What type of music do flowers like best?

'''What type of music do flowers like best? '''was Rodrick's science project when he was in middle school. At first Rodrick put the flowers in different places where different type of music were played. Within a week all the flowers died, and Rodrick thought the music killed them. But Susan told him that the reason the plants died was because he never watered them.
