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. After that he found that all the flowers died, so he thought  that all types of music kill flowers. But his mother Susan told him that the reason the plants died was because he forgot to water them.
