One hundred years after the fall of Constantinople in 1453, Pierre Belon described in his work Observations in 1553 that pissasphalto, a mixture of pitch and bitumen, was used in Dubrovnik for tarring of ships from where it was exported to a market place in Venice where it could be bought by anyone. An 1838 edition of Mechanics Magazine cites an early use of asphalt in France. A pamphlet dated 1621, by "a certain Monsieur d'Eyrinys, states that he had discovered the existence (of asphaltum) in large quantities in the vicinity of Neufchatel", and that he proposed to use it in a variety of ways "principally in the construction of air-proof granaries, and in protecting, by means of the arches, the water-courses in the city of Paris from the intrusion of dirt and filth", which at that time made the water unusable. "He expatiates also on the excellence of this material for forming level and durable terraces" in palaces, "the notion of forming such terraces in the streets not one likely to cross the brain of a Parisian of that generation". But it was generally neglected in France until the revolution of 1830. Then, in the 1830s, there was a surge of interest, and asphalt became widely used "for pavements, flat roofs, and the lining of cisterns, and in England, some use of it had been made of it for similar purposes". Its rise in Europe was "a sudden phenomenon", after natural deposits were found "in France at Osbann (BasRhin), the Parc (l'Ain) and the Puy-de-la-Poix (Puy-de-Dome)", although it could also be made artificially. One of the earliest uses in France was the laying of about 24,000 square yards of Seyssel asphalt at the Place de la Concorde in 1835.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In which year did an edition of Mechanics Magazine cite an early use of asphalt in Spain?
Ah, so.. unanswerable

People of Ashkenazi descent constitute around 47.5% of Israeli Jews (and therefore 3536% of Israelis). They have played a prominent role in the economy, media, and politics of Israel since its founding. During the first decades of Israel as a state, strong cultural conflict occurred between Sephardic and Ashkenazi Jews (mainly east European Ashkenazim). The roots of this conflict, which still exists to a much smaller extent in present-day Israeli society, are chiefly attributed to the concept of the "melting pot". That is to say, all Jewish immigrants who arrived in Israel were strongly encouraged to "melt down" their own particular exilic identities within the general social "pot" in order to become Israeli.

Ah, so.. 47.5%

Antarctica has no indigenous population and there is no evidence that it was seen by humans until the 19th century. However, belief in the existence of a Terra Australisa vast continent in the far south of the globe to "balance" the northern lands of Europe, Asia and North Africahad existed since the times of Ptolemy (1st century AD), who suggested the idea to preserve the symmetry of all known landmasses in the world. Even in the late 17th century, after explorers had found that South America and Australia were not part of the fabled "Antarctica", geographers believed that the continent was much larger than its actual size.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the vast continent in the far north?
Ah, so..
