Input: Read this: The Allied disaster at Austerlitz significantly shook the faith of Emperor Francis in the British-led war effort. France and Austria agreed to an armistice immediately and the Treaty of Pressburg followed shortly after on 26 December. Pressburg took Austria out of both the war and the Coalition while reinforcing the earlier treaties of Campo Formio and of Lunéville between the two powers. The treaty confirmed the Austrian loss of lands to France in Italy and Bavaria, and lands in Germany to Napoleon's German allies. It also imposed an indemnity of 40 million francs on the defeated Habsburgs and allowed the fleeing Russian troops free passage through hostile territories and back to their home soil. Napoleon went on to say, "The battle of Austerlitz is the finest of all I have fought." Frank McLynn suggests that Napoleon was so successful at Austerlitz that he lost touch with reality, and what used to be French foreign policy became a "personal Napoleonic one". Vincent Cronin disagrees, stating that Napoleon was not overly ambitious for himself, "he embodied the ambitions of thirty million Frenchmen".
Question: What was the name of the treaty signed by France and Austria on 26 December?

Output: the Treaty of Pressburg


Input: Read this: The internal classification of this group has undergone considerable revision. The Cronquist system, proposed by Arthur Cronquist in 1968 and published in its full form in 1981, is still widely used but is no longer believed to accurately reflect phylogeny. A consensus about how the flowering plants should be arranged has recently begun to emerge through the work of the Angiosperm Phylogeny Group (APG), which published an influential reclassification of the angiosperms in 1998. Updates incorporating more recent research were published as APG II in 2003 and as APG III in 2009.
Question: What internal component has undergone considerable revision?

Output: classification


Input: Read this: The British Royal Navy is constructing two new larger STOVL aircraft carriers, the Queen Elizabeth class, to replace the three Invincible-class carriers.
