Task: Question Generation
Input (English):  The story concerns a love triangle. The protagonist, Dick Forrest, is a rancher with a poetic streak (his "acorn song" recalls London's play, "The Acorn Planters."). His wife, Paula, is a vivacious, athletic, and sexually self-aware woman (in one scene, she rides a stallion into a "swimming tank," emerging in "a white silken slip of a bathing suit that molded to her form like a marble-carven veiling of drapery.") Paula, like Charmian, is subject to insomnia; and Paula, like Charmian, is unable to bear children. Based on a reading of Charmian's diary, Stasz identifies the third vertex of the triangle, Evan Graham, with two real-life men named Laurie Smith and Allan Dunn. Even minor characters can be identified; Forrest's servant Oh My resembles London's valet Nakata. The long-bearded hobo philosopher Aaron Hancock resembles the real-lifelong-bearded hobo philosopher Frank Strawn-Hamilton, who was a long-term guest at the London ranch. Sculptor Haakan Frolich makes an appearance as "the sculptor Froelig"  and painter Xavier Martinez appears as the character "Xavier Martinez!"
The novel ends with Paula wounding herself mortally with a rifle the reader is not told explicitly whether it is suicide, as her lover Graham believes, or an accident, as she tells her husband and convincing a doctor to inject her with an overdose of morphine. As she drifts off, she says goodbye to both of her lovers:  Two bonnie, bonnie men. Good-by, bonnie men. Good-by, Red Cloud.... Stretch the skin tight, first. You know I don t like to be hurt."
Output (English): What is Froelig's profession?
