2. Plot: The plot refers to the sequence of events in a story. The events and conflicts that occur throughout the plot can contribute to the development of the theme. For example, if a story revolves around the theme of perseverance, the plot might involve a character facing numerous challenges and overcoming them through determination and resilience.
