Problem: Given the question: Question: "How is the ranking of parks determined?" Context: "In its 2013 ParkScore ranking, The Trust for Public Land reported that the park system in New York City was the second best park system among the 50 most populous U.S. cities, behind the park system of Minneapolis. ParkScore ranks urban park systems by a formula that analyzes median park size, park acres as percent of city area, the percent of city residents within a half-mile of a park, spending of park services per resident, and the number of playgrounds per 10,000 residents." Answer:

input question: Question: "What was done in the 16th century?" Context: "On 3 May 1505 King Alexander I Jagiellon granted the Act of "Nihil novi nisi commune consensu" (Latin: "I accept nothing new except by common consent"). This forbade the king to pass any new law without the consent of the representatives of the nobility, in Sejm and Senat assembled, and thus greatly strengthened the nobility's political position. Basically, this act transferred legislative power from the king to the Sejm. This date commonly marks the beginning of the First Rzeczpospolita, the period of a szlachta-run "Commonwealth"." Answer:???

Q: Question: "What change was brought about?" Context: "Several MLB teams used to play regular exhibition games during the year against nearby teams in the other major league, but regular-season interleague play has made such games unnecessary. The two Canadian MLB teams, the Toronto Blue Jays of the American League and the Montreal Expos of the National League, met annually to play the Pearson Cup exhibition game; this tradition ended when the Expos moved to Washington DC for the 2005 season. Similarly, the New York Yankees played in the Mayor's Trophy Game against various local rivals from 1946 to 1983." Answer:
A: this tradition ended when the Expos moved to Washington DC for the 2005 season

Question: Question: "What are matrix groups for any constant c?" Context: "for any constant c. Matrix groups over these fields fall under this regime, as do adele rings and adelic algebraic groups, which are basic to number theory. Galois groups of infinite field extensions such as the absolute Galois group can also be equipped with a topology, the so-called Krull topology, which in turn is central to generalize the above sketched connection of fields and groups to infinite field extensions. An advanced generalization of this idea, adapted to the needs of algebraic geometry, is the etale fundamental group." Answer:
Answer: number theory

Please answer this: Question: "what is the last word in the passage?" Context: "Both private individuals and large production companies have used YouTube to grow audiences. Independent content creators have built grassroots followings numbering in the thousands at very little cost or effort, while mass retail and radio promotion proved problematic. Concurrently, old media celebrities moved into the website at the invitation of a YouTube management that witnessed early content creators accruing substantial followings, and perceived audience sizes potentially larger than that attainable by television. While YouTube's revenue-sharing "Partner Program" made it possible to earn a substantial living as a video producerits top five hundred partners each earning more than $100,000 annually and its ten highest-earning channels grossing from $2.5 million to $12 millionin 2012 CMU business editor characterized YouTube as "a free-to-use... promotional platform for the music labels". In 2013 Forbes' Katheryn Thayer asserted that digital-era artists' work must not only be of high quality, but must elicit reactions on the YouTube platform and social media. In 2013, videos of the 2.5% of artists categorized as "mega", "mainstream" and "mid-sized" received 90.3% of the relevant views on YouTube and Vevo. By early 2013 Billboard had announced that it was factoring YouTube streaming data into calculation of the Billboard Hot 100 and related genre charts." Answer:
