German sociologist Ferdinand Tönnies distinguished between two fundamentally different forms of social organization, ①which he termed Gemeinschaft and Gesellschaft. Gemeinschaft, often ②translated as community, describes relationships bound by close kinship, shared tradition, and face-to-face familiarity, typical of small villages where individuals know one another across an entire lifetime and act according to unwritten customs. Gesellschaft, often translated as society, describes relationships organized around impersonal contracts, self-interest, and formal law, typical of large cities where interactions occur between relative strangers ③who cooperate for specific, limited purposes. Tönnies did not regard one form as simply superior to the other; rather, he saw the shift from Gemeinschaft toward Gesellschaft as a defining feature of modernization, one that brought greater efficiency and individual freedom while ④weaken the dense emotional bonds that once held communities together. Contemporary sociologists continue to debate whether digital networks represent a genuine revival of Gemeinschaft-style community or merely ⑤extend Gesellschaft's impersonal logic into new spaces.

Behavioral economists have long observed that people tend to feel the pain of losing something more intensely than the pleasure of gaining an equivalent amount, a tendency known as loss aversion. Consider an investor who refuses to sell a declining stock, clinging to the hope that its price will eventually recover, even when all available evidence indicates that selling and reinvesting elsewhere would be more rational. As a result, loss aversion frequently pushes individuals toward ___________ rather than toward the outcome that would maximize their overall welfare.

A plastic bag that fully decomposes within months rather than lingering for centuries sounds almost too convenient to be real, yet certain bioplastics on the market do exactly that under the right conditions. (A) Not every bioplastic biodegrades quickly, however, and some marketed as eco-friendly break down only in industrial composting facilities that reach conditions rarely found in a backyard compost heap or the open ocean. (B) Unlike conventional plastic, derived almost entirely from petroleum, many bioplastics are synthesized from renewable feedstocks such as corn starch or sugarcane, sometimes with the help of bacteria engineered to produce plastic-like polymers as a byproduct of their metabolism. (C) Critics point out that growing crops for bioplastic production can compete with food crops for farmland and water, which is why researchers are now exploring bioplastics made from agricultural waste and algae instead of dedicated crops.

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.

Social unrest does not always emerge from the poorest conditions; it frequently erupts when circumstances are improving but not quickly enough to satisfy rising expectations. (A) Political scientist Ted Gurr illustrated the pattern with what is often called the J-curve: revolutions tend to follow a period of sustained improvement that is then followed by a sudden reversal. (B) This paradox lies at the heart of relative deprivation theory, which holds that discontent arises less from objective hardship than from a perceived gap between what people expect and what they actually receive. (C) Because the theory centers on perception rather than raw statistics, it helps explain why relatively prosperous societies can experience intense protest while long-impoverished societies sometimes remain comparatively quiet.

주어진 문장: This asymmetry alone can be enough to prevent an otherwise reasonable deal from ever being reached. Picture a woman who receives a plain ceramic mug as a free gift at a conference and, later that afternoon, refuses to sell it for anything less than triple its price in the gift shop downstairs. ( ① ) Before she owned the mug, she would never have paid extra for it; once it became hers, however, its value in her mind rose sharply, simply because she now possessed it. ( ② ) Researchers have repeatedly observed this pattern across many everyday objects, from coffee mugs and concert tickets to office chairs and old furniture inherited from relatives. ( ③ ) Owners consistently demand more money to give something up than buyers are willing to offer for that very same item, revealing a curious asymmetry rooted purely in possession itself. ( ④ ) Some economists argue that this effect explains why negotiations over inherited property so often collapse, since each side quietly attaches a different value to what it currently holds. ( ⑤ ) Understanding this bias, therefore, helps explain why simply owning something, even briefly, can distort how fairly people judge its true worth.

Confined in this controlled setting, the organisms grow far faster than they ever would in the wild. Long before humans learned to drill for oil, microorganisms had already mastered the art of converting sunlight and carbon dioxide into stored chemical energy. ( ① ) Modern biofuel research borrows this ability, cultivating algae or engineered bacteria in large tanks. ( ② ) There, they can be coaxed into producing oils and sugars that can be refined into fuel usable in existing engines. ( ③ ) 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. ( ④ ) Engineers have also learned to tinker with the metabolic pathways of these organisms, boosting oil yield far beyond what any wild strain would naturally produce on its own. ( ⑤ ) Despite this progress, 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.

In purely material terms, of course, rejecting the offer leaves the responder objectively worse off than accepting it would have. In a typical round of the ultimatum game, a proposer offers to keep eighty percent of a sum of money, leaving only twenty percent for the responder. ( ① ) A responder who values only material gain should accept this offer without hesitation, since twenty percent of something is still more than one hundred percent of nothing. ( ② ) In practice, however, a substantial proportion of responders reject such lopsided offers outright. ( ③ ) Both participants then receive nothing, an outcome that a purely self-interested calculator would never choose voluntarily. ( ④ ) Researchers interpret this pattern as evidence that people are willing to incur a personal cost in order to punish behavior they perceive as exploitative. ( ⑤ ) This willingness to sacrifice material gain for the sake of fairness appears consistently across many different cultures, though the specific threshold for what counts as an unfair offer can vary considerably.

Critics note a further irony: when something goes wrong, such as a hacked exchange or a lost password, there is often no institution left to appeal to. Blockchain technology was originally promoted as a way to remove the need for trusted middlemen, allowing strangers to exchange value directly and verify transactions through a shared, tamper-resistant ledger. ( ① ) In theory, this design distributes power away from any single institution and toward the network as a whole. ( ② ) In practice, however, a small number of large players have come to dominate many blockchain networks. ( ③ ) They control enough computing power or currency to influence outcomes that were supposed to be decided collectively. ( ④ ) Whether decentralization can survive this concentration of power remains one of the technology's most unresolved questions. ( ⑤ )

This finding is particularly striking given that the two groups of employees faced no difference whatsoever in the financial terms of the plan itself. Employers have long experimented with how retirement savings plans are presented to new hires. ( ① ) In one common arrangement, employees receive a form and must actively check a box to begin contributing a portion of their salary to a savings account. ( ② ) Under this opt-in arrangement, a substantial share of eligible employees never get around to enrolling, often citing simple procrastination rather than genuine disinterest in saving. ( ③ ) When employers instead enroll employees automatically and require them to check a box only if they wish to withdraw, participation rates climb to well over ninety percent. ( ④ ) Only the framing of the choice, not its economic substance, appears to determine whether employees end up saving for retirement. ( ⑤ ) This gap between the two arrangements reveals just how powerfully a default setting can shape decisions that people generally regard as carefully considered.
