Assertion : In the past, famines were a major and recurring source of increased mortality.
Reason : Famines were caused by high levels of continuing poverty and malnutrition in an agro climatic environment that was very vulnerable to variations in rainfall.

Both A and R are true but R is not the correct explanation of A

The correct answer is Option 2: Both A and R are true but R is not the correct explanation of A

Assertion : In the past, famines were a major and recurring source of increased mortality. This is correct. Historically, famines were a primary driver of high mortality rates. Before modern transportation and global trade, a local crop failure often meant mass starvation because food could not be moved quickly from surplus areas to deficit areas.
Reason : Famines were caused by high levels of continuing poverty and malnutrition in an agro climatic environment that was very vulnerable to variations in rainfall. This is also true. Persistent poverty meant large sections of the population lived at subsistence level with little savings or food reserves. Malnutrition weakened people’s resistance to disease and starvation. At the same time, agriculture was heavily dependent on monsoon rainfall, making the agro-climatic environment highly vulnerable to rainfall fluctuations. When rainfall failed, food production collapsed and the poor were the worst affected.

Does R explains A? No

The Assertion talks about famines being a major and recurring source of increased mortality — that is, why deaths rose during famines. The Reason, however, primarily explains why famines occurred (due to poverty, malnutrition, and rainfall vulnerability). It focuses on the causes of famine, not directly on why mortality increased during famines (such as starvation, disease, weak relief systems, etc.).

Although poverty and malnutrition do make populations more vulnerable to death during famines, the Reason as worded mainly addresses the origin of famines, not the mechanism of increased mortality. Therefore, it does not directly explain the Assertion.

The correct reason would be: Famines caused increased mortality because extreme food scarcity led to widespread starvation and lowered immunity, making impoverished populations highly susceptible to opportunistic diseases and epidemics, while the lack of rapid transport prevented life-saving food distribution from other regions
