I want to know the answer to the following question:
Why did San Diego schools close during the Cedar Fire?
All the background I'm provided with is that "In addition to damage caused by the fire, smoke resulted in a significant increase in emergency room visits due to asthma, respiratory problems, eye irritation, and smoke inhalation; the poor air quality caused San Diego County schools to close for a week.". Is that enough to answer the question?
Answer: yes
