You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Why? 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.

New input: Passage: Sir Michael Kemp Tippett  (2 January 1905 – 8 January 1998) was an English composer who rose to prominence during and immediately after the  Second World War. In his lifetime he was sometimes  ranked with his contemporary Benjamin Britten as one of the leading British composers of the 20th century. Among his best-known works are the oratorio A Child of Our Time, the orchestral Fantasia Concertante on a Theme of Corelli, and the opera The Midsummer Marriage.
Tippett's talent developed slowly. He withdrew or destroyed his earliest compositions, and was 30 before any of his works were published. Until the mid-to-late 1950s his music was broadly lyrical in character, before changing to a more astringent and experimental style. New influences, including those of jazz and blues after his first visit to America in 1965, became increasingly evident in his compositions. While Tippett's stature with the public continued to grow, not all critics approved of these changes in style, some believing that the quality of his work suffered as a consequence. From around 1976 Tippett's late works began to reflect the works of his youth through a return to lyricism. Although he was much honoured in his lifetime, critical judgement on Tippett's legacy has been uneven, the greatest praise being generally reserved for his earlier works. His centenary in 2005 was a muted affair; apart from the few best-known works, his music has been performed  infrequently in the 21st century.
Having briefly embraced communism in the 1930s, Tippett avoided identifying with any political party. A pacifist after 1940, he was imprisoned in 1943 for refusing to carry out war-related duties required by his military exemption. His initial difficulties in accepting his  homosexuality led him in 1939 to Jungian psychoanalysis; the Jungian dichotomy of "shadow" and "light" remained a recurring factor in his music. He was a strong advocate of music education, and was active for much of his life as a radio broadcaster and writer on music.
Solution:
What is the last name of the composer among whose best-known works are the oratorio A Child of Our Time, the orchestral Fantasia Concertante on a Theme of Corelli, and the opera The Midsummer Marriage?
