Sentence 4 establishes the premise that human consciousness is typically viewed as an emergent property of the brain, providing foundational context. Sentences 1 and 3 are considered. Sentence 1 states that no individual neuron stores complex information like self-awareness or emotions. Sentence 3 elaborates, postulating that the collective neuronal activity within the nervous system produces complex human emotions. Therefore, Sentence 3 logically follows Sentence 1 and supports the concept of emergent properties from component interactions. Sentence 2 concludes the paragraph by acknowledging that although the exact mechanism of emergence in the brain is not fully understood, neurobiologists agree that intricate interconnections between brain components result in emergent qualities. This sentence concludes the discourse and reinforces the idea presented in Sentence 4.
The logical sequence is (A): 4132
The four sentences (labelled 1, 2, 3 and 4) given 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.
1. Veena Sahajwalla, a materials scientist at the University of New South Wales, believes there is a new way of solving this problem.
2. Her vision is for automated drones and robots to pick out components, put them into a small furnace and smelt them at specific temperatures to extract the metals one by one before they are sent off to manufacturers for reuse.
3. E-waste contains huge quantities of valuable metals, ceramics and plastics that could be salvaged and recycled, although currently not enough of it is.
4. She plans to build micro factories that can tease apart the tangle of materials in mobile phones, computers and other e-waste.
