Question:
After their success in the Morea, the Ottomans moved against the Venetian-held Ionian Islands. They occupied the island of Lefkada , which the Venetians had taken in 1684, and the fort of Butrinto opposite the city of Corfu. On 8 July 1716, an Ottoman army of 33,000 men landed on Corfu, the most important of the Ionian islands. Despite an indecisive naval battle on the same day, the Ottoman land army continued its disembarkment and advanced towards the city of Corfu. On 19 July, after capturing the outlying forts of Mantouki, Garitsa, Avrami and of the Saviour, the siege began. The defence was led by Count Johann Matthias von der Schulenburg, who had roughly 8,000 men at his command. The extensive fortifications and the determination of the defenders withstood several assaults. After a great storm on 9 August—which the defenders attributed to the intervention of Corfu's patron saint, Saint Spyridon—caused significant casualties among the besiegers, the siege was broken off on 11 August and the last Ottoman forces withdrew on 20 August.

How many days after a great storm was the siege broken off?

Answer:
2


Question:
Until the mid-20th century most of Yucatán's contact with the outside world was by sea; trade with the US and Cuba, as well as Europe and other Caribbean islands, was more significant than that with the rest of Mexico. In the 1950s Yucatán was linked to the rest of Mexico by railway, followed by highway in the 1960s, ending the region's comparative isolation. Today Yucatán still demonstrates a unique culture from the rest of Mexico, including its own style of food. Commercial jet airplanes began arriving in Mérida in the 1960s, and additional international airports were built first in Cozumel and then in the new planned resort community of Cancún in the 1980s, making tourism a major force in the economy of the Yucatán Peninsula. The first Maya governor of Yucatán, Francisco Luna Kan, was elected in 1976. Today, the Yucatán Peninsula is a major tourism destination, as well as home to one of the largest indigenous populations in Mexico, the Maya people.

How many commercial airports were mentioned?

Answer:
3
