Input: Read this: In May 1985, Gorbachev delivered a speech in Leningrad advocating reforms and an anti-alcohol campaign to tackle widespread alcoholism. Prices on vodka, wine, and beer were raised in order to make these drinks more expensive and a disincentive to consumers, and the introduction of rationing. Unlike most forms of rationing intended to conserve scarce goods, this was done to restrict sales with the overt goal of curtailing drunkenness. Gorbachev's plan also included billboards promoting sobriety, increased penalties for public drunkenness, and to censor drinking scenes from old movies. Although this program was not a direct copycat of Tsar Nicholas II's outright prohibition during World War I, Gorbachev faced the same adverse economic reaction as did the last Tsar. The disincentivization of alcohol consumption was a serious blow to the state budget according to Alexander Yakovlev, who noted annual collections of alcohol taxes decreased by 100 billion rubles. Alcohol production migrated to the black market, or through moonshining as some made "bathtub vodka" with homegrown potatoes. Poorer, less educated Russians resorted to drinking unhealthy substitutes such as nail polish, rubbing alcohol or men's cologne, which only served to be an additional burden on Russia's healthcare sector due to the subsequent poisoning cases. The purpose of these reforms, however, was to prop up the existing centrally planned economy, unlike later reforms, which tended toward market socialism.
Question: Other than increasing pricing what was another measure that was introduced to decrease alcohol consumption?

Output: rationing

QUES: In the last two decades, photovoltaics (PV), also known as solar PV, has evolved from a pure niche market of small scale applications towards becoming a mainstream electricity source. A solar cell is a device that converts light directly into electricity using the photoelectric effect. The first solar cell was constructed by Charles Fritts in the 1880s. In 1931 a German engineer, Dr Bruno Lange, developed a photo cell using silver selenide in place of copper oxide. Although the prototype selenium cells converted less than 1% of incident light into electricity, both Ernst Werner von Siemens and James Clerk Maxwell recognized the importance of this discovery. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the crystalline silicon solar cell in 1954. These early solar cells cost 286 USD/watt and reached efficiencies of 4.56%. By 2012 available efficiencies exceed 20% and the maximum efficiency of research photovoltaics is over 40%.

Who created the first solar cell?
What is the answer?
ANS: Charles Fritts

QUES: The River Test runs along the western border of the city, separating it from the New Forest. There are bridges over the Test from Southampton, including the road and rail bridges at Redbridge in the south and the M27 motorway to the north. The River Itchen runs through the middle of the city and is bridged in several places. The northernmost bridge, and the first to be built, is at Mansbridge, where the A27 road crosses the Itchen. The original bridge is closed to road traffic, but is still standing and open to pedestrians and cyclists. The river is bridged again at Swaythling, where Woodmill Bridge separates the tidal and non tidal sections of the river. Further south is Cobden Bridge which is notable as it was opened as a free bridge (it was originally named the Cobden Free Bridge), and was never a toll bridge. Downstream of the Cobden Bridge is the Northam Railway Bridge, then the Northam Road Bridge, which was the first major pre-stressed concrete bridge to be constructed in the United Kingdom. The southernmost, and newest, bridge on the Itchen is the Itchen Bridge, which is a toll bridge.
Where was the first bridge built across the River Itchen?

ANS: Mansbridge

Spielberg's films often deal with several recurring themes. Most of his films deal with ordinary characters searching for or coming in contact with extraordinary beings or finding themselves in extraordinary circumstances. In an AFI interview in August 2000 Spielberg commented on his interest in the possibility of extra terrestrial life and how it has influenced some of his films. Spielberg described himself as feeling like an alien during childhood, and his interest came from his father, a science fiction fan, and his opinion that aliens would not travel light years for conquest, but instead curiosity and sharing of knowledge.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When in his life did Spielberg 'feel like an alien'?
Ah, so.. during childhood

Question: Kerry and his second wife, Mozambican-born businesswoman and philanthropist Maria Teresa Thierstein Simoes Ferreira (known as Teresa), the widow of Kerry's late Pennsylvania Republican Senate colleague Henry John Heinz III, were introduced to each other by Heinz at an Earth Day rally in 1990. Early the following year, Senator Heinz was killed in a plane crash near Lower Merion. Teresa has three sons from her previous marriage to Heinz, Henry John Heinz IV, Andre Thierstein Heinz, and Christopher Drake Heinz. Heinz and Kerry were married on May 26, 1995, in Nantucket, Massachusetts.
Try to answer this question if possible: Who was Kerry's 2nd wife's previous husband?
Answer: Henry John Heinz III

Input: Read this: The inventor Nicephore Niepce produced the first permanent photograph on a polished pewter plate in Paris in 1825, and then developed the process with Louis Daguerre. The work of Etienne-Jules Marey in the 1880s contributed considerably to the development of modern photography. Photography came to occupy a central role in Parisian Surrealist activity, in the works of Man Ray and Maurice Tabard. Numerous photographers achieved renown for their photography of Paris, including Eugene Atget, noted for his depictions of street scenes, Robert Doisneau, noted for his playful pictures of people and market scenes (among which Le baiser de l'hotel de ville has became iconic of the romantic vision of Paris), Marcel Bovis, noted for his night scenes, and others such as Jacques-Henri Lartigue and Cartier-Bresson. Poster art also became an important art form in Paris in the late nineteenth century, through the work of Henri de Toulouse-Lautrec, Jules Cheret, Eugene Grasset, Adolphe Willette, Pierre Bonnard, Georges de Feure, Henri-Gabriel Ibels, Gavarni, and Alphonse Mucha.
Question: In what year was the first permanent photograph produced?

Output:
1825
