- Step 1: Understand the question. The question asks for what cities must adopt to address urbanization challenges, requiring a specific solution mentioned in the passage.
- Step 2: Locate relevant information. The passage states, "To address these issues, cities must adopt sustainable practices, including green energy and efficient public transportation, to balance development with environmental health." This directly identifies "sustainable practices" as the solution.
- Step 3: Evaluate the options.
- Option (1): "Economic policies" is mentioned in the context of growth but not as a solution to challenges like overcrowding or pollution, so it is incorrect.
- Option (2): "Sustainable practices" directly matches the passage's wording, supported by examples like green energy and public transportation, making it the correct choice.
- Option (3): "Population control" is not mentioned in the passage as a solution, so it is irrelevant.
- Option (4): "Industrial expansion" is not referenced and could exacerbate issues like pollution, making it incorrect.
- Step 4: Verify specificity. The passage explicitly uses "sustainable practices" and provides examples, ensuring option (2) is a precise match. Other options introduce ideas not supported by the passage.
- Step 5: Cross-check for alternatives. The passage does not suggest other solutions like population control or industrial expansion, confirming that sustainable practices is the only correct answer.
- Step 6: Final conclusion. Option (2) Sustainable practices is the correct answer, as it directly reflects the passage's stated solution to urbanization challenges.
