Solution
Option 1 -> The passage explicitly calls her practices "quackery" and describes her as a "false prophetess," indicating she's not a legitimate doctor.
Option 2 -> The text directly uses the word "quackery" to describe her practices and states she was deceiving "simple people" and "cheating them of money they could ill afford."
Option 3 -> While she uses pigeons and creates a ritualistic setting, the passage's condemnatory tone and use of terms like "falsehoods" and "false prophetess" indicate she's a fraud, not a legitimate naturopath.
Option 4 -> There's no indication of energy healing or Reiki practices; the passage focuses on her deceptive behavior and false promises to incurable patients.
Hence, Option 2: A Quack -> The passage leaves no ambiguity about Mangala's nature, explicitly calling her practices "quackery" and describing her as a "false prophetess" who concocted "falsehoods" to deceive desperate syphilis patients, cheating them of money for a condition that had no known cure at the time -> correct
