Input: Article: Examples of energy transformation include generating electric energy from heat energy via a steam turbine, or lifting an object against gravity using electrical energy driving a crane motor. Lifting against gravity performs mechanical work on the object and stores gravitational potential energy in the object. If the object falls to the ground, gravity does mechanical work on the object which transforms the potential energy in the gravitational field to the kinetic energy released as heat on impact with the ground. Our Sun transforms nuclear potential energy to other forms of energy; its total mass does not decrease due to that in itself (since it still contains the same total energy even if in different forms), but its mass does decrease when the energy escapes out to its surroundings, largely as radiant energy.

Now answer this question: Give one example of energy transformation.

Output: generating electric energy from heat energy via a steam turbine

Input: Article: Shortly after his birth, John was passed from Eleanor into the care of a wet nurse, a traditional practice for medieval noble families. Eleanor then left for Poitiers, the capital of Aquitaine, and sent John and his sister Joan north to Fontevrault Abbey. This may have been done with the aim of steering her youngest son, with no obvious inheritance, towards a future ecclesiastical career. Eleanor spent the next few years conspiring against her husband Henry and neither parent played a part in John's very early life. John was probably, like his brothers, assigned a magister whilst he was at Fontevrault, a teacher charged with his early education and with managing the servants of his immediate household; John was later taught by Ranulph Glanville, a leading English administrator. John spent some time as a member of the household of his eldest living brother Henry the Young King, where he probably received instruction in hunting and military skills.

Now answer this question: John was taught by who?

Output: Ranulph Glanville

Input: Article: Abnormal discoloration of wood often denotes a diseased condition, indicating unsoundness. The black check in western hemlock is the result of insect attacks. The reddish-brown streaks so common in hickory and certain other woods are mostly the result of injury by birds. The discoloration is merely an indication of an injury, and in all probability does not of itself affect the properties of the wood. Certain rot-producing fungi impart to wood characteristic colors which thus become symptomatic of weakness; however an attractive effect known as spalting produced by this process is often considered a desirable characteristic. Ordinary sap-staining is due to fungal growth, but does not necessarily produce a weakening effect.

Now answer this question: What causes the black checked pattern in the wood of western hemlocks?

Output:
insect attacks
