Input: Read this: Another group of residences, known as the Village, is located in the northwest corner of Danforth Campus. Only open to upperclassmen and January Scholars, the North Side consists of Millbrook Apartments, The Village, Village East on-campus apartments, and all fraternity houses except the Zeta Beta Tau house, which is off campus and located just northwest of the South 40. Sororities at Washington University do not have houses by their own accord. The Village is a group of residences where students who have similar interests or academic goals apply as small groups of 4 to 24, known as BLOCs, to live together in clustered suites along with non-BLOCs. Like the South 40, the residences around the Village also surround a recreational lawn.
Question: How many sororities are there at Washington University?

Output: unanswerable


Input: Read this: The traditional Charleston accent has long been noted in the state and throughout the South. It is typically heard in wealthy white families who trace their families back generations in the city. It has ingliding or monophthongal long mid-vowels, raises ay and aw in certain environments, and is nonrhotic. Sylvester Primer of the College of Charleston wrote about aspects of the local dialect in his late 19th-century works: "Charleston Provincialisms" (1887)  and "The Huguenot Element in Charleston's Provincialisms", published in a German journal. He believed the accent was based on the English as it was spoken by the earliest settlers, therefore derived from Elizabethan England and preserved with modifications by Charleston speakers. The rapidly disappearing "Charleston accent" is still noted in the local pronunciation of the city's name. Some elderly (and usually upper-class) Charleston natives ignore the 'r' and elongate the first vowel, pronouncing the name as "Chah-l-ston". Some observers attribute these unique features of Charleston's speech to its early settlement by French Huguenots and Sephardic Jews (who were primarily English speakers from London), both of whom played influential roles in Charleston's early development and history.[citation needed]
Question: To which college did Sylvester Primer belong?

Output: College of Charleston


Input: Read this: Later interpretations of Avicenna's philosophy split into three different schools; those (such as al-Tusi) who continued to apply his philosophy as a system to interpret later political events and scientific advances; those (such as al-Razi) who considered Avicenna's theological works in isolation from his wider philosophical concerns; and those (such as al-Ghazali) who selectively used parts of his philosophy to support their own attempts to gain greater spiritual insights through a variety of mystical means. It was the theological interpretation championed by those such as al-Razi which eventually came to predominate in the madrasahs.
Question: Who used only parts of Avicenna's works to reject their own great spiritual insights?
