Historians use sequential (chronological) text structure to demonstrate events over a linear time span. They could use a cause and effect structure, as well as a comparison and contrast structure.
Explanation:
By using a chronological textual structure, historians allow the creation of a narrative where events create a linear passage of time. In this way, historians can create a text where events are organized to show the passage of time and the effects that this passage had on society from the beginning to the present.
Historians could use a cause and effect structure to show how attitudes and events in the past have resulted in events and situations in more recent times.
They can also use a structure of comparison and contrast, where they compare different times and evidence the factors where both are similar or different.
The House is an example of symbolism. By trying to hide the dead body of the old man from the policemen under the floorboard. The narrator is symbolically trying to hide the guilt and shame of his crime in his subconscious.
