Answer:
The two excerpts from the story which reflect the fact that Edgar Allan Poe personifies the Red Death are the following ones:
Excerpt 2.
Excerpt 3.
Step-by-step explanation:
In excerpt 2, the Red Death is described in terms of physical appearance and clothes:
"The figure was tall and gaunt..."
"The mask which concealed the visage was made so nearly to resemble the countenance of a stiffened corpse..."
In excerpt 3, the author refers to the Red Death as a male figure, which makes personification even more evident:
"His vesture was dabbled in blood—and his broad brow..."
"He had come like a thief in the night."
Poe personifies the Red Death in those two excerpts, since the Red Death, something abstract, is given human form and features. It is exactly what personification, a figure of speech, is all about.
