Task: Question Generation
Input (English): Passage: One night in Portsmouth, England in 1787, a press gang breaks into a local tavern and presses all of the men drinking there into naval service.  One of the men inquires as to what ship they will sail on, and the press gang leader informs him that it is HMS Bounty. Upon inquiring as to who the captain is, another of the men is told the captain is William Bligh and attempts to escape, as Bligh is a brutal tyrant who routinely administers harsh punishment to officers and crew alike who lack discipline, cause any infraction on board the ship, or in any manner defy his authority. The Bounty leaves England several days later on a two-year voyage over the Pacific Ocean. Fletcher Christian, the ship's lieutenant, is a formidable yet compassionate man who disapproves of Bligh's treatment of the crew. Roger Byam is an idealistic midshipman who is divided between his loyalty to Bligh, owing to his family's naval tradition, and his friendship with Christian.
During the voyage, the enmity between Christian and Bligh grows after Christian openly challenges Bligh's unjust practices aboard the ship. When the ship arrives at the island of Tahiti, where the crew acquires breadfruit plants to take to the West Indies, as intended, Bligh punishes Christian by refusing to let him leave the ship during their stay. Byam, meanwhile, sets up residency on the island, living with the island chief, Hitihiti, and his daughter, Tehani, and compiling an English dictionary of the Tahitian language. Hitihiti persuades Bligh to allow Christian a day pass on the island. Bligh agrees but quickly repeals the pass out of spite. Christian disregards the order and spends his one-day off the ship romancing a Tahitian girl, Maimiti. Christian promises her he will be back someday.
Output (English): What's the full name of the lieutenant's friend aboard the Bounty?
