Q: Question: Which of the two characters that were additional features to Superman was introduced first? Passage 1:Fago was born in 1914 in Yonkers, New York, of parents who had immigrated from Naples, Italy. He had two sisters and a 10-year-older brother, Al Fago. At 14, Vincent Fago sold his first cartoon to the New York Sun, for $2. He attended DeWitt Clinton High School in the Bronx, graduating at age 20, he recalled in 2001, after encountering difficulties upon losing vision in one eye at age 16. By this time he had begun work as an animation tracer at Audio Productions in the old Edison studios in The Bronx, and advanced to become an in-betweener after the company moved to the Fox Movietone News Building. He then worked four years at the Jam Handy Studio in Detroit, Michigan, contributing, he said, to "films for Chevrolet, and stop-motion pictures, and Technicolor films for the Metropolitan Life Insurance Company. From there, he spent four years in Florida as an animator at Fleischer Brothers Studios, where he worked as an assistant animator on Betty Boop, Popeye and Supermantheatrical shorts and on the animated features Mr. Bug Goes to Town and Gulliver's Travels.
 Passage 2:Gradually, the size of the issues was decreased as the publisher was reluctant to raise the cover price from the original 10 cents, so there were fewer stories. For a while, Congo Bill and Tommy Tomorrow were the two features in addition to Superman. Writer Robert Bernstein and artist Howard Sherman revamped the "Congo Bill" backup feature in issue #248 (January 1959) in a story wherein the character gained the ability to swap bodies with a gorilla and his strip was renamed Congorilla. The introduction of Supergirl by Otto Binder and Al Plastino occurred in issue #252 (May 1959). Following this debut appearance, Supergirl adopted the secret identity of an orphan "Linda Lee" and made Midvale Orphanage her base of operations. In Action Comics #261 (February 1960), her pet cat Streaky was introduced by Jerry Siegel and Jim Mooney. Supergirl joined the Legion of Super-Heroes in issue #276 and acted for three years as Superman's "secret weapon," until her existence was revealed in Action Comics #285 (January 1962). In the view of comics historian Les Daniels, artist Curt Swan became the definitive artist of Superman in the early 1960s with a "new look" to the character that replaced Wayne Boring's version. Bizarro World first appeared in the story "The World of Bizarros!" in issue #262 (April 1960). Writer Jim Shooter created the villain the Parasite in Action Comics #340 (Aug. 1966).
 Passage 3:The islands of Africa can be subdivided into Indian Ocean Islands and Atlantic Ocean Islands. The largest number of islands of Africa are found in the Indian Ocean, with the sovereign island nations of Comoros, Seychelles, Mauritius and Madagascar located off the southeastern seaboard of Africa being the most notable. The French overseas territories of Mayotte and Réunion are also located nearby. The medium-sized islands of Zanzibar and Lamu of Tanzania and Kenya, respectively, are also located in the Indian Ocean, in addition to smaller islands off the coasts of other continental countries. In the Atlantic seaboard, the largest islands are Cape Verde off the coast of West Africa and Sao Tome and Principe off the southwestern seaboard. In the Atlantic Ocean, the island of Malabo and other smaller islands of Equatorial Guinea are also notable. The Canary Islands and other territories of Spain are present in the Mediterranean Sea in the north Atlantic Ocean, and the British possessions of Saint Helena, Ascension Island, and Tristan da Cunha are located off the southwestern seaboard of the continent.
