Task: Question Answering
Input (English): Passage: In ancient times, the Amazons, a proud and fierce race of warrior women, led by their Queen, Hippolyta, battled Ares, the god of war, and his army. During the battle, Hippolyta specifically targeted and beheaded her son Thrax, whom Ares forcibly conceived with her and who is fighting for his father. Hippolyta then defeated Ares, but Zeus stopped her from delivering the death strike. Instead, Hera bound his powers with magic bracers so that he was deprived of his ability to draw power from the psychic aura of violence and death he could instigate, and only another god could release him. In compensation, the Amazons were granted the island of Themyscira, where they would remain eternally youthful and isolated from Man in the course of their duty of holding Ares prisoner for all eternity. Later, Hippolyta was granted a daughter, Princess Diana, whom she shaped from the sand of the Themyscirian seashore and gave life with her own blood.
Over a millennium later, an American fighter pilot, USAF Colonel Steve Trevor, is shot down in a dogfight and crash-lands his YF-23 on the island, where he soon runs afoul of the Amazon population, including the combative Artemis. Steve and Diana meet and fight, and Diana defeats him, taking him to the Amazons. After interrogating him with the use of the Amazons' golden lasso, Hippolyta decides he is not an enemy of the Amazons and as such, tradition dictates that an emissary be tasked to ensure his safe return to his own country. Diana volunteers, but is assigned to guard Ares's cell instead since her mother argues that she has not enough experience in dealing with the dangers of the outside world. Diana defies her mother and, her face hidden by a helmet and her guard duty covered by her bookish but kind-hearted Amazon sister Alexa, participates in contests of strength and wins the right to take Trevor back to his home. 
Question: What is the name of the person who could only be released by another god?
Output (English): Ares.
