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.
One example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Solution is here: Who believes Fagin's gang make wallets and handkerchiefs?.
Explanation: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Now, solve this: Passage: Young's drum performance on Slay Tracks eventually led to him joining Pavement as a full-time member. Young produced the group's 1990 EP Demolition Plot J-7, but displayed hostility toward then-current drummer Jason Fawkes. Fawkes left Pavement in 1991 due to animosity with Malkmus, allowing Young to drum on their third EP, Perfect Sound Forever. Young drummed on all Pavement releases from then on until 1992's Watery, Domestic, after which he was fired for his increasingly erratic behavior and was replaced with Steve West. Young's drumming on Slay Tracks was later recognized as an important turning point in Pavement's history, and was considered to be "the opportunity of a lifetime" by C. Harris-Nystrom of the News & Review.Dan Koretzky, founder of Drag City, ordered 200 copies of the EP for the Chicago Reckless Records store he worked for at the time. Koretzky asked Kannberg if he would sign to Drag City during the same phone call that he ordered the EP. Kannberg remembered expressing reluctance to sign to any label, but Drag City producer and session musician Rian Murphy recalled that "We asked, they said yes. Lives didn't seem to be on the line." Chris Lombardi and Gerard Cosloy of Matador Records also first heard of Pavement after Kannberg sent a copy of Slay Tracks to their zine, Conflict. Matador signed Pavement in 1992 for the release of their debut studio album, Slanted and Enchanted.
The songs on Slay Tracks are all included on the 1993 compilation Westing (By Musket and Sextant), along with several of Pavement's other early material. Westing has sold 63,000 copies, and was praised by Robert Christgau and Stephen Thomas Erlewine for making songs previously found exclusively on vinyl available on compact disc. All of the songs from Slay Tracks were played live throughout Pavement's history, with "Box Elder" particularly cited as an "old favorite" for fans at concerts. Live performances of "Box Elder" has also been included on the compilation reissues Slanted and Enchanted: Luxe & Reduxe and Wowee Zowee: Sordid Sentinels Edition, with the version on the latter beginning with a short jam session. In a 1999 retrospective of the band's career, Donna Freydkin of CNN.com called  Slay Tracks "a quick underground favorite", while John Hicks of the Planet Weekly wrote "Although Pavement was conceived as a studio-only project, the underground success of Slay Tracks ensured that it was only a matter of time before the group became a full-fledged performing entity.".
Solution:
What are the last names of the two people in Pavement who had animosity between them?
