Input: Glass
The observation that old windows are sometimes found to be thicker at the bottom than at the top is often offered as supporting evidence for the view that glass flows over a timescale of centuries, the assumption being that the glass has exhibited the liquid property of flowing from one shape to another. This assumption is incorrect, as once solidified, glass stops flowing. The reason for the observation is that in the past, when panes of glass were commonly made by glassblowers, the technique used was to spin molten glass so as to create a round, mostly flat and even plate (the crown glass process, described above). This plate was then cut to fit a window. The pieces were not absolutely flat; the edges of the disk became a different thickness as the glass spun. When installed in a window frame, the glass would be placed with the thicker side down both for the sake of stability and to prevent water accumulating in the lead cames at the bottom of the window. Occasionally such glass has been found installed with the thicker side at the top, left or right.

What was the benefit of installing glass with the thick side at the bottom, in addition to avoiding water accumulation?
Output: stability

Input: Classical music
Given the wide range of styles in classical music, from Medieval plainchant sung by monks to Classical and Romantic symphonies for orchestra from the 1700s and 1800s to avant-garde atonal compositions for solo piano from the 1900s, it is difficult to list characteristics that can be attributed to all works of that type. However, there are characteristics that classical music contains that few or no other genres of music contain, such as the use of a printed score and the performance of very complex instrumental works (e.g., the fugue). As well, although the symphony did not exist through the entire classical music period, from the mid-1700s to the 2000s the symphony ensembleand the works written for ithave become a defining feature of classical music.

Who sang Medieval plainchant?
Output: monks

Input: The Sun (United Kingdom)
During the campaign for the United Kingdom general election, 2010, The Independent ran ads declaring that "Rupert Murdoch won't decide this election you will." In response James Murdoch and Rebekah Wade "appeared unannounced and uninvited on the editorial floor" of the Independent, and had an energetic conversation with its editor Simon Kelner. Several days later the Independent reported The Sun's failure to report its own YouGov poll result which said that "if people thought Mr Clegg's party had a significant chance of winning the election" the Liberal Democrats would win 49% of the vote, and with it a landslide majority.

Who showed up on the editorial floor of the Independent?
Output: James Murdoch and Rebekah Wade

Input: Edmund Burke
Burke supported the war against revolutionary France, seeing Britain as fighting on the side of the royalists and emigres in a civil war, rather than fighting against the whole nation of France. Burke also supported the royalist uprising in La Vendee, describing it on 4 November 1793 in a letter to William Windham, as "the sole affair I have much heart in". Burke wrote to Henry Dundas on 7 October urging him to send reinforcements there, as he viewed it as the only theatre in the war that might lead to a march on Paris. Dundas did not follow Burke's advice, however.

Which faction's uprising in La Vendee did Burke support?
Output:
royalist
