In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

[EX Q]: Question: How many seasons did the television show that Earl Gaines appeared on air? Passage:Breaking away from the confines of the group, Gaines became part of the 1955 R&B Caravan of Stars, with Bo Diddley, Big Joe Turner, and Etta James. Their tour culminated with an appearance at New York's Carnegie Hall. Without any tangible success, Gaines recorded for the Champion and Poncello labels for another few years, as well as joining Bill Doggett's band as lead vocalist. In 1963, he joined Bill "Hoss" Allen's repertoire of artists, and by 1966 had issued the album The Best of Luck to You, seeing the title track reach the Top 40 in the US R&B chart. He appeared on the television program The !!!! Beat, and later released material for King and Sound Stage 7, including his cover version of "Hymn Number 5". Recordings made between 1967 and 1973 for De Luxe were reissued in 1998. On many of his De Luxe recordings in the late 1960s and early 1970s, Gaines was backed by Freddy Robinson's orchestra.

[EX Q]: Question: What's the average lifespan of the animal that has a jaw with properties similar to those that probably led to the evolution of baleen? Passage:The oldest true fossils of baleen are only 15 million years old because baleen rarely fossilizes, and scientists believe it originated considerably earlier than that. This is indicated by baleen-related skull modifications being found in fossils from considerably earlier, including a buttress of bone in the upper jaw beneath the eyes, and loose lower jaw bones at the chin. Baleen is believed to have evolved around 30 million years ago, possibly from a hard, gummy upper jaw, like the one a Dall's porpoise has; it closely resembles baleen at the microscopic level. The initial evolution and radiation of baleen plates is believed to have occurred during Early Oligocene when Antarctica broke off from Gondwana and the Antarctic Circumpolar Current was formed, increasing productivity of ocean environments. This occurred because the current kept warm ocean waters away from the area that is now Antarctica, producing steep gradients in temperature, salinity, light, and nutrients, where the warm water meets the cold.
