Input: 51st state
During World War II, when Denmark was occupied by Nazi Germany, the United States briefly controlled Greenland for battlefields and protection. In 1946, the United States offered to buy Greenland from Denmark for $100 million ($1.2 billion today) but Denmark refused to sell it. Several politicians and others have in recent years argued that Greenland could hypothetically be in a better financial situation as a part of the United States; for instance mentioned by professor Gudmundur Alfredsson at University of Akureyri in 2014. One of the actual reasons behind US interest in Greenland could be the vast natural resources of the island. According to Wikileaks, the U.S. appears to be highly interested in investing in the resource base of the island and in tapping the vast expected hydrocarbons off the Greenlandic coast.

How much did the US offer to pay for Greenland?
Output: $100 million

Input: Madonna (entertainer)
In 1985, Madonna commented that the first song to ever make a strong impression on her was "These Boots Are Made for Walkin'" by Nancy Sinatra; she said it summed up her own "take-charge attitude". As a young woman, she attempted to broaden her taste in literature, art, and music, and during this time became interested in classical music. She noted that her favorite style was baroque, and loved Mozart and Chopin because she liked their "feminine quality". Madonna's major influences include Karen Carpenter, The Supremes and Led Zeppelin, as well as dancers Martha Graham and Rudolf Nureyev. She also grew up listening to David Bowie, whose show was the first rock concert she ever attended.

Whose favorite style is baroque?
Output: Madonna

Input: Literature
A literary technique or literary device can be used by authors in order to enhance the written framework of a piece of literature, and produce specific effects. Literary techniques encompass a wide range of approaches to crafting a work: whether a work is narrated in first-person or from another perspective, whether to use a traditional linear narrative or a nonlinear narrative, or the choice of literary genre, are all examples of literary technique. They may indicate to a reader that there is a familiar structure and presentation to a work, such as a conventional murder-mystery novel; or, the author may choose to experiment with their technique to surprise the reader.

In what type of writing would a more familiar, standard literary narrative structure be employed?
Output: a conventional murder-mystery novel

Input: Korean War
On 1 March 1951 Mao sent a cable to Stalin, in which he emphasized the difficulties faced by Chinese forces and the urgent need for air cover, especially over supply lines. Apparently impressed by the Chinese war effort, Stalin finally agreed to supply two air force divisions, three anti-aircraft divisions, and six thousand trucks. PVA troops in Korea continued to suffer severe logistical problems throughout the war. In late April Peng Dehuai sent his deputy, Hong Xuezhi, to brief Zhou Enlai in Beijing. What Chinese soldiers feared, Hong said, was not the enemy, but that they had nothing to eat, no bullets to shoot, and no trucks to transport them to the rear when they were wounded. Zhou attempted to respond to the PVA's logistical concerns by increasing Chinese production and improving methods of supply, but these efforts were never completely sufficient. At the same time, large-scale air defense training programs were carried out, and the Chinese Air Force began to participate in the war from September 1951 onward.

What did China introduce to the war in 1951?
Output:
the Chinese Air Force
