Input: Consider Input: Question: Is Carl Linnaeus older than the French zoologist who introduced the horned screamer in the genus Anhima? Passage:The horned screamer was described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae. He introduced the binomial name Palamedea cornuta. The horned screamer is now the only species placed in the genus Anhima that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The specific epithet cornuta is the Latin word for "horned". The German naturalist Georg Marcgrave had used the Latin name Anhima in 1648 for the horned screamer in his Historia naturalis Brasiliae. The name was from the word for the bird in the Tupi language of South America.

Input: Consider Input: Question: How old was Harrison when he won the Presidency? Passage:Beginning with the 2000 election, the status of the Missouri bellwether came into question. Between 1904 and 2004, Missouri was carried by the victor of each presidential election, with the exception of 1956. Though Bush won the presidency in the 2000 election through the Electoral College, he lost the national popular vote. The 2000 election was unique because this was the first time in over a century where the popular vote winner lost the general election. (In 1888, Missouri voted for Grover Cleveland, the incumbent Democrat, who lost to Republican candidate Benjamin Harrison). Thus, controversy exists as to whether or not Missouri accurately predicted victor in this election. In the subsequent election, Missouri voted for George W. Bush, who this time won both the popular vote and the Electoral College. Missouri has voted reliably Republican since 2000. The state voted for John McCain in 2008, and for Mitt Romney in 2012, both of whom lost the general election to Barack Obama. The controversy is further complicated by the 2016 presidential election, where Missouri voted for Donald Trump by a landslide, while Hillary Clinton won the popular vote by nearly three million votes, but like in 2000, Trump won the Electoral College and became 45th President of the United States. Like 2000, political scientists have differing opinions on whether or not Missouri accurately predicted the victor, and even if Missouri is still a bellwether state at all.

Input: Consider Input: Question: Who does Sierra Rose think is her father? Passage:Stacy Morasco, younger sister to Gigi, is first seen on February 6, 2009 as a Las Vegas stripper named "Gigi." She begins spying on Gigi and Rex Balsom, later following them back to Llanview. Gigi is thrilled to see her, but devastated by the news that their parents had died in a car crash years before, and Stacy's own struggles since. Stacy makes fast friends with Gigi and Rex's son Shane, although Gigi is somewhat uncomfortable with Stacy's influence. Gigi also begins to suspect that her sister is trying to seduce Rex. After Shane is diagnosed with leukemia in March 2009, Stacy learns of a matching donor. Wanting Rex for herself, she pretends that she is the match and forces Gigi to break up with Rex in exchange for her blood. Shane receives the transplant and improves, but Gigi is afraid to reveal Stacy's blackmail in case Shane needs more of her stem cells. Eventually, Gigi tells the truth, but in the meantime Stacy and Rex have slept together. Rex and Gigi reunite as Stacy's blackmail is revealed. Rex spurns Stacy, but she discovers that she is pregnant. She miscarries but keeps the truth from Rex knowing that it is her only hold over him. Stacy calls her stripper best friend Kimberly Andrews to come to Llanview, who comes up with a plan to help get Stacy pregnant again to pass the baby off as Rex's. She drugs ex-boyfriend Schuyler Joplin but he refuses her. She becomes pregnant after seducing a drunken Oliver Fish. In November 2009 Schuyler finds out that Stacy lost her baby with Rex, and Kim tells Schuyler that he is the baby's father. Schuyler agrees to keep the truth from Rex so that he can have Gigi for himself. In January 2010 Rex's crazed biological father Mitch Laurence tries to kidnap Stacy to raise her baby as his heir. Kim and Stacy tells Schuyler to steal a drug called oxytocin so Stacy can give birth a month before her due date to pass the baby as Rex's. On February 2, 2010 Stacy is kidnapped by Mitch Laurence. When she reveals that the baby is not Rex's, Mitch abandons Stacy in a blizzard. Gigi finds her, takes her to a cabin, and on February 11, 2010 helps Stacy deliver a baby girl she names Sierra Rose. On February 16, 2010, Stacy falls through the ice of a frozen lake; despite Rex and Oliver's attempts to save her, she disappears beneath the ice and is presumed dead. Days later, Stacy's spirit appears to Kim several times to get Kim's assurance that she will do all she can to care for Sierra.
