On February 14, 2009, The Walt Disney Company debuted "The American Idol Experience" at its Disney's Hollywood Studios theme park at the Walt Disney World Resort in Florida. In this live production, co-produced by 19 Entertainment, park guests chose from a list of songs and auditioned privately for Disney cast members. Those selected then performed on a stage in a 1000-seat theater replicating the Idol set. Three judges, whose mannerisms and style mimicked those of the real Idol judges, critiqued the performances. Audience members then voted for their favorite performer. There were several preliminary-round shows during the day that culminated in a "finals" show in the evening where one of the winners of the previous rounds that day was selected as the overall winner. The winner of the finals show received a "Dream Ticket" that granted them front-of-the-line privileges at any future American Idol audition. The attraction closed on August 30, 2014.

In what year did The Walt Disney Company open The American Idol Experience? 
Answer: 2009

Although the ECB is governed by European law directly and thus not by corporate law applying to private law companies, its set-up resembles that of a corporation in the sense that the ECB has shareholders and stock capital. Its capital is five billion euros which is held by the national central banks of the member states as shareholders. The initial capital allocation key was determined in 1998 on the basis of the states' population and GDP, but the key is adjustable. Shares in the ECB are not transferable and cannot be used as collateral.
What determined the ECB's initial capital?
the basis of the states' population and GDP


Input: On the Origin of Species
Interest in Darwin's writings continues, and scholars have generated an extensive literature, the Darwin Industry, about his life and work. The text of Origin itself has been subject to much analysis including a variorum, detailing the changes made in every edition, first published in 1959, and a concordance, an exhaustive external index published in 1981. Worldwide commemorations of the 150th anniversary of the publication of On the Origin of Species and the bicentenary of Darwin's birth were scheduled for 2009. They celebrated the ideas which "over the last 150 years have revolutionised our understanding of nature and our place within it".

What has been created in 1959 and filled with information about changes in every edition of On the Origin of Species?
Output: a variorum
