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: 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: Even in his own homeland the general public was slow to recognise Smetana. As a young composer and pianist he was well regarded in Prague musical circles, and had the approval of Liszt, Proksch and others, but the public's lack of acknowledgement was a principal factor behind his self-imposed exile in Sweden. After his return he was not taken particularly seriously, and was hard put to get audiences for his new works, hence his "prophet without honour" remark after the nearly empty hall and indifferent reception of Richard III and Wallenstein's Camp at Žofín Island in January 1862.Smetana's first noteworthy public success was his initial opera The Brandenburgers in Bohemia, in 1866 when he was already 42 years old. His second opera, The Bartered Bride, survived the unfortunate mistiming of its opening night and became an enduring popular triumph. The different style of his third opera, Dalibor, closer to that of Wagnerian music drama, was not readily understood by the public and was condemned by critics who believed that Czech opera should be based on folk-song. It disappeared from the repertory after only a handful of performances. Thereafter the machinations that accompanied Smetana's tenure as Provisional Theatre conductor restricted his creative output until 1874.
In his final decade, the most fruitful of his compositional career despite his deafness and increasing ill-health, Smetana belatedly received national recognition. Of his later operas, The Two Widows and The Secret were warmly received, while The Kiss was greeted by an "overwhelming ovation". The ceremonial opera Libuše was received with thunderous applause for the composer; by this time (1881) the disputes around his music had declined, and the public was ready to honour him as the founder of Czech music. Nevertheless, the first few performances in October 1882 of an evidently under-rehearsed The Devil's Wall were chaotic, and the composer was left feeling "dishonoured and dispirited." This disappointment was swiftly mitigated by the acclaim that followed the first performance of the complete Má vlast cycle in November: "Everyone rose to his feet and the same storm of unending applause was repeated after each of the six parts ... At the end of Blaník [the final part] the audience was beside itself and the people could not bring themselves to take leave of the composer.".
What is the last name of the person who was left feeling dishonoured and dispirited?

Passage: Lancaster was born in London in 1908, the only child of Robert Lancaster (1880–1917) and his wife, Clare Bracebridge, née Manger. His paternal grandfather, Sir William Lancaster, rose from modest beginnings to become the chief executive of the Prudential Assurance Company, Lord of the manor of East Winch, Norfolk, and a philanthropist in the field of education. Osbert's mother was an artist, known for her paintings of flowers, who had exhibited regularly at the Royal Academy; his father was a publisher, who volunteered for the army on the outbreak of the First World War, was commissioned as a second lieutenant in the Norfolk Regiment, and was killed at the Battle of Arras in April 1917.
Elgin Crescent, Notting Hill, where Lancaster was born and raised, was an upper-middle class area. The family maintained a staff of servants, including a cook and a nurse. Such was the mixed nature of London in the early years of the 20th century that a short distance away were the deprived and dangerous Notting Dale and the Portobello Road, where, as Lancaster recalled in his 1953 memoirs, it was said to be impossible for a well-dressed man to walk and emerge intact. From an early age Lancaster was aware of the variety of classes, nationalities, and social attitudes around him.In 1918 Lancaster was sent to St Ronan's preparatory school, Worthing. The régime at the school leaned heavily towards sport, in which he was neither interested nor proficient. The headmaster, Stanley Harris, was a celebrated amateur footballer and occasional first class cricketer, but he was reasonably tolerant of Lancaster's disdain for games, and on the whole Lancaster enjoyed his time at the school. His education there was, he later commented, of more importance to him than anything he learned later in his school and university career. He left St Ronan's in 1921, aged thirteen, and went to Charterhouse, where his father and uncles had all been sent. There he was shocked by the bullying and bad language, but in addition to its sporty, philistine "bloods", the school had an intellectual and aesthetic tradition. Lancaster's biographer Richard Boston writes, "The hearty Baden-Powell, for example, was offset by Ralph Vaughan Williams and Robert Graves, while talented Carthusian artists had included Thackeray, Leech, Lovat Fraser and Max Beerbohm". The art master, P. J. ("Purple") Johnson, encouraged Lancaster, insisting that a sound technique was a prerequisite for effective self-expression in drawing or painting; in that respect the boy's time at the school was valuable, though otherwise the headmaster found him "irretrievably gauche ... a sad disappointment". Lancaster shared Beerbohm's view that being an old boy of the school was more pleasurable than being a pupil there.

What is the full name of the person married to the son of the man who rose to become chief executive of the Prudential Assurance Company?
