Task: Question Answering
Input (English): 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. 
Question: What is the name of the island whose motto is, "Isla Del Encanto," after which the Pixies song is named?
Output (English): Puerto Rico.
