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: In addition to Carboniferous, what other insect order is inclusive of extant groups, stem groups and Paleozoic groups?
****
So... Early Permian


Here is a question about this article: The bombing failed to demoralise the British into surrender or significantly damage the war economy. The eight months of bombing never seriously hampered British production and the war industries continued to operate and expand. The Blitz was only authorised when the Luftwaffe had failed to meet preconditions for a 1940 launch of Operation Sea Lion, the provisionally planned German invasion of Britain. By May 1941 the threat of an invasion of Britain had passed, and Hitler's attention had turned to Operation Barbarossa in the East. In comparison to the later Allied bombing campaign against Germany, the Blitz resulted in relatively few casualties; the British bombing of Hamburg in July 1943 inflicted some 42,000 civilian deaths, about the same as the entire Blitz.
What is the answer to this question: Who was the leader of the Luftwaffe? 
****
So... Hitler


Here is a question about this article: By the end of the 17th century, the Chinese economy had recovered from the devastation caused by the wars in which the Ming dynasty were overthrown, and the resulting breakdown of order. In the following century, markets continued to expand as in the late Ming period, but with more trade between regions, a greater dependence on overseas markets and a greatly increased population. After the re-opening of the southeast coast, which had been closed in the late 17th century, foreign trade was quickly re-established, and was expanding at 4% per annum throughout the latter part of the 18th century. China continued to export tea, silk and manufactures, creating a large, favorable trade balance with the West. The resulting inflow of silver expanded the money supply, facilitating the growth of competitive and stable markets.
What is the answer to this question: What did the Chinese get paid for their goods?
****
So...
silver
