Few ideas in policy debate ①provoke as much philosophical unease as the notion that a government might deliberately steer citizens toward better choices while leaving every option technically available. Defenders insist that freedom is preserved as long as no option is banned and no penalty is attached, ②arguing that a citizen who is merely steered, rather than coerced, remains free to choose otherwise. Critics counter that this defense rests on an impoverished notion of liberty, one that ③ignores how engineered defaults and calculated framing can shape decisions just as powerfully as an outright prohibition would. If a policy is designed because officials expect it to bypass conscious deliberation, these critics ask, can the resulting choice still ④call autonomous, even though no law was broken? The dispute ultimately turns on what freedom actually ⑤requires: the mere absence of coercion, or a decision-making process that remains transparent and undistorted.

The discovery of CRISPR gene-editing technology gave scientists a tool ①precise enough to correct a single mistaken letter in the human genome, raising hope for curing inherited diseases that have resisted treatment for generations. Yet the same precision that makes CRISPR so promising also makes it ②dangerous in the wrong hands. Editing a gene in a sperm, egg, or early embryo does not simply change one patient; it alters the genetic code passed down to every future generation, a decision no single person should be allowed to make ③alone. Scientific organizations around the world have therefore drawn a careful line, ⑤permitting gene editing to treat disease in existing patients while ④permitting any edit that would be inherited by their descendants. Critics worry, however, that as the technology becomes cheaper and more widely available, this line will become harder to enforce than it is to draw.

Psychologists studying human judgment often describe the mind as operating through two distinct systems rather than a single unified process. System 1 works quickly and automatically, generating impressions without any noticeable sense of effort. System 2, by contrast, is slow, deliberate, and demanding, engaged only when a problem requires careful calculation or conscious reasoning. Most daily decisions are handled almost entirely by System 1, which allows people to function efficiently without exhausting their limited mental resources. This efficiency comes at a cost, however, because _______________. As a result, a judgment often feels most confident precisely at the moment when it has skipped the careful scrutiny that could have caught its own mistake.

Bacteria have been cutting up invading viral DNA for billions of years, long before any scientist thought to borrow the trick for use in a laboratory. The CRISPR-Cas9 system relies on a short guide RNA that matches a specific DNA sequence, _______________. Once Cas9 arrives at the target site, it slices both strands of the DNA helix, and the cell's own repair machinery rushes in to mend the cut, often introducing a small change in the process. By supplying the cell with a template during this repair step, scientists can direct that machinery to insert a specific new sequence rather than merely disabling the original gene. What once required years of painstaking work to alter a single gene can now be accomplished within days.

The ancient puzzle known as the ship of Theseus asks a deceptively simple question. If every plank of a wooden ship is replaced one by one over many years, is the vessel that eventually results still the same ship it once was? Most people's first instinct is to answer yes, since each individual replacement seems too small to erase the ship's identity. The puzzle grows far sharper, however, once a second twist is introduced. Suppose a careful collector gathered every discarded plank and reassembled them into a second vessel, built exactly as the original once stood. Two ships would then exist side by side, each with an equal claim to being the genuine one, and no obvious way to decide between them. Philosophers return to this old story again and again, not because they care about timber, but because it forces us to ask whether identity depends on continuous material, continuous form, or _______________.

For decades, most vaccines worked by injecting a weakened or inactivated version of a pathogen, coaxing the immune system into recognizing an enemy it had never truly fought. (A) mRNA vaccines take a fundamentally different route, delivering only a short genetic instruction wrapped in a protective lipid capsule, one that tells the body's own cells how to manufacture a single harmless piece of a virus's outer surface protein. (B) Once those cells display the fragment, the immune system learns to recognize it as foreign and builds a defense, without ever having encountered the actual pathogen. (C) Because the vaccine contains no live virus and cannot alter a cell's own DNA, developers can redesign the genetic instructions within weeks whenever a pathogen mutates, a speed that has convinced many researchers the same platform could eventually fight diseases far beyond infectious illness.

Long before humans learned to drill for oil, microorganisms had already mastered the art of converting sunlight and carbon dioxide into stored chemical energy. (A) Modern biofuel research borrows this ability, cultivating algae or engineered bacteria in large tanks where they can be coaxed into producing oils and sugars that can be refined into fuel usable in existing engines. (B) Unlike crops grown for corn-based ethanol, which compete directly with food production for arable land, many algae strains can thrive in shallow ponds, wastewater, or even coastal seawater unsuitable for conventional agriculture. (C) Engineers have also learned to boost oil yield through genetic tinkering, yet producing biofuel at a cost competitive with fossil fuel remains difficult, since harvesting and processing the organisms consumes a substantial share of the energy the fuel itself will eventually provide.

When a country physician named Edward Jenner noticed that milkmaids who had caught cowpox seemed immune to smallpox, he set in motion a medical revolution without fully understanding why it worked. (A) This method produced genuine successes, eventually eliminating smallpox worldwide and reducing diseases such as polio and measles, but each new vaccine still required years of laboratory work with no guarantee of success. (B) Advances in molecular biology eventually allowed researchers to isolate a single protein from a pathogen's surface, producing vaccines with fewer side effects, and the most recent shift toward delivering genetic instructions represents the latest chapter in this story. (C) For nearly two centuries afterward, vaccine development proceeded largely by trial and error, weakening or killing a pathogen and testing whether the resulting preparation could train the immune system without causing disease itself.

People also want to actually do certain things and to actually be a certain kind of person, not merely to feel as though they had. Philosopher Robert Nozick asked his readers to imagine a machine capable of producing any experience they desired, from writing a great novel to falling in love, all indistinguishable from reality once they were plugged in. ( ① ) Neuroscientists would simply stimulate the brain to generate a lifetime of perfectly satisfying experiences, and the person floating in the tank would have no memory of ever choosing to enter it. ( ② ) If pleasure and the avoidance of pain were truly all that mattered, as classical hedonism claims, then everyone should rush to connect themselves permanently to such a machine. ( ③ ) Yet when people actually consider the offer, most hesitate, and many refuse outright. ( ④ ) Nozick took this reluctance as evidence that human beings care about more than the quality of their internal sensations. ( ⑤ ) Maintaining genuine contact with a reality beyond one's own mind, it turns out, matters just as much as how that mind happens to feel.

주어진 문장: A well-designed multimedia lesson, for instance, presents narration and matching diagrams simultaneously rather than forcing students to consult them separately. Cognitive load theory begins from the premise that working memory, the mental workspace in which incoming information is temporarily held and manipulated, can accommodate only a limited number of novel elements at any given moment, in stark contrast to the comparatively vast capacity of long-term memory. ( ① ) When instructional materials introduce more interacting elements than this narrow workspace can simultaneously process, learners experience what theorists call cognitive overload, a condition under which comprehension deteriorates and errors multiply regardless of how motivated the learner might be. ( ② ) Because much of this burden arises not from the intrinsic difficulty of the subject matter itself but from the manner in which information is presented, instructional designers can substantially reduce unnecessary strain by eliminating redundant explanations, aligning visual and verbal elements so that learners need not mentally integrate scattered sources, and gradually withdrawing guidance as competence develops. ( ③ ) Ignoring these principles, by contrast, ( ④ ) risks overwhelming novices with demands that exceed their processing capacity, however well-organized the underlying content may be. ( ⑤ )
