Problem: 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?
Solution: Oliver.
Explanation: In the sentence "He believes they make wallets and handkerchiefs", the pronoun "he" refers to name "Oliver".

Problem: Passage: Thieves Ed Dexter and Harry Ames are trying to steal some valuable pearls. When Ed discovers another gang, led by "Doc" Evans, has the same idea, he tips off the police to get rid of the competition. Then Ed and Harry get what they were after. When the authorities connect Vivian to the robbery (she had worked with Ed and Harry in the past, but not on this theft), government agent Ross McBride is assigned to get Vivian to lead him to her partners by pretending to be a crook named Danny Ackerman. However, Vivian quickly realizes Ross is a plant. Nonetheless, she plays along, as the other bunch of crooks is following her. Meanwhile, Ed has hidden the pearls in the handle of Vivian's hand mirror without her knowledge.
On their travels, Ross and Vivian stop at a farmhouse, where they help the distraught Dabsons with the birth of twins. Ross and Vivian gradually fall in love with each other. When he overhears her phoning Ed to tell him she is quitting her life of crime, he is at a loss what to do, "whipsawed" as he calls it. He confesses to her that he is government agent; she reveals that she already knows. He then embraces her, but drops the mirror he was holding, revealing the pearls. He does not believe her protestations of innocence. 
Question: What are the first names of the people that assist with the birth of twins?
Solution:
Ross.
