Problem: Pain:

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.).

Problem: The transition from independence to a relatively minor part of a larger union was not easily accepted. To quell uprisings Charles V was struggling to exert his power over the citizens of the city, who had struggled to gain a certain level of independence from the bishops and were not willing to cede this to their new lord. The heavily fortified castle Vredenburg was built to house a large garrison whose main task was to maintain control over the city. The castle would last less than 50 years before it was demolished in an uprising in the early stages of the Dutch Revolt.
What was the purpose of the castle

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
A number of vessels visiting the islands were attacked and their crews killed. In 1834, Captain DonSette and his crew were killed. Similarly, in 1845 the schooner Naiad punished a native for stealing with such violence that the natives attacked the ship. Later that year a whaler's boat crew were killed. In 1852 the San Francisco-based ships Glencoe and Sea Nymph were attacked and everyone aboard except for one crew member were killed. The violence was usually attributed as a response to the ill treatment of the natives in response to petty theft, which was a common practice. In 1857, two missionaries successfully settled on Ebon, living among the natives through at least 1870.:3
Out of what city was the Sea Nymph sailing?
A: San Francisco

Problem: Idealism:

In philosophy, idealism is the group of philosophies which assert that reality, or reality as we can know it, is fundamentally mental, mentally constructed, or otherwise immaterial. Epistemologically, idealism manifests as a skepticism about the possibility of knowing any mind-independent thing. In a sociological sense, idealism emphasizes how human ideasespecially beliefs and valuesshape society.
