[EX Q]: Passage: Paris' manufacturing is mostly focused in its suburbs, and the city itself has only around 75,000 manufacturing workers, most of which are in the textile, clothing, leather goods and shoe trades. Paris region manufacturing specialises in transportation, mainly automobiles, aircraft and trains, but this is in a sharp decline: Paris proper manufacturing jobs dropped by 64 percent between 1990 and 2010, and the Paris region lost 48 percent during the same period. Most of this is due to companies relocating outside the Paris region. The Paris region's 800 aerospace companies employed 100,000. Four hundred automobile industry companies employ another 100,000 workers: many of these are centred in the Yvelines department around the Renault and PSA-Citroen plants (this department alone employs 33,000), but the industry as a whole suffered a major loss with the 2014 closing of a major Aulnay-sous-Bois Citroen assembly plant. Question: What does Paris region manufacturing specialize in?
[EX A]: transportation

[EX Q]: Passage: From 1920, Eisenhower served under a succession of talented generals – Fox Conner, John J. Pershing, Douglas MacArthur and George Marshall. He first became executive officer to General Conner in the Panama Canal Zone, where, joined by Mamie, he served until 1924. Under Conner's tutelage, he studied military history and theory (including Carl von Clausewitz's On War), and later cited Conner's enormous influence on his military thinking, saying in 1962 that "Fox Conner was the ablest man I ever knew." Conner's comment on Eisenhower was, "[He] is one of the most capable, efficient and loyal officers I have ever met." On Conner's recommendation, in 1925–26 he attended the Command and General Staff College at Fort Leavenworth, Kansas, where he graduated first in a class of 245 officers. He then served as a battalion commander at Fort Benning, Georgia, until 1927. Question: How many people were in Eisenhower's class at the Command and General Staff College?
[EX A]: 245

[EX Q]: Passage: The act of predation can be broken down into a maximum of four stages: Detection of prey, attack, capture and finally consumption. The relationship between predator and prey is one that is typically beneficial to the predator, and detrimental to the prey species. Sometimes, however, predation has indirect benefits to the prey species, though the individuals preyed upon themselves do not benefit. This means that, at each applicable stage, predator and prey species are in an evolutionary arms race to maximize their respective abilities to obtain food or avoid being eaten. This interaction has resulted in a vast array of adaptations in both groups. Question: What dilemma has resulted in many predatory adaptations?
[EX A]:
obtain food or avoid being eaten
