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.

[Q]: Question: Which of Hyam's male co-stars in Alias Jimmy Valentine was the oldest? Passage:She made her first film in 1924, and with her blonde hair, green eyes, delicate features, and good-natured demeanor, was cast in a string of supporting roles, where she was required to do very little but smile and look pretty. She proved herself capable of handling the small roles she was assigned, and over a period of time, she came to be taken seriously as an actress. By 1928, she was playing starring roles, achieving success in MGM's first talkie release, Alias Jimmy Valentine (1928) opposite William Haines, Lionel Barrymore, and Karl Dane. The following year, she appeared in the popular murder mystery The Thirteenth Chair, a role that offered her the chance to display her dramatic abilities as a murder suspect. At Fox that same year, she appeared in director Allan Dwan's now lost romantic adventure The Far Call opposite Charles Morton. The quality of her parts continued to improve as the decade turned, including a role as Robert Montgomery's sister in the prison drama The Big House (1930) with Chester Morris and Wallace Beery, for which Hyams once again received positive reviews. She then appeared in Surrender (1931) in which Warner Baxter and Ralph Bellamy desperately competed for her attention.

[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.

[Q]: Question: Is the person who discovered Pluto an American? Passage:Pluto was discovered by Clyde W. Tombaugh on 18 February 1930. When Pluto was first discovered, it was initially known as Planet X. Astronomers had been searching for another planet past Neptune, hoping to solve the dilemma of its rather irregular orbit. It is now known, however, that the perceived irregular orbit of Neptune was the result of a mathematical error because Pluto, being a planetoid smaller than our own Moon, was far too small to affect any type of gravitational pull on the gas giant. Pluto is very much a 20th-century planet and refers to the two world wars, and weapons of mass destruction, nuclear power, and a desire to totally control the world we live in. It is a planet that reveals to us the extremes we are capable of if we do not set necessary boundaries in our lives. This planet governs the compulsions in our life: those things we are compelled to do but know we should not, such as murder, rape, drug addiction, and even overeating if it is of such an extent that it threatens our health. Pluto is considered to be a higher octave of Mars, and this is evidenced by the fact that both planets co-rule Scorpio. Pluto, circling the Sun in 248 years, has a rather elliptical orbit, which means that it stays in the sign it rules, Scorpio, for a mere 9 years, and the sign of its fall, Taurus for 30! With this in mind, some astrologers believe that Pluto should rightfully rule Taurus, but for the time being it still rules Scorpio. As other trans-Neptunian object planets are discovered, however, this placement just might have to be reconsidered.
