Input: Read this: The most extreme case was the Soviet Union, and this model may still be followed in some countries: it was a separate service, on a par with the navy or ground force. In the Soviet Union this was called Voyska PVO, and had both fighter aircraft and ground-based systems. This was divided into two arms, PVO Strany, the Strategic Air defence Service responsible for Air Defence of the Homeland, created in 1941 and becoming an independent service in 1954, and PVO SV, Air Defence of the Ground Forces. Subsequently these became part of the air force and ground forces respectively
Question: What year did the PVO Strany become independent?

Output: 1954


QUES: Major outputs for the state include textiles, cotton, cattle, and electrical power. Tennessee has over 82,000 farms, roughly 59 percent of which accommodate beef cattle. Although cotton was an early crop in Tennessee, large-scale cultivation of the fiber did not begin until the 1820s with the opening of the land between the Tennessee and Mississippi Rivers. The upper wedge of the Mississippi Delta extends into southwestern Tennessee, and it was in this fertile section that cotton took hold. Soybeans are also heavily planted in West Tennessee, focusing on the northwest corner of the state.

Roughly how many farms are located in Tennesee?
What is the answer?
ANS: 82,000


QUES: Unlike other European nations, the Dutch chose not to follow a policy of language expansion amongst the indigenous peoples of their colonies. In the last quarter of the 19th century, however, a local elite gained proficiency in Dutch so as to meet the needs of expanding bureaucracy and business. Nevertheless, the Dutch government remained reluctant to teach Dutch on a large scale for fear of destabilising the colony. Dutch, the language of power, was supposed to remain in the hands of the leading elite.
Towards the end of what century did it become important for more people in Dutch colonies to speak Dutch?

ANS: 19th


Adventurer and poet Luís de Camões (c. 1524–1580) wrote the epic poem "Os Lusíadas" (The Lusiads), with Virgil's Aeneid as his main influence. Modern Portuguese poetry is rooted in neoclassic and contemporary styles, as exemplified by Fernando Pessoa (1888–1935). Modern Portuguese literature is represented by authors such as Almeida Garrett, Camilo Castelo Branco, Eça de Queiroz, Fernando Pessoa, Sophia de Mello Breyner Andresen, António Lobo Antunes and Miguel Torga. Particularly popular and distinguished is José Saramago, recipient of the 1998 Nobel Prize in Literature.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was Luís de Camões main influence?
Ah, so.. Virgil's Aeneid


Question: A number of technologies allow asphalt/bitumen to be mixed at much lower temperatures. These involve mixing with petroleum solvents to form "cutbacks" with reduced melting point, or mixtures with water to turn the asphalt/bitumen into an emulsion. Asphalt emulsions contain up to 70% asphalt/bitumen and typically less than 1.5% chemical additives. There are two main types of emulsions with different affinity for aggregates, cationic and anionic. Asphalt emulsions are used in a wide variety of applications. Chipseal involves spraying the road surface with asphalt emulsion followed by a layer of crushed rock, gravel or crushed slag. Slurry seal involves the creation of a mixture of asphalt emulsion and fine crushed aggregate that is spread on the surface of a road. Cold-mixed asphalt can also be made from asphalt emulsion to create pavements similar to hot-mixed asphalt, several inches in depth and asphalt emulsions are also blended into recycled hot-mix asphalt to create low-cost pavements.
Try to answer this question if possible: What are the two types of bitumen emulsions?
Answer: cationic and anionic


Question: Around the second century BC the first-known city-states emerged in central Myanmar. The city-states were founded as part of the southward migration by the Tibeto-Burman-speaking Pyu city-states, the earliest inhabitants of Myanmar of whom records are extant, from present-day Yunnan. The Pyu culture was heavily influenced by trade with India, importing Buddhism as well as other cultural, architectural and political concepts which would have an enduring influence on later Burmese culture and political organisation.
Try to answer this question if possible: From what people have were the first records known to be existent derived from? 
Answer:
from present-day Yunnan
