Q: Because of the combination of a relatively small Omani population and a fast-growing oil-driven economy, Oman has attracted many migrants. At the 2014 census the total expatriate population was 1,789,000 or 43.7% of the population. Most migrants are males from India (465,660 for both sexes), Bangladesh (107,125) or Pakistan (84,658). Female migrant workers are mainly from Indonesia (25,300), the Philippines (15,651) or Sri Lanka (10,178). Migrants from Arab countries account for 68,986 migrants (Egypt 29,877, Jordan 7,403, Sudan 6,867, UAE 6,426, Iraq 4,159, Saudi Arabia 725, Bahrain 388, Qatar 168, other 12,683) and other Asian countries for 12,939 migrants. There were 8,541 migrants from Europe, 1,540 from the United States and 15,565 from other countries.
Are there fewer migrants from Arab countries or from Asian countries?
A: Arab

Q: The Ottoman incursions in Dalmatia escalated to the point where Venice was forced to sign a treaty with Vladislaus II of Hungary and Pope Alexander VI by which they pledged 140,000 ducats a year for the Kingdom of Hungary to actively defend its southern Croatian territories, which aided the defence of Venetian Dalmatia, signed after long negotiations on 13 May 1501. In 1501 Feriz Beg captured Durazzo in Venetian Albania. By the end of 1502, Venice and the Ottoman Empire agreed on an armistice. On 31 January 1503, Venice signed another treaty with Vladislaus II, having already paid 124,000 ducats through the previous treaty, to pay 30,000 ducats a year for the same purpose. In 1503, Turkish cavalry raids reached Venetian territory in Northern Italy, and Venice was forced to recognize the Ottoman gains, ending the war. The economy of the Venetian cities in Dalmatia was severely impacted by the Turkish occupation of the hinterland during this war.
How many ducats will Venice had given Vladislaus II from a signed Treaty, 3000 a year and 124,000?
A: 127000

Q: By 1474, cannons had been introduced in Mdina. Other extensive preparations for an attack were made in the 1480s, when the fortifications were once again improved under the direction of Sicilian military engineers. At this point, some buildings in Rabat were demolished to clear the fortifications' line of fire. By 1522, the fortifications were being modernized with the construction of embrasures. However, the walls were still regarded as obsolete, since they lacked bastions and could not resist bombardment from modern artillery. Most of the medieval walls of Mdina were gradually dismantled between the 1530s and 1720s, when the city's fortifications were being upgraded by the Hospitallers. One of the most significant visible remnants of the medieval fortifications is the Greeks Gate and the surrounding curtain walls, which still retains its medieval form apart from the outer portal which was built in the 18th century. Parts of the double walls, including the remains of two gun loops, still stand between the gate and the Torre dello Standardo. Most of the northern and eastern walls date back to the medieval period, although some sections were rebuilt by the Hospitallers. The northern ramparts contain a medieval wall tower, while the remains of Byzantine antemurals and the foundations of a late 15th-century artillery platform have been found in the eastern walls.
What city has remnants of some sections of wall that were rebuilt by the Hospitallers during their fortification?
A:
Mdina
