Here is a question about this article: Late Carboniferous and Early Permian insect orders include both extant groups, their stem groups, and a number of Paleozoic groups, now extinct. During this era, some giant dragonfly-like forms reached wingspans of 55 to 70 cm (22 to 28 in), making them far larger than any living insect. This gigantism may have been due to higher atmospheric oxygen levels that allowed increased respiratory efficiency relative to today. The lack of flying vertebrates could have been another factor. Most extinct orders of insects developed during the Permian period that began around 270 million years ago. Many of the early groups became extinct during the Permian-Triassic extinction event, the largest mass extinction in the history of the Earth, around 252 million years ago.
What is the answer to this question: How wide were the wingspans of the dragonfly-like forms?
****
So... 55 to 70 cm

Here is a question about this article: One elector in Minnesota cast a ballot for president with the name of "John Ewards" [sic] written on it. The Electoral College officials certified this ballot as a vote for John Edwards for president. The remaining nine electors cast ballots for John Kerry. All ten electors in the state cast ballots for John Edwards for vice president (John Edwards's name was spelled correctly on all ballots for vice president). This was the first time in U.S. history that an elector had cast a vote for the same person to be both president and vice president; another faithless elector in the 1800 election had voted twice for Aaron Burr, but under that electoral system only votes for the president's position were cast, with the runner-up in the Electoral College becoming vice president (and the second vote for Burr was discounted and re-assigned to Thomas Jefferson in any event, as it violated Electoral College rules).
What is the answer to this question: In the 1800 election, why did Thomas Jefferson get the second vote?
****
So... it violated Electoral College rules

Here is a question about this article: The two became friends, and for many years lived in close proximity in Paris, Chopin at 38 Rue de la Chaussee-d'Antin, and Liszt at the Hotel de France on the Rue Lafitte, a few blocks away. They performed together on seven occasions between 1833 and 1841. The first, on 2 April 1833, was at a benefit concert organized by Hector Berlioz for his bankrupt Shakespearean actress wife Harriet Smithson, during which they played George Onslow's Sonata in F minor for piano duet. Later joint appearances included a benefit concert for the Benevolent Association of Polish Ladies in Paris. Their last appearance together in public was for a charity concert conducted for the Beethoven Memorial in Bonn, held at the Salle Pleyel and the Paris Conservatory on 25 and 26 April 1841.
What is the answer to this question: At which two establishments was the last of these performances conducted at on 25 and 26 April 1841?

So...
Salle Pleyel and the Paris Conservatory
