Input: Consider Input: Question: Which of the battles La Hire fought with Dunois was the deadliest? Passage:La Hire joined Charles VII in 1418, when the English army invaded France. Although not a noble, La Hire was regarded a very capable military leader as well as an accomplished rider. Three years later, in 1421 he fought at the Battle of Baugé. Along with Jean de Dunois, La Hire was involved in scouting and skirmishing in the countryside as far north as Paris. In 1427, both La Hire and Dunois relieved the siege of Montargis. He was a close comrade of Joan of Arc. He was one of the few military leaders who believed in her and the inspiration she brought, and he fought alongside her at Orleans. At the Battle of Patay, La Hire commanded the vanguard and won a great victory for France. La Hire was also known for praying before going into battle, something that could be attributed to Joan's influence. In 1430, La Hire captured the English held fortification of Château Gaillard. He was imprisoned in Dourdan in the spring of 1431. He won the Battle of Gerberoy in 1435 and was made Captain General of Normandy in 1438. His last two major military engagements occurred in 1440 at Pontoise where he assisted Dunois to capture it from the English; and in 1442 he assisted Charles of Orleans in capturing La Réole. He died at Montauban on 11 January 1443, of an unknown illness.

Input: Consider Input: Question: Which animated program that made use of the Pulfrich effect was on the air first? Passage:The effect was also used well throughout the whole 1993 Doctor Who charity special Dimensions in Time and in dream sequences of the 1997 3rd Rock from the Sun two-part season 2 finale Nightmare on Dick Street. In many countries in Europe, a series of short 3D films, produced in the Netherlands, were shown on television. Glasses were sold at a chain of petrol stations. These short films were mainly travelogues of Dutch localities. A Power Rangers Lightspeed Rescue movie called Power Rangers in 3D: Triple Force (later broadcast as two-part Trakeena's Revenge) sold on VHS through McDonald's purportedly used "Circlescan 4D" technology, which is based on the Pulfrich effect, but there was very little 3D present. In the United States and Canada, six million 3D Pulfrich glasses were distributed to viewers for an episode of Discovery Channel's Shark Week in 2000. Animated programs that employed the Pulfrich effect in specific segments of its programs include Yo Yogi!, The Bots Master, and Space Strikers; they typically achieved the effect through the use of constantly moving background and foreground layers.
