The September 11th attack continues to affect even those who have no memory of that day. It has affected the way we check into the airport and our safety protocols.

Answer: Heavy rainfall from the hurricane overwhelmed aging levees and flooded areas that were below sea level and populated mainly by families with low incomes.
Explanation: The third option also counts but it was more about the destruction it caused than "where" it caused destruction.

Basically, Hurricane Katrina sucked cause it killed people but to me, its pretty awesome. Natural disasters are pretty cool.
