Example Input: Passage: Frusciante continued to collaborate with his friend Omar Rodríguez-López. Along with providing guitar work to The Mars Volta's studio albums, The Bedlam In Goliath and Octahedron, and Rodríguez-López's solo albums Se Dice Bisonte, No Búfalo and Calibration (Is Pushing Luck and Key Too Far), he functioned as executive producer for Rodríguez-López's directorial film debut, The Sentimental Engine Slayer.

The first is the album Omar Rodriguez-Lopez & John Frusciante, an album with just the two of them, the other a quartet record, Sepulcros de Miel, consisting of Rodríguez-López, Frusciante, Juan Alderete and Marcel Rodríguez-López.
Frusciante also contributed music to the documentary film, Little Joe, based upon Joe Dallesandro. In 2009, Frusciante appeared in the documentary, "The Heart is a Drum Machine." His full-length, forty-five-minute interview is available in the special features of the DVD release.On December 7, 2011, the Red Hot Chili Peppers were named 2012 inductees for the Rock And Roll Hall Of Fame. In an interview that same day, Anthony Kiedis talked about Frusciante and if he would attend the ceremony. Kiedis stated, "It would be a guess on my behalf on whether or not he'll come. I can't imagine that he would, but it's a 'you never know' kind of thing. I haven't talked to him in quite a while. I don't know where he's at these days. He'll obviously be more than welcome, and embraced if he does. If he doesn't, that's cool too." Flea also spoke about Frusciante by saying "He left us so many great gifts. He's a phenomenal musician and songwriter who gave so much to our band. All the feelings I have for him not being in the band any more ... He really took us to a higher level." Frusciante eventually declined to be present for the Red Hot Chili Peppers' induction into the Rock and Roll Hall of Fame in April.

Example Input: 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. 
Question: Who is the sister of the wife of the man that paints a mural at Rockefeller Center?
Example Output:
Cristina.
