question: 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: How many years after cannons were introduced in Mdina did the modernization of fortifications with the construction of embrasures begin?
answer: 48

question: Eta Carinae is the most prominent variable star in Carina; with a mass of approximately 100 solar masses and 4 million times as bright as the Sun. It was first discovered to be unusual in 1677, when its magnitude suddenly rose to 4, attracting the attention of Edmond Halley. Eta Carinae is inside NGC 3372, commonly called the Carina Nebula. It had a long outburst in 1827, when it brightened to magnitude 1, only fading to magnitude 1.5 in 1828. Its most prominent outburst made Eta Carinae the equal of Sirius; it brightened to magnitude −1.5 in 1843. However, since 1843, Eta Carinae has remained relatively placid, having a magnitude between 6.5 and 7.9. However, in 1998, it brightened again, though only to magnitude 5.0, a far less drastic outburst. Eta Carinae is a binary star, with a companion that has a period of 5.5 years; the two stars are surrounded by the Homunculus Nebula, which is composed of gas that was ejected in 1843.
Answer this question: How many years after Eta Carinae was first discovered to be unusual did it brighten to magnitude −1.5?
answer: 166

question: The Texans opened the 2006 season at home against the Philadelphia Eagles on September 10.  The Texans looked sharp early with QB David Carr throwing a 25-yard TD pass to former Bills WR Eric Moulds in the 1st Quarter.  The Eagles would tie the game with QB Donovan McNabb throwing a 42-yard TD strike to WR Donte' Stallworth. The Texans would retake the lead, however, after a 34-yard FG from K Kris Brown. Philadelphia took the lead late in the half with McNabb throwing a 5-yard TD pass to WR Reggie Brown and held on to it for the rest of the game.  In the third quarter, McNabb hooked up with RB Brian Westbrook with a 31-yard pass and then, opposing kicker David Akers ended the game in the fourth quarter with a 42-yard field goal. David Carr finished 18-of-27 for 208 yards and a touchdown and was sacked five times.
