[Q]: I know that the answer to the question "What was the original area code for the whole geographic area?" is in "Southeastern Pennsylvania was assigned the 215 area code in 1947 when the North American Numbering Plan of the "Bell System" went into effect. The geographic area covered by the code was split nearly in half in 1994 when area code 610 was created, with the city and its northern suburbs retaining 215. Overlay area code 267 was added to the 215 service area in 1997, and 484 was added to the 610 area in 1999. A plan in 2001 to introduce a third overlay code to both service areas (area code 445 to 215, area code 835 to 610) was delayed and later rescinded.". Can you tell me what it is?

input: Please answer the following: I know that the answer to the question "When will people be able to eat well once more?" is in "Traditionally a carnival feast was the last opportunity to eat well before the time of food shortage at the end of the winter during which one was limited to the minimum necessary. On what nowadays is called vastenavond (the days before fasting) all the remaining winter stores of lard, butter and meat which were left would be eaten, for it would soon start to rot and decay. The selected livestock had in fact already been slaughtered in November and the meat would be no longer preservable. All the food that had survived the winter had to be eaten to assure that everyone was fed enough to survive until the coming spring would provide new food sources.". Can you tell me what it is?

Please answer this: I know that the answer to the question "The European Union is not a federal state but a?" is in "Until recently, in the absence of prior agreement on a clear and precise definition, the concept was thought to mean (as a shorthand) 'a division of sovereignty between two levels of government'. New research, however, argues that this cannot be correct, as dividing sovereignty - when this concept is properly understood in its core meaning of the final and absolute source of political authority in a political community - is not possible. The descent of the United States into Civil War in the mid-nineteenth century, over disputes about unallocated competences concerning slavery and ultimately the right of secession, showed this. One or other level of government could be sovereign to decide such matters, but not both simultaneously. Therefore, it is now suggested that federalism is more appropriately conceived as 'a division of the powers flowing from sovereignty between two levels of government'. What differentiates the concept from other multi-level political forms is the characteristic of equality of standing between the two levels of government established. This clarified definition opens the way to identifying two distinct federal forms, where before only one was known, based upon whether sovereignty resides in the whole (in one people) or in the parts (in many peoples): the federal state (or federation) and the federal union of states (or federal union), respectively. Leading examples of the federal state include the United States, Germany, Canada, Switzerland, Australia and India. The leading example of the federal union of states is the European Union.".

Problem: I know that the answer to the question "At what point did the Jewish population double?" is in "By the 1st century, Babylonia, to which Jews migrated to after the Babylonian conquest as well as after the Bar Kokhba revolt in 135 CE, already held a speedily growing population of an estimated 1,000,000 Jews, which increased to an estimated 2 million between the years 200 CE 500 CE, both by natural growth and by immigration of more Jews from the Land of Israel, making up about 1/6 of the world Jewish population at that era. At times conversion has accounted for a part of Jewish population growth. Some have claimed that in the 1st century of the Christian era, for example, the population more than doubled, from four to 810 million within the confines of the Roman Empire, in good part as a result of a wave of conversion.".

A: between the years 200 CE 500 CE

Problem: Given the question: I know that the answer to the question "Who is told to cry for the children?" is in "Luke's gospel also describes an interaction between Jesus and the women among the crowd of mourners following him, quoting Jesus as saying "Daughters of Jerusalem, do not weep for me, but weep for yourselves and for your children. For behold, the days are coming when they will say, 'Blessed are the barren and the wombs that never bore and the breasts that never nursed!' Then they will begin to say to the mountains, 'Fall on us,' and to the hills, 'Cover us.' For if they do these things when the wood is green, what will happen when it is dry?"[Lk. 23:28-31]".

Previously slaves had been traded by Arabs north to the northern part of Africa and into the Middle East.". Can you tell me what it is?
