"A simplistic and modern pictogram representing the concept of a 'central issue' or 'central problem'. The image should feature a bold, black exclamation mark in the center on a white background, symbolizing urgency and importance. Instead of surrounding symbols, the focus should be entirely on the exclamation mark, with a minimalistic approach to emphasize the concept of a central issue. The design should be clear, easily recognizable, and suitable for use as an icon or symbol in various contexts, with a white background to ensure versatility in different design settings."
