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.

Let me give you an 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.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is 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.

Passage: Discounting his collaboration with Dukas in the completion of Guiraud's unfinished Frédégonde, Saint-Saëns wrote twelve operas, two of which are opéras comiques. During the composer's lifetime his Henry VIII became a repertory piece; since his death only Samson et Dalila has been regularly staged, although according to Schonberg, Ascanio (1890) is considered by experts to be a much finer work. The critic Ronald Crichton writes that for all his experience and musical skill, Saint-Saëns "lacked the 'nose' of the theatre animal granted, for example, to Massenet who in other forms of music was his inferior". In a 2005 study, the musical scholar Steven Huebner contrasts the two composers: "Saint-Saëns obviously had no time for Massenet's histrionics". Saint-Saëns's biographer James Harding comments that it is regrettable that the composer did not attempt more works of a light-hearted nature, on the lines of La princesse jaune, which Harding describes as like Sullivan "with a light French touch".Although most of Saint-Saëns's operas have remained neglected, Crichton rates them as important in the history of French opera, as "a bridge between Meyerbeer and the serious French operas of the early 1890s". In his view, the operatic scores of Saint-Saëns have, in general, the strengths and weaknesses of the rest of his music – "lucid Mozartian transparency, greater care for form than for content ... There is a certain emotional dryness; invention is sometimes thin, but the workmanship is impeccable." Stylistically, Saint-Saëns drew on a range of models. From Meyerbeer he drew the effective use of the chorus in the action of a piece; for Henry VIII he included Tudor music he had researched in London; in La princesse jaune he used an oriental pentatonic scale; from Wagner he derived the use of leitmotifs, which, like Massenet, he used sparingly. Huebner observes that Saint-Saëns was more conventional than Massenet so far as through composition is concerned, more often favouring discrete arias and ensembles, with less variety of tempo within individual numbers. In a survey of recorded opera Alan Blyth writes that Saint-Saëns "certainly learned much from Handel, Gluck, Berlioz, the Verdi of Aida, and Wagner, but from these excellent models he forged his own style.".
Answer:
What is the last name of the composer whose lack of lighthearted works Harding found regrettable?
