The law of diminishing returns.

Use b - law of diminishing returns to connect the rule to the data and decision in the question.

This matters because b - law of diminishing returns determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply b - law of diminishing returns to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: b - law of diminishing returns is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
