Parrots are so adept at mimicking other voices because it helps them survive in the wild. Parrots are social animals that live together in large flocks. These flocks use complex vocal communication to signal danger, to locate each other, and to reinforce social bonds. The more complex a parrot’s vocal repertoire, the better its ability to interact within the flock, leading to a higher chance of survival and reproduction.Which choice best describes the function of the third sentence in the overall structure of the text?It explains how parrots learned to mimic other voices.eliminatedIt points to a problem scientists have with understanding parrot evolution.eliminateIt describes the range of a parrot’s vocal repertoire.eliminateIt explains how parrot flocks use vocal communication.

ExplanationQuestion 14:The four sentences (labelled 1, 2, 3, 4) below, when properly sequenced would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer:Complex computational elements of the CNS are organized according to a “nested” hierarchic criterion; the organization is not permanent and can change dynamically from moment to moment as they carry out a computational task.Echolocation in bats exemplifies adaptation produced by natural selection; a function not produced by natural selection for its current use is exaptation --feathers might have originally arisen in the context of selection for insulation.From a structural standpoint, consistent with exaptation, the living organism is organized as a complex of “Russian Matryoshka Dolls” -- smaller structures are contained within larger ones in multiple layers.The exaptation concept, and the Russian-doll organization concept of living beings deduced from studies on evolution of the various apparatuses in mammals, can be applied for the most complex human organ: the central nervous system (CNS).Show Answer
