Based on the context and the answer, generate a question. 

Context: You ever wonder how something got its name ? Me too . As I was preparing to walk from the car to the store , I found a long - neglected umbrella under the seat and used it , as Tropical Storm Fay would ' ve soaked me through in the 15 second walk . And I start wondering why it 's called an umbrella , and then as the word is repeated in my head , it eventually sounds nonsensical , like any word you repeat over and over again .

Answer:

The tropical storm was causing a lot of rain .



Why did they decide to use an umbrella ?
