question: Following the widespread use of poliovirus vaccine in the mid-1950s, the incidence of poliomyelitis declined dramatically in many industrialized countries. A global effort to Eradication of infectious disease polio began in 1988, led by the World Health Organization, UNICEF, and The Rotary Foundation. These efforts have reduced the number of annual diagnosed cases by 99.9 percent; from an estimated 350,000 cases in 1988 to a low of 483 cases in 2001, after which it remained at a level of about 1,000 – 2000 cases per year for a number of years. In 2015, cases decreased to 98 and further decreased in 2016 to 37 wild cases and 5 circulating vaccine-derived cases, but increased in 2017 to 22 wild cases and 91 circulating vaccine-derived cases. Polio is one of only two diseases currently the subject of a global eradication of infectious diseases, the other being Guinea worm disease. So far, the only diseases completely eradicated by humankind are smallpox, declared so, in 1980, and rinderpest, likewise, in 2011. A number of eradication milestones have already been reached, and several regions of the world have been certified polio-free.
Answer this question: What was eradicated by 2011?
answer: rinderpest

question: The Jurchens were a Tungusic-speaking group of semi-agrarian tribes inhabiting areas of northeast Asia that are now part of Northeast China. Many of the Jurchen tribes were vassals of the Liao dynasty , an empire ruled by the nomadic Khitans that included most of modern Mongolia, a portion of North China, Northeast China, northern Korea, and parts of the Russian Far East. To the south of the Liao lay the Han Chinese Song Empire . The Song and Liao were at peace, but since a military defeat to the Liao in 1005, the Song paid its northern neighbor an annual indemnity of 200,000 bolts of silk and 100,000 ounces of silver. In 1114, the chieftain Wanyan Aguda  united the disparate Jurchen tribes and led a revolt against the Liao. In 1115 he named himself emperor of the Jin "golden" dynasty . Informed by a Liao defector of the success of the Jurchen uprising, the Song emperor Huizong  and his highest military commander the eunuch Tong Guan saw the Liao weakness as an opportunity to recover the Sixteen Prefectures, a line of fortified cities and passes that the Liao had annexed from the Shatuo Turk Later Jin in 938, and that the Song had repeatedly but unsuccessfully tried to reconquer. The Song thus sought an alliance with the Jin against their common enemy the Liao.
Answer this question: How many more bolts of silk did the Song pay than ounces of silver?
answer:
100000
