Context and question: Roncalli was summoned to the final ballot of the conclave at 4:00 pm. He was elected pope at 4:30 pm with a total of 38 votes. After the long pontificate of Pope Pius XII, the cardinals chose a man who – it was presumed because of his advanced age – would be a short-term or "stop-gap" pope. They wished to choose a candidate who would do little during the new pontificate. Upon his election, Cardinal Eugene Tisserant asked him the ritual questions of whether he would accept and if so, what name he would take for himself. Roncalli gave the first of his many surprises when he chose "John" as his regnal name. Roncalli's exact words were "I will be called John". This was the first time in over 500 years that this name had been chosen; previous popes had avoided its use since the time of the Antipope John XXIII during the Western Schism several centuries before.
When was the final ballot of the conclave?
Answer: 4:00 pm
Context and question: The production for sulfidic zinc ores produces large amounts of sulfur dioxide and cadmium vapor. Smelter slag and other residues of process also contain significant amounts of heavy metals. About 1.1 million tonnes of metallic zinc and 130 thousand tonnes of lead were mined and smelted in the Belgian towns of La Calamine and Plombières between 1806 and 1882. The dumps of the past mining operations leach significant amounts of zinc and cadmium, and, as a result, the sediments of the Geul River contain significant amounts of heavy metals. About two thousand years ago emissions of zinc from mining and smelting totaled 10 thousand tonnes a year. After increasing 10-fold from 1850, zinc emissions peaked at 3.4 million tonnes per year in the 1980s and declined to 2.7 million tonnes in the 1990s, although a 2005 study of the Arctic troposphere found that the concentrations there did not reflect the decline. Anthropogenic and natural emissions occur at a ratio of 20 to 1.
Why does the Geul River contain no heavy metals?
Answer: unanswerable
Context and question: The depression had devastating effects in virtually every country, rich or poor. International trade plunged by half to two-thirds, as did personal income, tax revenue, prices and profits. Cities all around the world were hit hard, especially those dependent on heavy industry. Construction was virtually halted in many countries. Farming and rural areas suffered as crop prices fell by roughly 60 percent. Facing plummeting demand with few alternate sources of jobs, areas dependent on primary sector industries suffered the most.
How far did crop prices fall?
Answer:
60 percent
