Final answer:
The quote 'Ralph was a shock of hair and Piggy a bag of fat' is a metaphorical description from 'Lord of the Flies' by William Golding and characterizes Ralph and Piggy in terms of their symbolic roles in the novel.
Step-by-step explanation:
The statement "Ralph was a shock of hair and Piggy a bag of fat" is not a true or false question but rather a description from William Golding's novel Lord of the Flies. These descriptions are used metaphorically to characterize two of the main characters, Ralph and Piggy. In the novel, Ralph's character is often associated with his fair hair which represents a sort of youthful leadership, while Piggy's character, with his physical appearance and glasses, represents the intellect and rationality in contrast to the others' descent into savagery.
