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: How many President's children have lived in the White House? Passage:Within weeks, many Americans could recite favorite lines from the record, including "the rubber schwan [swan] is mine", and "move ahead...with great vigah [vigor]", the latter lampooning the President's own words. The album poked fun at Kennedy's PT-109 history; the rocking chairs he used for his painful back; the Kennedy clan's well-known athleticism, football games and family togetherness; children in the White House; and Jackie Kennedy's soft-spoken nature and her redecoration of the White House; and many other bits of knowledge that the public was eager to consume. Kennedy himself was said to have given copies of the albums as Christmas gifts, and once greeted a Democratic National Committee group by saying, "Vaughn Meader was busy tonight, so I came myself." According to UPI reporter Merriman Smith, during a Cabinet meeting Kennedy played the entire record for everyone. At one press conference, Kennedy was asked if the album had produced "annoyment (sic) or enjoyment." He jokingly responded, "I listened to Mr. Meader's record and, frankly, I thought it sounded more like Teddy than it did me. So, now he's annoyed."

Example Input: Question: How wide is the body of water that separates the Eurasian and North American continents? Passage:The Russian Empire began its interest of the Pacific Northwest in the 18th century, initially curious if there was a land connection between the Eurasian and North American Continents. Two expeditions were led by Vitus Bering, with the findings proving the separation of two continents through the Bering Sea. Being the first European nation to chart much of what comprises the modern American state of Alaska, many locations retain Russian place names. The discovery of sizable fur bearing populations by Bering drew the attention of promyshlenniki previously engaged in the Siberian fur trade. Based out of the Siberian ports of Okhotsk or Petropavlovsk, fur trappers sailed and reported the location of land formations like the Aleutian Islands, Kodiak Island and portions of the Alaskan mainland. Relations with Native Alaskans was often terse due to the uncontrolled actions of particular promyshlenniki who killed and raped Indigenous on islands they trapped furs.

Example Input: Question: What actor played Daniel Romalotti? Passage:Abby protested in front the lobby of Jabot Cosmetics after Tucker McCall became the company owner. Abby did not know that her mother returned to become CEO. Then, Abby planned to start her own reality television show, entitled "The Naked Heiress", but she didn't have the money to fund her dream. After her parents refused to help her, Abby hired Rafe Torres as her lawyer to sue her parents for her inheritance. Soon after, she began flirting with Daniel Romalotti. When Billy and Victoria Newman Abbott refused to help Abby with her reality television dream, she blackmailed Billy in order to be featured in his magazine, Restless Style. She eventually revealed Billy and Victoria's secret Jamaican marriage to their family and friends. Seemingly unstoppable, the judge then denied Abby's plea for her inheritance. Meanwhile, Abby had sex with Daniel in the Newman pool house, and she recorded it for her reality show. Abby and Daniel's relationship was outed when Nikki Newman and Daniel's mother, Phyllis Summers, saw Abby and Daniel making out in public. Their relationship continued for a while, but when Abby found out that Daniel fathered a child with Daisy Carter, she broke up with him. After she witnessed her mother kissing Tucker McCall, she asked him to go into business with her. When Tucker turned her down, Abby decided to take a bubble bath in Katherine Chancellor's pool at the annual Chancellor Fourth of July party. Abby's inheritance was then withheld indefinitely. To spite her parents, Abby rode a horse, while naked, inside the Genoa City Athletic Club while Victor and Nikki were celebrating their engagement. She was arrested and thrown in jail. Upon her release, Abby decided to reopen her lawsuit against Victor, with the help of her uncle Jack Abbott. Later, Abby's half-siblings Victoria and Nicholas Newman joined her in her lawsuit. Victor tried to bargain with his children, but they wanted his cosmetics line, Beauty of Nature. He refused their offer, and with the help of testimonies from their estranged half-brother Adam Newman and Neil Winters, they each received $500 million in the settlement.
