Their larger 90 mm M3 gun would prove, as did the eighty-eight, to make an excellent anti-tank gun as well, and was widely used late in the war in this role. Also available to the Americans at the start of the war was the 120 mm M1 gun stratosphere gun, which was the most powerful AA gun with an impressive 60,000 ft (18 km) altitude capability.

Article: At the official counting of the electoral votes on January 6, a motion was made contesting Ohio's electoral votes. Because the motion was supported by at least one member of both the House of Representatives and the Senate, election law mandated that each house retire to debate and vote on the motion. In the House of Representatives, the motion was supported by 31 Democrats. It was opposed by 178 Republicans, 88 Democrats and one independent. Not voting were 52 Republicans and 80 Democrats. Four people elected to the House had not yet taken office, and one seat was vacant. In the Senate, it was supported only by its maker, Senator Boxer, with 74 Senators opposed and 25 not voting. During the debate, no Senator argued that the outcome of the election should be changed by either court challenge or revote. Senator Boxer claimed that she had made the motion not to challenge the outcome, but to "shed the light of truth on these irregularities."

Question: What was the decision regarding the motion to re-count the votes, after each House finalized their debates?
Ans: During the debate, no Senator argued that the outcome of the election should be changed by either court challenge or revote

Article: Formal schooling did not start in Hungary until the age of ten. Instead, governesses taught von Neumann, his brothers and his cousins. Max believed that knowledge of languages other than Hungarian was essential, so the children were tutored in English, French, German and Italian. By the age of 8, von Neumann was familiar with differential and integral calculus, but he was particularly interested in history, reading his way through Wilhelm Oncken's Allgemeine Geschichte in Einzeldarstellungen. A copy was contained in a private library Max purchased. One of the rooms in the apartment was converted into a library and reading room, with bookshelves from ceiling to floor.

Question: What languages were Von Neumann and his siblings taught?
Ans: English, French, German and Italian

Article: By the 1990s Mexico City had become infamous as one of the world's most polluted cities; however the city has become a model for dramatically lowering pollution levels. By 2014 carbon monoxide pollution had dropped dramatically, while levels of sulfur dioxide and nitrogen dioxide were nearly three times lower than in 1992. The levels of signature pollutants in Mexico City are similar to those of Los Angeles.[citation needed] Despite the cleanup, the metropolitan area is still the most ozone-polluted part of the country, with ozone levels 2.5 times beyond WHO-defined safe limits.

Question: How bad is the ozone in Mexico City?
Ans:
2.5 times beyond WHO-defined safe limits
