TASK DEFINITION: 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.
PROBLEM: 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.

SOLUTION: Who established a curfew and cancelled plans for a Chinese festival?

PROBLEM: Passage: Before dawn on September 13, 1964, the ruling military junta of South Vietnam, led by General Nguyễn Khánh, was threatened by a coup attempt headed by Generals Lâm Văn Phát and Dương Văn Đức, who sent dissident units into the capital Saigon. They captured various key points and announced over national radio the overthrow of the incumbent regime. With the help of the Americans, Khánh was able to rally support and the coup collapsed the next morning without any casualties.
In the immediate month leading up the coup, Khánh's leadership had become increasingly troubled. He had tried to augment his powers by declaring a state of emergency, but this only provoked large-scale protests and riots calling for an end to military rule, with Buddhist activists at the forefront. Fearful of losing power, Khánh began making concessions to the protesters and promised democracy in the near future. He also removed several military officials closely linked to the discriminatory Catholic rule of the slain former President Ngô Đình Diệm; this response to Buddhist pressure dismayed several Catholic officers, who made a few abortive moves to remove him from power.
In part because of pressure from Buddhist protests, Khánh removed the Catholics Phát and Đức from the posts of Interior Minister and IV Corps commander, respectively. They responded with a coup supported by the Catholic-aligned Đại Việt Quốc dân đảng, as well as General Trần Thiện Khiêm, a Catholic who had helped Khánh to power. Having captured the radio station, Phát then made a broadcast promising to revive Diệm's policies. Khánh managed to evade capture and, during the first stage of the coup, there was little activity as most senior officers failed to support either side. Throughout the day, Khánh gradually rallied more allies and the U.S. remained supportive of his rule and pressured the rebels to give up. With the backing of Air Marshal Nguyễn Cao Kỳ, commander of the Republic of Vietnam Air Force, and General Nguyễn Chánh Thi, Khánh was able to force Phát and Đức to capitulate the next morning, September 14. Đức, Kỳ and Thi then appeared at a media conference where they denied that any coup had taken place and put on a choreographed display of unity, claiming that nobody would be prosecuted over the events.

SOLUTION: What was the first name of the person who was able to rally support and the coup collapsed the next morning without any casualties?

PROBLEM: Passage: The whale ear has specific adaptations to the marine environment. In humans, the middle ear works as an impedance equalizer between the outside air's low impedance and the cochlear fluid's high impedance. In whales, and other marine mammals, there is no great difference between the outer and inner environments. Instead of sound passing through the outer ear to the middle ear, whales receive sound through the throat, from which it passes through a low-impedance fat-filled cavity to the inner ear. The whale ear is acoustically isolated from the skull by air-filled sinus pockets, which allow for greater directional hearing underwater. Odontocetes send out high frequency clicks from an organ known as a melon. This melon consists of fat, and the skull of any such creature containing a melon will have a large depression. The melon size varies between species, the bigger the more dependent they are of it. A beaked whale for example has a small bulge sitting on top of its skull, whereas a sperm whale's head is filled up mainly with the melon.The whale eye is relatively small for its size, yet they do retain a good degree of eyesight. As well as this, the eyes of a whale are placed on the sides of its head, so their vision consists of two fields, rather than a binocular view like humans have. When belugas surface, their lens and cornea correct the nearsightedness that results from the refraction of light; they contain both rod and cone cells, meaning they can see in both dim and bright light, but they have far more rod cells than they do cone cells. Whales do, however, lack short wavelength sensitive visual pigments in their cone cells indicating a more limited capacity for colour vision than most mammals. Most whales have slightly flattened eyeballs, enlarged pupils (which shrink as they surface to prevent damage), slightly flattened corneas and a  tapetum lucidum; these adaptations allow for large amounts of light to pass through the eye and, therefore, a very clear image of the surrounding area. They also have glands on the eyelids and outer corneal layer that act as protection for the cornea.The olfactory lobes are absent in toothed whales, suggesting that they have no sense of smell. Some whales, such as the bowhead whale, possess a vomeronasal organ, which does mean that they can "sniff out" krill.Whales are not thought to have a good sense of taste, as their taste buds are atrophied or missing altogether.  However, some toothed whales have preferences between different kinds of fish, indicating some sort of attachment to taste. The presence of the Jacobson's organ indicates that whales can smell food once inside their mouth, which might be similar to the sensation of taste.

SOLUTION:
What is the name of the organ in the mouth of the animals that have slightly flattened eyeballs that allows them to smell in their mouths?
