Input: Read this: In the United States, there was a movement to resettle American free blacks and freed slaves in Africa. The American Colonization Society was founded in 1816 in Washington, DC for this purpose, by a group of prominent politicians and slaveholders. But its membership grew to include mostly people who supported abolition of slavery. Slaveholders wanted to get free people of color out of the South, where they were thought to threaten the stability of the slave societies. Some abolitionists collaborated on relocation of free blacks, as they were discouraged by discrimination against them in the North and believed they would never be accepted in the larger society. Most African Americans, who were native-born by this time, wanted to improve conditions in the United States rather than emigrate. Leading activists in the North strongly opposed the ACS, but some free blacks were ready to try a different environment.
Question: When was the "american colonization society founded"?

Output: 1816

Input: Read this: Colin Humphreys and W. G. Waddington of Oxford University considered the possibility that a lunar, rather than solar, eclipse might have taken place. They concluded that such an eclipse would have been visible, for thirty minutes, from Jerusalem and suggested the gospel reference to a solar eclipse was the result of a scribe wrongly amending a text. Historian David Henige dismisses this explanation as 'indefensible' and astronomer Bradley Schaefer points out that the lunar eclipse would not have been visible during daylight hours.
Question: For how many minutes did David Henige belive the lunar eclipse would be visible?

Output: unanswerable

Input: Read this: It had been found that the proportion of non-repetitive DNA can vary a lot between species. Some E. coli as prokaryotes only have non-repetitive DNA, lower eukaryotes such as C. elegans and fruit fly, still possess more non-repetitive DNA than repetitive DNA. Higher eukaryotes tend to have more repetitive DNA than non-repetitive ones. In some plants and amphibians, the proportion of non-repetitive DNA is no more than 20%, becoming a minority component.
Question: What is the percentage of non-repetitive DNA in some plant and amphibian genomes?

Output: 20%

Input: Read this: Karlheinz Brandenburg used a CD recording of Suzanne Vega's song "Tom's Diner" to assess and refine the MP3 compression algorithm. This song was chosen because of its nearly monophonic nature and wide spectral content, making it easier to hear imperfections in the compression format during playbacks. Some refer to Suzanne Vega as "The mother of MP3". This particular track has an interesting property in that the two channels are almost, but not completely, the same, leading to a case where Binaural Masking Level Depression causes spatial unmasking of noise artifacts unless the encoder properly recognizes the situation and applies corrections similar to those detailed in the MPEG-2 AAC psychoacoustic model. Some more critical audio excerpts (glockenspiel, triangle, accordion, etc.) were taken from the EBU V3/SQAM reference compact disc and have been used by professional sound engineers to assess the subjective quality of the MPEG Audio formats.
Question: What word describes the nature of the song used?

Output:
monophonic
