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: Despite a political climate that was unfavorable to modern art (often denounced as "formalist" by the communist authorities), post-war Polish composers enjoyed an unprecedented degree of compositional freedom following the establishment of the Warsaw Autumn festival in 1956. Górecki had won recognition among avant-garde composers for the experimental, dissonant and serialist works of his early career; he became visible on the international scene through such modernist works as Scontri, which was a success at the 1960 Warsaw Autumn, and his First Symphony, which was awarded a prize at the 1961 Paris Youth Bienniale. Throughout the 1960s, he continued to form acquaintanceships with other experimental and serialist composers such as Pierre Boulez and Karlheinz Stockhausen.
During the 1970s, Górecki began to distance himself from the serialism and extreme dissonance of his earlier work, and his Third Symphony, like the preceding choral pieces Euntes ibant et flebant (Op. 32, 1972) and Amen (Op. 35, 1975), starkly rejects such techniques. The lack of harmonic variation in Górecki's Third Symphony, and its reliance on repetition, marked a stage in Górecki's progression towards the harmonic minimalism and the simplified textures of his more recent work. Because of the religious nature of many of his works during this period, critics and musicologists often align him with other modernist composers who began to explore radically simplified musical textures, tonality, and melody, and who also infused many of their works with religious significance. Like-minded composers, such as Arvo Pärt and John Tavener, are frequently grouped with Górecki under the term "holy minimalism," although none of the composers classified as such has admitted to common influences.
What is the last name of the person who continued to form acquaintanceships with other experimental and serialist composers ?

Passage: With an average flow at the mouth of about 37,400 cubic feet per second (1,060 m3/s), the Willamette ranks 19th in volume among rivers in the United States and contributes 12 to 15 percent of the total flow of the Columbia River. The Willamette's flow varies considerably season to season, averaging about 8,200 cubic feet per second (230 m3/s) in August to more than 79,000 cubic feet per second (2,200 m3/s) in December.
The U.S. Geological Survey (USGS) operates five stream gauges along the river, at Harrisburg, Corvallis, Albany, Salem, and Portland. The average discharge at the lowermost gauge, near the Morrison Bridge in Portland, was 33,220 cubic feet per second (941 m3/s) between 1972 and 2013. Located at river mile (RM) 12.8 or river kilometer (RK) 20.6, the gauge measures the flow from an area of 11,200 square miles (29,000 km2), roughly 97 percent of the Willamette basin. The highest flow recorded at this station was 420,000 cubic feet per second (11,893 m3/s) on February 9, 1996, during the Willamette Valley Flood of 1996, and the minimum was 4,200 cubic feet per second (120 m3/s) on July 10, 1978. The highest recorded flow of 635,000 cubic feet per second (18,000 m3/s) for the Willamette at a different gauge in Portland occurred during a flood in 1861. This and many other large flows preceded the Flood Control Act of 1936 and dam construction on the Willamette's major tributaries.The river below Willamette Falls, 26.5 miles (42.6 km) from the mouth, is affected by semidiurnal tides, and gauges have detected reverse flows (backwards river flows) upstream from Ross Island at RM 15 (RK 24). The National Weather Service issues tide forecasts for the river at the Morrison Bridge.
In what month is the flow of the WIllamette the lowest?

Passage: During his marriage to Cynthia, Lennon's first son Julian was born at the same time that his commitments with the Beatles were intensifying at the height of Beatlemania. Lennon was touring with the Beatles when Julian was born on 8 April 1963. Julian's birth, like his mother Cynthia's marriage to Lennon, was kept secret because Epstein was convinced that public knowledge of such things would threaten the Beatles' commercial success. Julian recalled that as a small child in Weybridge some four years later, "I was trundled home from school and came walking up with one of my watercolour paintings. It was just a bunch of stars and this blonde girl I knew at school. And Dad said, 'What's this?' I said, 'It's Lucy in the sky with diamonds.'" Lennon used it as the title of a Beatles song, and though it was later reported to have been derived from the initials LSD, Lennon insisted, "It's not an acid song." Lennon was distant from Julian, who felt closer to McCartney than to his father. During a car journey to visit Cynthia and Julian during Lennon's divorce, McCartney composed a song, "Hey Jules", to comfort him. It would evolve into the Beatles song "Hey Jude". Lennon later said, "That's his best song. It started off as a song about my son Julian  ... he turned it into 'Hey Jude'. I always thought it was about me and Yoko but he said it wasn't."Lennon's relationship with Julian was already strained, and after Lennon and Ono moved to New York in 1971, Julian did not see his father again until 1973. With Pang's encouragement, arrangements were made for Julian and his mother to visit Lennon in Los Angeles, where they went to Disneyland. Julian started to see his father regularly, and Lennon gave him a drumming part on a Walls and Bridges track. He bought Julian a Gibson Les Paul guitar and other instruments, and encouraged his interest in music by demonstrating guitar chord techniques. Julian recalls that he and his father "got on a great deal better" during the time he spent in New York: "We had a lot of fun, laughed a lot and had a great time in general."In a Playboy interview with David Sheff shortly before his death, Lennon said, "Sean was a planned child, and therein lies the difference. I don't love Julian any less as a child. He's still my son, whether he came from a bottle of whiskey or because they didn't have pills in those days. He's here, he belongs to me, and he always will." He said he was trying to reestablish a connection with the then 17-year-old, and confidently predicted, "Julian and I will have a relationship in the future." After his death it was revealed that he had left Julian very little in his will.

What is the last name of the person that encouraged Lennon's first son to see Lennon more?
