Input: Consider Input: Question: How much does the person Iron Man showed up at Grand Central Station with weigh? Passage:Doom hires various villains to find the bricks for him, starting with Abomination and Sandman, who hold Grand Central Station at ransom for a Cosmic Brick. Iron Man and Hulk show up at the station, with Spider-Man joining them later on, and together they manage to defeat the two villains, who are subsequently imprisoned in a nearby maximum security prison called the Raft, while Nick Fury leaves the Cosmic Brick in Mister Fantastic's care at the Baxter Building. Mister Fantastic and Captain America arrive at the building shortly after to examine the Cosmic Brick, but find it under attack by Doctor Octopus, who steals the brick and leaves his Octobots behind to keep the heroes busy. After destroying them, Mister Fantastic and Captain America chase after a fleeing Doctor Octopus across several rooftops, with their battle going through the Daily Bugle as well, where Peter Parker, Spider-Man's alter-ego, sees them and suits up as Spider-Man to lend a hand. The three heroes eventually battle Doctor Octopus in Times Square and manage to defeat him, but he tosses the brick to Green Goblin, who takes it to Oscorp. Fury sends Black Widow and Hawkeye to get it back, with Spider-Man joining them later on. They eventually confront Green Goblin in his office, but he opens a trapdoor that sends the heroes to Oscorp's underground lab, where they are forced to fight Venom and his symbiote-infected scientists. Although the heroes defeat Venom, the Goblin escapes with the brick via helicopter.

Input: Consider Input: Question: On what continent was Kilekwa born? Passage:Kilekwa was born in Zambia, in a Bissa village, in the Mbisa tribe, near Lake Bangweulu. He was born "Chilekwa"; Ki-, he says in his autobiography, "is a Swahili prefix". He was enslaved in the 1870s as a boy in what he called "the Maviti wars" (the term may point to "any brigand rather than to a specific ethnic group"). His mother was unable to pay his ransom eight yards of calico clothand he was taken to the coast, headed for the Persian Gulf. However, the ship of his enslavers was stopped by the Royal Navy; HMS Osprey took them to Muscat. The group spent a month or so there, but then Kilekwa and another boy, Mambwala, were volunteered to serve on the Osprey and become seamen. They did odd jobs while the Osprey, looking for slave dhows, sailed throughout the Gulf and up the Euphrates to Basra (in present-day Iraq). One day, while most of the sailors were on shore in Bushehr, Persia, slavers tried to kidnap them but were prevented. They traveled as far as India and went sightseeing in Bombay. When the Osprey was to return to England, the two were transferred to HMS Bacchante; they were in Bombay again for the Golden Jubilee of Queen Victoria in 1887.
