Passage: Including the 2014 season, the Cowboys have won the NFC East 22 times in their 54-year history. After quarterback Tony Romo completed a 25-yard touchdown pass to TE Jason Witten late in the third quarter, Romo eclipsed Troy Aikman as the all-time leader in passing yards in franchise history. The throw put Romo at 32,961 passing yards in his career, passing Aikman's career total of 32,942. Romo finished the game with 218 yards, putting him at 32,971 for his career. At the start of the game, Murray had a total of 1,686 yards on the season and needed only 87 yards to pass Hall of Famer Emmitt Smith's team record for the most rushing yards in a single season with 1,773 yards set in 1995. However, with Murray still nursing the injury, coupled with an early Cowboys rout, Murray ended up with only 22 carries for 59 yards on the day, leaving him with a total of 1,745 yards for the year, just 28 yards short of Smith's single season record with one more game left to be played. 
Question: How many yards did Romo pass Aikman in yards passing this game? 
Answer type: Number

Passage: By the end of 1594, certain League members still worked against Henry across the country, but all relied on Spain's support. In January 1595, the king declared war on Spain to show Catholics that Spain was using religion as a cover for an attack on the French state—and to show Protestants that his conversion had not made him a puppet of Spain. Also, he hoped to take the war to Spain and make territorial gain. The conflict mostly consisted of military action aimed at League members, such as the Battle of Fontaine-Française, though the Spanish launched a concerted offensive in 1595, taking Doullens, Cambrai and Le Catelet and in the spring of 1596 capturing Calais by April. Following the Spanish capture of Amiens in March 1597 the French crown laid siege until its surrender in September. With that victory Henry's concerns then turned to the situation in Brittany where he promulgated the Edict of Nantes and sent Bellièvre and Brulart de Sillery to negotiate a peace with Spain. The war was drawn to an official close after the Edict of Nantes, with the Peace of Vervins in May 1598. 
Question: How many years did the war last?
