that assumed a stable connection and a personal device. Some policymakers initially treated internet access as a ②convenience, comparable to cable television, rather than as infrastructure essential to modern life. That assumption is increasingly being reconsidered, particularly as more essential services move online by default. Closing this divide will require ③far less than simply distributing devices; it will demand ④sustained investment in the physical networks that carry information into every home, ⑤regardless of income or location.

Engineers are now exploring implants and prosthetics designed to give healthy people abilities beyond ordinary human limits. Supporters frame this as simply the next step in a long history of human enhancement, no different in principle from eyeglasses or vaccines. Critics counter that earlier enhancements were broadly available to anyone regardless of wealth, while cutting-edge neural and physical implants are likely to remain expensive for decades, potentially _______________.

Devices that translate brain activity directly into digital commands have moved from laboratory experiments to real medical use. As the technology improves, some developers envision a future in which these interfaces extend beyond restoring lost function toward enhancing healthy minds. This prospect raises a philosophical question: if a device can alter memory, mood, or decision-making, _______________. Neuroethicists argue that mental privacy may need to be recognized as a fundamental right before this technology becomes widespread.

City governments increasingly market dense networks of surveillance cameras as a safety upgrade. Yet the same infrastructure that catches criminals also creates a permanent record of where ordinary citizens go about their daily lives. Once a camera network exists, its purpose can quietly expand, often without new public debate. Civil liberties groups argue that _______________.

As private companies develop the technology to mine asteroids for rare metals and water, a legal question has become urgent: who 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 whether a private company may extract and sell what it finds there. Some governments have already passed domestic laws granting their own companies rights to material mined in space, a move that other nations view as _______________.

When consumers compare two products and assume that the one labeled "eco-friendly" is automatically the more sustainable choice, they often overlook the complexity involved in verifying such a claim. (A) Life cycle assessment, commonly abbreviated as LCA, is a systematic method developed to evaluate the environmental impact of a product across every stage of its existence. This method examines raw material extraction, manufacturing, transportation, use, and disposal, compiling data on energy consumption and emissions generated at each stage. (B) By tracing a product from its origin to its disposal, this approach reveals impacts that might otherwise remain hidden from consumers who see only the finished item on a shelf. For example, an electric vehicle may produce no emissions while being driven, yet the mining of metals for its battery can generate substantial environmental costs elsewhere. (C) Without accounting for these earlier stages, a superficial comparison could mistakenly present the vehicle as entirely emission-free. Therefore, researchers increasingly rely on life cycle assessment to make informed decisions rather than trusting labels alone.

Economists traditionally measured a community's wealth in terms of factories, income, or infrastructure, yet sociologists increasingly point to a less visible resource: social capital, the networks of trust and reciprocity that allow people to cooperate for mutual benefit. (C) However, social capital is not uniformly beneficial; tightly bonded networks can also exclude outsiders and reinforce existing inequality. (B) Communities rich in social capital tend to enjoy lower crime and more effective local government, because neighbors who trust one another can coordinate informally. (A) For this reason, researchers increasingly distinguish between bonding capital, which strengthens ties within a single group, and bridging capital, which connects otherwise separate communities.

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.
