Step-by-step explanation:
The statement that correctly compares the floods in 1927 and 2005 is:
"Each one created a refugee crisis and affected politics locally and nationally."
Both the 1927 Great Mississippi Flood and Hurricane Katrina in 2005 created significant refugee crises, with people displaced from their homes seeking shelter and assistance. These events also had significant political implications at local and national levels due to the response and management of the disasters. The other statements are not accurate comparisons for various reasons.
