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: A poacher hides from an unknown creature in his boat. While it breaks through the boat and attempts to catch the poacher, he commits suicide by shooting himself dead to prevent the beast from killing him.
Meanwhile while shooting a documentary about a long-lost indigenous tribe, the Shirishamas, on the Amazon River, director Terri Flores and members of her crew including cameraman Danny Rich, production manager Denise Kalberg, her boyfriend, sound engineer Gary Dixon, visionary Warren Westridge, anthropologist Professor Steven Cale, and boat skipper Mateo come across stranded Paraguayan snake hunter Paul Serone and help him, believing he knows how to find the tribe they are searching for.
Most of the crew are uncomfortable around Serone, and Cale clashes with him several times in regards to Shirishama lore. Later, while trying to free the boat's propeller from a rope, Cale is stung in the throat by a wasp inside his scuba regulator, which swells his throat shut and leaves him unconscious. Serone performs an emergency cricothyrotomy, seemingly saving Cale's life. With that, Serone takes command and captain of the boat and the crew. They are then forced to help him achieve his true task: hunting down and capturing a giant record-breaking female green anaconda he had been tracking the whole time.
Later, Mateo gets lost and is the first to be killed by the anaconda, which coils around him before it snaps his neck near the boat where the poacher had been killed. A photograph in an old newspaper reveals that Mateo, Serone, and the unnamed poacher were actually working together to catch animals, including snakes. The others try to find him while Gary sides with Serone, who promises if they help him find the anaconda, he will help them get out alive.
answer:
Gary Dixon is a member of whose crew?

Passage: Big Enos and Little Enos offer retiring Sheriff Buford T. Justice a wager, betting $250,000 against his badge on his ability to transport a large stuffed fish from Florida to Texas. Buford picks up the fish and starts driving with his son, Junior.
The Enoses set many traps, but Buford dodges them, so they try to hire the Bandit to stop him. Deciding that the original Bandit is too hard to manage, they hire the Snowman to act as the Bandit. The new Snowman/Bandit parks his truck so he can drive a black and gold 1983 Pontiac Trans Am.
The Bandit picks up Dusty, who quits her job at a used car dealership. The Bandit catches up with Buford and steals the fish. Buford pursues the Bandit, with another local officer who attempts to take charge of the situation. Both police cars are disabled in the chase.
Buford catches up after the Bandit and Dusty stop at a redneck bar to eat. The chase then creates mass chaos in a local town. The Bandit escapes when an 18-wheeler blocks the alleyway where the Bandit ran through on foot. While trying to get the truck out, Buford's car is towed, but he reverses the car and escapes. The tow truck operator chases him, with Junior spinning on the hook. Buford makes the truck flip over, sending Junior flying. Other cars crash into the pile-up. 
Buford chases the Bandit in the Mississippi Fairgrounds. Buford's car is thrown up on two side wheels by an incline, but he continues the pursuit while driving on two wheels.
At night, the Bandit and Dusty stop at a hotel, where people are involved in sexual acts, some deviant. Buford sees the Bandit's Trans-Am parked there, and searches for the fish, which he finds. Buford thinks he found the Bandit in the sauna, but it turns out to be a muscular woman who bonds with him.
answer:
What is the last name of the person that the Enoses hire the Bandit to stop?


question:
Passage: In 17th-century Spain, painters rarely enjoyed high social status. Painting was regarded as a craft, not an art such as poetry or music. Nonetheless, Velázquez worked his way up through the ranks of the court of Philip IV, and in February 1651 was appointed palace chamberlain (aposentador mayor del palacio). The post brought him status and material reward, but its duties made heavy demands on his time. During the remaining eight years of his life, he painted only a few works, mostly portraits of the royal family. When he painted Las Meninas, he had been with the royal household for 33 years.
Philip IV's first wife, Elizabeth of France, died in 1644; and their only son, Balthasar Charles, died two years later. Lacking an heir, Philip married Mariana of Austria in 1649, and Margaret Theresa (1651–1673) was their first child, and their only one at the time of the painting. Subsequently, she had a short-lived brother Philip Prospero (1657–1661), and then Charles (1661–1700) arrived, who succeeded to the throne as Charles II at the age of three. Velázquez painted portraits of Mariana and her children, and although Philip himself resisted being portrayed in his old age he did allow Velázquez to include him in Las Meninas. In the early 1650s he gave Velázquez the Pieza Principal ("main room") of the late Balthasar Charles's living quarters, by then serving as the palace museum, to use as his studio. It is here that Las Meninas is set. Philip had his own chair in the studio and would often sit and watch Velázquez at work. Although constrained by rigid etiquette, the art-loving king seems to have had a close relationship with the painter. After Velázquez's death, Philip wrote "I am crushed" in the margin of a memorandum on the choice of his successor.During the 1640s and 1650s, Velázquez served as both court painter and curator of Philip IV's expanding collection of European art. He seems to have been given an unusual degree of freedom in the role. He supervised the decoration and interior design of the rooms holding the most valued paintings, adding mirrors, statues and tapestries. He was also responsible for the sourcing, attribution, hanging and inventory of many of the Spanish king's paintings. By the early 1650s, Velázquez was widely respected in Spain as a connoisseur. Much of the collection of the Prado today—including works by Titian, Raphael, and Rubens—were acquired and assembled under Velázquez's curatorship.
answer:

What is the name of Philip IV's final child?
