In the far eastern part of the state the Chihuahuan Desert dominates due to low precipitation and extremely high temperatures; some areas of the eastern part of the state are so dry no vegetation is found like the Sand Dunes of Samalayuca. There are two distinctive climate zones found in the eastern part of the state: Hot Desert (BWh) and Cool Desert (BWk) which are differentiated by average annual temperature due to differences in elevation. There is a transition zone in the middle of the state between the two extremely different climates from the east and west; this zone is the Steppe characterized by a compromise between juxtaposed climate zones.
Both types of climate zones in the eastern part of the state are what?
Desert


Input: Paris
After a tentative creation of several smaller suburban cemeteries, the Prefect Nicholas Frochot under Napoleon Bonaparte provided a more definitive solution in the creation of three massive Parisian cemeteries outside the city limits. Open from 1804, these were the cemeteries of Père Lachaise, Montmartre, Montparnasse, and later Passy; these cemeteries became inner-city once again when Paris annexed all neighbouring communes to the inside of its much larger ring of suburban fortifications in 1860. New suburban cemeteries were created in the early 20th century: The largest of these are the Cimetière parisien de Saint-Ouen, the Cimetière parisien de Pantin (also known as Cimetière parisien de Pantin-Bobigny, the Cimetière parisien d'Ivry, and the Cimetière parisien de Bagneux).[citation needed] Some of the most famous people in the world are buried in Parisian cemeteries.

Who was Prefect Nicholas Frochot under?
Output: Napoleon Bonaparte


Input: Article: Roads in the US have been paved with materials that include asphalt/bitumen since at least 1870, when a street in front of the Newark, NJ City Hall was paved. In many cases, these early pavings were made from naturally occurring "bituminous rock", such as at Ritchie Mines in Macfarlan in Ritchie County, West Virginia from 1852 to 1873. In 1876, asphalt-based paving was used to pave Pennsylvania Avenue in Washington, DC, in time for the celebration of the national centennial. Asphalt/bitumen was also used for flooring, paving and waterproofing of baths and swimming pools during the early 20th century, following similar trends in Europe.

Now answer this question: Since what date has asphalt been used for road paving in the US?

Output: 1870


Article: The shelter of the early people changed dramatically from the paleolithic to the neolithic era. In the paleolithic, people did not normally live in permanent constructions. In the neolithic, mud brick houses started appearing that were coated with plaster. The growth of agriculture made permanent houses possible. Doorways were made on the roof, with ladders positioned both on the inside and outside of the houses. The roof was supported by beams from the inside. The rough ground was covered by platforms, mats, and skins on which residents slept. Stilt-houses settlements were common in the Alpine and Pianura Padana (Terramare) region. Remains have been found at the Ljubljana Marshes in Slovenia and at the Mondsee and Attersee lakes in Upper Austria, for example.

Question: What type of homes were built in the Neolithic era?
Ans: mud brick houses


Here is a question about this article: By the time of the Uruk period (c. 4100–2900 BC calibrated), the volume of trade goods transported along the canals and rivers of southern Mesopotamia facilitated the rise of many large, stratified, temple-centered cities (with populations of over 10,000 people) where centralized administrations employed specialized workers. It is fairly certain that it was during the Uruk period that Sumerian cities began to make use of slave labor captured from the hill country, and there is ample evidence for captured slaves as workers in the earliest texts. Artifacts, and even colonies of this Uruk civilization have been found over a wide area—from the Taurus Mountains in Turkey, to the Mediterranean Sea in the west, and as far east as central Iran.
What is the answer to this question: How many people lived in the cities?
****
So... over 10,000


Article: This period is generally taken to coincide with a major shift in population from southern Mesopotamia toward the north. Ecologically, the agricultural productivity of the Sumerian lands was being compromised as a result of rising salinity. Soil salinity in this region had been long recognized as a major problem. Poorly drained irrigated soils, in an arid climate with high levels of evaporation, led to the buildup of dissolved salts in the soil, eventually reducing agricultural yields severely. During the Akkadian and Ur III phases, there was a shift from the cultivation of wheat to the more salt-tolerant barley, but this was insufficient, and during the period from 2100 BC to 1700 BC, it is estimated that the population in this area declined by nearly three fifths. This greatly upset the balance of power within the region, weakening the areas where Sumerian was spoken, and comparatively strengthening those where Akkadian was the major language. Henceforth Sumerian would remain only a literary and liturgical language, similar to the position occupied by Latin in medieval Europe.

Question: The salinity of what in the region was long recognized as a major problem?
Ans:
Soil
