Detailed Instructions: 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: Japanese art since the Heian period (794–1185) had followed two principal paths: the nativist Yamato-e tradition, focusing on Japanese themes, best known by the works of the Tosa school; and Chinese-inspired kara-e in a variety of styles, such as the monochromatic ink wash painting of Sesshū Tōyō and his disciples.  The Kanō school of painting incorporated features of both.Since antiquity, Japanese art had found patrons in the aristocracy, military governments, and religious authorities.  Until the 16th century, the lives of the common people had not been a main subject of painting, and even when they were included, the works were luxury items made for the ruling samurai and rich merchant classes.  Later works appeared by and for townspeople, including inexpensive monochromatic paintings of female beauties and scenes of the theatre and pleasure districts.  The hand-produced nature of these shikomi-e limited the scale of their production, a limit that was soon overcome by genres that turned to mass-produced woodblock printing.
During a prolonged period of civil war in the 16th century, a class of politically powerful merchants had developed.  These machishū allied themselves with the court and had power over local communities; their patronage of the arts encouraged a revival in the classical arts in the late 16th and early 17th centuries.  In the early 17th century Tokugawa Ieyasu (1543–1616) unified the country and was appointed shōgun with supreme power over Japan.  He consolidated his government in the village of Edo (modern Tokyo), and required the territorial lords to assemble there in alternate years with their entourages.  The demands of the growing capital drew many male labourers from the country, so that males came to make up nearly seventy percent of the population.  The village grew during the Edo period (1603–1867) from a population of 1800 to over a million in the 19th century.The centralized shogunate put an end to the power of the machishū and divided the population into four social classes, with the ruling samurai class at the top and the merchant class at the bottom.  While deprived of their political influence, those of the merchant class most benefited from the rapidly expanding economy of the Edo period, and their improved lot allowed for leisure that many sought in the pleasure districts—in particular Yoshiwara in Edo—and collecting artworks to decorate their homes, which in earlier times had been well beyond their financial means.  The experience of the pleasure quarters was open to those of sufficient wealth, manners, and education.
