Which three parts of this excerpt from Edgar Allan Poe's "The Masque of the Red Death" highlight the suggestion that the powerful and wealthy in the story are insensitive toward the outbreak of the disease and those who are suffering?

"The 'Red Death' had long devastated the country. No pestilence had ever been so fatal, or so hideous."

"But the Prince Prospero was happy and dauntless and sagacious. When his dominions were half depopulated, he summoned to his presence a thousand hale and light-hearted friends from among the knights and dames of his court, and with these retired to the deep seclusion of one of his castellated abbeys."

"The external world could take care of itself. In the meantime it was folly to grieve, or to think. The prince had provided all the appliances of pleasure. There were buffoons, there were improvisatori, there were ballet-dancers, there were musicians, there was Beauty, there was wine. All these and security were within. Without was the 'Red Death.'"
