Task: Question Generation
Input (English): Passage: On Fifth Avenue, an orphaned kitten named Oliver is left abandoned after his fellow orphaned kittens are adopted by passersby. Wandering the streets by himself in search of someone to adopt him, Oliver meets a laid-back mongrel named Dodger who assists the kitten in stealing food from a hot dog vendor named Louie. Dodger then flees the scene without sharing his bounty with Oliver. Oliver follows Dodger all throughout the streets until he eventually arrives at the barge of his owner, a pickpocket named Fagin, along with his meal, to give to his friends: Tito the chihuahua, Einstein the Great Dane, Rita the Saluki, and Francis the bulldog. Oliver sneaks inside, located below the docks, and is discovered by the dogs. After a moment of confusion, he is then received with a warm welcome. Fagin comes in and explains that he is running out of time to repay the money he borrowed from Sykes, a nefarious shipyard agent and loan shark. Sykes tells Fagin that the money must be paid in three days, under the threat of resolving to violence. Sykes's dobermans, Roscoe and DeSoto, attack Oliver, but the cat is defended by Fagin's dogs. Immediately thereafter, a depressed Fagin returns to the barge, lamenting that he only has three days to find the money he owes Sykes. After the dogs cheer him up, Fagin is introduced to Oliver, and, considering that they all need help, accepts him into the gang.
Output (English): Who are the dog in Fagin's gang?
