Input: Read this: The baroque style had never truly been to the English taste. Four influential books were published in the first quarter of the 18th century which highlighted the simplicity and purity of classical architecture: Vitruvius Britannicus (Colen Campbell 1715), Palladio's Four Books of Architecture (1715), De Re Aedificatoria (1726) and The Designs of Inigo Jones... with Some Additional Designs (1727). The most popular was the four-volume Vitruvius Britannicus by Colen Campbell. The book contained architectural prints of famous British buildings that had been inspired by the great architects from Vitruvius to Palladio. At first the book mainly featured the work of Inigo Jones, but the later tomes contained drawings and plans by Campbell and other 18th-century architects. Palladian architecture became well established in 18th-century Britain.
Question: What book featured the work of an Inigo Jones and other architects from the 1800s?

Output: unanswerable

QUES: The Northwestern library system consists of four libraries on the Evanston campus including the present main library, University Library and the original library building, Deering Library; three libraries on the Chicago campus; and the library affiliated with Garrett-Evangelical Theological Seminary. The University Library contains over 4.9 million volumes, 4.6 million microforms, and almost 99,000 periodicals making it (by volume) the 30th-largest university library in North America and the 10th-largest library among private universities. Notable collections in the library system include the Melville J. Herskovits Library of African Studies, the largest Africana collection in the world, an extensive collection of early edition printed music and manuscripts as well as late-modern works, and an art collection noted for its 19th and 20th-century Western art and architecture periodicals. The library system participates with 15 other universities in digitizing its collections as a part of the Google Book Search project. The Mary and Leigh Block Museum of Art is a major art museum in Chicago, containing more than 4,000 works in its permanent collection as well as dedicating a third of its space to temporary and traveling exhibitions.

What is the largest African collection in the world that is part of the Northwesern library system?
What is the answer?
ANS: Melville J. Herskovits Library of African Studies

QUES: The event was significant not only for Yugoslavia and Tito, but also for the global development of socialism, since it was the first major split between Communist states, casting doubt on Comintern's claims for socialism to be a unified force that would eventually control the whole world, as Tito became the first (and the only successful) socialist leader to defy Stalin's leadership in the COMINFORM. This rift with the Soviet Union brought Tito much international recognition, but also triggered a period of instability often referred to as the Informbiro period. Tito's form of communism was labeled "Titoism" by Moscow, which encouraged purges against suspected "Titoites'" throughout the Eastern bloc.
What name refers to the period of instability during the rift between Tito and the USSR?

ANS: Informbiro

The first ground attack came at the Battle of Umm Qasr on 21 March 2003 when a combined force of British, American and Polish forces seized control of the port city of Umm Qasr. Baghdad, Iraq's capital city, fell to American forces in April 2003 and Saddam Hussein's government quickly dissolved. On 1 May 2003, Bush announced that major combat operations in Iraq had ended. However, an insurgency arose against the U.S.-led coalition and the newly developing Iraqi military and post-Saddam government. The insurgency, which included al-Qaeda affiliated groups, led to far more coalition casualties than the invasion. Other elements of the insurgency were led by fugitive members of President Hussein's Ba'ath regime, which included Iraqi nationalists and pan-Arabists. Many insurgency leaders are Islamists and claim to be fighting a religious war to reestablish the Islamic Caliphate of centuries past. Iraq's former president, Saddam Hussein was captured by U.S. forces in December 2003. He was executed in 2006.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was the Islamic Caliphate executed by US forces?
Ah, so.. unanswerable

Question: The oldest method of studying the brain is anatomical, and until the middle of the 20th century, much of the progress in neuroscience came from the development of better cell stains and better microscopes. Neuroanatomists study the large-scale structure of the brain as well as the microscopic structure of neurons and their components, especially synapses. Among other tools, they employ a plethora of stains that reveal neural structure, chemistry, and connectivity. In recent years, the development of immunostaining techniques has allowed investigation of neurons that express specific sets of genes. Also, functional neuroanatomy uses medical imaging techniques to correlate variations in human brain structure with differences in cognition or behavior.
Try to answer this question if possible: Until what century was brain studying mostly anatomical?
Answer: the middle of the 20th century,

Context and question: This is not to say that Whitehead's thought was widely accepted or even well-understood. His philosophical work is generally considered to be among the most difficult to understand in all of the western canon. Even professional philosophers struggled to follow Whitehead's writings. One famous story illustrating the level of difficulty of Whitehead's philosophy centers around the delivery of Whitehead's Gifford lectures in 192728 following Arthur Eddington's lectures of the year previous which Whitehead would later publish as Process and Reality:
Who also struggled to follow Whitehead's writings?
Answer:
professional philosophers
