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

1. "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."

2. "The courtiers, having entered, brought furnaces and massy hammers and welded the bolts. They resolved to leave means neither of ingress nor egress to the sudden impulses of despair or of frenzy from within."

3. "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."
