Answer:
"The Haunting of Hill House" is a novel by Shirley Jackson, in which Dr. Montague is a scientist and researcher who seeks to study the paranormal activity in Hill House. He is portrayed as a rational thinker, who approaches the investigation of the supernatural with scientific curiosity and skepticism. On the other hand, Mrs. Montague is portrayed as being superstitious and having a tendency to jump to conclusions, lacking the rationality and scientific mindset of her husband.
Two examples of Eleanor being absorbed by Hill House are when she experiences strange and intense emotions and begins to see ghostly apparitions. For example, she feels a strong connection to the house, and finds that she is unable to leave it, even though she wants to. In addition, she begins to experience vivid and haunting dreams, which only serve to further entrench her in the grip of Hill House.
The allusion to the House of Hades in "The Haunting of Hill House" reveals that Hill House is a place of darkness, death, and suffering, just as the ancient Greek underworld was considered to be a place of darkness and suffering. This allusion serves to further underscore the sinister and oppressive nature of Hill House, and suggests that the characters are trapped in a place from which they may never escape.
