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


question:
Passage: Following the purchase of two of his paintings by the Prussian Crown Prince, Friedrich was elected a member of the Berlin Academy in 1810. Yet in 1816, he sought to distance himself from Prussian authority and applied that June for Saxon citizenship. The move was not expected; the Saxon government was pro-French, while Friedrich's paintings were seen as generally patriotic and distinctly anti-French. Nevertheless, with the aid of his Dresden-based friend Graf Vitzthum von Eckstädt, Friedrich attained  citizenship, and in 1818, membership in the Saxon Academy with a yearly dividend of 150 thalers. Although he had hoped to receive a full professorship, it was never awarded him as, according to the German Library of Information, "it was felt that his painting was too personal, his point of view too individual to serve as a fruitful example to students." Politics too may have played a role in  stalling his career: Friedrich's decidedly Germanic subjects and costuming frequently clashed with the era's prevailing pro-French attitudes.
answer:
What is the first name of the man that the Dresden-based person helped attain membership into the Saxon Academy?


question:
Passage: Macedonia ( (listen); Greek: Μακεδονία, Makedonía), also called Macedon (), was an ancient kingdom on the periphery of Archaic and Classical Greece, and later the dominant state of Hellenistic Greece. The kingdom was founded and initially ruled by the royal Argead dynasty, which was followed by the Antipatrid and Antigonid dynasties. Home to the ancient Macedonians, the earliest kingdom was centered on the northeastern part of the Greek peninsula, and bordered by Epirus to the west, Paeonia to the north, Thrace to the east and Thessaly to the south.
Before the 4th century BC, Macedonia was a small kingdom outside of the area dominated by the great city-states of Athens, Sparta and Thebes, and briefly subordinate to Achaemenid Persia. During the reign of the Argead king Philip II (359–336 BC), Macedonia subdued mainland Greece and Thrace through conquest and diplomacy. With a reformed army containing phalanxes wielding the sarissa pike, Philip II defeated the old powers of Athens and Thebes in the Battle of Chaeronea in 338 BC. Philip II's son Alexander the Great, leading a federation of Greek states, accomplished his father's objective of commanding the whole of Greece when he destroyed Thebes after the city revolted. During Alexander's subsequent campaign of conquest, he overthrew the Achaemenid Empire and conquered territory that stretched as far as the Indus River. For a brief period, his empire was the most powerful in the world – the definitive Hellenistic state, inaugurating the transition to a new period of Ancient Greek civilization. Greek arts and literature flourished in the new conquered lands and advances in philosophy, engineering, and science spread throughout much of the ancient world. Of particular importance were the contributions of Aristotle, tutor to Alexander, whose writings became a keystone of Western philosophy.
After Alexander's death in 323 BC, the ensuing wars of the Diadochi, and the partitioning of Alexander's short-lived empire, Macedonia remained a Greek cultural and political center in the Mediterranean region along with Ptolemaic Egypt, the Seleucid Empire, and the Kingdom of Pergamon. Important cities such as Pella, Pydna, and Amphipolis were involved in power struggles for control of the territory. New cities were founded, such as Thessalonica by the usurper Cassander (named after his wife Thessalonike of Macedon). Macedonia's decline began with the Macedonian Wars and the rise of Rome as the leading Mediterranean power. At the end of the Third Macedonian War in 168 BC, the Macedonian monarchy was abolished and replaced by Roman client states. A short-lived revival of the monarchy during the Fourth Macedonian War in 150–148 BC ended with the establishment of the Roman province of Macedonia.
answer:

What is the full name of the person that had the most powerful empire in the world?
