Question: In 1274, the Mongol-founded Yuan dynasty in China sent a force of some 40,000 men and 900 ships to invade Japan in northern Kyūshū. Japan mustered a mere 10,000 samurai to meet this threat. The invading army was harassed by major thunderstorms throughout the invasion, which aided the defenders by inflicting heavy casualties. The Yuan army was eventually recalled and the invasion was called off. The Mongol invaders used small bombs, which was likely the first appearance of bombs and gunpowder in Japan.

Question: The Palácio da Alvorada is the official residence of the President of Brazil. The palace was designed, along with the rest of the city of Brasília, by Oscar Niemeyer and inaugurated in 1958. One of the first structures built in the republic's new capital city, the "Alvorada" lies on a peninsula at the margins of Lake Paranoá. The principles of simplicity and modernity, that in the past characterized the great works of architecture, motivated Niemeyer. The viewer has an impression of looking at a glass box, softly landed on the ground with the support of thin external columns. The building has an area of 7,000 m2 with three floors consisting of the basement, landing, and second floor. The auditorium, kitchen, laundry, medical center, and administration offices are at basement level. The rooms used by the presidency for official receptions are on the landing. The second floor has four suites, two apartments, and various private rooms which make up the residential part of the palace. The building also has a library, a heated Olympic-sized swimming pool, a music room, two dining rooms and various meeting rooms. A chapel and heliport are in adjacent buildings.
Is there an answer to this question: How large is the Alvorada?

Answer: 7,000 m2


Question: The formation of the Alps (the Alpine orogeny) was an episodic process that began about 300 million years ago. In the Paleozoic Era the Pangaean supercontinent consisted of a single tectonic plate; it broke into separate plates during the Mesozoic Era and the Tethys sea developed between Laurasia and Gondwana during the Jurassic Period. The Tethys was later squeezed between colliding plates causing the formation of mountain ranges called the Alpide belt, from Gibraltar through the Himalayas to Indonesia—a process that began at the end of the Mesozoic and continues into the present. The formation of the Alps was a segment of this orogenic process, caused by the collision between the African and the Eurasian plates that began in the late Cretaceous Period.
Is there an answer to this question: The Tethys sea developed during what period of time? 

Answer:
Jurassic Period
