Input: Read this: In the medieval period the wall circuit was expanded. Via Vittorio Emanuele continued to be the main road east-west through the walled city. West gate was still Porta Nuova, the circuit continued to Corso Alberti, to Piazza Vittorio Emanuele Orlando where it turned east along Via Volturno to Piazza Verdi and along the line of Via Cavour. At this north-east corner there was a defence, Castello a Mare, to protect the port at La Cala. A huge chain was used to block La Cala with the other end at S Maria della Catena (St Mary of the Chain). The sea-side wall was along the western side of Foro Italico Umberto. The wall turns west along the northern side of Via Abramo Lincoln, continues along Corso Tukory. The wall turns north approximately on Via Benedetto, to Palazzo dei Normanni and back to Porta Nuova.

Question: During which historical period was the wall circuit expanded?

Output: medieval

QUES: The population of Paris in its administrative city limits was 2,241,346 in January 2014. This makes Paris the fifth largest municipality in the European Union, following London, Berlin, Madrid and Rome. Eurostat, the statistical agency of the EU, places Paris (6.5 million people) second behind London (8 million) and ahead of Berlin (3.5 million), based on the 2012 populations of what Eurostat calls "urban audit core cities". The Paris Urban Area, or "unite urbaine", is a statistical area created by the French statistical agency INSEE to measure the population of built-up areas around the city. It is slightly smaller than the Paris Region. According to INSEE, the Paris Urban Area had a population of 10,550,350 at the January 2012 census, the most populous in the European Union, and third most populous in Europe, behind Istanbul and Moscow. The Paris Metropolitan Area is the second most populous in the European Union after London with a population of 12,341,418 at the Jan. 2012 census.

What 4 cities are larger than Paris in the EU?
What is the answer?
ANS: London, Berlin, Madrid and Rome

QUES: Many hunter-gatherers consciously manipulate the landscape through cutting or burning undesirable plants while encouraging desirable ones, some even going to the extent of slash-and-burn to create habitat for game animals. These activities are on an entirely different scale to those associated with agriculture, but they are nevertheless domestication on some level. Today, almost all hunter-gatherers depend to some extent upon domesticated food sources either produced part-time or traded for products acquired in the wild.
None of the modern hunter-gatherers depend of which kind of food sources?

ANS: unanswerable

Average attendance for AFL games were around 10,00011,000 per game in the 1990s, though during the recession connected to the dot-com bubble and the September 11, 2001 attacks average attendance dropped below 10,000 for several years. From the start of the 2004 season until the final season of the original league in 2008, average attendance was above 12,000, with 12,392 in 2007. Eleven of the seventeen teams in operation in 2007 had average attendance figures over 13,000. In 2008, the overall attendance average increased to 12,957, with eight teams exceeding 13,000 per game.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the normal per game attendance of AFL games in the 1990s?
Ah, so.. 10,00011,000

Question: Natural phonology is a theory based on the publications of its proponent David Stampe in 1969 and (more explicitly) in 1979. In this view, phonology is based on a set of universal phonological processes that interact with one another; which ones are active and which are suppressed is language-specific. Rather than acting on segments, phonological processes act on distinctive features within prosodic groups. Prosodic groups can be as small as a part of a syllable or as large as an entire utterance. Phonological processes are unordered with respect to each other and apply simultaneously (though the output of one process may be the input to another). The second most prominent natural phonologist is Patricia Donegan (Stampe's wife); there are many natural phonologists in Europe, and a few in the U.S., such as Geoffrey Nathan. The principles of natural phonology were extended to morphology by Wolfgang U. Dressler, who founded natural morphology.
Try to answer this question if possible: Aside from being active what other condition can the universal phonological processes exist in?
Answer: suppressed

Question: Annelids with blood vessels use metanephridia to remove soluble waste products, while those without use protonephridia. Both of these systems use a two-stage filtration process, in which fluid and waste products are first extracted and these are filtered again to re-absorb any re-usable materials while dumping toxic and spent materials as urine. The difference is that protonephridia combine both filtration stages in the same organ, while metanephridia perform only the second filtration and rely on other mechanisms for the first in annelids special filter cells in the walls of the blood vessels let fluids and other small molecules pass into the coelomic fluid, where it circulates to the metanephridia. In annelids the points at which fluid enters the protonephridia or metanephridia are on the forward side of a septum while the second-stage filter and the nephridiopore (exit opening in the body wall) are in the following segment. As a result, the hindmost segment (before the growth zone and pygidium) has no structure that extracts its wastes, as there is no following segment to filter and discharge them, while the first segment contains an extraction structure that passes wastes to the second, but does not contain the structures that re-filter and discharge urine.
Try to answer this question if possible: What do metanephridia produce?
