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.

Example Input: Question: Has the voice actor for the White Rabbit voiced any other characters? Passage:The film follows the storyline of the book closely, save for adding some scenes from Through the Looking-Glass. It also changes the opening real world scene from Alice and her sister sitting at a riverbank to Alice in her bedroom, reluctantly practicing the song "Cherry Ripe", which she is expected to perform at a garden party. (The party guests are played by the same actors as the Wonderland characters and are shown as resembling them in appearance and personality, in a similar manner to the MGM version of The Wizard of Oz. The toys in Alice's room also reflect the residents of Wonderland). Thanks to stage fright and constant nagging from her confident governess (Dilys Laye), Alice runs out of the house and hides herself in the woods nearby, planning to stay hidden until the party has ended. However, an apple floats down from the tree and seems to hover in Alice's face. She is suddenly distracted by a human-sized White Rabbit (voiced by Richard Coombs) rushing by. Curious, Alice follows the White Rabbit, falling down his rabbit hole and ending up in Wonderland.

Example Input: 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.
