The objective is to arrange the sentences into a logical paragraph. Initially, evaluate each sentence:
- Sentence 1 posits that human brains are incapable of processing all environmental alterations.
- Sentence 2 introduces the term 'change blindness,' which defines the phenomenon described in Sentence 1.
- Sentence 3 reinforces the concept from Sentence 1 by stating that our brains cannot be privy to all occurrences surrounding us.
- Sentence 4 offers an illustration of this phenomenon, detailing how individuals may fail to notice significant changes happening in their immediate view.
In sequence, Sentence 1 serves as the opening statement, establishing the overarching concept. Sentence 3 follows by elaborating on the brain's limitations previously mentioned in Sentence 1. Subsequently, Sentence 4 provides a practical example, validating the concept introduced. Lastly, Sentence 2 concludes the paragraph by defining 'change blindness,' the phenomenon that has been the focus of the preceding sentences. Therefore, the established order is 1342.
