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.

Passage: A five-movement ballet occurred somewhere in Act II, staged by W. H. Payne. A heading in the libretto, "Chorus and Ballet", attaches it to the last section of the finale but does not indicate how it figured in the plot. Most press accounts placed it at about this point, although some placed it slightly earlier in the act. At some performances, the ballet was performed in Act I, but it was certainly in Act II on opening night, and it seems finally to have settled there.In 1990, Roderick Spencer and Selwyn Tillett discovered the ballet from Act II of Thespis. Two of the five movements, in the same hand that had copied the score of "Climbing over rocky mountain", were found together with the surviving performance materials for Sullivan's 1864 ballet, L'Île Enchantée. Another section was found in the material for his 1897 ballet, Victoria and Merrie England. The page numbering of the surviving three sections gave approximate lengths for the missing pieces, and a contemporary engraving, seen at left, along with other circumstantial evidence, allowed plausible identifications of the two remaining movements: a dragon costume, used nowhere in the libretto, is presumably from the ballet, and the harp visible in the orchestra pit was an unusual instrument for the Gaiety's orchestra. Movements of appropriate length that made sense of these oddities were found in Sullivan's other ballets, and the reconstructed ballet has been recorded twice on CD.
Sullivan tended to re-use his ballet music. Of the five movements that Tillett and Spencer identified, only one (the Waltz, No. 3) is not known to have been used in any other work. Three of the movements had previously been used in L'Île Enchantée. Two of those, and one other, were eventually re-used in Victoria and Merrie England. One was also used in his incidental music to Macbeth. Sullivan was asked in 1889 to supply a ballet for a French-language production of The Mikado in Brussels, which he duly did. Tillett suggests that the Thespis ballet was almost certainly the music that Sullivan provided, given that it was the only ballet that he wrote for use in an opera, and that three weeks after producing The Gondoliers he is unlikely to have written something original.
answer:
What were the name of the two movements discovered by Spencer and Tillett?


question:
Passage: After groups of Chinese sugar mill workers revolted using custom-made weapons to loot and burn mills, hundreds of ethnic Chinese, suspected to have been led by Kapitein Nie Hoe Kong, killed 50 Dutch soldiers in Meester Cornelis (now Jatinegara) and Tanah Abang on 7 October. In response, the Dutch sent 1,800 regular troops, accompanied by schutterij (militia) and eleven battalions of conscripts to stop the revolt; they established a curfew and cancelled plans for a Chinese festival. Fearing that the Chinese would conspire against the colonials by candlelight, those inside the city walls were forbidden to light candles and were forced to surrender everything "down to the smallest kitchen knife". The following day the Dutch repelled an attack by up to 10,000 ethnic Chinese, led by groups from nearby Tangerang and Bekasi, at the city's outer walls; Raffles wrote that 1,789 Chinese died in this attack. In response, Valckenier called another meeting of the council on 9 October.Meanwhile, rumours spread among the other ethnic groups in Batavia, including slaves from Bali and Sulawesi, Bugis, and Balinese troops, that the Chinese were plotting to kill, rape, or enslave them. These groups pre-emptively burned houses belonging to ethnic Chinese along Besar River. The Dutch followed this with an assault on Chinese settlements elsewhere in Batavia in which they burned houses and killed people. The Dutch politician and critic of colonialism W. R. van Hoëvell wrote that "pregnant and nursing women, children, and trembling old men fell on the sword. Defenseless prisoners were slaughtered like sheep".Troops under Lieutenant Hermanus van Suchtelen and Captain Jan van Oosten, a survivor from Tanah Abang, took station in the Chinese district: Suchtelen and his men positioned themselves at the poultry market, while van Oosten's men held a post along the nearby canal. At around 5:00 p.m., the Dutch opened fire on Chinese-occupied houses with cannon, causing them to catch fire. Some Chinese died in the burning houses, while others were shot upon leaving their homes or committed suicide in desperation. Those who reached the canal near the housing district were killed by Dutch troops waiting in small boats, while other troops searched in between the rows of burning houses, killing any survivors they found. These actions later spread throughout the city. Vermeulen notes that many of the perpetrators were sailors and other "irregular and bad elements" of society. During this period there was heavy looting and seizures of property.
answer:
Who established a curfew and cancelled plans for a Chinese festival?


question:
Passage: Two kinds of wet prairies thrive in the Everglades: marl and water-marsh community. Wet prairies are slightly elevated like sawgrass marshes, but contain abundant plant diversity.  Marl prairies are located where marl covers limestone that may protrude as pinnacles or erode into solution holes: depressions formed by the same processes that create sinkholes. Solution holes, however, do not meet the water table; they are filled with rain water. The surface is covered only three to seven months of the year, but the water is usually just 4 inches (10 cm) deep. Marl is created by layers of periphyton loosely attached to the limestone, and forms a grey or white crumbly mud when it dries. When flooded, the marl can support a variety of water plants, and dwarf cypresses may grow for hundreds of years though not exceed 10 feet (3.0 m) in height. Solution holes may remain flooded even when the prairies are dry, and they support aquatic invertebrates such as crayfish and snails, as well as larval amphibians which feed young wading birds. Where the predominant soil is peat, a water-marsh community exists. Its hydroperiod is longer than the marl prairie, although its plants are less diverse. These regions tend to be on the border between sloughs and sawgrass marshes.
Alligators have created an ecological niche in wet prairies; they dig at low spots with their claws and snouts and create ponds free of vegetation that remain submerged throughout the dry season. Alligator holes are integral to the survival of aquatic invertebrates, turtles, fish, small mammals, and birds during extended drought periods. Alligators feed upon animals that visit the hole.
answer:
What prairies' surface is covered only three to seven months of the year?
