In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.
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?
Example solution: Oliver.
Example explanation: In the sentence "He believes they make wallets and handkerchiefs", the pronoun "he" refers to name "Oliver".

Problem: Passage: Bacon's output is characterised by sequences of images. He told Sylvester that his imagination was stimulated by sequences and that "images breed other images in me". His series were not always planned or painted in sequence; sometimes paintings are grouped for convenience but vary in execution and tone. The idea for the head series came after he returned penniless, late in 1948, from a stay in Tangier. In the previous three years he had been unable to find a voice; the last surviving canvas from this period is his Painting (1946). Although he continued to paint, he was a ruthless self-critic, given to slashing canvases with blades, and no works survive from between 1947 and the winter of 1948. Gallerist Erica Brausen offered Bacon the opportunity of a solo show for the opening of her new Hanover Gallery. He agreed, but had nothing in reserve to hang. In following years, Brausen became perhaps the most important of Bacon's early champions; she arranged this showinghis debut solo exhibitionpublicised him widely and organised viewings for international buyers.Already 40 years old, Bacon viewed the exhibition as his last chance and applied himself to the task with determination. Because he had destroyed all his output of the last three years, he had little choice but to present new works. He did not have a grand plan when he agreed to the show, but eventually found themes that interested him in his Head I of the previous year, and executed five progressively stronger variants in the final weeks before the November exhibition, completing the series barely in time for the opening.
Question: What is the name of the person who executed five progressively stronger variants in the final weeks before the November exhibition?
Solution: Bacon.
