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.

Question: Passage: Nixon in China is an opera in three acts by John Adams, with a libretto by Alice Goodman. Adams' first opera, it was inspired by U.S. President Richard Nixon's 1972 visit to China. The work premiered at the Houston Grand Opera on October 22, 1987, in a production by Peter Sellars with choreography by Mark Morris. When Sellars approached Adams with the idea for the opera in 1983, Adams was initially reluctant, but eventually decided that the work could be a study in how myths come to be, and accepted the project. Goodman's libretto was the result of considerable research into Nixon's visit, though she disregarded most sources published after the 1972 trip.
To create the sounds he sought, Adams augmented the orchestra with a large saxophone section, additional percussion, and electronic synthesizer. Although sometimes described as minimalist, the score displays a variety of musical styles, embracing minimalism after the manner of Philip Glass alongside passages echoing 19th-century composers such as Wagner and Johann Strauss. With these ingredients, Adams mixes Stravinskian 20th-century neoclassicism, jazz references, and big band sounds reminiscent of Nixon's youth in the 1930s. The combination of these elements varies frequently, to reflect changes in the onstage action.
Following the 1987 premiere, the opera received mixed reviews; some critics dismissed the work, predicting it would soon vanish. However, it has been presented on many occasions since, in both Europe and North America, and has been recorded twice. In 2011, the opera received its Metropolitan Opera debut, a production based on the original sets, and in the same year was given an abstract production in Toronto by the Canadian Opera Company. Recent critical opinion has tended to recognize the work as a significant and lasting contribution to American opera.

Answer: What is the first name of the person who was in China in Adam's opera?


Question: 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.

Answer: What is the name of the entity that provides habitat for juvenile sea animals that have left the shelter of the mangrove belts?


Question: Passage: By the end of the medieval period a complex body of customary law had come into existence dealing with the four "Mendip mineries". That the medieval control was in the hands of the monastic foundations may indicate some continuity of tenure of large-scale holdings, focused on the mines, from the Roman period.William Wilberforce's visit to Cheddar in 1789, during which he saw the poor circumstances of the locals, inspired Hannah More to begin her work improving the conditions of the Mendip miners and agricultural workers. Under her influence, schools were built and children were formally instructed in reading and Christian doctrine. Between 1770 and 1813 some 7,300 ha (18,000 acres) of land on the hills were enclosed, mainly with dry stone walls that today form a key part of the landscape. In 2006 funding was obtained to maintain and improve the walls, which had steadily deteriorated over the years.
Over 300 "Mendip Motor Cars" were built by an engineering works based in Chewton Mendip in the years immediately before and after World War I. In World War II a bombing decoy was constructed on top of Black Down at Beacon Batch in an attempt to confuse bombers aiming to damage the city of Bristol, and piles of stones (known as cairns) were created to prevent enemy aircraft using the hilltop as a landing site.In the 1960s, the tallest mast in the region at 293 metres (961 ft) above ground level, the Mendip UHF television transmitter, was installed on Pen Hill near Wells, one of the highest points of the Mendips. The transmitter's antenna rises to almost 589 metres (1,932 ft) above sea level. Since 2003, arguments have raged over plans to erect a wind turbine near Chewton Mendip. The proposal was initially rejected by Mendip District Council, which enjoyed the support of a range of local groups and organisations, on the grounds that the environmental impact on the edge of the AONB outweighed the nominal amount of electricity which would be generated. In April 2006, however, a planning enquiry gave Ecotricity permission to build a 102 m (335 ft) turbine during the following year.The Mendip Power Group are installing micro-hydroelectric turbines in a number of historic former watermills. The first to start electricity generation was Tellisford Mill, on the River Frome, which began operating in 2006 and produces 50–55 kW. Other mills in the Group, together with initial assessments of their capacity, include: Stowford Mill (37 kW) and Shawford Mill (31 kW), Jackdaws Iron Works (10 kW), Glencot House (5.8 kW), Burcott Mill (5.2 kW), Bleadney Mill (5.4 kW), Coleford Mill (6.6 kW), Old Mill (5.2 kW) and Farrants Mill (9.9 kW).

Answer:
What is the full of the person that influenced Christian doctrine?
