Direction for the following 2 (two) items: Read the following two passages and answer the items (71-72) that follow. Your answers to these items should be based on the passages only.

Our cities are extremely vulnerable to climate change because of large concentrations of populations and poor infrastructure. Moreover, population densities are increasing in them but we have not yet developed the systems to address climate changes impacts. Our cities contribute to 65 per cent of the GDP, but there are not enough facilities to cater to the needs of the people. It is important to address the issues of air quality, transport, etc., that are vital to identifying sustainable solutions. We need to involve citizens in city planning and create an ecosystem that meets the needs of the people.

Which among the following is the most logical and rational inference that can be made from the passage given above?

The correct option is: "To maintain and develop our cities we need to adopt sustainability related interventions."

Step-by-Step Explanation & Logical Reasoning:

1. Analysis of the Passage:
- The passage highlights the vulnerability of our cities to climate change due to high population density and weak infrastructure.
- It notes that while cities generate 65% of the GDP, the existing facilities are insufficient to meet people's needs.
- The author explicitly states: "It is important to address the issues of air quality, transport, etc., that are vital to identifying sustainable solutions. We need to involve citizens in city planning and create an ecosystem that meets the needs of the people."

2. Evaluating the Options:
- Option 1 ("Our cities need to have well-defined administrative set-up with sufficient autonomy."): The passage does not discuss administrative set-ups or autonomy. Hence, this cannot be inferred directly from the text.
- Option 2 ("Ever increasing populations densities is a hindrance in our efforts to achieve sustainable development."): While population density is mentioned as a vulnerability factor, the passage does not conclude that high population density itself is an insurmountable hindrance, but rather that we lack proper systems and sustainable solutions.
- Option 3 ("To maintain and develop our cities we need to adopt sustainability related interventions."): This directly aligns with the main point of the passage, which emphasizes identifying sustainable solutions (e.g., addressing air quality, transport, and citizen involvement in planning) to protect and develop our economically vital cities.
- Option 4 ("Public-Private Partnership mode of development is the viable long-term solution..."): The passage makes no mention of Public-Private Partnerships (PPP).

Conclusion:
The most logical and rational inference supported strictly by the passage is that sustainability-related interventions are essential for the maintenance and development of our cities.
