Which item is NOT typically an indicator of a nuclear attack?

• A. Mushroom cloud.
• B. Electromagnetic pulse.
• C. Warning or threat of an attack.
• D. A routine weather pattern.

Answer: (D)

Understanding indicators of a nuclear attack means recognizing signs that a nuclear event is occurring or imminent. A mushroom cloud is a clear visual marker of a nuclear detonation. An electromagnetic pulse is a secondary effect of a nuclear explosion that can disrupt power and communications, so unusual, widespread electrical disturbances can point to such an event. A warning or threat of an attack reflects intent and could indicate an imminent strike, especially in coordinated incidents. A routine weather pattern, however, is ordinary atmospheric behavior with no link to nuclear activity, so it does not serve as an indicator of a nuclear attack.
