Two distinct, fully labelled diagrams (price ceiling and tax) with correctly sloped curves, equilibrium points, and clear movements.

Comprehensive step-by-step explanations linking diagram shifts to article content and economic concepts, including elasticity effects and incentive changes.

Missing depiction of deadweight‐loss triangles to show welfare impacts.

Could include a long‐run supply curve to illustrate time‐lag effects visually.

Consistent and appropriate use of economic terminology (e.g., “price ceiling,” “indirect tax,” “PED,” “PES,” “government revenue”).

Clear definitions and integration of key terms within explanations, enhancing clarity.

Occasional awkward phrasing (e.g., “government trying to aid the significant increase”) that could be more precise.

Minor typos (“greenhouse sights”) and informal language that slightly reduce polish.
