Input: Nutrition
Animal tissue consists of elements and compounds ingested, digested, absorbed, and circulated through the bloodstream to feed the cells of the body. Except in the unborn fetus, the digestive system is the first system involved[vague]. Digestive juices break chemical bonds in ingested molecules, and modify their conformations and energy states. Though some molecules are absorbed into the bloodstream unchanged, digestive processes release them from the matrix of foods. Unabsorbed matter, along with some waste products of metabolism, is eliminated from the body in the feces.

Through what part of the body are nutrients transported to feed cells?
Output: bloodstream

Input: Franco-Prussian War
The Prussian army was controlled by the General Staff, under Field Marshal Helmuth von Moltke. The Prussian army was unique in Europe for having the only such organisation in existence, whose purpose in peacetime was to prepare the overall war strategy, and in wartime to direct operational movement and organise logistics and communications. The officers of the General Staff were hand-picked from the Prussian Kriegsakademie (War Academy). Moltke embraced new technology, particularly the railroad and telegraph, to coordinate and accelerate mobilisation of large forces.

What entity controlled the Prussian army?
Output: the General Staff

Input: Tennessee
The area now known as Tennessee was first inhabited by Paleo-Indians nearly 12,000 years ago. The names of the cultural groups that inhabited the area between first settlement and the time of European contact are unknown, but several distinct cultural phases have been named by archaeologists, including Archaic (80001000 BC), Woodland (1000 BC1000 AD), and Mississippian (10001600 AD), whose chiefdoms were the cultural predecessors of the Muscogee people who inhabited the Tennessee River Valley before Cherokee migration into the river's headwaters.

How many years ago was Tennessee first inhabited by humans?
Output: 12,000

Input: Hunter-gatherer
Many hunter-gatherers consciously manipulate the landscape through cutting or burning undesirable plants while encouraging desirable ones, some even going to the extent of slash-and-burn to create habitat for game animals. These activities are on an entirely different scale to those associated with agriculture, but they are nevertheless domestication on some level. Today, almost all hunter-gatherers depend to some extent upon domesticated food sources either produced part-time or traded for products acquired in the wild.

How do they manage the landscape?
Output:
cutting or burning undesirable plants
