PROBLEM: 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: How many years passed between the first and fourth voyage to India?

PROBLEM: Passage: Following their bye week, the Raiders traveled to Mexico City for a home game against the AFC-leading Patriots. With a loss by the Chiefs earlier in the day, the Raiders looked to move within one game of the division lead. The Patriots quickly shut out any hope of a win, scoring touchdowns on two of their first three possessions to take a 14-0 lead. With under two minutes remaining in the half, the Raiders drove inside the New England 20 yard line in an attempt to cut the lead in half. Derek Carr hit Seth Roberts at the New England three, but Roberts did not properly secure the ball and fumbled, turning the ball over to Tom Brady and the Patriots with 33 seconds remaining in the half. New England quickly moved to the Raider 45 and Stephen Gostkowski connected on a 62-yard field goal as the half ended to move the lead to 17-0. In the second half, things got even worse for the Raiders as the Patriots scored on their third play, a Brady 64-yard pass to Brandin Cooks to extend the lead to 24 and end any hope of a Raider win. Two more Gostkowski field goals in the third quarter moved the lead to 30-0 entering the fourth quarter. Carr did hit Amari Cooper from nine yards out and converted the two-point play early in the fourth quarter. Another Gostkowski field goal ended the scoring as the Patriots dismantled the Raiders 33-8. The loss moved the Raiders to 4-6 on the season as they remained two games behind the Chiefs in the AFC West. The Raiders were out-gained 420-344 on the day as the Raiders' defense continued its season-long struggle.

PROBLEM: Passage: Nu Phoenicis is a yellow-white main sequence star of spectral type F9V and magnitude 4.96. Lying some 49 light years distant, it is around 1.2 times as massive as our sun, and likely to be surrounded by a disk of dust. It is the closest star in the constellation that is visible with the unaided eye. Gliese 915 is a white dwarf only 26 light years away. It is of magnitude 13.05, too faint to be seen with the naked eye. White dwarfs are extremely dense stars compacted into a volume the size of the Earth. With around 85% of the mass of the Sun, Gliese 915 has a surface gravity of 108.39 ± 0.01 (2.45 · 108) centimetre·second−2, or approximately 250,000 of Earths gravity. 
Question: How many light years closer is Gliese 915 than Nu Phoenicis?
