Question: Passage: The squadron of Vasco da Gama left Portugal in 1497, rounded the Cape and continued along the coast of East Africa, where a local pilot was brought on board who guided them across the Indian Ocean, reaching Calicut in western India in May 1498. The second voyage to India was dispatched in 1500 under Pedro Álvares Cabral. While following the same south-westerly route as Gama across the Atlantic Ocean, Cabral made landfall on the Brazilian coast. This was probably an accidental discovery, but it has been speculated that the Portuguese secretly knew of Brazil's existence and that it lay on their side of the Tordesillas line. Cabral recommended to the Portuguese King that the land be settled, and two follow up voyages were sent in 1501 and 1503. The land was found to be abundant in pau-brasil, or brazilwood, from which it later inherited its name, but the failure to find gold or silver meant that for the time being Portuguese efforts were concentrated on India. On 8 July 1497 the fleet, consisting of four ships and a crew of 170 men, left Lisbon The travel led by Vasco da Gama to Calicut was the starting point for deployment of Portuguese in the African east coast and in the Indian Ocean. The first contact occurred on 20 May 1498. After some conflict, he got an ambiguous letter for trade with the Zamorin of Calicut, leaving there some men to establish a trading post. Since then explorations lost the private nature, taking place under the exclusive of the Portuguese Crown. Shortly after, the Casa da Índia was established in Lisbon to administer the royal monopoly of navigation and trade.

Question: Passage: Hoping to rebound from their divisional road loss to the 49ers, the Seahawks went home, donned their alternate uniforms, and prepared for a Week 3 duel with the Chicago Bears. Due to quarterback Matt Hasselbeck's rib injury, Seneca Wallace got the start for the game. Seattle would take flight in the first quarter with Wallace's 39-yard touchdown pass to running back Julius Jones and kicker Olindo Mare's 46-yard field goal. The Seahawks would tack on Mare's 37-yard field goal in the second quarter, yet the Bears would answer with quarterback Jay Cutler's 1-yard touchdown pass to tight end Greg Olsen. Chicago would take in the lead in the third quarter with Cutler's 7-yard touchdown pass to wide receiver Johnny Knox, followed by kicker Robbie Gould's 37-yard field goal. The Seahawks would regain the lead in the fourth quarter with Mare's 39-yard and 46-yard field goal. However, the Bears got the last laugh as Cutler hooked up with wide receiver Devin Hester on a 36-yard touchdown pass (with a successful 2-point conversion pass to wide receiver Earl Bennett). Seattle tried to rally, but Chicago's defense held on for the win.
