Q: This time, Pagan could not do anything to retake Martaban because it was facing an existential threat from the north. The Mongols demanded tribute, in 1271 and again in 1273. When Narathihapate refused both times, the Mongols systematically invaded the country. The first invasion in 1277 defeated the Burmese at the battle of Ngasaunggyan, and secured their hold of Kanngai . In 1283-1285, their forces moved south and occupied down to Tagaung and Hanlin. The king fled to Lower Burma in 1285 before agreeing to submit to the Mongols in June 1286. Soon after the agreement was finalised, the king was assassinated in July 1287. The Mongols once again invaded south toward Pagan. Recent research indicates that Mongol armies may not have reached Pagan itself, and that even if they did, the damage they inflicted was probably minimal. But the damage was already done. All the vassal states of Pagan revolted right after the king's death, and went their own way. In the south, Wareru, the man who had seized the governorship of Martaban in 1281, consolidated Mon-speaking regions of Lower Burma, and declared Ramannadesa  independent. In the west too, Arakan stopped paying tribute. The 250-year-old Pagan Empire had ceased to exist.
How many years passed between the first invasion by the Mongols and the king's submission to the Mongols?

A: 9

Problem: While Polish-Lithuanian army concentrated in Podolia, in deep south of the enormous Commonwealth, on August 19, 1621, a Swedish army landed near Pärnu , carried by a fleet of 148 vessels . Gustav Adolf had 14,700 infantry, 3,150 cavalry and 375 cannons. Swedes immediately marched towards Riga, and besieged it on 29 August. The capital of Livonia was defended by a garrison of 300 soldiers, plus 3,700 armed residents. Lithuanian Field Hetman Krzysztof Radziwiłł had only 1,500 soldiers at his disposal, as most units were in Podolia and Red Ruthenia. Riga capitulated on September 25, after a month siege and three assaults. On October 2, Swedes captured the fortress of Dunamunde. The invaders, marching through marshes and forests to avoid Lithuanian cavalry, entered the Duchy of Courland and Semigallia, capturing its capital, Mitau without resistance. Swedes then tried to capture the fortress of Koknese, but failed to do so, after a skirmish with Lithuanian cavalry of Aleksander Gosiewski. In early January 1622, the Swedes captured Valmiera, together with several smaller Livonian castles. Meanwhile, the forces under Hetman Radziwill grew to 3 000, which enabled the Lithuanians to seal several Swedish garrisons. On January 7, Radziwiłł recaptured Mitau, but for lack of artillery, he failed to seize its castle, whose garrison did not capitulate until July 6. A few weeks later, in late July 1622, main Swedish forces reached Mittau, and a prolonged battle ensued. Since the battle turned into a stalemate, on August 10, 1622, both sides signed a truce, which in 1623 was prolonged until March 1625. During the negotiations, envoys of Gustav Adolf suggested a Swedish-Lithuanian union.

How many days after a Swedish army landed near Pärnu did the Swedes besiege Riga?
Answer: 10

Problem: 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 question based on the article: What city has remnants of some sections of wall that were rebuilt by the Hospitallers during their fortification?
A:
Mdina
