In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
One example is below.
Q: 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.
A: Who believes Fagin's gang make wallets and handkerchiefs?.
Rationale: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.
Q: Passage: With the South London Orchestra temporarily disbanded because of the war, Tippett returned to teaching at Hazelwood. In October 1940 he accepted the post of Director of Music at Morley College, just after its buildings were almost completely destroyed by a bomb. Tippett's challenge was to rebuild the musical life of the college, using temporary premises and whatever resources he could muster. He revived the Morley College Choir and orchestra, and arranged innovative concert programmes that typically mixed early music (Orlando Gibbons, Monteverdi, Dowland), with contemporary works by Stravinsky, Hindemith and Bartok.
He continued the college's established association with the music of Purcell; a performance in November 1941 of Purcell's Ode to St Cecilia, with improvised instruments and rearrangements of voice parts, attracted considerable attention. The music staff at Morley was augmented by the recruitment of refugee musicians from Europe, including Walter Bergmann, Matyas Seiber, and Walter Goehr who took charge of the college orchestra.A Child of Our Time was finished in 1941 and put aside with no immediate prospects of performance. Tippett's Fantasia on a Theme of Handel for piano and orchestra was performed at the Wigmore Hall in March 1942, with Sellick again the soloist, and the same venue saw the premiere of the composer's String Quartet No. 2 a year later. The first recording of Tippett's music, the Piano Sonata No. 1 played by Sellick, was issued in August 1941. The recording was well received by the critics, Wilfrid Mellers predicting a leading role for the composer in the future of English music. In 1942, Schott Music began to publish Tippett's works, establishing an association that continued until the end of the composer's life.The question of Tippett's liability for war service remained unresolved until mid-1943. In November 1940 he had formalised his pacifism by joining the Peace Pledge Union and applying for registration as a conscientious objector. His case was heard by a tribunal in February 1942, when he was assigned to non-combatant duties. Tippett rejected such work as an unacceptable compromise with his principles and in June 1943, after several further hearings and statements on his behalf from distinguished musical figures, he was sentenced to three months' imprisonment in HM Prison Wormwood Scrubs. He served two months, and although thereafter he was technically liable to further charges for failing to comply with the terms set by his tribunal, the authorities left him alone.
A:
What is the last name of the person who had formalised his pacifism by joining the Peace Pledge Union?
