Question

One reason Hurricane Katrina was so devastating for New Orleans is that
many people had to be rescued by helicopter.
no emergency shelters were available.
people were surprised by the storm.
many residents had not evacuated.

Answer 1

many residents had not evacuated.

Many people lacked transportation, money, or places to go (and some were reluctant to leave), so they stayed in the city when the levees failed and flooding occurred, greatly increasing the disaster’s human toll.
