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.

Let me give you an 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.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: 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.

Passage: During his stay in Puerto Rico, Thompson acquired a fairly fluent, although informal and at times incorrect, use of Spanish, which he has continued throughout his career. Several early Pixies songs, including "Isla de Encanta" and "Vamos", reference his experiences in San Juan, and the lyrics are often heavily seasoned with the island's slang. The island's influence in his work is most notable in the song "Isla De Encanta", named after the island's motto, "Isla Del Encanto". Other Pixies songs drawn from his experiences there include "Vamos" (Come On Pilgrim), "Oh My Golly!", "Where Is My Mind?" (Surfer Rosa), "Crackity Jones" (Doolittle) and the B-side "Bailey's Walk". Several of his songs contain Spanish lyrics, most notably in the Pixies' first album, Come On Pilgrim, and a Spanish translation of "Evil Hearted You" by The Yardbirds. From his later works with the Pixies onwards, his use of Spanish drifted westward, reflecting places and aspects of the state of California and its culture.Thompson's lyrics are noted for their obscure references to off-beat topics such as outer space, UFOs, and The Three Stooges—the last of these being the subject of "Two Reelers", a song from Teenager of the Year. Lyrics with a focus on science fiction were particularly prominent on the later Pixies records, as well as his early solo albums. With the Catholics, his lyrics have tended towards historical topics; for example, the song "St. Francis Dam Disaster" (from Dog in the Sand) details the catastrophic collapse of the St. Francis Dam near Los Angeles in March 1928, and the All My Ghosts EP featured an account of the Humboldt County Massacre of Wiyot Indians in 1860 near Eureka, California.
Answer:
What is the name of the island whose influence in his work is most notable in the song "Isla De Encanta"?
