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.

Imagine rewriting a bacterium's code the way a programmer ①edits a line of software, and much of what synthetic biology promises begins to make sense. Researchers in this field assemble standardized genetic parts into circuits ②that can be inserted into a cell, instructing it to perform a task that no natural organism would carry out. Because these circuits are built from interchangeable parts rather than designed from scratch each time, a circuit tested in one lab can often ③reusing, with minor adjustments, in an entirely different application. Critics note that biological systems rarely behave as predictably as electronic circuits, since a gene ④inserted into a new cell can interact with existing pathways in unexpected ways, occasionally producing results no engineer intended. Even so, as the catalog of standardized parts keeps expanding, engineers are gaining confidence ⑤to design increasingly complex systems, treating the cell as a chassis onto which new functions can be loaded.

Suppose a mysterious being with a near-perfect track record of ①predicting human choices presents a player with two boxes. Box A always contains a visible thousand dollars, while Box B contains either a million dollars or nothing at all, depending on a prediction the being made before the game even began. If the being predicted the player would take only Box B, it ②placed a million dollars inside; if it predicted the player would take both boxes, it left Box B empty. The player may choose to take only Box B, or to take both boxes, and the prediction has already ③been made and cannot change. One line of reasoning says taking both boxes is strictly better, since whatever is already inside the boxes cannot ④be altered by the player's choice at this point. A second line of reasoning says taking only Box B is better, since the being's near-perfect accuracy means that choosing both boxes almost ⑤guaranteeing an empty Box B.

Many large companies now rely on artificial intelligence ①to screen job applications before a human ever sees them. These systems promise efficiency, scanning thousands of resumes in seconds and ranking candidates according to patterns ②drawn from previous hiring decisions. However, this reliance on historical data creates a troubling risk. If a company's past hiring favored a particular group, the algorithm may learn to treat that pattern as a marker of success and quietly reproduce it, even when no one ③intending discrimination. Unlike a human interviewer, the system offers no explanation for its choices, which makes the bias difficult ④to detect until an outside audit reveals it. Some researchers argue that fairness cannot be added afterward; it must ⑤be built into the system's design from the very beginning.

Devices that translate brain activity directly into digital commands have moved from laboratory experiments to real medical use, allowing paralyzed patients to control a robotic arm or type a message using thought alone. As the technology ①improves, some developers envision a future in which brain-computer interfaces extend beyond restoring lost function toward enhancing healthy minds. This prospect raises a philosophical question that medicine alone cannot answer: if a device can alter memory, mood, or decision-making, at what point does the assistance stop being a tool and start ②reshaping the very identity of the person using it. Neuroethicists argue that mental privacy, the ability to keep one's own thoughts ③exposed to external access or manipulation, may need to be recognized as a fundamental right before this technology becomes ④widespread. This concern is likely to grow ⑤more urgent as the devices become more powerful.

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.

Working memory refers to the mental workspace in which information is temporarily held and manipulated while a person performs a cognitive task. Such tasks include solving an arithmetic problem, following a rapid conversation, or holding a phone number in mind before dialing it. In the mid-twentieth century, the psychologist George Miller proposed that this workspace could accommodate roughly seven discrete items. His claim proved so influential that it became widely known as the magic number seven. Subsequent research, however, revealed that Miller's estimate was somewhat generous, since it failed to account for the complexity of the material being remembered. Nelson Cowan later argued that when rehearsal strategies are prevented and attention is tightly controlled, _______________. This discrepancy suggests that what earlier studies had measured was not raw storage capacity itself but a hybrid quantity inflated by clever strategies. Contemporary psychologists therefore distinguish between the fixed limit of working memory and the flexible techniques that allow individuals to transcend that limit.

Long before calculus existed, the Greek philosopher Zeno constructed a series of paradoxes designed to show that motion itself might be logically impossible. In one version, a swift runner named Achilles races a slow-moving tortoise that is given a modest head start. Common sense insists that Achilles will quickly overtake the tortoise, yet Zeno's argument suggests otherwise. By the time Achilles reaches the tortoise's starting point, the tortoise has crawled a little further ahead; by the time Achilles closes that new gap, the tortoise has advanced again, however slightly. This process repeats endlessly, generating _______________. Zeno concluded that Achilles could never actually catch the tortoise, a conclusion that plainly contradicts everyday experience.

A single fertilized egg eventually gives rise to every cell type in the human body, from neurons to bone, a feat that has fascinated biologists for more than a century. (A) Because harvesting these cells traditionally required destroying a human embryo, the research provoked ethical objections fierce enough to slow funding and legislation in several countries for years. (B) A breakthrough arrived when scientists discovered that ordinary adult skin cells could be reprogrammed into a state resembling embryonic versatility without ever touching an embryo, opening a path for stem cell research that far more scientists and funding agencies are now willing to support. (C) Embryonic stem cells retain much of that original versatility, capable in principle of developing into almost any tissue, which is why researchers have long viewed them as a promising raw material for repairing damaged organs.

The reason, he insisted, lies outside the speaker's mind entirely, in the actual chemical composition of the substance being referred to. Imagine a distant planet identical to Earth in every visible respect, except that the clear liquid its inhabitants call "water" is not H2O but a different compound, XYZ, that happens to look, taste, and behave exactly the same. ( ① ) When an Earthling and a Twin Earthling each say the word "water," they seem to mean the same thing, since neither could tell the substances apart without a chemistry lab. ( ② ) Philosopher Hilary Putnam used this scenario to argue that the meaning of a word is not determined solely by what happens inside a speaker's head. ( ③ ) Even though the two speakers hold identical thoughts and mental images when they use the word, their statements refer to two different substances. ( ④ ) Meaning, Putnam concluded, depends partly on the world outside the mind, not merely on the private mental states of whoever happens to be speaking. ( ⑤ )
