Given the task definition, example input & output, solve the new input case.
Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.
Example: Context: Architecturally, the school has a Catholic character. Atop the Main Building's gold dome is a golden statue of the Virgin Mary. Immediately in front of the Main Building and facing it, is a copper statue of Christ with arms upraised with the legend 'Venite Ad Me Omnes'. Next to the Main Building is the Basilica of the Sacred Heart. Immediately behind the basilica is the Grotto, a Marian place of prayer and reflection. It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858. At the end of the main drive (and in a direct line that connects through 3 statues and the Gold Dome), is a simple, modern stone statue of Mary.
Question: To whom did the Virgin Mary allegedly appear in 1858 in Lourdes France?
Output: Saint Bernadette Soubirous
This is the correct answer. Because the question is asking for the name of the person and following sentence from the passage answers it: It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858.

New input case for you: Context: Paul Stanton (Mulroney) and his wife Diane (Diane Kruger) are a couple whose daughter is dying from a rare degenerative lung condition. The only thing that can save her life is a lung transplant from an organ donor. The movie starts when the donated lung fails to arrive correctly. The movie goes back and forth between the present and the events leading up to it. In the present day, Paul goes to Juarez, Mexico to find a man called Dr. Navarro. After leaving his cell number at many local hospitals, somebody finally contacts Paul. In the past, Dr. Rubin (Arquette), who's treating their daughter (Stallard), had given them information regarding Paul's associate, Harrison (Shepard), who somehow managed to get an organ transplant for himself, possibly from the black market. Paul confronted Harrison and finally managed to get Dr. Navarro's name from him. Harrison told him that he was contacted by Navarro and he didn't know how to reach him. Back in the present day, Paul is ambushed by a couple of Navarro's guys that tell him to stay away. After an arduous search, Paul finally finds out that Dr. Navarro is actually Dr. Martinez (Perez) from a local hospital that he visited previously for his wounds. Paul confronts Martinez and asks him to find a lung donor for his daughter, who only has one week to live. Martinez agrees to help him for a $250,000 cash payment. The next day, Martinez tells Paul that he has found a matching donor for his daughter. Paul tells Diane to go to Juarez and prepare their daughter for the transplant operation. Little does Paul know that the donor is actually a live person; Martinez and his men have planned a hit-and-run accident to get the lung implant from a local street boy. Paul discovers this fact and tells Diane about it. Diane tells him that she does not want to know where the donor comes from. Paul confronts Martinez at the operating table. Martinez tells Paul to make a choice: to go ahead with the operation or disband the operation knowing that they won't be able to find another match in time to save his daughter's life. The next scene shows Paul and Diane at their daughter's funeral. Diane gives Paul an accusing look blaming him for their daughter's death. Meanwhile, elsewhere, the local boy that was supposed to be the organ donor is alive and playing soccer with his friends.
Question: What illegal operation is Dr. Navarro involved?
Output:
lung transplant
