1.3.2.2a - concept of 'demand'

The concept of 'demand'.

Use a - concept of 'demand' to connect the rule to the data and decision in the question.

This matters because a - concept of 'demand' determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply a - concept of 'demand' to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: a - concept of 'demand' is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
