Step 1: Understanding the Concept:
The question asks to identify the characteristic that does NOT describe subsistence farming. Subsistence farming is a form of agriculture in which nearly all of the crops or livestock raised are used to maintain the farmer and the farmer's family, leaving little, if any, surplus for sale or trade.
Step 3: Detailed Explanation:
The passage describes subsistence farming as being "characterized by uncertain yields, low incomes and low capital formation."
\[\begin{array}{rl} \bullet & \text{(A) uncertainty in the crop yield: This is a key feature, as subsistence farmers often depend on natural conditions like monsoon rains. The passage confirms this.} \\ \bullet & \text{(B) poor capital gain to farmers: This is also a key feature. Farmers produce little surplus, leading to low incomes and "low capital formation" as the passage states.} \\ \bullet & \text{(C) dependence on natural resources: Subsistence farming typically relies heavily on natural rainfall, traditional seeds, and organic manure, with minimal external inputs.} \\ \bullet & \text{(D) reliance on modern farming tools and techniques: This is the opposite of subsistence farming. Subsistence farming is characterized by the use of traditional, simple tools and techniques. Reliance on modern tools like tractors, HYV seeds, and chemical fertilizers is characteristic of commercial or intensive farming.} \\ \end{array}\]
Step 4: Final Answer:
Subsistence farming is not characterised by reliance on modern farming tools and techniques.
