Problem: Today both the Papireto river and the Kemonia are covered up by buildings. However, the shape of the former watercourses can still be recognised today, because the streets that were built on them follow their shapes. Today the only waterway not drained yet is the Oreto river that divides the downtown of the city from the western uptown and the industrial districts. In the basins there were, though, many seasonal torrents that helped formed swampy plains, reclaimed during history; a good example of which can be found in the borough of Mondello.
What follows the former course of the Oreto?

Problem: With the decline of Herodians, Judea, transformed into a Roman province, became the site of a violent struggle of Jews against Greco-Romans, culminating in the Jewish-Roman Wars, ending in wide-scale destruction, expulsions, and genocide. Jewish presence in the region significantly dwindled after the failure of the Bar Kokhba revolt against the Roman Empire in 132 CE. Nevertheless, there was a continuous small Jewish presence and Galilee became its religious center. The Mishnah and part of the Talmud, central Jewish texts, were composed during the 2nd to 4th centuries CE in Tiberias and Jerusalem. The region came to be populated predominantly by Greco-Romans on the coast and Samaritans in the hill-country. Christianity was gradually evolving over Roman paganism, when the area stood under Byzantine rule. Through the 5th and 6th centuries, the dramatic events of the repeated Samaritan revolts reshaped the land, with massive destruction to Byzantine Christian and Samaritan societies and a resulting decrease of the population. After the Persian conquest and the installation of a short-lived Jewish Commonwealth in 614 CE, the Byzantine Empire reconquered the country in 628.
Who conquered the country in 628?

Answer: Byzantine Empire


Problem: The cultural role of copper has been important, particularly in currency. Romans in the 6th through 3rd centuries BC used copper lumps as money. At first, the copper itself was valued, but gradually the shape and look of the copper became more important. Julius Caesar had his own coins made from brass, while Octavianus Augustus Caesar's coins were made from Cu-Pb-Sn alloys. With an estimated annual output of around 15,000 t, Roman copper mining and smelting activities reached a scale unsurpassed until the time of the Industrial Revolution; the provinces most intensely mined were those of Hispania, Cyprus and in Central Europe.
Who had his own trees produced out of brass?
