Task: Question Generation
Input (English):  In a Prologue, the characters in the drama are introduced by an  Animal Tamer  as if they are creatures in a travelling circus. Lulu herself is described as  the true animal, the wild, beautiful animal  and the  primal form of woman .
When the action of the play starts, Lulu has been rescued by the rich newspaper publisher Dr Sch n from a life on the streets with her alleged father, the petty criminal Schigolch. Dr Sch n has taken Lulu under his wing, educated her and made her his lover. Wishing however to make a more socially advantageous match for himself, he has married her off to the medic Dr Goll.
In the first Act Dr Goll has brought Lulu to have her portrait painted by Schwarz. Left alone with him, Lulu seduces the painter. When Dr Goll returns to confront them, he collapses with a fatal heart attack.
In Act Two, Lulu has married the painter Schwarz, who, with Sch n s assistance, has now achieved fame and wealth. She remains Sch n s mistress, however. Wishing to be rid of her ahead of his forthcoming marriage to a society belle, Charlotte von Zarnikow, Sch n informs Schwarz about her dissolute past. Schwarz is shocked to the core and  guillotines  himself with his razor.
In Act Three Lulu appears as a dancer in a revue, her new career promoted by Sch n s son Alwa, who is now also infatuated with her. Dr Sch n is forced to admit that he is in her thrall. Lulu forces him to break off his engagement to Charlotte.
In Act Four Lulu is now married to Dr Sch n but is unfaithful to him with several other men (Schigolch, Alwa, the circus artist Rodrigo Quast and the lesbian Countess Geschwitz). On discovering this, Sch n presses a revolver into her hand, urging her to kill herself. Instead, she uses it to shoot Sch n, all the while declaring him the only man she has ever loved. She is imprisoned for her crime.
Her escape from prison with the aid of Countess Geschwitz and subsequent career down to her death at the hands of Jack the Ripper in London are the subject of the sequel, Pandora s Box. It is now customary in theatre performances to run the two plays together, in abridged form, under the title Lulu.
Output (English): Why does Dr Goll Collapse?
