Input: Read this: The word gymnastics derives from the common Greek adjective γυμνός (gymnos) meaning "naked", by way of the related verb γυμνάζω (gymnazo), whose meaning is to train naked", "train in gymnastic exercise", generally "to train, to exercise". The verb had this meaning, because athletes in ancient times exercised and competed without clothing. It came into use in the 1570s, from Latin gymnasticus, from Greek gymnastikos "fond of or skilled in bodily exercise," from gymnazein "to exercise or train" (see gymnasium).
Question: When did gymnasts start competing with clothing?

Output: unanswerable


QUES: Vowel length is not always considered a distinctive feature in Dutch phonology, because it normally co-occurs with changes in vowel quality. One feature or the other may be considered redundant, and some phonemic analyses prefer to treat it as an opposition of tenseness. However, even if not considered part of the phonemic opposition, the long/tense vowels are still realised as phonetically longer than their short counterparts. The changes in vowel quality are also not always the same in all dialects, and in some there may be little difference at all, with length remaining the primary distinguishing feature. And while it is true that older words always pair vowel length with a change in vowel quality, new loanwords have reintroduced phonemic oppositions of length. Compare zonne(n) [ˈzɔnə] ("suns") versus zone [ˈzɔːnə] ("zone") versus zonen [ˈzoːnə(n)] ("sons"), or kroes [krus] ("mug") versus cruise [kruːs] ("cruise").

What quality of Dutch vowels isn't usually recognized as distinctive?
What is the answer?
ANS: length


QUES: In January 2008 the Wapping presses printed The Sun for the last time and London printing was transferred to Waltham Cross in the Borough of Broxbourne in Hertfordshire, where News International had built what is claimed to be the largest printing centre in Europe with 12 presses. The site also produces The Times and Sunday Times, Daily Telegraph and Sunday Telegraph, Wall Street Journal Europe (also now a Murdoch newspaper), London's Evening Standard and local papers. Northern printing had earlier been switched to a new plant at Knowsley on Merseyside and the Scottish Sun to another new plant at Motherwell near Glasgow. The three print centres represent a £600 million investment by NI and allowed all the titles to be produced with every page in full colour from 2008. The Waltham Cross plant is capable of producing one million copies an hour of a 120-page tabloid newspaper.
When was The Sun printed on the Wapping presses for the last time?

ANS: January 2008


The modern Slavic peoples carry a variety of mitochondrial DNA haplogroups and Y-chromosome DNA haplogroups. Yet two paternal haplogroups predominate: R1a1a [M17] and I2a2a [L69.2=T/S163.2]. The frequency of Haplogroup R1a ranges from 63.39% in the Sorbs, through 56.4% in Poland, 54% in Ukraine, 52% in Russia, Belarus, to 15.2% in Republic of Macedonia, 14.7% in Bulgaria and 12.1% in Herzegovina. The correlation between R1a1a [M17] and the speakers of Indo-European languages, particularly those of Eastern Europe (Russian) and Central and Southern Asia, was noticed in the late 1990s. From this Spencer Wells and colleagues, following the Kurgan hypothesis, deduced that R1a1a arose on the Pontic-Caspian steppe.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where did  I2a2a arise from?
Ah, so.. unanswerable


Question: The early Islamic literature indicates that the conquest of India was one of the very early ambitions of the Muslims, though it was recognized as a particularly difficult one. After conquering Persia, the Arab Umayyad Caliphate incorporated parts of what are now Afghanistan and Pakistan around 720. The book Chach Nama chronicles the Chacha Dynasty's period, following the demise of the Rai Dynasty and the ascent of Chach of Alor to the throne, down to the Arab conquest by Muhammad bin Qasim in the early 8th century AD, by defeating the last Hindu monarch of Sindh, Raja Dahir.
Try to answer this question if possible: What Arab leader completed the early ambitions of Arabs by conquering parts of northern India?
Answer: Muhammad bin Qasim


Input: Read this: The four-year, full-time undergraduate program comprises the majority of enrollments at the university and emphasizes instruction in the arts and sciences, plus the professions of engineering, journalism, communication, music, and education. Although a foundation in the liberal arts and sciences is required in all majors, there is no required common core curriculum; individual degree requirements are set by the faculty of each school. Northwestern's full-time undergraduate and graduate programs operate on an approximately 10-week academic quarter system with the academic year beginning in late September and ending in early June. Undergraduates typically take four courses each quarter and twelve courses in an academic year and are required to complete at least twelve quarters on campus to graduate. Northwestern offers honors, accelerated, and joint degree programs in medicine, science, mathematics, engineering, and journalism. The comprehensive doctoral graduate program has high coexistence with undergraduate programs.
Question: Who sets individual degree requirements at Northwestern?

Output:
the faculty of each school
