Answer: the percentage of fatalities that occurred due to flooding
Step-by-step explanation:
The most dangerous thing to a human being is the thing that might threaten their existence which means that if you were to speak on why something is dangerous, you should include how it can affect the existence of a human being such as through death or injury.
This tropical storm report should be no different. If you want to make sure that people understand that inland flooding is dangerous, mention the percentage of fatalities (people who die) from inland flooding to show that it threatens human existence.
