Task: Question Generation
Input (English): Passage: Frida begins just before the traumatic accident Frida Kahlo suffered at the age of 18 when the wooden-bodied bus she was riding in collided with a streetcar. She is impaled by a metal pole and the injuries she sustained plague her for the rest of her life. To help her through convalescence, her father brings her a canvas upon which to start painting. Throughout the film, a scene starts as a painting, then slowly dissolves into a live action scene with actors.
Frida also details the artist's dysfunctional relationship with the muralist Diego Rivera. When Rivera proposes to Kahlo, she tells him she expects from him loyalty if not fidelity. Diego's appraisal of her painting ability is one of the reasons that she continues to paint. Throughout the marriage, Rivera has affairs with a wide array of women, while the bisexual Kahlo takes on male and female lovers, including in one case having an affair with the same woman as Rivera.
The two travel to New York City so that he may paint the mural Man at the Crossroads at the Rockefeller Center. While in the United States, Kahlo suffers a miscarriage, and her mother dies in Mexico. Rivera refuses to compromise his communist vision of the work to the needs of the patron, Nelson Rockefeller; as a result, the mural is destroyed. The pair return to Mexico, with Rivera the more reluctant of the two.
Kahlo's sister Cristina moves in with the two at their San Ángel studio home to work as Rivera's assistant. Soon afterward, Kahlo discovers that Rivera is having an affair with her sister. She leaves him, and subsequently sinks into alcoholism. The couple reunite when he asks her to welcome and house Leon Trotsky, who has been granted political asylum in Mexico. She and Trotsky begin an affair, which forces the married Trotsky to leave the safety of his Coyoacán home.
Output (English): What is the full name of the person that the wife of the muralist have an affair with after moving back to Mexico?
