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: 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.

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


Input: Consider Input: Passage: Young Max Skinner, whose parents have died in an accident, spends his childhood summer holidays learning to appreciate the finer things in life at his Uncle Henry's vineyard estate in Provence in southeastern France. Some 25 years later, Max is an unethical, successful, and hard-working London-based bond trader with a sense of humour.
Following his uncle's death, Max is the sole beneficiary of the French property. He travels to Provence to prepare a quick sale. Shortly after arriving, by driving while fumbling with a cell phone, he unknowingly causes a local café owner, Fanny Chenal, to crash her bicycle. Subsequently, he discovers that his latest City financial stunt has caused real trouble for the owners of the trading company he works for, and the CEO orders him to return to London as soon as possible.
To assist in his planned sale of the property, Max hurriedly snaps some photos and in the process falls into an empty swimming pool. He is unable to escape until Fanny, driving by and spotting his rental car, turns on the water supply in retaliation. This delay causes Max to miss his flight and, having failed to report to the directors in person, he is suspended from work and trading activities for one week.
On Henry's estate, Max must deal with a gruff, dedicated winemaker, Francis Duflot, who fears being separated from his precious vines. Duflot pays a vineyard inspector to tell Max that the soil is bad and the vines worthless.

Output: What is the full name of the person that turned on the water in retaliation?


Input: Consider Input: Passage: There are two major valleys in the park, Death Valley and Panamint Valley. Both of these valleys were formed within the last few million years and both are bounded by north–south-trending mountain ranges. These and adjacent valleys follow the general trend of Basin and Range topography with one modification: there are parallel strike-slip faults that perpendicularly bound the central extent of Death Valley. The result of this shearing action is additional extension in the central part of Death Valley which causes a slight widening and more subsidence there.
Uplift of surrounding mountain ranges and subsidence of the valley floor are both occurring. The uplift on the Black Mountains is so fast that the alluvial fans (fan-shaped deposits at the mouth of canyons) there are small and steep compared to the huge alluvial fans coming off the Panamint Range. Fast uplift of a mountain range in an arid environment often does not allow its canyons enough time to cut a classic V-shape all the way down to the stream bed. Instead, a V-shape ends at a slot canyon halfway down, forming a 'wine glass canyon.'  Sediment is deposited on a small and steep alluvial fan.
At 282 feet (86 m) below sea level at its lowest point, Badwater Basin on Death Valley's floor is the second-lowest depression in the Western Hemisphere (behind Laguna del Carbón in Argentina), while Mount Whitney, only 85 miles (137 km) to the west, rises to 14,505 feet (4,421 m). This topographic relief is the greatest elevation gradient in the contiguous United States and is the terminus point of the Great Basin's southwestern drainage. Although the extreme lack of water in the Great Basin makes this distinction of little current practical use, it does mean that in wetter times the lake that once filled Death Valley (Lake Manly) was the last stop for water flowing in the region, meaning the water there was saturated in dissolved materials. Thus the salt pans in Death Valley are among the largest in the world and are rich in minerals, such as borax and various salts and hydrates. The largest salt pan in the park extends 40 miles (64 km) from the Ashford Mill Site to the Salt Creek Hills, covering some 200 square miles (520 km2) of the valley floor. The best known playa in the park is the Racetrack, known for its moving rocks.


Output: What is the lowest point of Death Valley?
