Step-by-step explanation:
The student's question does not have a direct query but seems to be centered around a literary description, possibly from a novel or short story, wherein Dr. Underberg creates a unique type of candy. The text references sweetness and sight, indicating a fusion of sensory experiences which includes a visual appeal and taste pleasure, juxtaposed with the notion of nutrition which adds complexity to the nature of the candy.
