Input: Read this: From September 1823 to 1826 Chopin attended the Warsaw Lyceum, where he received organ lessons from the Czech musician Wilhelm Wurfel during his first year. In the autumn of 1826 he began a three-year course under the Silesian composer Jozef Elsner at the Warsaw Conservatory, studying music theory, figured bass and composition.[n 3] Throughout this period he continued to compose and to give recitals in concerts and salons in Warsaw. He was engaged by the inventors of a mechanical organ, the "eolomelodicon", and on this instrument in May 1825 he performed his own improvisation and part of a concerto by Moscheles. The success of this concert led to an invitation to give a similar recital on the instrument before Tsar Alexander I, who was visiting Warsaw; the Tsar presented him with a diamond ring. At a subsequent eolomelodicon concert on 10 June 1825, Chopin performed his Rondo Op. 1. This was the first of his works to be commercially published and earned him his first mention in the foreign press, when the Leipzig Allgemeine Musikalische Zeitung praised his "wealth of musical ideas".
Question: Which tsar did Frederic perform for due to his success in previous concerts?

Output: Alexander I

QUES: Von Neumann introduced the study of rings of operators, through the von Neumann algebras. A von Neumann algebra is a *-algebra of bounded operators on a Hilbert space that is closed in the weak operator topology and contains the identity operator. The von Neumann bicommutant theorem shows that the analytic definition is equivalent to a purely algebraic definition as an algebra of symmetries. The direct integral was introduced in 1949 by John von Neumann. One of von Neumann's analyses was to reduce the classification of von Neumann algebras on separable Hilbert spaces to the classification of factors.
What is von Neumann algebra?

ANS: algebra of bounded operators on a Hilbert space that is closed in the weak operator topology and contains the identity operator

Contestants go through at least three sets of cuts. The first is a brief audition with a few other contestants in front of selectors which may include one of the show's producers. Although auditions can exceed 10,000 in each city, only a few hundred of these make it past the preliminary round of auditions. Successful contestants then sing in front of producers, where more may be cut. Only then can they proceed to audition in front of the judges, which is the only audition stage shown on television. Those selected by the judges are sent to Hollywood. Between 1060 people in each city may make it to Hollywood[citation needed].
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many rounds can a contestant make it through before Hollywood?
Ah, so.. three

Question: The announcement came two years after Dell Inc. returned to private ownership, claiming that it faced bleak prospects and would need several years out of the public eye to rebuild its business. It's thought that the company's value has roughly doubled since then. EMC was being pressured by Elliott Management, a hedge fund holding 2.2% of EMC's stock, to reorganize their unusual "Federation" structure, in which EMC's divisions were effectively being run as independent companies. Elliott argued this structure deeply undervalued EMC's core "EMC II" data storage business, and that increasing competition between EMC II and VMware products was confusing the market and hindering both companies. The Wall Street Journal estimated that in 2014 Dell had revenue of $27.3 billion from personal computers and $8.9bn from servers, while EMC had $16.5bn from EMC II, $1bn from RSA Security, $6bn from VMware, and $230 million from Pivotal Software. EMC owns around 80 percent of the stock of VMware. The proposed acquisition will maintain VMware as a separate company, held via a new tracking stock, while the other parts of EMC will be rolled into Dell. Once the acquisition closes Dell will again publish quarterly financial results, having ceased these on going private in 2013.
Try to answer this question if possible: What hedge fund group was pressuring MEC into restructuring?
Answer: unanswerable

Problem: Despite plans of expanding into other global regions and product segments, Dell was heavily dependent on U.S. corporate PC market, as desktop PCs sold to both commercial and corporate customers accounted for 32 percent of its revenue, 85 percent of its revenue comes from businesses, and Sixty-four percent of its revenue comes from North and South America, according to its 2006 third-quarter results. U.S. shipments of desktop PCs were shrinking, and the corporate PC market which purchases PCs in upgrade cycles had largely decided to take a break from buying new systems. The last cycle started around 2002, three or so years after companies started buying PCs ahead of the perceived Y2K problems, and corporate clients were not expected to upgrade again until extensive testing of Microsoft's Windows Vista (expected in early 2007), putting the next upgrade cycle around 2008. Heavily depending on PCs, Dell had to slash prices to boost sales volumes, while demanding deep cuts from suppliers.
What year were Dell's PC profits shrinking?
---
Answer:
2006
