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: In 1978, con artists Irving Rosenfeld and Sydney Prosser have started a relationship, and are working together. Sydney has improved Rosenfeld's scams, posing as English aristocrat "Lady Edith Greensly". Irving loves Sydney, but is hesitant to leave his unstable wife Rosalyn, fearing he will lose contact with his adopted son Danny. Rosalyn has also threatened to report Irving to the police if he leaves her. FBI agent Richie DiMaso catches Irving and Sydney in a loan scam, but offers to release them if Irving can line up four additional arrests. Richie believes Sydney is English, but has proof that her claim of aristocracy is fraudulent. Sydney tells Irving she will manipulate Richie, distancing herself from Irving.
Irving has a friend pretending to be a wealthy Arab sheikh looking for potential investments in America. An associate of Irving's suggests the sheikh do business with Mayor Carmine Polito of Camden, New Jersey, who is campaigning to revitalize gambling in Atlantic City, but has struggled in fund-raising. Carmine seems to have a genuine desire to help the area's economy and his constituents. Richie devises a plan to make Mayor Polito the target of a sting operation, despite the objections of Irving and of Richie's boss, Stoddard Thorsen. Sydney helps Richie manipulate an FBI secretary into making an unauthorized wire transfer of $2,000,000. When Stoddard's boss, Anthony Amado, hears of the operation, he praises Richie's initiative, pressuring Stoddard to continue.
Who is the boss of Richie's boss?

Passage: The open waters are inhabited by fishes, molluscs and crustaceans living on sea grasses or who prey on each other. The shallowness of the lagoon makes it suitable habitat for diving birds such as anhinga, cormorants and diving ducks. The bay also provides habitat for juvenile sea animals that have left the shelter of the mangrove belts.  Manatees frequent the quiet waters of the bay. The bay has a year-round population of double-crested cormorants. Winter residents include northern gannets, American white pelicans and common loons. The bay also has a resident population of common bottlenose dolphins.Biscayne Bay is a shallow lagoon with little vertical density or salinity gradient due to its lack of depth. Instead of a vertical gradient, the bay shows a horizontal density gradient, with fresh water entering from the drainage canals on the west side and seawater entering through gaps in the keys and through the safety valve section of shoals. Bay salinity reaches a peak in June. Changes in the salinity pattern of the bay have had negative effects on formerly abundant species such as red drum. Biscayne Bay and Florida Bay are major nurseries for red grouper and gray snapper. The bottom of the lagoon hosts sponges and soft corals in places where grasses cannot not grow. Three primary species of seagrass are found in the park: turtlegrass, shoal grass and manatee grass. The endangered Johnson's seagrass is also found in small quantities in the bay, which is at the southern end of the grass's range. Roughly 75 percent of the central bay floor is covered by grasses. Scarring of seagrass beds by vessel groundings or propellers is a significant problem. About 200 such incidents are documented each year, with full re-growth requiring up to 15 years. The bay is also affected by commercial shrimp trawling, which is permitted in park waters.  The passage of roller-frame trawl nets does not harm grasses, but damages soft corals and sponges.
What is the name of the entity that provides habitat for juvenile sea animals that have left the shelter of the mangrove belts?

Passage: From 1837, Alkan lived in the Square d'Orléans in Paris, which was inhabited by numerous celebrities of the time including Marie Taglioni, Alexandre Dumas, George Sand, and Chopin. Chopin and Alkan were personal friends and often discussed musical topics, including a work on musical theory that Chopin proposed to write. By 1838, at 25 years old, Alkan had reached a peak of his career. He frequently gave recitals, his more mature works had begun to be published, and he often appeared in concerts with Liszt and Chopin. On 23 April 1837 Alkan took part in Liszt's farewell concert in Paris, together with the 14-year-old César Franck and the virtuoso Johann Peter Pixis. On 3 March 1838, at a concert at the piano-maker Pape, Alkan played with Chopin, Zimmerman, and Chopin's pupil Adolphe Gutmann in a performance of Alkan's transcription, now lost, of two movements of Beethoven's Seventh Symphony for two pianos, eight hands.At this point, for a period which coincided with the birth and childhood of his natural son, Élie-Miriam Delaborde (1839–1913), Alkan withdrew into private study and composition for six years, returning to the concert platform only in 1844.  Alkan neither asserted nor denied his paternity of Delaborde, which, however, his contemporaries seemed to assume. Marmontel wrote cryptically in a biography of Delaborde that "[his] birth is a page from a novel in the life of a great artist". Alkan gave early piano lessons to Delaborde, who was to follow his natural father as a keyboard virtuoso.Alkan's return to the concert platform in 1844 was greeted with enthusiasm by critics, who noted the "admirable perfection" of his technique, and lauded him as "a model of science and inspiration", a "sensation" and an "explosion". They also commented on the attending celebrities including Liszt, Chopin, Sand and Dumas. In the same year he published his piano étude Le chemin de fer, which critics, following Ronald Smith, believe to be the first representation in music of a steam engine. Between 1844 and 1848 Alkan produced a series of virtuoso pieces, the 25 Préludes Op. 31 for piano or organ, and the sonata Op. 33 Les quatre âges. Following an Alkan recital in 1848, the composer Giacomo Meyerbeer was so impressed that he invited the pianist, whom he considered "a most remarkable artist", to prepare the piano arrangement of the overture to his forthcoming opera, Le prophète. Meyerbeer heard and approved Alkan's arrangement of the overture for four hands (which Alkan played with his brother Napoléon) in 1849; published in 1850, it is the only record of the overture, which was scrapped during rehearsals at the Opéra.

What is the first name of the brother of the man who neither asserted nor denied his paternity of Delaborde?
