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.

Input: Consider Input: Passage: A tsunami is an unusual form of wave caused by an infrequent powerful event such as an underwater earthquake or landslide, a meteorite impact, a volcanic eruption or a collapse of land into the sea. These events can temporarily lift or lower the surface of the sea in the affected area, usually by a few feet. The potential energy of the displaced seawater is turned into kinetic energy, creating a shallow wave, a tsunami, radiating outwards at a velocity proportional to the square root of the depth of the water and which therefore travels much faster in the open ocean than on a continental shelf. In the deep open sea, tsunamis have wavelengths of around 80 to 300 miles (130 to 480 km), travel at speeds of over 600 miles per hour (970 km/hr) and usually have a height of less than three feet, so they often pass unnoticed at this stage. In contrast, ocean surface waves caused by winds have wavelengths of a few hundred feet, travel at up to 65 miles per hour (105 km/h) and are up to 45 feet (14 metres) high.A trigger event on the continental shelf may cause a local tsunami on the land side and a distant tsunami that travels out across the ocean. The energy of the wave is dissipated only gradually, but is spread out over the wave front, so as the wave radiates away from the source, the front gets longer and the average energy reduces, so distant shores will, on average, be hit by weaker waves. However, as the speed of the wave is controlled by the water depth, it does not travel at the same speed in all directions, and this affects the direction of the wave front - an effect known as refraction - which can focus the strength of the advancing tsunami on some areas and weaken it in others according to undersea topography.
As a tsunami moves into shallower water its speed decreases, its wavelength shortens and its amplitude increases enormously, behaving in the same way as a wind-generated wave in shallow water, but on a vastly greater scale.  Either the trough or the crest of a tsunami can arrive at the coast first. In the former case, the sea draws back and leaves subtidal areas close to the shore exposed which provides a useful warning for people on land. When the crest arrives, it does not usually break but rushes inland, flooding all in its path. Much of the destruction may be caused by the flood water draining back into the sea after the tsunami has struck, dragging debris and people with it. Often several tsunami are caused by a single geological event and arrive at intervals of between eight minutes and two hours. The first wave to arrive on shore may not be the biggest or most destructive.  Occasionally, a tsunami may transform into a bore, typically in a shallow bay or an estuary.

Output: What two types of tsunami's can a trigger event on the continental shelf cause?


Input: Consider Input: Passage: Diamandis released 11 music videos through YouTube during the promotional campaign for Electra Heart. She claimed that their production led her record label into bankruptcy, but stated that they would be released and "finish this era the way I want to." The first, titled "Part 1: Fear and Loathing", was released on 8 August 2011, and sees Diamandis cutting her long brown hair and singing the track on a balcony during the nighttime. It was followed by "Part 2: Radioactive" on 22 August, which depicts a blonde-wigged Diamandis travelling across the United States with her romantic interest. The track was released through the iTunes Store on 23 September, and peaked at number 25 on the UK Singles Chart on 15 October. The black-and-white clip "Part 3: The Archetypes" shows the close-up of a blonde Diamandis while the introduction of "The State of Dreaming" is played; it introduced the archetypes "housewife", "beauty queen", "homewrecker", and "idle teen" on 15 December. "Part 4: Primadonna" served as the music video for the lead single from the record on 12 March 2012.Uploaded on 18 May, the black-and-white "Part 5: Su-Barbie-A" is set to the introduction of "Valley of the Dolls" with overlapped commentary mentioning "Quick-Curl Barbie" and "Mod-Hair Ken"; it depicts Diamandis standing on the porch of a house with her back to the front door. It was followed by "Part 6: Power & Control" on 30 May, where Diamandis is seen engaging in a series of mind games with her romantic interest. Diamandis alleged that Atlantic Records delayed the premiere of "Part 7: How to Be a Heartbreaker" because they felt she was "ugly" in the clip; it was made publicly available on 28 September, and sees Diamandis interacting with several shirtless men in a community shower. "Part 8: E.V.O.L." introduced the previously-unreleased track "E.V.O.L" on 14 February 2013. The black-and-white visual shows a brown-wigged Diamandis looking about a room with white-tiled walls."Part 9: The State of Dreaming", premiered on 2 March, presents Diamandis lying on a bed while "alternating between sad eyes and a big smile". It begins with a black-and-white filter, although transitions into color after the first minute. It was followed by "Part 10: Lies" on 17 July, and employs a similar black-and-white to color technique. Diamandis is first seen looking into the camera wearing little makeup, and is later shown walking into the woods and sitting at a dinner table in the rain. The final music video "Part 11: Electra Heart" introduced the previously-unreleased title track; the clip itself contains footage from the earlier music videos. It symbolically ended the promotional era for Electra Heart, with Diamandis having tweeted "Goodbye, Electra Heart!" on 8 August, the same day the video was released.

