Input: Read this: In almost all federations the central government enjoys the powers of foreign policy and national defense as exclusive federal powers. Were this not the case a federation would not be a single sovereign state, per the UN definition. Notably, the states of Germany retain the right to act on their own behalf at an international level, a condition originally granted in exchange for the Kingdom of Bavaria's agreement to join the German Empire in 1871. Beyond this the precise division of power varies from one nation to another. The constitutions of Germany and the United States provide that all powers not specifically granted to the federal government are retained by the states. The Constitution of some countries like Canada and India, on the other hand, state that powers not explicitly granted to the provincial governments are retained by the federal government. Much like the US system, the Australian Constitution allocates to the Federal government (the Commonwealth of Australia) the power to make laws about certain specified matters which were considered too difficult for the States to manage, so that the States retain all other areas of responsibility. Under the division of powers of the European Union in the Lisbon Treaty, powers which are not either exclusively of European competence or shared between EU and state as concurrent powers are retained by the constituent states.
Question: What is the German Empire?

Output: Germany retain the right to act on their own behalf at an international level,

Input: Read this: The word ale comes from Old English ealu (plural ealo), in turn from Proto-Germanic *alu (plural *alu), ultimately from the Proto-Indo-European base *helut-, which holds connotations of "sorcery, magic, possession, intoxication". The word beer comes from Old English beor, from Proto-Germanic *beuza, probably from Proto-Indo-European *beusom, originally "brewer's yeast, beer dregs", although other theories have been provided connecting the word with Old English beow, "barley", or Latin bibere, "to drink". On the currency of two words for the same thing in the Germanic languages, the 12th-century Old Icelandic poem Alvissmal says, "Ale it is called among men, but among the gods, beer."
Question: What 12th century poet once wrote "Ale it is called among men, but among the gods, beer."?

Output: Alvissmal

Input: Read this: In response to a given problem situation (), a number of competing conjectures, or tentative theories (), are systematically subjected to the most rigorous attempts at falsification possible. This process, error elimination (), performs a similar function for science that natural selection performs for biological evolution. Theories that better survive the process of refutation are not more true, but rather, more "fit"in other words, more applicable to the problem situation at hand (). Consequently, just as a species' biological fitness does not ensure continued survival, neither does rigorous testing protect a scientific theory from refutation in the future. Yet, as it appears that the engine of biological evolution has, over many generations, produced adaptive traits equipped to deal with more and more complex problems of survival, likewise, the evolution of theories through the scientific method may, in Popper's view, reflect a certain type of progress: toward more and more interesting problems (). For Popper, it is in the interplay between the tentative theories (conjectures) and error elimination (refutation) that scientific knowledge advances toward greater and greater problems; in a process very much akin to the interplay between genetic variation and natural selection.
Question: What serves a different purpose in biological evolution than error elimination serves in science?

Output: unanswerable

Input: Read this: Remodelling of the structure began in 1762. After his accession to the throne in 1820, King George IV continued the renovation with the idea in mind of a small, comfortable home. While the work was in progress, in 1826, the King decided to modify the house into a palace with the help of his architect John Nash. Some furnishings were transferred from Carlton House, and others had been bought in France after the French Revolution. The external facade was designed keeping in mind the French neo-classical influence preferred by George IV. The cost of the renovations grew dramatically, and by 1829 the extravagance of Nash's designs resulted in his removal as architect. On the death of George IV in 1830, his younger brother King William IV hired Edward Blore to finish the work. At one stage, William considered converting the palace into the new Houses of Parliament, after the destruction of the Palace of Westminster by fire in 1834.
Question: What did King George IV originally want the structure to be?

Output:
a small, comfortable home
