In ecоlоgicаl studies оf corаl reef systems, scientists hаve long observed that reef biodiversity is closely linked to the presence of grazing herbivores such as parrotfish and surgeonfish. These species maintain algal populations in check, thereby allowing coral larvae to successfully settle and grow. In systems where herbivorous fish are removed—whether through overfishing or habitat degradation—algal overgrowth can lead to phase shifts in which coral-dominated ecosystems are replaced by algal-dominated ones. This transition has been associated with significant losses in biodiversity and is notoriously difficult to reverse once established. Recent research has focused on whether targeted interventions, such as the reintroduction of herbivorous fish species or artificial reef construction, can restore coral dominance, but results remain inconsistent due to variations in local nutrient levels, water temperature, and human activity.Which choice best describes the function of the underlined sentence in the passage as a whole?
The fоllоwing text is аdаpted frоm Jаne Austen's 1811 novel Sense and Sensibility. Elinor Dashwood and her sister Marianne are discussing their differing views on emotional restraint.Elinor, this eldest daughter, whose advice was so effectual, possessed a strength of understanding, and coolness of judgment, which qualified her, though only nineteen, to be the counsellor of her mother. She had an excellent heart; her disposition was affectionate, and her feelings were strong—but she knew how to govern them: it was a knowledge which her mother had yet to learn.As used in the passage, what does the word "govern" most nearly mean?
Text 1Urbаn ecоlоgists hаve lоng wondered how both crows аnd ravens can thrive in the same cities while feeding on many of the same resources. According to conventional wisdom, one species should eventually displace the other after outcompeting it for food. Yet both birds continue to expand across large metropolitan regions. Field surveys and casual observations have produced many partial explanations, but none has fully solved the puzzle of coexistence. If crows and ravens truly overlap in diet and habitat, why does one not prevail? Researchers still lack a satisfactory account that explains how closely related scavengers persist side by side in crowded urban landscapes.Text 2Ornithologist Priya Raman and colleagues connect this coexistence to fine scale separation in time and space. Using GPS tags, camera traps, and stable isotope analyses, they found that crows concentrate around schoolyards and parks during daylight, while ravens favor early morning loading docks and taller rooftops. The birds also differ in flight height and perch choice, which limits direct encounters at food sources. Raman's team concludes that apparent overlap masks reduced interaction. In cities, microhabitat and daily schedule differences likely make head to head competition between crows and ravens much less common than previously assumed.Based on the texts, how would Raman and colleagues (Text 2) most likely respond to the "conventional wisdom" discussed in Text 1?
