Example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs. 
Question: Who believes Fagin's gang make wallets and handkerchiefs?
Output: Oliver.
In the sentence "He believes they make wallets and handkerchiefs", the pronoun "he" refers to name "Oliver".

Kate, who is dating Christian's older brother Elliot, confides that she suspects Elliot may be having an affair with Gia, who is also his business associate. When Ana returns home, she encounters Jack Hyde, who attempts to kidnap her. Ana's security team subdues him and he is arrested.
