Question

Considering the global disaster events between 1970--2020, arrange the years in decreasing order of number of total disaster events:

• A. C, D, A, B
• B. D, C, B, A
• C. C, D, B, A
• D. B, C, D, A

Hint:

For disaster event trend questions, remember that reported disaster events increased significantly from 1970 onward due to both real hazard increase and improved reporting.

Answer 1

The Correct Option is A

Concept: Disaster events have generally increased over time due to population growth, urbanisation, better reporting systems, climate-related hazards, and increasing exposure.

Step 1: Understand the time periods.
The given years represent different periods in the global disaster record. \[ B = 1980 \] \[ A = 1990 \] \[ C = 2000 \] \[ D = 2010 \]

Step 2: Understand decreasing order of disaster events.
The number of reported disaster events increased strongly up to around 2000. The year 2000 recorded more total disaster events than 2010, 1990, and 1980 in the given ordering.

Step 3: Arrange from highest to lowest.
The correct decreasing order is: \[ 2000 \rightarrow 2010 \rightarrow 1990 \rightarrow 1980 \] Using letters: \[ C, D, A, B \] Therefore, the correct answer is C, D, A, B.
