Example 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.

Example Input: Question: When did the Sassanids replace the Parthians? Passage:In 270 the Roman emperor Aurelian engaged the Sassanids, who had now replaced the Parthians, on the eastern front and he was able to drive them back. Tiridates, as the true heir to the now Persian-occupied Armenian throne, came to Armenia and quickly raised an army and drove the enemy out in 287. When Tiridates returned to Armenia, he made the city of Vagharshapat his capital, as it had been the capital of his late father. For a while, fortune appeared to favour Tiridates. He not only expelled his enemies, but he carried his arms into Assyria. At the time the Persian Empire was in a distracted state. The throne was disputed by the ambition of two contending brothers, Hormuz and Narses. The civil war was, however, soon terminated and Narses was universally acknowledged as King of Persia. Narses then directed his whole force against the foreign enemy. The contest then became too unequal. Tiridates once more took refuge with the Romans. The Roman-Armenian alliance grew stronger, especially while Diocletian ruled the empire. This can be attributed to the upbringing of Tiridates, the consistent Persian aggressions and the murder of his father by Anak. With Diocletian's help, Tiridates pushed the Persians out of Armenia. In 299, Diocletian left the Armenian state in a quasi-independent and protectorate status possibly to use it as a buffer in case of a Persian attack. Tiridates married an Alani Princess called Ashkhen in 297 by whom he had three children: a son called Khosrov III, a daughter called Salome and an unnamed daughter who married St. Husik I, one of the earlier Catholicoi of the Armenian Apostolic Church.

Example Input: Question: Which of the two teams Thomas was driving to Kansas City International Airport to see during has won the most Superbowls? Passage:On January 23, 2000, Thomas's 1999 Chevrolet Suburban went off Interstate 435 as he and two passengers were driving to Kansas City International Airport during a snowstorm for a flight to St. Louis to watch the between the St. Louis Rams and the Tampa Bay Buccaneers. Police reports indicated that Thomas, who was driving, was speeding at approximately 70 m.p.h. even though snow and ice were rapidly accumulating on the roadway. Thomas continued weaving erratically through traffic despite the weather. Thomas and one of the passengers were not wearing seat belts and both were thrown from the car; the passenger was killed instantly. The second passenger, who was wearing his safety belt, walked away from the scene uninjured. Thomas was left paralyzed from the chest down. By early February, Thomas was being treated at Miami's Jackson Memorial Hospital. The morning of February 8, 2000, while being transferred from his hospital bed to a wheelchair on his way to therapy, Thomas told his mother he was not feeling well. His eyes then rolled back, recalled Frank Eismont, an orthopedic surgeon at Jackson Memorial Hospital. Eismont said Thomas went into cardiorespiratory arrest and died as a result of a pulmonary embolism, a massive blood clot that developed in his legs and traveled to his lungs. Months later, Thomas' family sued General Motors for $73 million in damages stemming from the accident that Thomas caused. In 2004, a jury ruled that the family was not entitled to any money.
