Input: Late Middle Ages
Around 1300, centuries of prosperity and growth in Europe came to a halt. A series of famines and plagues, including the Great Famine of 1315–1317 and the Black Death, reduced the population to around half of what it was before the calamities. Along with depopulation came social unrest and endemic warfare. France and England experienced serious peasant uprisings, such as the Jacquerie and the Peasants' Revolt, as well as over a century of intermittent conflict in the Hundred Years' War. To add to the many problems of the period, the unity of the Catholic Church was shattered by the Western Schism. Collectively these events are sometimes called the Crisis of the Late Middle Ages.

What are the series of events that ended centuries of prosperity in Europe, starting around 1300, known as?
Output: the Crisis of the Late Middle Ages

Input: Kanye West
During a November 26, 2013 radio interview, West explained why he believed that President Obama had problems pushing policies in Washington: "Man, let me tell you something about George Bush and oil money and Obama and no money. People want to say Obama can't make these moves or he's not executing. That's because he ain't got those connections. Black people don't have the same level of connections as Jewish people...We ain't Jewish. We don't got family that got money like that." In response to his comments, the Anti-Defamation League stated: "There it goes again, the age-old canard that Jews are all-powerful and control the levers of power in government." On December 21, 2013, West backed off of the original comment and told a Chicago radio station that "I thought I was giving a compliment, but if anything it came off more ignorant. I don’t know how being told you have money is an insult."

What president did Kanye comment on as having trouble pushing policies while in office?
Output: Obama

Input: Green
Animals typically use the color green as camouflage, blending in with the chlorophyll green of the surrounding environment. Green animals include, especially, amphibians, reptiles, and some fish, birds and insects. Most fish, reptiles, amphibians, and birds appear green because of a reflection of blue light coming through an over-layer of yellow pigment. Perception of color can also be affected by the surrounding environment. For example, broadleaf forests typically have a yellow-green light about them as the trees filter the light. Turacoverdin is one chemical which can cause a green hue in birds, especially. Invertebrates such as insects or mollusks often display green colors because of porphyrin pigments, sometimes caused by diet. This can causes their feces to look green as well. Other chemicals which generally contribute to greenness among organisms are flavins (lychochromes) and hemanovadin. Humans have imitated this by wearing green clothing as a camouflage in military and other fields. Substances that may impart a greenish hue to one's skin include biliverdin, the green pigment in bile, and ceruloplasmin, a protein that carries copper ions in chelation.

What is a chemical that can cause green hue in birds?
Output: Turacoverdin

Input: Textual criticism
Bowers confronted a similar problem in his edition of Maggie. Crane originally printed the novel privately in 1893. To secure commercial publication in 1896, Crane agreed to remove profanity, but he also made stylistic revisions. Bowers's approach was to preserve the stylistic and literary changes of 1896, but to revert to the 1893 readings where he believed that Crane was fulfilling the publisher's intention rather than his own. There were, however, intermediate cases that could reasonably have been attributed to either intention, and some of Bowers's choices came under fire – both as to his judgment, and as to the wisdom of conflating readings from the two different versions of Maggie.

What was the second step Bowers took in editing a single work with two versions?
Output:
to revert to the 1893 readings where he believed that Crane was fulfilling the publisher's intention
