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.

Example input: 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.
Example output: Who believes Fagin's gang make wallets and handkerchiefs?.
Example explanation: 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: By December 1899, Tosca was in rehearsal at the Teatro Costanzi. Because of the Roman setting, Ricordi arranged a Roman premiere for the opera, even though this meant that Arturo Toscanini could not conduct it as Puccini had hoped—Toscanini was fully engaged at La Scala in Milan. Leopoldo Mugnone was appointed to conduct. The accomplished (but temperamental) soprano Hariclea Darclée was selected for the title role; Eugenio Giraldoni, whose father had originated many Verdi roles, became the first Scarpia. The young Enrico Caruso had hoped to create Cavaradossi, but was passed over in favour of the more experienced Emilio De Marchi. The performance was to be directed by Nino Vignuzzi, with stage designs by Adolfo Hohenstein.At the time of the premiere, Italy had experienced political and social unrest for several years. The start of the Holy Year in December 1899 attracted the religious to the city, but also brought threats from anarchists and other anticlericals. Police received warnings of an anarchist bombing of the theatre, and instructed Mugnone (who had survived a theatre bombing in Barcelona), that in an emergency he was to strike up the royal march. The unrest caused the premiere to be postponed by one day, to 14 January.By 1900, the premiere of a Puccini opera was a national event. Many Roman dignitaries attended, as did Queen Margherita, though she arrived late, after the first act. The Prime Minister of Italy, Luigi Pelloux was present, with several members of his cabinet. A number of Puccini's operatic rivals were there, including Franchetti, Pietro Mascagni, Francesco Cilea and Ildebrando Pizzetti. Shortly after the curtain was raised there was a disturbance in the back of the theatre, caused by latecomers attempting to enter the auditorium, and a shout of "Bring down the curtain!", at which Mugnone stopped the orchestra. A few moments later the opera began again, and proceeded without further disruption.The performance, while not quite the triumph that Puccini had hoped for, was generally successful, with numerous encores. Much of the critical and press reaction was lukewarm, often blaming Illica's libretto. In response, Illica condemned Puccini for treating his librettists "like stagehands" and reducing the text to a shadow of its original form. Nevertheless, any public doubts about Tosca soon vanished; the premiere was followed by twenty performances, all given to packed houses.
A:
What is the full name of the name of the Prime Minister that attended the opera that was delayed due to a possible bomb threat?
