Final answer:
Antagonist, a character who protests war kills another character at the end of a novel
Subplot, a side story that does not interfere with the main one
Exposition, one paragraph explaining a series of bank robberies
Suspense, if this is present it encourages readers to turn the pages quickly
Foreshadowing, if a novel mentions how a character fears water and then drowns this technique is used
Step-by-step explanation:
The question pertains to literary terms and techniques.
A character who protests war but ends up killing another at the end of a novel exhibits the complexity of characterization and can also highlight the conflict of the story which is often central to the plot and is the antagonist.
A side story that runs parallel to the main one without interfering is known as a subplot, adding layers and richness to the narrative.
An exposition is often seen in the beginning section of a story but can also appear as a standalone paragraph within a novel to provide necessary background information, such as explaining a series of bank robberies.
If a story contains elements that encourage readers to turn the pages quickly, it's using suspense, which is a crucial technique to maintain readers' interest.
Lastly, a character's fear of water followed by drowning is an example of foreshadowing, which hints at future events and adds depth to the storytelling.
