instruction:
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: 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: Celia Crowson and her family go on holiday to the south coast of England in the summer of 1939. Soon afterwards the Second World War breaks out and Celia's father joins what was to become the Home Guard and her more confident sister Phyllis joins the Auxiliary Territorial Service. 
Fearing her father's disapproval if she moves away from home, Celia hesitates about joining up but eventually her call-up papers arrive. Hoping to join the WAAF or one of the other services, Celia instead gets posted to a factory making aircraft components, where she meets her co-workers, including her Welsh room-mate Gwen Price and the vain upper middle class Jennifer Knowles. Knowles dislikes the work they have to do at the factory, causing friction with their supervisor Charlie Forbes which eventually blossoms into a verbally combative romance.
A nearby RAF bomber station sends some of its men to a staff dance at the factory, during which Celia meets and falls in love with an equally shy young Scottish flight sergeant Fred Blake. Their relationship encounters a crisis when Fred refuses to tell Celia when he is sent out on his first mission, but soon afterwards they meet and make up, with Fred asking Celia to marry him. After the wedding they spend their honeymoon at the same south coast resort as the Crowsons went to in 1939, finding it much changed with minefields and barbed wire defending against the expected German invasion.
answer:
What are the first names of the couple who meet and make up?


question:
Passage: The July 2009 Ürümqi riots were a series of violent riots over several days that broke out on 5 July 2009 in Ürümqi, the capital city of the Xinjiang Uyghur Autonomous Region (XUAR), in northwestern People's Republic of China (PRC). The first day's rioting, which involved at least 1,000 Uyghurs, began as a protest but escalated into violent attacks that mainly targeted Han Chinese people. China's People's Armed Police were deployed, and two days later hundreds of Han people clashed with both police and Uyghurs. PRC officials said that a total of 197 people died, among those killed most of them are Hans, with 1,721 others injured and many vehicles and buildings destroyed; however, Uyghur exile groups say the death toll is higher. Many  men disappeared during wide-scale police sweeps in the days following the riots; Human Rights Watch (HRW) documented 43 cases and said figures for real disappearances were likely to be much higher.Rioting began when the police confronted the march calling for a full investigation into the Shaoguan incident, a brawl in southern China several days earlier in which two Uyghurs had been killed. However, observers disagree on what caused the protests to become violent. The PRC central government alleged that the riots themselves were planned from abroad by the World Uyghur Congress (WUC) and its leader Rebiya Kadeer, while Kadeer denies fomenting the violence in her fight for Uyghur "self-determination." Uyghur exile groups claim that the escalation was caused by the police's use of excessive force.Chinese media coverage of the Ürümqi riots was extensive, and was compared favourably to that of the unrest in Tibet in 2008. When the riots began, telephone and internet connections with Xinjiang were cut off. In the weeks that followed, official sources reported that over 1,000 Uyghurs were arrested and detained; Uyghur-run mosques were temporarily closed. The communication limitations and armed police presence remained in place as of January 2010. By November 2009, over 400 individuals faced criminal charges for their actions during the riots. Nine were executed in November 2009, and by February 2010, at least 26 had received death sentences.
answer:
How many people faced criminal charges in November 2009 for the series of violent riots over several days?
