People of Italian descent numbered at 1,694, forming 0.4% of the population; people of French descent numbered at 1,064, forming 0.2% of the population. Finally, those of West Indian descent numbered at 1,393, forming 0.3% of San Juans population. Approximately 1,026 people claimed Sub-Saharan African ancestry; 719 claimed Irish American ancestry; 646 claimed German American ancestry; 431 claimed Arab American ancestry, and 346 claimed English American ancestry. There are many other ancestry groups in San Juan, but they are very scant.

P: 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.
Answer this: How many decades did most of the medieval walls of Mdina were gradually dismantled?

A: 19


P: The years between the Easter Rising of 1916 and the beginning of the War of Independence in 1919 were not bloodless. Thomas Ashe, one of the Volunteer leaders imprisoned for his role in the 1916 rebellion, died on hunger strike, after attempted force-feeding in 1917. In 1918, during disturbances arising out of the anti-conscription campaign, six civilians died in confrontations with the police and British Army and over 1,000 were arrested. Armistice Day was marked by severe rioting in Dublin, which left over 100 British soldiers injured. There were also raids for arms by the Volunteers, at least one shooting of a Royal Irish Constabulary  policeman and the burning of an RIC barracks in Kerry. In Co. Cork, four rifles were seized from the Eyeries barracks in March 1918 and men from the barracks were beaten that August. In early July 1918, Volunteers ambushed two RIC men who had been stationed to stop a feis being held on the road between Ballingeary and Ballyvourney in the first armed attack on the RIC since the Easter Rising - one was shot in the neck, the other beaten, and police carbines and ammunition were seized. Patrols in Bantry and Ballyvourney were badly beaten in September and October. The attacks brought a British military presence from the summer of 1918, which only briefly quelled the violence, and an increase in police raids. However, there was as yet no co-ordinated armed campaign against British forces or RIC.
Answer this: How many months after four rifles were seized from the Eyeries barracks were the two RIC men who had been stationed to stop a feis being held on the road between Ballingeary and Ballyvourney?

A:
