Question: Read this and answer the question

The first telephone lines were installed in 1882 and electric street lights took the place of the gas operated ones in 1886. The Hipódromo de Maroñas started operating in 1888, and the neighbourhoods of Reus del Sur, Reus del Norte and Conciliación were inaugurated in 1889. The new building of the School of Arts and Trades, as well as Zabala Square in Ciudad Vieja were inaugurated in 1890, followed by the Italian Hospital in 1891. In the same year, the village of Peñarol was founded. Other neighbourhoods that were founded were Belgrano and Belvedere in 1892, Jacinto Vera in 1895 and Trouville in 1897. In 1894 the new port was constructed, and in 1897, the Central Railway Station of Montevideo was inaugurated.

When did electric street lights replace the gas operated lights?
Answer: 1886


Problem: Solar chemical processes use solar energy to drive chemical reactions. These processes offset energy that would otherwise come from a fossil fuel source and can also convert solar energy into storable and transportable fuels. Solar induced chemical reactions can be divided into thermochemical or photochemical. A variety of fuels can be produced by artificial photosynthesis. The multielectron catalytic chemistry involved in making carbon-based fuels (such as methanol) from reduction of carbon dioxide is challenging; a feasible alternative is hydrogen production from protons, though use of water as the source of electrons (as plants do) requires mastering the multielectron oxidation of two water molecules to molecular oxygen. Some have envisaged working solar fuel plants in coastal metropolitan areas by 2050 –  the splitting of sea water providing hydrogen to be run through adjacent fuel-cell electric power plants and the pure water by-product going directly into the municipal water system. Another vision involves all human structures covering the earth's surface (i.e., roads, vehicles and buildings) doing photosynthesis more efficiently than plants.
What process converts solar energy into storable and transportable fuels?
The answer is the following: Solar chemical processes


The National Disaster Relief Commission initiated a "Level II emergency contingency plan", which covers the most serious class of natural disasters. The plan rose to Level I at 22:15 CST, May 12.
What class of disasters is a level II emergency?
most serious


Input: New York City
Sociologists and criminologists have not reached consensus on the explanation for the dramatic decrease in the city's crime rate. Some attribute the phenomenon to new tactics used by the NYPD, including its use of CompStat and the broken windows theory. Others cite the end of the crack epidemic and demographic changes, including from immigration. Another theory is that widespread exposure to lead pollution from automobile exhaust, which can lower intelligence and increase aggression levels, incited the initial crime wave in the mid-20th century, most acutely affecting heavily trafficked cities like New York. A strong correlation was found demonstrating that violent crime rates in New York and other big cities began to fall after lead was removed from American gasoline in the 1970s. Another theory cited to explain New York City's falling homicide rate is the inverse correlation between the number of murders and the increasingly wetter climate in the city.

The decrease in crime in New York is sometimes attributed to the decline of what street drug?
Output: crack


Input: Article: In Northern Germany, Netherlands, northern Poland, Denmark, and the Baltic countries local building stone was unavailable but there was a strong tradition of building in brick. The resultant style, Brick Gothic, is called "Backsteingotik" in Germany and Scandinavia and is associated with the Hanseatic League. In Italy, stone was used for fortifications, but brick was preferred for other buildings. Because of the extensive and varied deposits of marble, many buildings were faced in marble, or were left with undecorated façade so that this might be achieved at a later date.

Now answer this question: With what type of facade were buildings left with if they were to completed at a later time?

Output: undecorated façade


Problem: The main industries are mineral based, agriculture based, and textile based. Rajasthan is the second largest producer of polyester fibre in India. The Pali and Bhilwara District produces more cloth than Bhiwandi, Maharashtra and the bhilwara is the largest city in suitings production and export and Pali is largest city in cotton and polyster in blouse pieces and rubia production and export. Several prominent chemical and engineering companies are located in the city of Kota, in southern Rajasthan. Rajasthan is pre-eminent in quarrying and mining in India. The Taj Mahal was built from the white marble which was mined from a town called Makrana. The state is the second largest source of cement in India. It has rich salt deposits at Sambhar, copper mines at Khetri, Jhunjhunu, and zinc mines at Dariba, Zawar mines and Rampura Aghucha (opencast) near Bhilwara. Dimensional stone mining is also undertaken in Rajasthan. Jodhpur sandstone is mostly used in monuments, important buildings and residential buildings. This stone is termed as "chittar patthar". Jodhpur leads in Handicraft and Guar Gum industry. Rajasthan is also a part of the Mumbai-Delhi Industrial corridor is set to benefit economically. The State gets 39% of the DMIC, with major districts of Jaipur, Alwar, Kota and Bhilwara benefiting.
What is the largest city for polyster blouse pieces in Rajasthan?
The answer is the following:
Pali is largest city in cotton and polyster in blouse pieces
