Q. 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 change impacts. Our cities contribute to 65 percent 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 people.

Q 1. Which among the following is the most logical and rational inference that can be made from the passage given above?
(a) Our cities need to have well-defined administrative set-up with sufficient autonomy.
(b) Ever increasing population densities is a hindrance in our efforts to achieve sustainable development.
(c) To maintain and develop our cities we need to adopt sustainability related interventions.
(d) Public-Private Partnership mode of development is the viable long-term solution for the infrastructure and sustainability problems of India.
