Input: Read this: Ashkenazi Jews have a noted history of achievement in Western societies in the fields of exact and social sciences, literature, finance, politics, media, and others. In those societies where they have been free to enter any profession, they have a record of high occupational achievement, entering professions and fields of commerce where higher education is required. Ashkenazi Jews have won a large number of the Nobel awards. While they make up about 2% of the U.S. population, 27% of United States Nobel prize winners in the 20th century, a quarter of Fields Medal winners, 25% of ACM Turing Award winners, half the world's chess champions, including 8% of the top 100 world chess players, and a quarter of Westinghouse Science Talent Search winners have Ashkenazi Jewish ancestry.
Question: What percentage of Nobel award winners from the United States in the 20th century have been Ashkenazi Jews? 

Output: 27%


QUES: In the spring of 1834, Chopin attended the Lower Rhenish Music Festival in Aix-la-Chapelle with Hiller, and it was there that Chopin met Felix Mendelssohn. After the festival, the three visited Düsseldorf, where Mendelssohn had been appointed musical director. They spent what Mendelssohn described as "a very agreeable day", playing and discussing music at his piano, and met Friedrich Wilhelm Schadow, director of the Academy of Art, and some of his eminent pupils such as Lessing, Bendemann, Hildebrandt and Sohn. In 1835 Chopin went to Carlsbad, where he spent time with his parents; it was the last time he would see them. On his way back to Paris, he met old friends from Warsaw, the Wodzińskis. He had made the acquaintance of their daughter Maria in Poland five years earlier, when she was eleven. This meeting prompted him to stay for two weeks in Dresden, when he had previously intended to return to Paris via Leipzig. The sixteen-year-old girl's portrait of the composer is considered, along with Delacroix's, as among Chopin's best likenesses. In October he finally reached Leipzig, where he met Schumann, Clara Wieck and Felix Mendelssohn, who organised for him a performance of his own oratorio St. Paul, and who considered him "a perfect musician". In July 1836 Chopin travelled to Marienbad and Dresden to be with the Wodziński family, and in September he proposed to Maria, whose mother Countess Wodzińska approved in principle. Chopin went on to Leipzig, where he presented Schumann with his G minor Ballade. At the end of 1836 he sent Maria an album in which his sister Ludwika had inscribed seven of his songs, and his 1835 Nocturne in C-sharp minor, Op. 27, No. 1. The anodyne thanks he received from Maria proved to be the last letter he was to have from her.

Who did Chopin attend the Lower Rhenish Music Festival with?
What is the answer?
ANS: Hiller


QUES: Traditionally, subspecies are seen as geographically isolated and genetically differentiated populations. That is, "the designation 'subspecies' is used to indicate an objective degree of microevolutionary divergence" One objection to this idea is that it does not specify what degree of differentiation is required. Therefore, any population that is somewhat biologically different could be considered a subspecies, even to the level of a local population. As a result, Templeton has argued that it is necessary to impose a threshold on the level of difference that is required for a population to be designated a subspecies.
What is an objection to the idea of subspecies because it doesn't specify this?

ANS: degree of differentiation


In a new and effective tactic, the Popular Front launched a rail blockade of Armenia, which caused petrol and food shortages because 85 percent of Armenia's freight came from Azerbaijan. Under pressure from the Popular Front the Communist authorities in Azerbaijan started making concessions. On September 25, they passed a sovereignty law that gave precedence to Azerbaijani law, and on October 4, the Popular Front was permitted to register as a legal organization as long as it lifted the blockade. Transport communications between Azerbaijan and Armenia never fully recovered. Tensions continued to escalate and on December 29, Popular Front activists seized local party offices in Jalilabad, wounding dozens.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was the sovereignty law passed?
Ah, so.. September 25


Question: The machine was about a century ahead of its time. All the parts for his machine had to be made by hand — this was a major problem for a device with thousands of parts. Eventually, the project was dissolved with the decision of the British Government to cease funding. Babbage's failure to complete the analytical engine can be chiefly attributed to difficulties not only of politics and financing, but also to his desire to develop an increasingly sophisticated computer and to move ahead faster than anyone else could follow. Nevertheless, his son, Henry Babbage, completed a simplified version of the analytical engine's computing unit (the mill) in 1888. He gave a successful demonstration of its use in computing tables in 1906.
Try to answer this question if possible: When was the mill created by Henry Babbage?
Answer: 1888


QUES: Besides the city wall, other famous Ming-era structures in the city included the famous Ming Xiaoling Mausoleum and Porcelain Tower, although the latter was destroyed by the Taipings in the 19th century either in order to prevent a hostile faction from using it to observe and shell the city or from superstitious fear of its geomantic properties.
One possibility the Tower was destroyed was to prevent it's use by a hostile enemy. What is the other possibility?

ANS:
superstitious fear of its geomantic properties
