Question: Passage: In 1994, responding to the need for a more useful system for describing chronic pain, the International Association for the Study of Pain (IASP) classified pain according to specific characteristics: (1) region of the body involved (e.g. abdomen, lower limbs), (2) system whose dysfunction may be causing the pain (e.g., nervous, gastrointestinal), (3) duration and pattern of occurrence, (4) intensity and time since onset, and (5) etiology. However, this system has been criticized by Clifford J. Woolf and others as inadequate for guiding research and treatment. Woolf suggests three classes of pain : (1) nociceptive pain, (2) inflammatory pain which is associated with tissue damage and the infiltration of immune cells, and (3) pathological pain which is a disease state caused by damage to the nervous system or by its abnormal function (e.g. fibromyalgia, irritable bowel syndrome, tension type headache, etc.).

Answer: What did the ISAP do in 1949?


Question: Passage: As a uniformed military service, the Army is part of the Department of the Army, which is one of the three military departments of the Department of Defense. The U.S. Army is headed by a civilian senior appointed civil servant, the Secretary of the Army (SECARMY), and by a chief military officer, the Chief of Staff of the Army (CSA) who is also a member of the Joint Chiefs of Staff. In the fiscal year 2016, the projected end strength for the Regular Army (USA) was 475,000 soldiers; the Army National Guard (ARNG) had 342,000 soldiers, and the United States Army Reserve (USAR) had 198,000 soldiers; the combined-component strength of the U.S. Army was 1,015,000 soldiers. As a branch of the armed forces, the mission of the U.S. Army is "to fight and win our Nation's wars, by providing prompt, sustained, land dominance, across the full range of military operations and the spectrum of conflict, in support of combatant commanders." The service participates in conflicts worldwide and is the major ground-based offensive and defensive force.

Question: Passage: Agriculture and forestry have declined in importance over the decades. Nevertheless, they are more important than in the most other areas of Germany, especially within rural regions. 54% of Thuringia's territory is in agricultural use. The fertile basins such as the large Thuringian Basin or the smaller Goldene Aue, Orlasenke and Osterland are in intensive use for growing cereals, vegetables, fruits and energy crops. Important products are apples, strawberries, cherries and plums in the fruit sector, cabbage, potatoes, cauliflower, tomatoes (grown in greenhouses), onions, cucumbers and asparagus in the vegetable sector, as well as maize, rapeseed, wheat, barley and sugar beets in the crop sector.

Answer:
What is something no longer important to Thuringia compared to most areas of Germany?
