Direction for question : In the following question, a short passage is given with one of the lines in the passage missing and represented by a blank. Select the best of the five answer choices given to make the passage complete and coherent.
Rapid urbanisation has enabled cities to become engines of economic growth and helped reduce urban poverty levels. But the same process has made them highly vulnerable to the severe effects of climate change. Although cities use only two percent of the land mass, they are responsible for 75 percent of the human induced greenhouse gas (GHG) emissions released into the atmosphere, making them the biggest contributors to global warming. This could put cities in a big environmental risk, which would make them susceptible to climate- change-induced disasters such as sea level increase and frequent flooding. Urban sprawl, combined with unsustainable transportation planning and energy guzzling building practices, has been the main source for the GHG emission. Given the accelerated expansion of urban populations, increasing waste volumes could become a big concern in the conceivable future.______________ It is vital that urban and climate change policies synergise at the local body level and a sustainable growth pattern is adopted on priority. Simultaneously the resilience of cities, particularly of their poor areas, has to be vastly improved so that they can better manage, the impact of climate change.
