Final answer:
A 'C&C' signpost in literature occurs when the author presents unexpected information that creates a contrast or contradiction, influencing the plot or characters and not necessarily tied to the story's climax, rising action, or falling action.
Step-by-step explanation:
In literature, a "C&C" signpost, referring to 'Contrasts and Contradictions', can occur when the author presents unexpected information, challenge or change a character's thinking, or take the plot in a new direction. This does not happen exclusively at the beginning of a story, during a climactic moment, or only in non-fictional texts, but rather at any point where such a contrast or contradiction is relevant to the storytelling or character development.
The term 'climax' in literature is defined as the peak of the action, the main showdown, or the central event of the story where the conflict comes to a head. It represents a turning point, after which the story moves towards resolution. The climax is essential as it is usually the moment of greatest tension and drama within the narrative, where characters might face decisive confrontations, have important epiphanies, or overcome significant internal struggles.
