Task: Question Answering
Input (English): Charlize Theron plays Jill Young who as a child has witnessed the death of her mother and the mother of Joe, a baby ape, at the hands of poachers led by Andrei Strasser, (Rade erbedija). The poacher loses his thumb and trigger finger to the baby gorilla. Twelve years later, Jill has raised Joe (because of his size, the other gorillas won't accept him) and both are living in relative peace until a wildlife refuge director, Gregg O'Hara (Bill Paxton), convinces Jill that they would be safer from poachers if they relocated to the United States.The pair go to Hollywood, California (as in the original film) and win the hearts of the refuge staff. There, Jill is approached by Strasser, who has seen a news report about Joe and wants revenge because of the damage done to his hand 12 years ago. Jill fails to recognize Strasser as the poacher who killed both her mother and Joe's. Strasser tries to persuade Jill that Joe would be better off in his wildlife refuge back in Africa. Later, during a gala, Strasser's henchman uses a poacher's noisemaker to scare Joe into a frenzy. Joe trashes the gala, recognizes Strasser and tries to attack him. Joe is tranquilized and placed in a concrete bunker. When Jill learns that Joe may be euthanized she decides to take Strasser's offer. She and the refuge staff smuggle Joe out in a truck but on the way to the airport, Jill notices Strasser's missing fingers. He makes a remark that makes her realize he is the poacher who killed her mother. She crashes the truck and Joe escapes. Meanwhile Greg has also realized the identity of the poacher and goes after Jill and Joe. He finds Jill and they locate Joe at a carnival. Strasser arrives and in attempting to shoot Jill starts a fire which causes the Ferris wheel to break down. Joe catches Strasser and tosses him onto some electrical wires. In a poignant scene at the Santa Monica Pier, while saving a child Joe falls from the collapsing Ferris wheel. The scene is reminiscent of King Kong falling from the Empire State Building. Joe survives the fall and is shipped back to Africa to run free on his own refuge funded by donations from his fans., Question: Who killed Jill and Joe's mother?
