Option 2 states that 'ancient cities were not organized this way,' but the passage specifically mentions that "several of the world’s earliest cities were organized along egalitarian lines." Therefore, option 2 is not accurate as it makes a broad and inaccurate generalization about all ancient cities. Option 3 and 4 involve inferences based on the passage rather than directly addressing the main idea.Option 1, which refers to evidence provided in the passage and aligns with the focus on specific examples of ancient cities, seems to be the best choice. It emphasizes the information presented in the paragraph rather than making broad assumptions.
