Concept: Disasters cause direct and indirect losses. Direct economic losses include damage to buildings, infrastructure, crops, houses, roads, bridges, and other physical assets.
Step 1: Checking Assertion (A).
The assertion says that disasters cause direct economic loss. This is correct because disasters damage property, infrastructure, and productive assets.
\[
\text{Assertion (A)} = \text{Correct}
\]
Step 2: Checking Reason (R).
The reason says that direct economic loss attributed to disasters increased from 2005 to 2019. This is also correct as disaster-related economic losses have increased over time due to higher exposure, urbanisation, and asset concentration.
\[
\text{Reason (R)} = \text{Correct}
\]
Step 3: Checking whether Reason explains Assertion.
Reason (R) tells about an increase in disaster losses over a time period. But it does not explain why disasters cause direct economic loss. It only gives a trend.
Therefore, both statements are correct, but Reason is not the correct explanation of Assertion.
