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: During the filming of a TV commercial for a "Meat For Go" campaign set in London's Smithfield Market, stuntman Steve, disillusioned by the inanity of his job, absconds in an E-type Jaguar (one of the props) with a young actress/model, Dinah. After a visit to Oasis Swimming Pools, an open-air swimming-pool in central London, and a memorable scene in and around the Great Conservatory in the grounds of Syon House, they make their way across a wintry southern England towards Burgh Island, off the coast of Devon, which Dinah is contemplating buying, presumably to escape the pressures of her celebrity as the "Butcher Girl" on the back of the TV meat advertising campaign. This act of rebellion is cynically exploited by the advertising executive behind the campaign, Leon Zissell, who deputes two of his henchmen to pursue the fleeing couple.
On their journey, Steve and Dinah encounter first a group of proto-hippies, squatting in MOD-owned buildings on Salisbury Plain (some of this sequence was shot in the evacuated village of Imber) and then an unhappily married middle-aged couple (Yootha Joyce and Robin Bailey) in the opulent surroundings of the Royal Crescent in Bath, Somerset. Steve also plans to visit his boyhood hero, Louie, whose youth club in London's East End he attended, and who has since relocated to Devon.
Having fled the police, and Leon Zissell's henchmen, after a fancy-dress party in the Roman Baths at Bath, Steve and Dinah (with the rest of Steve's gang - and the police - in hot pursuit) make their way towards Devon. Steve's encounter with Louie is disappointing. Louie recognises Dinah instantly, because of her TV celebrity, but fails to recognise Steve and misremembers his name, even after being introduced. Dinah's island also proves to be disappointing. At low tide, it is reachable from the mainland, and Zissell, who is clearly besotted with Dinah, has already arrived.
answer:
What are the names of the couple who make their way across England towards Burgh Island?


question:
Passage: All rock now exposed in the area of the park is volcanic, but this has not always been the case. For hundreds of millions of years, the Lassen region underwent repeated uplifting to form mountains, only to have them worn down and submerged under encroaching seas. During the periods of submersion, sand, mud and limestone were deposited. Occasionally volcanic activity was associated with the mountain building.
About 70 million years ago, the area where the Cascade Range is now situated was under the most recent encroachment by the Pacific Ocean. The rocks that make up the modern Sierra Nevada and the Klamath Mountains were already in existence but deeply buried. Some 70 million years before (140 million years before present), the rocks that now make up the Klamaths broke away from the rocks that now make up the Sierras and moved 60 mi (97 km) west, leaving the flooded 'Lassen Strait.' This broad depression was a seaway that connected the marine basin in California with that in east central Oregon.The entire western portion of North America was being deformed from the Laramide orogeny starting around 70 million years ago. Gradually during millions of years, crustal rocks were folded and fractured and the seas driven away. This same bending and breaking of rocks relieved pressure on the hot material beneath the Earth's crust and permitted magma to rise toward the surface. Volcanoes burst into activity starting 30 million years ago from Washington southward along the Cascades and in the area now occupied by the Sierra Nevada. This activity continued until approximately 11 or 12 million years ago. Lava and ash reached a thickness of up to 10,000 ft (3,000 m) in some areas, forming what is now known as the western Cascades. These have been eroded until they are now rolling hills.
Meanwhile, toward the end of this activity, eruptions of a different kind took place on an unprecedented scale in eastern Oregon and Washington. From innumerable cracks, floods of highly fluid basaltic lava spread to cover an area of over 200,000 sq mi (520,000 km2). Now known as the Columbia Plateau, this great lava bed of flood basalt covers much of Oregon, Washington and even parts of Idaho. Northern California's Modoc Plateau is a thinner basaltic flow which some geologists associate with the Columbia Plateau, but there are technical objections to this. The High Cascades took shape as a distinct mountain belt as a result of this upheaval and the bending of the thick blanket of volcanic rocks. During the next 10 million years, a series of new basaltic volcanic cones similar to the shield volcanoes now found in Hawaii were built.
answer:
What is the modern name for the area that formed after floods of highly fluid basaltic lava spread to cover an area of over 200,000 sq mi?


question:
Passage: Altar 13 is another early Maya monument dating to the Late Preclassic. Like Altar 12 it was probably originally erected as a vertical stela. At some point it was deliberately broken, with severe damage inflicted upon the main portion of the sculpture, obliterating the central and lower portions. At a later date it was reused as a horizontal altar. The remains of two figures can be seen flanking the damage lower portion of the monument and the large head of the sacred bird survives above the area of damage. The right hand figure is wearing an interwoven skirt and is probably female.Altar 18 was one of five monuments forming a north-south row at the base of Structure 8 on Terrace 3.Altar 28 is located near Structure 10 in the Central Group. It is a circular basalt altar just over 2 metres (79 in) in diameter and 0.5 metres (20 in) thick. On the front rim of the altar is a carving of a skull. On the upper surface are two relief carvings of human feet.Altar 30 is embedded in the fourth step of the access stairway to Terrace 3 in the Central Group. It has four low legs supporting it and is similar to Altar 9.Altar 48 is a very early example of the Early Maya style of sculpture, dating to the first part of the Late Preclassic, between 400 and 200 BC. Altar 48 is fashioned from andesite and measures 1.43 by 1.26 metres (4.7 by 4.1 ft) and is 0.53 metres (1.7 ft) thick. It is located near the southern extreme of Terrace 3, where it is one of a row of 5 monuments running east-west. It is carved on its upper face and upon all four sides. The upper surface bears the intricate design of a crocodile with its body in the form of a symbol representing a cave and containing the figure of a seated Maya wearing a loincloth. The sides of the monument are carved with an early form of Maya hieroglyphs, the text appears to refer directly to the person depicted on the upper surface. Altar 48 had been carefully covered by Stela 14. The emergence of a Maya ruler from the body of the crocodile parallels the myth of the birth of the Maya maize god, who emerges from the shell of a turtle. As such, Altar 48 may be one of the earliest depictions of Maya mythology used for political ends.
answer:

What structure has two relief carvings of human feet?
