Input: The story of the rise of politician Willie Stark from a rural county seat to the governor's mansion is depicted in the film. He goes into politics, railing against the corruptly run county government, but loses his race for county treasurer, in the face of unfair obstacles placed by the local machine. Stark teaches himself law, and as a lawyer, continues to fight the local establishment, championing the local people and gaining popularity. He eventually rises to become a candidate for governor, narrowly losing his first race, then winning on his second attempt. Along the way he loses his innocence and becomes as corrupt as the politicians he once fought against. When his son becomes paralyzed following a drunk driving accident that kills a female passenger, Stark's world starts to unravel and he discovers that not everyone can be bought off. The story has a complex series of relationships. All is seen through the eyes of the journalist, Jack Burden, who admires Stark and even when disillusioned still sticks by him. Stark's campaign assistant, Sadie is clearly in love with Stark and wants him to leave his wife, Lucy. Meanwhile, Stark philanders and gets involved with many women, taking Jack's own girlfriend, Anne Stanton, as his mistress. When Stark's reputation is brought into disrepute by Judge Stanton (Anne's uncle), he seeks to blacken the judge's name. When Jack finds evidence of the judge's possible wrongdoing, a quarter century earlier, he hides it from Stark. Anne gives the evidence to Stark, who uses it against her uncle, who immediately commits suicide. Anne seems to forgive Stark, but her brother, the surgeon who helped save Stark's son's life after the car crash, cannot. The doctor eventually assassinates Stark after Stark wins an impeachment investigation. The doctor in turn is shot down by Sugar Boy, Stark's fawning assistant. The main plot is a thinly disguised version of the rise of real-life 1930s Louisiana Governor, Huey Long, Long's efforts to blacken the name of Judge Benjamin Pavy, and Long's assassination by the Judge's son-in-law (compared to nephew, as in the film), Dr. Carl Weiss.

Input: In 1933, Freya Roth is a young German girl engaged to a Nazi party member. When she realizes the true nature of his political views she breaks the engagement and turns her attention to anti-Nazi Martin Breitner. Her father, Professor Roth, does not abide by the attitude of the new order towards scientific fact. Though his stepsons Erich and Otto eagerly embrace the regime, Professor Roth's reluctance to conform leads at first to a boycott of his classes and eventually to his arrest and a sentence of forced physical labor. His wife is permitted a five-minute visit in which the professor urges her to take Freya and her younger brother and leave the country. He dies soon after. Freya is kept from leaving by Nazi officials suspicious of her father's work. She reunites with Martin and together they attempt to escape through a mountain pass. A squad reluctantly led by her former fiancee gives chase and Freya is fatally wounded, dying in Martin's arms just after they cross the border. Later, Erich and Otto are informed of their sister's death. Erich responds with anger towards Martin.  Otto, however, experiences an epiphany, and flees their once-happy home, rejecting the Nazis and their cruel doctrine. 
Question: Who is Erich and Otto's stepfather?
Output: 


Output: Professor Roth
