Input: Read this: The Cambrian is a major division of the geologic timescale that begins about 541.0 ± 1.0 Ma. Cambrian continents are thought to have resulted from the breakup of a Neoproterozoic supercontinent called Pannotia. The waters of the Cambrian period appear to have been widespread and shallow. Continental drift rates may have been anomalously high. Laurentia, Baltica and Siberia remained independent continents following the break-up of the supercontinent of Pannotia. Gondwana started to drift toward the South Pole. Panthalassa covered most of the southern hemisphere, and minor oceans included the Proto-Tethys Ocean, Iapetus Ocean and Khanty Ocean.
Question: What continent moved to the southern-most part of the earth in the Cambrian era?

Output: Gondwana


QUES: The Republic of Liberia, beginning as a settlement of the American Colonization Society (ACS), declared its independence on July 26, 1847. The United States did not recognize Liberia's independence until during the American Civil War on February 5, 1862. Between January 7, 1822 and the American Civil War, more than 15,000 freed and free-born Black Americans from United States and 3,198 Afro-Caribbeans relocated to the settlement. The Black American settlers carried their culture with them to Liberia. The Liberian constitution and flag were modeled after the United States. In January 3, 1848 Joseph Jenkins Roberts, a wealthy free-born Black American from Virginia who settled in Liberia, was elected as Liberia's first president after the people proclaimed independence.

How many slaves were freed in the american civil war?
What is the answer?
ANS: more than 15,000


QUES: Electrochemical migration (ECM) is the growth of conductive metal filaments on or in a printed circuit board (PCB) under the influence of a DC voltage bias. Silver, zinc, and aluminum are known to grow whiskers under the influence of an electric field. Silver also grows conducting surface paths in the presence of halide and other ions, making it a poor choice for electronics use. Tin will grow "whiskers" due to tension in the plated surface. Tin-Lead or solder plating also grows whiskers, only reduced by the percentage Tin replaced. Reflow to melt solder or tin plate to relieve surface stress lowers whisker incidence. Another coating issue is tin pest, the transformation of tin to a powdery allotrope at low temperature.
What's the process whereby metal filaments are grown on or in a PCB via DC voltage?

ANS: Electrochemical migration


That said, the score does not provide complete and exact instructions on how to perform a historical work. Even if the tempo is written with an Italian instruction (e.g., Allegro), we do not know exactly how fast the piece should be played. As well, in the Baroque era, many works that were designed for basso continuo accompaniment do not specify which instruments should play the accompaniment or exactly how the chordal instrument (harpsichord, lute, etc.) should play the chords, which are not notated in the part (only a figured bass symbol beneath the bass part is used to guide the chord-playing performer). The performer and/or the conductor have a range of options for musical expression and interpretation of a scored piece, including the phrasing of melodies, the time taken during fermatas (held notes) or pauses, and the use (or choice not to use) of effects such as vibrato or glissando (these effects are possible on various stringed, brass and woodwind instruments and with the human voice).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what era were many works designed for basso continuo accompaniment? 
Ah, so.. the Baroque era


Question: The city is home to 15 am and FM radio stations, two of which are French-language stations. St. John's is the only Canadian city served by radio stations whose call letters do not all begin with the letter C. The ITU prefix VO was assigned to the Dominion of Newfoundland before the province joined Canadian Confederation in 1949, and three AM stations kept their existing call letters. However, other commercial radio stations in St. John's which went to air after 1949 use the same range of prefixes (CF–CK) currently in use elsewhere in Canada, with the exception of VOCM-FM, which was permitted to adopt the VOCM callsign because of its corporate association with the AM station that already bore that callsign. VO also remains in use in amateur radio.
Try to answer this question if possible: What city has 15 am stations
Answer: unanswerable


Input: Read this: In the early Heian period, the late 8th and early 9th centuries, Emperor Kammu sought to consolidate and expand his rule in northern Honshū, but the armies he sent to conquer the rebellious Emishi people lacked motivation and discipline, and failed in their task.[citation needed] Emperor Kammu introduced the title of sei'i-taishōgun (征夷大将軍) or Shogun, and began to rely on the powerful regional clans to conquer the Emishi. Skilled in mounted combat and archery (kyūdō), these clan warriors became the Emperor's preferred tool for putting down rebellions.[citation needed] Though this is the first known use of the "Shogun" title, it was a temporary title, and was not imbued with political power until the 13th century. At this time (the 7th to 9th century) the Imperial Court officials considered them merely a military section under the control of the Imperial Court.
Question: Who did Kammu fail to conquer?

Output:
Emishi
