Input: Read this: The hydraulic crane was invented by Sir William Armstrong in 1846, primarily for use at the Tyneside docks for loading cargo. These quickly supplanted the earlier steam driven elevators: exploiting Pascal's law, they provided a much greater force. A water pump supplied a variable level of water pressure to a plunger encased inside a vertical cylinder, allowing the level of the platform (carrying a heavy load) to be raised and lowered. Counterweights and balances were also used to increase the lifting power of the apparatus.
Question: Who invented the hydraulic crane in 1846?

Output: Sir William Armstrong

Input: Read this: 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: What shifted from the north to the south of Mesopotamia?

Output: unanswerable

Input: Read this: In some countries anti-Masonry is often related to antisemitism and anti-Zionism. For example, In 1980, the Iraqi legal and penal code was changed by Saddam Hussein's ruling Ba'ath Party, making it a felony to "promote or acclaim Zionist principles, including Freemasonry, or who associate [themselves] with Zionist organisations". Professor Andrew Prescott of the University of Sheffield writes: "Since at least the time of the Protocols of the Elders of Zion, antisemitism has gone hand in hand with anti-masonry, so it is not surprising that allegations that 11 September was a Zionist plot have been accompanied by suggestions that the attacks were inspired by a masonic world order".
Question: According to Professor Andrew Prescott, how long has antisemitism gone together with anti-masonry?

Output: Since at least the time of the Protocols of the Elders of Zion

Input: Read this: Genome-wide association studies have found 27 genetic variants that are associated with an increased risk of myocardial infarction. Strongest association of MI has been found with the 9p21 genomic locus, which contains genes CDKN2A & 2B, although the single nucleotide polymorphisms that are implicated are within a non-coding region. The majority of these variants are in regions that have not been previously implicated in coronary artery disease. The following genes have an association with MI: PCSK9, SORT1, MIA3, WDR12, MRAS, PHACTR1, LPA, TCF21, MTHFDSL, ZC3HC1, CDKN2A, 2B, ABO, PDGF0, APOA5, MNF1ASM283, COL4A1, HHIPC1, SMAD3, ADAMTS7, RAS1, SMG6, SNF8, LDLR, SLC5A3, MRPS6, KCNE2.
Question: How many genetic variants are shown to decrease risk of an MI?

Output:
unanswerable
