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 Input: Passage: Ottavio's marriage troubled Alessandro; he struggled with the burden of chastity and entertained fantasies of marrying a princess. He resented his younger brother's arrangement; during the wedding ceremony he "became more deathly pale than death itself, and, so they say, is unable to bear this thing, that he, the first-born, should see himself deprived of such splendid status and of the daughter of an Emperor." In 1546 Paul gave Pier Luigi the duchies of Parma and Piacenza as papal fiefs, a highly political move by the pope: in doing so he gave titles and wealth to Pier and appointed a lord who was subservient and owed a debt of gratitude, guaranteeing that the duchies would remain under papal control. At the same time, Ottavio was posted to the North of Italy to support Charles. By 1546 Ottavio was 22 years old, married to Margaret of Austria and an accomplished and distinguished individual. In 1547 his father was assassinated and Ottavio claimed the dukedom of Parma and Piacenza against the express wishes of both Charles, his father-in-law, and Paul. In doing so, Ottavio acted in opposition to the pope's desire to maintain the duchies as papal fiefs, and to Charles, whom he believed responsible for the plot to assassinate Pier Luigi.Titian was a personal friend of Charles; the commissioning of the portrait was most likely intended by Paul as a signal of allegiance to the emperor. Pressure from reforming monarchs in France and Spain, coupled with a general shift of influence in France's favour, ended the Farnese hold on the papacy soon after Paul's death. Ottavio excelled as a military commander and was awarded the Golden Fleece by the emperor. While the post had been given as a means to strengthen the family position, it did not come without cost. His success bred resentment amongst his family, as he began to see himself unaccountable to Rome.At the time of the portrait Paul had convinced Alessandro to retain the post, hinting that he would later succeed him as pope – an aspiration that was ultimately frustrated. As Alessandro realised the emptiness of the promise he lost confidence in both his grandfather's word and political credibility. 
Question: What was the name of Alessandro's brother?
Example Output: Ottavio.

Example Input: Passage: In October, MacDonald introduced Thomson to Dr. James MacCallum. A frequent visitor to the Ontario Society of Artists' (OSA) exhibitions, MacCallum was admitted to the Arts and Letters Club in January 1912. There, he met artists such as John William Beatty, Arthur Heming, MacDonald and Harris. MacCallum eventually persuaded Thomson to leave Rous and Mann and start a painting career. In October 1913, MacCallum introduced Thomson to A. Y. Jackson, later a founder of the Group of Seven. MacCallum recognized Thomson's and Jackson's talents and offered to cover their expenses for one year if they committed themselves to painting full time. MacCallum and Jackson both encouraged Thomson to "take up painting seriously, [but] he showed no enthusiasm. The chances of earning a livelihood by it did not appear to him promising. He was sensitive and independent, and feared he might become an object of patronage." MacCallum wrote that when he first saw Thomson's sketches, he recognized their "truthfulness, their feeling and their sympathy with the grim fascinating northland ... they made me feel that the North had gripped Thomson as it had gripped me since I was eleven when I first sailed and paddled through its silent places." He described Thomson's paintings as "dark, muddy in colour, tight and not wanting in technical defects". After Thomson's death, MacCallum helped preserve and advocate for his work.Thomson accepted MacCallum's offer under the same terms offered to Jackson. He travelled around Ontario with his colleagues, especially to the wilderness of Ontario, which was to become a major source of inspiration. Regarding Algonquin Park, he wrote in a letter to MacCallum: "The best I can do does not do the place much justice in the way of beauty." He ventured to rural areas near Toronto and tried to capture the surrounding nature. He may have worked as a fire ranger on the Mattagami reserve. Addison and Little suggest that he guided fishing tours, although Hill finds this unlikely since Thomson had only spent a few weeks in the Park the previous year. Thomson became as familiar with logging scenes as with nature in the Park and painted them both.While returning to Toronto in November 1912, Thomson stopped in Huntsville. The visit was possibly to meet with Winfred Trainor, a woman whose family owned a cottage on Canoe Lake in Algonquin Park. Trainor was later rumoured to have been engaged to Thomson with a wedding planned for the late 1917, although little is known about their relationship.Thomson first exhibited with the OSA in March 1913, selling his painting Northern Lake (1912–13) to the Ontario Government for $250 (equivalent to CAD$5,600 in 2018). The sale afforded him time to paint and sketch through the summer and fall of 1913. 
Question: What was the last name of the person who was a founder of the Group of Seven?
Example Output: Jackson.

Example Input: 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 showing—his debut solo exhibition—publicised 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?
Example Output:
Bacon.
