The peak/low trap is building Task 1 around the highest and lowest values while ignoring overall trends, stability, and line crossovers. A chart is not a trivia list. Examiners reward staged movement (rose steadily, plateaued, converged). Write overview trend language first; use peaks only if they support the main story.
