QUES: The prevalence of phantom pain in upper limb amputees is nearly 82%, and in lower limb amputees is 54%. One study found that eight days after amputation, 72 percent of patients had phantom limb pain, and six months later, 65 percent reported it. Some amputees experience continuous pain that varies in intensity or quality; others experience several bouts a day, or it may occur only once every week or two. It is often described as shooting, crushing, burning or cramping. If the pain is continuous for a long period, parts of the intact body may become sensitized, so that touching them evokes pain in the phantom limb, or phantom limb pain may accompany urination or defecation.

After six months, what percentage of people who had limbs amputated still felt pain in those limbs?
What is the answer?
ANS: 65 percent
QUES: "Hanover" is the traditional English spelling. The German spelling (with a double n) is becoming more popular in English; recent editions of encyclopedias prefer the German spelling, and the local government uses the German spelling on English websites. The English pronunciation /hnvr/, with stress on the first syllable and a reduced second syllable, is applied to both the German and English spellings, which is different from German pronunciation [hanof], with stress on the second syllable and a long second vowel. The traditional English spelling is still used in historical contexts, especially when referring to the British House of Hanover.

QUES: According to the Primary Chronicle, the territories of the East Slavs in the 9th century were divided between the Varangians and the Khazars. The Varangians are first mentioned imposing tribute from Slavic and Finnic tribes in 859. In 862, the Finnic and Slavic tribes in the area of Novgorod rebelled against the Varangians, driving them "back beyond the sea and, refusing them further tribute, set out to govern themselves."
