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: Despite undergoing various changes of emphasis, Bush's music retained a voice distinct from that of any of his contemporaries. One critic describes the typical Bush sound as "Mild dominant discords, of consonant effect, used with great originality in uncommon progressions alive with swift, purposeful harmonic movement ... except in [Benjamin] Britten they are nowhere used with more telling expression, colour and sense of movement than in Bush".John Ireland, Bush's early mentor, instilled "the sophisticated and restrained craftsmanship which marked Bush's music from the beginning", introducing him to folksong and Palestrina, both important building blocks in the development of Bush's mature style. Daula comments that "Bush's music does not [merely] imitate the sound-world of his Renaissance predecessors", but creates his unique fingerprint by "[juxtaposing] 16th century modal counterpoint with late- and post-romantic harmony".Bush's music, at least from the mid-1930s, often carried political overtones. His obituarist Rupert Christiansen writes that, as a principled Marxist, Bush "put the requirements of the revolutionary proletariat at the head of the composer's responsibilities", a choice which others, such as Tippett, chose not to make. However, Vaughan Williams thought that, despite Bush's oft-declared theories of the purposes of art and music, "when the inspiration comes over him he forgets all about this and remembers only the one eternal rule for all artists, 'To thine own self be true'.".

Output: What is the last name of the person who wrote that the composer who retained a voice distinct from that of any of his contemporaries "remembers only the one eternal rule for all artists, 'To thine own self be true'."?

Input: Consider Input: Passage: "Touch Me I'm Sick" was released on August 1, 1988, as a 7" vinyl. It was Mudhoney's debut release. Initially, Sub Pop released 800 clear coffee-brown vinyl copies, 200 black vinyl copies and a few assorted vinyl color copies of the single. The limited release numbers were inspired by another indie label, Amphetamine Reptile. Sub Pop owners Bruce Pavitt and Jonathan Poneman reasoned the limited supply would increase demand, and utilized different colors of vinyl in order to rationalize further limited pressings and to increase the single's allure as a collectible item. The record, which came in a white paper bag without a picture sleeve, had an inscription on the A-side: "What does the word 'crack' mean to you?". The B-side sticker featured the toilet picture that later became the cover art of the sleeved second edition of the single.According to Pavitt, "It was just a limited edition, maybe 800 pieces, but people all over America started raving about it. People that we really respected."
The single was an indie hit in Seattle, and "Touch Me I'm Sick" became Mudhoney's most recognizable song. When asked in an interview about the sales figures of the single, Turner replied, "The first [pressing sold] 1,000, then 3,000 of the reissue, then it was out of print for a while; then they made 2,000 more and those are probably gone." The single's success caught the band by surprise; Arm had initially dismissed the song as a "B-side toss off". "Touch Me I'm Sick" and B-side "Sweet Young Thing Ain't Sweet No More" were later included on the Mudhoney compilation albums Superfuzz Bigmuff Plus Early Singles (1990) and March to Fuzz (2000).

Output: What are the names of the compilation albums that include the song released on August 1, 1988?

Input: Consider Input: Passage: Petrus Christus placed his sitter in a naturalistic setting rather than a flat and featureless background. This approach was in part a reaction against van der Weyden, who, in his emphasis on sculptural figures, utilised very shallow pictorial spaces. In his 1462 Portrait of a Man, Dieric Bouts went further by situating the man in a room complete with a window that looks out at a landscape, while in the 16th century, the full-length portrait became popular in the north. The latter format was practically unseen in earlier northern art, although it had a tradition in Italy going back centuries, most usually in fresco and illuminated manuscripts. Full-length portraits were reserved for depictions of the highest echelon of society, and were associated with princely displays of power. Of the second generation of northern painters, Hans Memling became the leading portraitist, taking commissions from as far as Italy. He was highly influential on later painters and is credited with inspiring Leonardo's positioning of the Mona Lisa in front of a landscape view. Van Eyck and van der Weyden similarly influenced the French artist Jean Fouquet and the Germans Hans Pleydenwurff and Martin Schongauer among others.The Netherlandish artists moved away from the profile view popularised during the Italian Quattrocento towards the less formal but more engaging three-quarter view. At this angle, more than one side of the face is visible as the sitter's body is rotated towards the viewer. This pose gives a better view of the shape and features of the head and allows the sitter to look out towards the viewer. The gaze of the sitter rarely engages the viewer. Van Eyck's 1433 Portrait of a Man is an early example, which shows the artist himself looking at the viewer. Although there is often direct eye contact between subject and viewer, the look is normally detached, aloof and uncommunicative, perhaps to reflect the subject's high social position. There are exceptions, typically in bridal portraits or in the case of potential betrothals, when the object of the work is to make the sitter as attractive as possible. In these cases the sitter was often shown smiling, with an engaging and radiant expression designed to appeal to her intended.Around 1508, Albrecht Durer described the function of portraiture as "preserving a person's appearance after his death". Portraits were objects of status, and served to ensure that the individual's personal success was recorded and would endure beyond his lifetime. Most portraits tended to show royalty, the upper nobility or princes of the church. The new affluence in the Burgundian Netherlands brought a wider variety of clientele, as members of the upper middle class could now afford to commission a portrait. As a result, more is known about the appearance and dress of the region's people than at any time since the late Roman period. Portraits did not generally require lengthy sittings; typically a series of preparatory drawings were used to flesh out the final panel. Very few of these drawings survive, a notable exception being van Eyck's study for his Portrait of Cardinal Niccolo Albergati.
Output: What is the first name of the person who was highly influential on later painters?
