The passage given below is followed by four alternative summaries. Choose the option that best captures the essence of the passage. The Common Raven is widely recognized not merely for its large size and distinct call but for its remarkable cognitive abilities, often placing it among the most intelligent of all avian and even mammalian species. Studies demonstrate that ravens exhibit sophisticated behaviors such as causal reasoning, future planning, and tool use, showing an understanding of object permanence that rivals primates. Crucially, they possess highly developed social intelligence, engaging in tactical deception to hide food caches from competitors and communicating complex information through a varied repertoire of calls. This combination of ecological and social problem-solving skills confirms the raven's status as a preeminent non-human intellect.
