Input: Read this: The armillary sphere, a three-dimensional representation of the movements in the celestial sphere, was invented in Han China by the 1st century BC. Using a water clock, waterwheel and a series of gears, the Court Astronomer Zhang Heng (78–139 AD) was able to mechanically rotate his metal-ringed armillary sphere. To address the problem of slowed timekeeping in the pressure head of the inflow water clock, Zhang was the first in China to install an additional tank between the reservoir and inflow vessel. Zhang also invented a seismometer (Houfeng didong yi 候风地动仪) in 132 AD to detect the exact cardinal or ordinal direction of earthquakes from hundreds of kilometers away. This employed an inverted pendulum that, when disturbed by ground tremors, would trigger a set of gears that dropped a metal ball from one of eight dragon mouths (representing all eight directions) into a metal toad's mouth.
Question: In what year was the seismometer first invented?

Output: 132 AD


Input: Read this: At over 5 million, Puerto Ricans are easily the 2nd largest Hispanic group. Of all major Hispanic groups, Puerto Ricans are the least likely to be proficient in Spanish, but millions of Puerto Rican Americans living in the U.S. mainland nonetheless are fluent in Spanish. Puerto Ricans are natural-born U.S. citizens, and many Puerto Ricans have migrated to New York City, Orlando, Philadelphia, and other areas of the Eastern United States, increasing the Spanish-speaking populations and in some areas being the majority of the Hispanophone population, especially in Central Florida. In Hawaii, where Puerto Rican farm laborers and Mexican ranchers have settled since the late 19th century, 7.0 per cent of the islands' people are either Hispanic or Hispanophone or both.
Question: Puerto Ricans are citizens of what country?

Output: unanswerable


Input: Read this: In 1839 Mariano Spada (1796 - 1872), professor of theology at the Roman College of Saint Thomas, published Esame Critico sulla dottrina dell’ Angelico Dottore S. Tommaso di Aquino circa il Peccato originale, relativamente alla Beatissima Vergine Maria [A critical examination of the doctrine of St. Thomas Aquinas, the Angelic Doctor, regarding original sin with respect to the Most Blessed Virgin Mary], in which Aquinas is interpreted not as treating the question of the Immaculate Conception later formulated in the papal bull Ineffabilis Deus but rather the sanctification of the fetus within Mary's womb. Spada furnished an interpretation whereby Pius IX was relieved of the problem of seeming to foster a doctrine not in agreement with the Aquinas' teaching. Pope Pius IX would later appoint Spada Master of the Sacred Palace in 1867.
Question: What  problem did the teacher's publication solve for the Holy Roman leader with act that was committed  to do in response to the actions of the teacher  ?

Output: Pius IX was relieved of the problem of seeming to foster a doctrine not in agreement with the Aquinas' teaching.


Input: Read this: The first recorded use of the term (or its cognates in other languages) is in the New Testament, in Acts 11:26, after Barnabas brought Saul (Paul) to Antioch where they taught the disciples for about a year, the text says: "[...] the disciples were called Christians first in Antioch." The second mention of the term follows in Acts 26:28, where Herod Agrippa II replied to Paul the Apostle, "Then Agrippa said unto Paul, Almost thou persuadest me to be a Christian."

Question: In which book of the Old Testament does Paul reply to Herod Agrippa?

Output:
unanswerable
