The benefit of posting pictures of flooding after a major storm is?
a. building community resilience through prevention, mitigation and preparedness
b. building situation awareness throughout the community
c. communicating directly and responding to false or conflicting information
d. saving lives in a fast moving disaster event

The answers are actually quite similar, and the question is not easy!

We can immediately reject option D: as posting pictures does not directly save lives.
 We can also reject answer C as posting pictures does not have to be connected to false information.

Option B can be rejected because it's not aboput situation awareness if it's after the event.

So the correct answer is A!

Urban growth invariably feeds increased commercialization and industrialization. it requires continually expanding land areas. when urbanization rates are high, and countries do not have the institutional and managerial capacities or economic wherewithal to manage such rapid growths, they exert intense pressure on the types and nature of the resulting settlements. they contribute to the development of overcrowded slums and shanty towns without adequate essential services and necessary infrastructure.-by asit k. biswas and cecilia tortajada
