Which of the following was not a reason why natural disasters unpredictably destroyed cities?

The question asks which choice was not a reason natural disasters destroyed cities. Cities located near hazards, governments without evacuation plans, and buildings made with weak materials could all make disasters more destructive. Military defenses and fire used as a weapon concern warfare, not natural disasters, so the best answer is “Cities lacked strong military defenses, and fire often was used as a weapon.”
