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: Altar 1 is found at the base of Stela 1. It is rectangular in shape with carved molding on its side.Altar 2 is of unknown provenance, having been moved to outside the administrator's house on the San Isidro Piedra Parada plantation. It is 1.59 metres (63 in) long, about 0.9 metres (35 in) wide and about 0.5 metres (20 in) high. It represents an animal variously identified as a toad and a jaguar. The body of the animal was sculptured to form a hollow 85 centimetres (33 in) across and 26 centimetres (10 in) deep. The sculpture was broken into three pieces.Altar 3 is a roughly worked flat, circular altar about 1 metre (39 in) across and 0.3 metres (12 in) high. It was probably associated originally with a stela but its original location is unknown, it was moved near to the manager's house on the San Isidro Piedra Parada plantation.Altar 5 is a damaged plain circular altar associated with Stela 2.Altar 7 is near the southern edge of the plaza on Terrace 3, where it is one of five monuments in a line running east-west.Altar 8 is a plain monument associated with Stela 5, positioned on the west side of Structure 12.Altar 9 is a low four-legged throne placed in front of Structure 11.Altar 10 was associated with Stela 13 and was found on top of the large offering of ceramics associated with that stela and the royal tomb in Structure 7A. The monument was originally a throne with cylindrical supports that was reused as an altar in the Classic period.Altar 12 is carved in the early Maya style and archaeologists consider it to be an especially early example dating to the first part of the Late Preclassic. Because of the carvings on the upper face of the altar, it is supposed that the monument was originally erected as a vertical stela in the Late Preclassic, and was reused as a horizontal altar in the Classic. At this time 16 hieroglyphs were carved around the outer rim of the altar. The carving on the upper face of the altar represents a standing human figure portrayed in profile, facing left. The figure is flanked by two vertical series of four glyphs. A smaller profile figure is depicted facing the first figure, separated from it by one of the series of glyphs. The central figure is depicted standing upon a horizontal band representing the earth, the band is flanked by two earth monsters. Above the figure is a celestial band with part of the head of a sacred bird visible in the centre. The 16 glyphs on the rim of the monument are formed by anthropomorphic figures mixed with other elements.

SOLUTION: What is the name of the sculpture that was broken into three pieces?

PROBLEM: Passage: Geophysicist Dr. Josh Keyes and scientists Dr. Serge Leveque and Dr. Conrad Zimsky become aware of an instability of Earth's magnetic field after a series of bizarre incidents across the globe. They determine that the Earth's molten core, which generates this field, has stopped rotating and that, within a year, the field will collapse, exposing the planet's surface directly to devastating solar radiation. Backed by the U.S. Government, Keyes, Leveque, and Zimsky create a plan to bore down to the core and set off several nuclear explosions to restart the rotation. They gain the help of rogue scientist Dr. Ed "Braz" Brazzelton, who has devised a vessel made of "Unobtainium" that can withstand the heat and pressure within the Earth's crust and convert it to energy, as well as a laser-driven boring system that will allow them to quickly pass through the crust.
Construction starts immediately on the Virgil, a multi-compartment vessel to be helmed by Space Shuttle Endeavour pilots Commander Robert Iverson and Major Rebecca "Beck" Childs, who will join Keyes and the others. To prevent a worldwide panic, Keyes enlists computer hacker Theodore Donald "Rat" Finch to scour the Internet and eliminate all traces of the pending disaster or their plan.

SOLUTION: What three people find out about the world's impending doom?

PROBLEM: Passage: The chief building material of the church is buff sandstone, which came from the Goodrich Quarry (also called the Greystone Quarry) in the Almaden area of San Jose, was delivered by train and rough-cut in the university Quad.  Gregg credits the high quality of the stonework to church and university builder John D. McGilvray.  The church is roofed with terracotta tiles of the Italian imbrex and tegula form. The nave, chancel, and transepts appear to project from the square central structure, roofed with tiles and a small skylight above its center.  Memorial Church originally had a central bell tower with an 80-foot tall, twelve-sided spire, but this was lost as a result of the 1906 earthquake.The church's facade is surmounted by a simple Celtic cross, a motif that appears several times throughout the building.  The cross was added after the 1906 earthquake; its central shaft was destroyed in the Loma Prieta earthquake and replaced.  There are three arched entrances below the exterior mosaic; the central one is slightly larger than the others.  The surrounding stonework is intricately carved with stylized flora, twisted-cable moldings, and bosses of sculpted cherubim, a motif which occurs in different media throughout the church. In the spandrels are mosaic depictions of the biblical concepts of love, faith, hope and charity intertwined in a vine representing the "tree of life".In the upper zone of the facade, surrounded by more elaborate stonework and "lacy carving", is a large central window, with groups of three smaller windows on each side.  The original central window was a quatrefoil-shaped rose window, but after the 1906 earthquake, it was replaced by a "classical round-head window that more grandly restates the smaller flanking, articulated openings" and that corresponded with the mission-style architecture of the Quad.  Beneath the windows are inlaid panels of colored marble.

SOLUTION:
What church's chief building material was buff sandstone?