Output: What archetypes did part 3 introduce?


Input: Consider Input: Passage: In the 1960s, the ascendant Khmer Rouge forged an alliance with ethnic minorities in Ratanakiri, exploiting Khmer Loeu resentment of the central government. The Communist Party of Kampuchea headquarters was moved to Ratanakiri in 1966, and hundreds of Khmer Loeu joined CPK units. During this period, there was also extensive Vietnamese activity in Ratanakiri. Vietnamese communists had operated in Ratanakiri since the 1940s; at a June 1969 press conference, Sihanouk said that Ratanakiri was "practically North Vietnamese territory". Between March 1969 and May 1970, the United States undertook a massive covert bombing campaign in the region, aiming to disrupt sanctuaries for communist Vietnamese troops. Villagers were forced outside of main towns to escape the bombings, foraging for food and living on the run with the Khmer Rouge. In June 1970, the central government withdrew its troops from Ratanakiri, abandoning the area to Khmer Rouge control. The Khmer Rouge regime, which had not initially been harsh in Ratanakiri, became increasingly oppressive.  The Khmer Loeu were forbidden from speaking their native languages or practicing their traditional customs and religion, which were seen as incompatible with communism. Communal living became compulsory, and the province's few schools were closed. Purges of ethnic minorities increased in frequency, and thousands of refugees fled to Vietnam and Laos. Preliminary studies indicate that bodies accounting for approximately 5% of Ratanakiri's residents were deposited in mass graves, a significantly lower rate than elsewhere in Cambodia.After the Vietnamese defeated the Khmer Rouge in 1979, government policy toward Ratanakiri became one of benign neglect. The Khmer Loeu were permitted to return to their traditional livelihoods, but the government provided little infrastructure in the province.  Under the Vietnamese, there was little contact between the provincial government and many local communities. Long after the fall of the Khmer Rouge regime, however, Khmer Rouge rebels remained in the forests of Ratanakiri. Rebels largely surrendered their arms in the 1990s, though attacks along provincial roads continued until 2002.Ratanakiri's recent history has been characterized by development and attendant challenges to traditional ways of life. The national government has built roads, encouraged tourism and agriculture, and facilitated rapid immigration of lowland Khmers into Ratanakiri. Road improvements and political stability have increased land prices, and land alienation in Ratanakiri has been a major problem. Despite a 2001 law allowing indigenous communities to obtain collective title to traditional lands, some villages have been left nearly landless. The national government has granted concessions over land traditionally possessed by Ratanakiri's indigenous peoples, and even land "sales" have often involved bribes to officials, coercion, threats, or misinformation. Following the involvement of several international non-governmental organizations (NGOs), land alienation had decreased in frequency as of 2006. In the 2000s, Ratanakiri also received hundreds of Degar (Montagnard) refugees fleeing unrest in neighboring Vietnam; the Cambodian government was criticized for its forcible repatriation of many refugees.


Output: What practices of the Khmer Loeu were seen to be incompatible with communism?
