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: Temperley writes: "After 1855 [Bennett] was spurred by belated honours, and occasional commissions, to compose a respectable number of significant and substantial works, though it was too late to recapture his early self-confidence." Works from his later years included the cello Sonata Duo for Piatti; a pastoral cantata, The May Queen, Op. 39, for the opening of the Leeds Town Hall in 1858; an Ode (Op. 40) with words by Alfred, Lord Tennyson for the opening of the 1862 International Exhibition in London; an Installation Ode for Cambridge University (Op. 41) with words by Charles Kingsley, which included a lament for the late Prince Albert; a symphony in G minor (Op. 43); a sacred cantata,The Woman of Samaria for the Birmingham Triennial Music Festival of 1867; and finally a second Piano Sonata (The Maid of Orleans, Op. 46). Many of these works were composed during his summer holidays which were spent at Eastbourne. The Ode for the Exhibition was the cause of a further imbroglio with Costa, who although in charge of music for the Exhibition refused to conduct anything by Bennett. Eventually it was conducted by Prosper Sainton, between works by Meyerbeer and Daniel Auber also commissioned for the occasion. The affair leaked into the press, and Costa was widely condemned for his behaviour.In March 1856 Bennett, while still teaching at the RAM and Queen's College, was elected Professor of Music at the University of Cambridge. He modernised the system of awarding music degrees, instituting viva voce examinations and requiring candidates for doctorates to first take the degree of Bachelor of Music. Two years later on 8 June 1868 the newly formed (later Royal) College of Organists awarded him an Honorary Fellowship.In 1858 came yet another clash involving Costa, when the autocratic Earl of Westmorland, the original founder of the RAM, saw fit to arrange a subscription concert for the Academy to include a Mass of his own composition, to be conducted by Costa and using the orchestra and singers of the Opera, over the heads of the Academy directors. Bennett resigned from the RAM at this overbearing behaviour, and was not to return until 1866. Towards the end of 1862 Bennett's wife died after a painful illness. His biographer W. B. Squire suggests that "he never recovered from the effects of Mrs. Bennett's death, and that henceforward a painful change in him became apparent to his friends." In 1865 Bennett again visited Leipzig where he was reunited with old friends including Ferdinand David, and his Op. 43 Symphony was performed. 
Question: What is the last name of the man who wrote that the musician who composed during his summer holidays "...never recovered from the effects of Mrs. Bennett's death"?
Example Output: Squire.

Example Input: Passage: Minnesota has some of the earth's oldest rocks, gneisses that are about 3.6 billion years old (80% as old as the planet). About 2.7 billion years ago, basaltic lava poured out of cracks in the floor of the primordial ocean; the remains of this volcanic rock formed the Canadian Shield in northeast Minnesota. The roots of these volcanic mountains and the action of Precambrian seas formed the Iron Range of northern Minnesota. Following a period of volcanism 1.1 billion years ago, Minnesota's geological activity has been more subdued, with no volcanism or mountain formation, but with repeated incursions of the sea, which left behind multiple strata of sedimentary rock.In more recent times, massive ice sheets at least one kilometer thick ravaged the state's landscape and sculpted its terrain. The Wisconsin glaciation left 12,000 years ago. These glaciers covered all of Minnesota except the far southeast, an area characterized by steep hills and streams that cut into the bedrock. This area is known as the Driftless Zone for its absence of glacial drift. Much of the remainder of the state outside the northeast has 50 feet (15 m) or more of glacial till left behind as the last glaciers retreated. Gigantic Lake Agassiz formed in the northwest 13,000 years ago. Its bed created the fertile Red River valley, and its outflow, glacial River Warren, carved the valley of the Minnesota River and the Upper Mississippi downstream from Fort Snelling. Minnesota is geologically quiet today; it experiences earthquakes infrequently, and most of them are minor. 
Question: What is the name of the area in Minnesota was not covered by massive ice sheets?
Example Output: the Driftless Zone.

Example Input: Passage: After leaving the army in January 1919, Grainger refused an offer to become conductor of the Saint Louis Symphony Orchestra and  resumed his career as a concert pianist.  He  was soon performing around 120 concerts a year, generally to great critical acclaim, and in  April 1921 reached a wider audience by performing in a cinema, New York's Capitol Theatre. Grainger  commented that the huge audiences at these cinema concerts often showed greater appreciation for his playing than those at established concert venues such as Carnegie Hall and the Aeolian. In the summer of 1919 he led a course in piano technique at Chicago Musical College, the first of many such educational duties he would undertake in later years.Amid his concert and teaching duties, Grainger found time to re-score many of his works (a habit he continued throughout his life) and also to compose new pieces: his Children's March: Over the Hills and Far Away, and the orchestral version of The Power of Rome and the Christian Heart both originated in this period.   He also began to develop the technique of elastic scoring, a form of flexible orchestration  which enabled works to be  performed by different numbers of players and instrument types, from small chamber groups  up to full orchestral strength.In April 1921 Grainger moved with his mother to a large house in White Plains, New York. This was  his  home for the remainder of his life. From the beginning of 1922 Rose's health deteriorated sharply; she was suffering from  delusions and nightmares, and became  fearful that her illness would harm her son's career. Because of the closeness of the bond between the two, there had long been  rumours that  their relationship was incestuous;  in April 1922 Rose was directly challenged over this issue by her friend Lotta Hough. From her last letter to Grainger, dated 29 April, it seems that this confrontation unbalanced Rose; on 30 April, while Grainger was touring on the West Coast, she jumped to her death from an office window  on the 18th floor of the Aeolian Building in New York City. The letter, which began "I am out of my mind and cannot think properly", asked Grainger if he had ever spoken to Lotta of "improper love". She signed the letter: "Your poor insane mother". 
Question: What is the last name of the individual about whom Grangier was asked if he had ever spoken to her of "improper love"?
Example Output:
Hough.
