A rate itself changes, e.g., 20% to 25%, and the question distinguishes absolute vs relative change.
Percentage-point change is subtraction; percentage change is relative to the original rate.
Say the unit aloud: ‘points’ means subtract the rates directly.
Ask whether the question wants percentage points or relative percentage change.
