Problem: Given the question: Question: Who is Tango's younger sister? If there is no answer, please output "Insufficient information to provide an answer.". Movie title: Tango & Cash Context: Beverly Hills LAPD Lieutenant Raymond Tango (Sylvester Stallone) and Downtown Los Angeles Lieutenant Gabriel Cash (Kurt Russell) have earned themselves reputations for disrupting crime lord Yves Perret's (Jack Palance) smuggling operation in their respective jurisdictions. One day, they are informed of a drug deal taking place later that night. Both detectives meet for the first time at the location, but discover a dead body that is wire-tapped before the FBI arrive and surround the duo. Agent Wyler (Lewis Arquette) finds Cash's backup Walther PPK pistol on the floor with a silencer attached and arrests both Cash and Tango. At their murder trial, Tango and Cash are incriminated by an audio tape, secretly given to Wyler by Perret's henchman Requin and verified in court by an audio expert, which appears to reveal them shooting the undercover FBI agent after discussing a drug purchase. They plead no contest to a lesser charge in exchange for reduced sentences in a minimum-security prison, but are instead transported to a maximum-security prison to be housed with many of the criminals they arrested in the past. Once in prison, Tango and Cash are rousted from their bunks and tortured by Requin and a gang of prisoners until Matt Sokowski, the assistant warden and Cash's former commanding officer, rescues them. Sokowski recommends that they escape and provides them with a plan, but Tango refuses to go along with it. When Cash tries to escape, he finds Sokowski murdered and is attacked by prisoners. Tango rescues him and the duo escape. Once outside the prison walls, they proceed to go their separate ways when Tango tells Cash that should he need to contact him, he is to go to the Cleopatra Club and look for "Katherine." The detectives then visit the witnesses who framed them in court. Wyler admits to Tango that Requin was in charge of the setup, and Cash discovers that Skinner, the audio expert, made the incriminating tape himself. Cash finds Katherine, who helps him escape the night club as police move in on him on...

Problem: Given the question: Question: Who approaches the Union If there is no answer, please output "Insufficient information to provide an answer.". Movie title: Silkwood Context: Karen Silkwood (Meryl Streep), a worker at the Kerr-McGee Cimarron Fuel Fabrication Site (near Crescent, Oklahoma), shares a ramshackle house with two co-workers, her boyfriend Drew Stephens (Kurt Russell) and her lesbian friend Dolly Pelliker (Cher). She makes plutonium fuel rods for nuclear reactors, where she deals with the threat of exposure to radiation. She has become a union activist, concerned that corporate practices may adversely affect the health of workers. She is also engaged in a conflict with her former common-law husband in an effort to have more time with their three children. Because the plant has fallen behind on a major contract, employees are required to work long hours of overtime. She believes that managers are falsifying safety reports and cutting corners wherever possible, risking the welfare of the personnel. Karen approaches the union with her concerns and becomes active in lobbying for safeguards. She travels to Washington, D.C. to testify before the Atomic Energy Commission. She interacts with union officials who appear to be more interested in the publicity she is generating than her welfare and that of her co-workers. When Silkwood and other workers become contaminated by radiation, plant officials try to blame her for the incident. When she discovers that negatives of photographs of faulty fuel rods have been retouched and records of inadequate safety measures have been altered, she decides to conduct an investigation of her own. Complications arise in her personal life when Angela, a funeral parlor beautician, joins the household as Dolly's lover. Unable to deal with Silkwood's obsession with gathering evidence, her lover Drew moves out. Once she feels she has gathered sufficient documentation, Silkwood contacts a reporter from the New York Times and arranges a nighttime meeting.
