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.

[Q]: Passage: Holland is a former CIA assassin who lives quietly and peacefully on the Cayman Islands. He is persuaded out of retirement by the death of Jorge Hidalgo, a friend and dissident journalist. Hidalgo was murdered by Clement Molloch, a Welsh doctor who lives in Guatemala. Molloch is an expert in the science of torture and sells his knowledge and skills to any government that can pay his price. He lives under government protection in Guatemala.
Holland is hired by Hector Lomelin, a professor and friend of Hidalgo. He poses as a family man and is accompanied to Guatemala by Hidalgo's widow Rhiana and daughter Sarah.
Holland kills several of Molloch's men, and then kidnaps his sister Claire, allegedly for ransom. She is killed during a chase by thugs hired by the US ambassador, who has used Molloch for his own purposes in the past. Molloch, believing his sister is still alive, meets Holland at a remote location to pay the ransom. He's kidnapped Hidalgo's daughter Sarah and holds her in exchange for his sister. Local miners know that Molloch has tortured their family members and attack him with pick and shovel. Sarah, her mother Rhiana, and Holland leave his death in the hands of the local people.

[Q]: 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.
[A]: What was the first name of the person who was able to rally support and the coup collapsed the next morning without any casualties?


[Q]: Passage: Using an unofficial nickname of "The River City", Jacksonville has a culture centered on the St. Johns. An annual footrace named the Gate River Run accepts 18,000 participants who travel a course along and over the river twice. The largest kingfishing tournament in the U.S. is held on a St. Johns tributary, where sport fishers concentrate on king mackerel (Scomberomorus cavalla), cobia (Rachycentron canadum), dolphin (Coryphaena hippurus) and Wahoo (Acanthocybium solandri). The home stadium for the Jacksonville Jaguars faces the river, as does most of the commercial center of downtown. Seven bridges span the St. Johns at Jacksonville; all of them allow tall ships to pass, although some restrict passing times when train or automobile traffic is heavy.Tides cause seawater to enter the mouth of the St. Johns River and can affect the river's level into the middle basin. As a result, much of the river in Jacksonville is part seawater, making it an estuarine ecosystem. The animals and plants in these systems can tolerate both fresh and salt water, and the fluctuations in saline content and temperatures associated with tidal surges and heavy rainfall discharge. Marine animals such as dolphins and sharks can be spotted at times in the St. Johns at Jacksonville as can manatees. Fish such as mullet (Mullidae), flounder (Paralichthys lethostigma), shad (Alosa sapidissima), and blue crabs (Callinectes sapidus) migrate from the ocean to freshwater springs upriver to spawn.Although freshwater invertebrates inhabiting and comprising algae and periphyton make the foundation of food webs in the middle and lower basin, zooplankton and phytoplankton take that role in the estuarine habitat. Mollusks gather at the St. Johns estuary in large numbers, feeding on the bottom of the river and ocean floors. The abundance and importance of oysters (Crassostrea virginica) is apparent in the many middens left by the Timucua in mounds many feet high. Oysters and other mollusks serve as the primary food source of shorebirds. The large trees that line the river from its source to south of Jacksonville begin to transition into salt marshes east of the city. Mayport is home to approximately 20 shrimping vessels that use the mouth of the St. Johns to access the Atlantic Ocean.
[A]:
What are the type of mollusk that is left in mounds many feet high?
