Input: Read this: 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: What Greek word is -logy derived from?

Output: logos

QUES: The M. tuberculosis complex (MTBC) includes four other TB-causing mycobacteria: M. bovis, M. africanum, M. canetti, and M. microti. M. africanum is not widespread, but it is a significant cause of tuberculosis in parts of Africa. M. bovis was once a common cause of tuberculosis, but the introduction of pasteurized milk has almost completely eliminated this as a public health problem in developed countries. M. canetti is rare and seems to be limited to the Horn of Africa, although a few cases have been seen in African emigrants. M. microti is also rare and is seen almost only in immunodeficient people, although its prevalence may be significantly underestimated.
Which one of the tuberculosis mycobacteria is associated with the Horn of Africa?

ANS: M. canetti

The center of traditional Uruguayan food and beverage in Montevideo is the Mercado del Puerto ("Port Market"). A torta frita is a pan-fried cake consumed in Montevideo and throughout Uruguay. It is generally circular, with a small cut in the centre for cooking, and is made from wheat flour, yeast, water and sugar or salt. Beef is very important in Uruguayan cuisine and an essential part of many dishes. Montevideo has a variety of restaurants, from traditional Uruguayan cuisine to Japanese cuisine such as sushi. Notable restaurants in Montevideo include Arcadia atop the Plaza Victoria, widely regarded to be the finest restaurant in the city. Arcadia is set in a classic Italian-inspired dining room and serves lavish dishes such as terrine of pheasant marinated in cognac, grilled lamb glazed with mint and garlic, and duck confit on thin strudel pastry with red cabbage. El Fogon is more popular with the late-night diners of the city. Its interior is brightly lit and the walls covered with big mirrors. Officially a barbecue and seafood restaurant, it serves grilled meat dishes, as well as salmon, shrimp and calamari. Also of note is the Cru. Numerous restaurants are located along the Rambla of Montevideo. There is an Irish pub in the eastern part of the Old District named Shannon Irish pub, another testament to the European heritage of the city.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where is Arcadia located?
Ah, so.. atop the Plaza Victoria

Question: In the 11th century and the 12th century, the princes and their retinues, which were a mixture of Slavic and Scandinavian elites, dominated the society of Kievan Rus'. Leading soldiers and officials received income and land from the princes in return for their political and military services. Kievan society lacked the class institutions and autonomous towns that were typical of Western European feudalism. Nevertheless, urban merchants, artisans and labourers sometimes exercised political influence through a city assembly, the veche (council), which included all the adult males in the population. In some cases, the veche either made agreements with their rulers or expelled them and invited others to take their place. At the bottom of society was a stratum of slaves. More important was a class of tribute-paying peasants, who owed labour duty to the princes. The widespread personal serfdom characteristic of Western Europe did not exist in Kievan Rus'.
Try to answer this question if possible: What was widespread in Eastern Europe?
Answer: unanswerable

Input: Read this: In 2006, about 45% of the government's budget came from oil and natural gas revenues, and 31% came from taxes and fees. As of 2007[update], Iran had earned $70 billion in foreign exchange reserves mostly (80%) from crude oil exports. Iranian budget deficits have been a chronic problem, mostly due to large-scale state subsidies, that include foodstuffs and especially gasoline, totaling more than $84 billion in 2008 for the energy sector alone. In 2010, the economic reform plan was approved by parliament to cut subsidies gradually and replace them with targeted social assistance. The objective is to move towards free market prices in a 5-year period and increase productivity and social justice.
Question: How much of Iran's budget came from oil and natural gas reserves in 2006?

Output:
about 45%
