Handling Competing and Nested Claims

"Read the following excerpt from a policy journal: 'For two decades, energy economists framed the transition to renewable power as a technology problem: build better panels, larger turbines, cheaper batteries, and the market would handle the rest. That framing produced remarkable results. Solar generation costs fell by roughly ninety percent between 2010 and 2020, and onshore wind became the cheapest source of new electricity in most of the world. Yet global emissions continued to rise through the same period, and power systems in several advanced economies still struggled to absorb clean energy at scale. A growing camp of researchers now argues that the bottleneck has shifted. The constraint, they contend, is no longer generation technology but the unglamorous systems around it: transmission lines that take a decade to permit, grid operators running on software from another era, and market rules written for fleets of fossil plants. Countries that treat the transition as an engineering project, this camp warns, will keep winning cost curves while losing the atmosphere. The next phase of decarbonization, in this view, is a governance project—rewiring institutions, permits, and markets as thoroughly as the grid itself.' Which sentence best states the article's thesis?"

"Read the following excerpt from a management review: 'When offices emptied in 2020, executives predicted that remote work would dissolve organizational culture within months. Five years later, the obituaries look premature. Firms that invested deliberately in remote culture—documenting decisions in shared spaces, rotating meeting times across time zones, funding periodic in-person gatherings—report retention rates comparable to their pre-pandemic benchmarks. Firms that simply relocated work to video calls report the opposite: siloed teams, weakened mentoring, and managers who evaluate visibility rather than output. The difference between the two groups is not policy generosity. It is design. Culture in distributed organizations behaves less like an atmosphere and more like a product: it must be specified, built, maintained, and revised, or it decays. This reframing carries a hard implication for leadership. Culture can no longer be delegated to osmosis—the slow absorption of norms that happens when people share a hallway. It requires the same intentional investment that companies already make in their technology stacks.' Which statement is a supporting point rather than the article's central thesis?"

"Read the following excerpt from a public health journal: 'Public health agencies occupy an uncomfortable position in democratic societies: they hold authority over behavior—what people may smoke, inject, or refuse—without the electoral mandate that legitimizes other regulators. Historically, agencies resolved this tension by leaning on scientific prestige, presenting their mandates as technical judgments rather than political choices. That strategy is failing. As vaccination, masking, and dietary guidance became flashpoints in partisan conflict, surveys recorded steep declines in public trust toward health agencies across the political spectrum. Some commentators read this collapse as a communication failure and prescribe better messaging. The evidence suggests a deeper problem. When agencies defended contested policies by pointing to their expertise alone, they asked citizens to accept authority on faith, at precisely the moment when faith in institutions was thinning. Rebuilding legitimacy, then, requires more than clearer explanations of scientific findings. It requires agencies to make their values visible—to show which trade-offs between liberty and safety they chose and why—and to accept that some citizens, fully informed, will still disagree. Trust, on this account, cannot be restored by authority. It must be earned through transparency, even at the cost of some decisions being rejected.' A reader proposes two candidate theses. Which one passes the full-text coverage test?"

"Complete the sentence: In a multi-paragraph article, the single sentence that states the author's overall main point—the claim that every section exists to support—is called the ____.
