Input: Middle Ages
Romanesque art, especially metalwork, was at its most sophisticated in Mosan art, in which distinct artistic personalities including Nicholas of Verdun (d. 1205) become apparent, and an almost classical style is seen in works such as a font at Liege, contrasting with the writhing animals of the exactly contemporary Gloucester Candlestick. Large illuminated bibles and psalters were the typical forms of luxury manuscripts, and wall-painting flourished in churches, often following a scheme with a Last Judgement on the west wall, a Christ in Majesty at the east end, and narrative biblical scenes down the nave, or in the best surviving example, at Saint-Savin-sur-Gartempe, on the barrel-vaulted roof.

What notable Romanesque metalwork is named for Gloucester?
Output: Gloucester Candlestick

Input: Textual criticism
While textual criticism developed into a discipline of thorough analysis of the Bible both the Hebrew Bible and the New Testament scholars also use it to determine the original content of classic texts, such as Plato's Republic. There are far fewer witnesses to classical texts than to the Bible, so scholars can use stemmatics and, in some cases, copy text editing. However, unlike the New Testament where the earliest witnesses are within 200 years of the original, the earliest existing manuscripts of most classical texts were written about a millennium after their composition. All things being equal, textual scholars expect that a larger time gap between an original and a manuscript means more changes in the text.

Does the Bible or Plato's Republic have more witnesses?
Output: There are far fewer witnesses to classical texts than to the Bible

Input: Solar energy
Solar water disinfection (SODIS) involves exposing water-filled plastic polyethylene terephthalate (PET) bottles to sunlight for several hours. Exposure times vary depending on weather and climate from a minimum of six hours to two days during fully overcast conditions. It is recommended by the World Health Organization as a viable method for household water treatment and safe storage. Over two million people in developing countries use this method for their daily drinking water.

What does the World Health Organization say about Solar water disinfection?
Output: a viable method for household water treatment and safe storage

Input: Black people
By that time, the majority of black people in the United States were native-born, so the use of the term "African" became problematic. Though initially a source of pride, many blacks feared that the use of African as an identity would be a hindrance to their fight for full citizenship in the US. They also felt that it would give ammunition to those who were advocating repatriating black people back to Africa. In 1835, black leaders called upon Black Americans to remove the title of "African" from their institutions and replace it with "Negro" or "Colored American". A few institutions chose to keep their historic names, such as the African Methodist Episcopal Church. African Americans popularly used the terms "Negro" or "colored" for themselves until the late 1960s.

What terms did African Americans use instead?
Output:
"Negro" or "colored"
