Which theme are you likely to encounter only in a text responding to Hurricane Katrina and not in a text responding to 9/11?

Hurricane Katrina was a natural disaster that caused flooding and other environmental problems, so a response to it may address environmental issues. The September 11 attacks were not a natural disaster, making that theme less likely in a text responding to 9/11. The other themes—crisis communication, disaster aftermath, and uncertainty about how to respond—could apply to both events.
