Step-by-Step Solution
The complete worked solution.
Every step explained — no skipped algebra.
Q introduces the example, P adds further detail, R and S complete the structure and function descriptions. The logic behind this sequence often relies on connectors (like 'but', 'so', 'because'), temporal cues (like 'then', 'after that'), or thematic build-up (general to specific or cause to effect).
