Input: Consider Input: Passage: The word phonology comes from the Greek , phone, "voice, sound," and the suffix -logy (which is from Greek , logos, "word, speech, subject of discussion"). Definitions of the term vary. Nikolai Trubetzkoy in Grundzuge der Phonologie (1939) defines phonology as "the study of sound pertaining to the system of language," as opposed to phonetics, which is "the study of sound pertaining to the act of speech" (the distinction between language and speech being basically Saussure's distinction between langue and parole). More recently, Lass (1998) writes that phonology refers broadly to the subdiscipline of linguistics concerned with the sounds of language, while in more narrow terms, "phonology proper is concerned with the function, behavior and organization of sounds as linguistic items." According to Clark et al. (2007), it means the systematic use of sound to encode meaning in any spoken human language, or the field of linguistics studying this use. Question: Who in 1939 defined phonology?

Output: Nikolai Trubetzkoy

Input: Consider Input: Passage: A comprehensive school is a state school that does not select its intake on the basis of academic achievement or aptitude. This is in contrast to the selective school system, where admission is restricted on the basis of selection criteria. The term is commonly used in relation to England and Wales, where comprehensive schools were introduced on an experimental basis in the 1940s and became more widespread from 1965. About 90% of British secondary school pupils now attend comprehensive schools. They correspond broadly to the public high school in the United States and Canada and to the German Gesamtschule.[citation needed] Question: What kind of school system uses academic success to judge admissions?

Output: selective school system

Input: Consider Input: Passage: Renaissance humanism took a close study of the Latin and Greek classical texts, and was antagonistic to the values of scholasticism with its emphasis on the accumulated commentaries; and humanists were involved in the sciences, philosophies, arts and poetry of classical antiquity.

By analogy with the perceived decline of Latin, they applied the principle of ad fontes, or back to the sources, across broad areas of learning. Question: What did renaissance humanism place an emphasis on?
Output: accumulated commentaries
