Problem: 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.
How many million years ago is the Permian period believed to have begun?
The answer is the following: 270

Input: Economy of Greece
In terms of ship categories, Greek companies have 22.6% of the world's tankers and 16.1% of the world's bulk carriers (in dwt). An additional equivalent of 27.45% of the world's tanker dwt is on order, with another 12.7% of bulk carriers also on order. Shipping accounts for an estimated 6% of Greek GDP, employs about 160,000 people (4% of the workforce), and represents 1/3 of the country's trade deficit. Earnings from shipping amounted to 14.1 billion in 2011, while between 2000 and 2010 Greek shipping contributed a total of 140 billion (half of the country's public debt in 2009 and 3.5 times the receipts from the European Union in the period 20002013). The 2011 ECSA report showed that there are approximately 750 Greek shipping companies in operation.

What did earnings from Greece's shipping amount to in 2011?
Output: 14.1 billion

Problem: Please answer a question about the following article about Anti-aircraft warfare:
After World War I the US Army started developing a dual-role (AA/ground) automatic 37 mm cannon, designed by John M. Browning. It was standardised in 1927 as the T9 AA cannon, but trials quickly revealed that it was worthless in the ground role. However, while the shell was a bit light (well under 2 lbs) it had a good effective ceiling and fired 125 rounds per minute; an AA carriage was developed and it entered service in 1939. The Browning 37mm proved prone to jamming, and was eventually replaced in AA units by the Bofors 40 mm. The Bofors had attracted attention from the US Navy, but none were acquired before 1939. Also, in 1931 the US Army worked on a mobile anti-aircraft machine mount on the back of a heavy truck having four .30 caliber water-cooled machine guns and an optical director. It proved unsuccessful and was abandoned.
How many rounds did this cannon fire per second?
A:
125
