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: In August 1953, Presley checked into the offices of Sun Records. He aimed to pay for a few minutes of studio time to record a two-sided acetate disc: "My Happiness" and "That's When Your Heartaches Begin". He later claimed that he intended the record as a gift for his mother, or that he was merely interested in what he "sounded like", although there was a much cheaper, amateur record-making service at a nearby general store. Biographer Peter Guralnick argued that he chose Sun in the hope of being discovered. Asked by receptionist Marion Keisker what kind of singer he was, Presley responded, "I sing all kinds." When she pressed him on who he sounded like, he repeatedly answered, "I don't sound like nobody." After he recorded, Sun boss Sam Phillips asked Keisker to note down the young man's name, which she did along with her own commentary: "Good ballad singer. Hold."In January 1954, Presley cut a second acetate at Sun Records—"I'll Never Stand in Your Way" and "It Wouldn't Be the Same Without You"—but again nothing came of it. Not long after, he failed an audition for a local vocal quartet, the Songfellows. He explained to his father, "They told me I couldn't sing." Songfellow Jim Hamill later claimed that he was turned down because he did not demonstrate an ear for harmony at the time. In April, Presley began working for the Crown Electric company as a truck driver. His friend Ronnie Smith, after playing a few local gigs with him, suggested he contact Eddie Bond, leader of Smith's professional band, which had an opening for a vocalist. Bond rejected him after a tryout, advising Presley to stick to truck driving "because you're never going to make it as a singer".Phillips, meanwhile, was always on the lookout for someone who could bring to a broader audience the sound of the black musicians on whom Sun focused. As Keisker reported, "Over and over I remember Sam saying, 'If I could find a white man who had the Negro sound and the Negro feel, I could make a billion dollars.'" In June, he acquired a demo recording by Jimmy Sweeney of a ballad, "Without You", that he thought might suit the teenage singer. Presley came by the studio, but was unable to do it justice. Despite this, Phillips asked Presley to sing as many numbers as he knew. He was sufficiently affected by what he heard to invite two local musicians, guitarist Winfield "Scotty" Moore and upright bass player Bill Black, to work something up with Presley for a recording session.
Solution:
What is the last name of the artist that the receptionist marked as a "Good ballad singer."?
