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.

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.

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

Passage: The book is partly autobiographical. It follows the adventures of a group of people the narrator Laurie, the eccentric Dorothea ffoulkes-Corbett (otherwise Aunt Dot), her High Anglican clergyman friend Father Hugh Chantry-Pigg (who keeps his collection of sacred relics in his pockets) travelling from Istanbul (or Constantinople as Fr. Chantry-Pigg would have it) to Trebizond. A Turkish feminist doctor attracted to Anglicanism acts as a foil to the main characters.
On the way, they meet magicians, Turkish policemen and juvenile British travel-writers, and observe the BBC and Billy Graham on tour. Aunt Dot proposes to emancipate the women of Turkey by converting them to Anglicanism and popularising the bathing hat, while Laurie has more worldly preoccupations. Historical references (British Christianity since the Dissolution of the Monasteries, nineteenth-century travellers to the Ottoman Empire, the First World War, the Fourth Crusade, St. Paul's third missionary journey, Troy) abound.
The geographical canvas is enlarged with the two senior characters eloping to the Soviet Union and the heroine meeting her lover in Turkey, and then her semi-estranged mother in Jerusalem. The final chapters raise multiple issues such as the souls of animals, and culminate in a fatal accident and its aftermath.
At another level the book, against its Anglo-Catholic backdrop, deals with the conflict between Laurie's attraction to Christianity and her adulterous love for a married man. This was a problem Macaulay had faced in her own life, having had an affair with the married novelist and former Roman Catholic priest Gerald O'Donovan (18711942) from 1920 until his death.
The book's opening sentence is,"Take my camel, dear", said my Aunt Dot, as she climbed down from this animal on her return from High Mass.

Ex Output:
What is the thing that Laurie narrates?
