[Q]: Passage: A series of experiments performed from the late 1800s to the early 1900s revealed that diabetes is caused by the absence of a substance normally produced by the pancreas. In 1869, Oskar Minkowski and Joseph von Mering found that diabetes could be induced in dogs by surgical removal of the pancreas. In 1921, Canadian professor Frederick Banting and his student Charles Best repeated this study, and found that injections of pancreatic extract reversed the symptoms produced by pancreas removal. Soon, the extract was demonstrated to work in people, but development of insulin therapy as a routine medical procedure was delayed by difficulties in producing the material in sufficient quantity and with reproducible purity. The researchers sought assistance from industrial collaborators at Eli Lilly and Co. based on the company's experience with large scale purification of biological materials. Chemist George Walden of Eli Lilly and Company found that careful adjustment of the pH of the extract allowed a relatively pure grade of insulin to be produced. Under pressure from Toronto University and a potential patent challenge by academic scientists who had independently developed a similar purification method, an agreement was reached for non-exclusive production of insulin by multiple companies. Prior to the discovery and widespread availability of insulin therapy the life expectancy of diabetics was only a few months. Question: Who discovered that pancreatic extract reversed symptoms of pancreas removal?
[A]: Frederick Banting and his student Charles Best


[Q]: Passage: In 2011, it became apparent that the bail-out would be insufficient and a second bail-out amounting to €130 billion ($173 billion) was agreed in 2012, subject to strict conditions, including financial reforms and further austerity measures. As part of the deal, there was to be a 53% reduction in the Greek debt burden to private creditors and any profits made by Eurozone central banks on their holdings of Greek debt are to be repatriated back to Greece. Greece achieved a primary government budget surplus in 2013. In April 2014, Greece returned to the global bond market as it successfully sold €3 billion worth of five-year government bonds at a yield of 4.95%. Greece returned to growth after six years of economic decline in the second quarter of 2014, and was the Eurozone's fastest-growing economy in the third quarter. Question: In what year did Greece realize a budget surplus?
[A]: 2013


[Q]: Passage: The official policy of the U.S. Government is that Thailand was not an ally of the Axis, and that the United States was not at war with Thailand. The policy of the U.S. Government ever since 1945 has been to treat Thailand not as a former enemy, but rather as a country which had been forced into certain actions by Japanese blackmail, before being occupied by Japanese troops. Thailand has been treated by the United States in the same way as such other Axis-occupied countries as Belgium, Czechoslovakia, Denmark, Greece, Norway, Poland, and the Netherlands. Question: Is Thailand treated differently than other Axis countries?
[A]:
the same way
