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.

Input: Consider Input: Question: Who is the CEO of the airline that scheduled flights to several Florida cities and Detroit? Passage:In later years, Continental Express continued to serve the airport with nonstop regional jet flights to Cleveland while Continental Connection was operating nonstop turboprop flights to Albany, NY; however, both services ended in 2005. Spirit Airlines scheduled flights to several Florida cities and Detroit, before moving to LaGuardia Airport in 2001; in May 2008 the airline resumed service to Fort Lauderdale from MacArthur only to drop it soon after. Delta Express, which had nonstops to Orlando and Fort Lauderdale, dropped MacArthur Airport in 2003 after a decline in traffic. Delta Connection regional jet service to Atlanta flown by Atlantic Southeast Airlines (ASA) on behalf of Delta Air Lines ended on May 1, 2008 following a mid-April announcement that Delta and Northwest Airlines were planning to merge – a move that led to changes for the merged airline.

Input: Consider 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.
 Links: a. Antarctic Circumpolar Current b. Dall's porpoise c. Salinity d. Salinity

Output: b


Input: Consider Input: Question: Were the two films that Travers references directed by the same person? Passage:Film critic Roger Ebert wrote that the film was "kind of sweet and kind of goofy, and works because its heart is in the right place". Hal Hinson of The Washington Post said that the film "is hopelessly syrupy, preposterous and more than a little bit lame, but, still, somehow it got to me". Vincent Canby of The New York Times, said that the film "is to the mind what freshly discarded chewing gum is to the sole of a shoe: an irritant that slows movement without any real danger of stopping it". Entertainment Weekly gave the film a "B−" rating and Owen Gleiberman praised Tomei's performance: "With her flashing dark eyes and libidinous overbite, Tomei is adorable — she looks like a flirtatious bunny rabbit — but what's astonishing is the range of expression that passes over those delectable features". Rolling Stone magazine's Peter Travers wrote, "The Rain Man-Dying Young elements in Tom Sierchio's script are pitfalls that Slater dodges with a wonderfully appealing performance. His love scenes with the dazzling Tomei have an uncommon delicacy". In his review for The New Yorker, Anthony Lane praised Tomei for bringing "startling high spirits to a dullish role. She snatches moments of happiness out of the air and shares them out to anyone who’s around". Mike Clark, in his review for USA Today, wrote, "Director Tony Bill (My Bodyguard) is adept both in the yarn's meticulous buildup and in his handling of the actors".
