Input: Alps
Important geological concepts were established as naturalists began studying the rock formations of the Alps in the 18th century. In the mid-19th century the now defunct theory of geosynclines was used to explain the presence of "folded" mountain chains but by the mid-20th century the theory of plate tectonics became widely accepted.

When did the studying of rock formations begin in the Alps?
Output: the 18th century

Input: Plymouth
Plymouth's gross value added (a measure of the size of its economy) was 5,169 million GBP in 2013 making up 25% of Devon's GVA. Its GVA per person was 19,943 and compared to the national average of 23,755, was 3,812 lower. Plymouth's unemployment rate was 7.0% in 2014 which was 2.0 points higher than the South West average and 0.8 points higher than the average for Great Britain (England, Wales and Scotland).

What percentage of Devon's GVA does Plymouth comprise in 2013?
Output: 25%

Input: Annelid
Nearly all polychaetes have parapodia that function as limbs, while other major annelid groups lack them. Parapodia are unjointed paired extensions of the body wall, and their muscles are derived from the circular muscles of the body. They are often supported internally by one or more large, thick chetae. The parapodia of burrowing and tube-dwelling polychaetes are often just ridges whose tips bear hooked chetae. In active crawlers and swimmers the parapodia are often divided into large upper and lower paddles on a very short trunk, and the paddles are generally fringed with chetae and sometimes with cirri (fused bundles of cilia) and gills.

What kind of parapodia do burrowing annelids often have?
Output: ridges whose tips bear hooked chetae

Input: General Electric
GE has a history of some of its activities giving rise to large-scale air and water pollution. Based on year 2000 data, researchers at the Political Economy Research Institute listed the corporation as the fourth-largest corporate producer of air pollution in the United States, with more than 4.4 million pounds per year (2,000 tons) of toxic chemicals released into the air. GE has also been implicated in the creation of toxic waste. According to EPA documents, only the United States Government, Honeywell, and Chevron Corporation are responsible for producing more Superfund toxic waste sites.

Which organization identified GE as the fourth largest corporate producer of air pollution in the US?
Output:
Political Economy Research Institute
