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: When Harrison joined the Quarrymen in 1958 his main guitar was a Höfner President Acoustic, which he soon traded for a Höfner Club 40 model. His first solid-body electric guitar was a Czech-built Jolana Futurama/Grazioso. The guitars he used on early recordings were mainly Gretsch models, played through a Vox amplifier, including a Gretsch Duo Jet that he bought secondhand in 1961, and posed with on the album cover for Cloud Nine. He also bought a Gretsch Tennessean and a Gretsch Country Gentleman, which he played on "She Loves You", and during the Beatles' 1964 appearance on The Ed Sullivan Show. In 1963 he bought a Rickenbacker 425 Fireglo, and in 1964 he acquired a Rickenbacker 360/12 guitar, which was the second of its kind to be manufactured. Harrison obtained his first Fender Stratocaster in 1965 and first used it during the recording of the Help! album that February; he also used it when recording Rubber Soul later that year, most notably on the song "Nowhere Man".In early 1966 Harrison and Lennon each purchased Epiphone Casinos, which they used on Revolver. Harrison also used a Gibson J-160E and a Gibson SG Standard while recording the album. He later painted his Stratocaster in a psychedelic design that included the word "Bebopalula" above the pickguard and the guitar's nickname, "Rocky", on the headstock. He played this guitar in the Magical Mystery Tour film and throughout his solo career. In July 1968, Clapton gave him a Gibson Les Paul, which Harrison nicknamed "Lucy". Around this time, he obtained a Gibson Jumbo J-200 acoustic guitar, which he subsequently gave to Dylan to use at the 1969 Isle of Wight Festival. In late 1968 Fender Musical Instruments Corporation gave Harrison a custom-made Fender Telecaster Rosewood prototype, made especially for him by Philip Kubicki. In August 2017, Fender released a "Limited Edition George Harrison Rosewood Telecaster" modelled after a Telecaster that Roger Rossmeisl originally created for Harrison.
Solution:
What is the last name of the man who gave a Gibson Les Paul to the musician who nicknamed a guitar "Rocky"?
