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.).

This steady economic progress has earned Armenia increasing support from international institutions. The International Monetary Fund (IMF), World Bank, European Bank for Reconstruction and Development (EBRD), and other international financial institutions (IFIs) and foreign countries are extending considerable grants and loans. Loans to Armenia since 1993 exceed $1.1 billion. These loans are targeted at reducing the budget deficit and stabilizing the currency; developing private businesses; energy; agriculture; food processing; transportation; the health and education sectors; and ongoing rehabilitation in the earthquake zone. The government joined the World Trade Organization on 5 February 2003. But one of the main sources of foreign direct investments remains the Armenian diaspora, which finances major parts of the reconstruction of infrastructure and other public projects. Being a growing democratic state, Armenia also hopes to get more financial aid from the Western World.
What does IMF stand for?
A: International Monetary Fund

Question: Today both the Papireto river and the Kemonia are covered up by buildings. However, the shape of the former watercourses can still be recognised today, because the streets that were built on them follow their shapes. Today the only waterway not drained yet is the Oreto river that divides the downtown of the city from the western uptown and the industrial districts. In the basins there were, though, many seasonal torrents that helped formed swampy plains, reclaimed during history; a good example of which can be found in the borough of Mondello.
Is there an answer to this question: What river divides the easr and west sides of the city?

Answer: unanswerable

Question: The thoracic segments have one ganglion on each side, which are connected into a pair, one pair per segment. This arrangement is also seen in the abdomen but only in the first eight segments. Many species of insects have reduced numbers of ganglia due to fusion or reduction. Some cockroaches have just six ganglia in the abdomen, whereas the wasp Vespa crabro has only two in the thorax and three in the abdomen. Some insects, like the house fly Musca domestica, have all the body ganglia fused into a single large thoracic ganglion.
Is there an answer to this question: What other location on an insect are ganglia located?

Answer:
abdomen
