Here is a question about this article: The first commutator DC electric motor capable of turning machinery was invented by the British scientist William Sturgeon in 1832. Following Sturgeon's work, a commutator-type direct-current electric motor made with the intention of commercial use was built by the American inventor Thomas Davenport, which he patented in 1837. The motors ran at up to 600 revolutions per minute, and powered machine tools and a printing press. Due to the high cost of primary battery power, the motors were commercially unsuccessful and Davenport went bankrupt. Several inventors followed Sturgeon in the development of DC motors but all encountered the same battery power cost issues. No electricity distribution had been developed at the time. Like Sturgeon's motor, there was no practical commercial market for these motors.
What is the answer to this question: What necessary technical development had yet to occur to make electric motors useful?
****
So... electricity distribution


The problem: Answer a question about this article:
When interviewed for Mojo magazine the band said the most amazing sight at Live Aid was to see the audience clapping to "Radio Ga Ga". Brian May stated: "I'd never seen anything like that in my life and it wasn't calculated either. We understood our audience and played to them but that was one of those weird accidents because of the (music) video. I remember thinking 'oh great, they've picked it up' and then I thought 'this is not a Queen audience'. This is a general audience who've bought tickets before they even knew we were on the bill. And they all did it. How did they know? Nobody told them to do it."
What medium helped Queen fans get used to their songs before Live Aid?
****
The answer: (music) video

Bottom Up Testing is an approach to integrated testing where the lowest level components (modules, procedures, and functions) are tested first, then integrated and used to facilitate the testing of higher level components. After the integration testing of lower level integrated modules, the next level of modules will be formed and can be used for integration testing. The process is repeated until the components at the top of the hierarchy are tested. This approach is helpful only when all or most of the modules of the same development level are ready.[citation needed] This method also helps to determine the levels of software developed and makes it easier to report testing progress in the form of a percentage.[citation needed]

What does Bottom Up Testing also help with once the process has been repeated over and over again at all levels?
Answer: makes it easier to report testing progress in the form of a percentage


Problem: People of German origin are found in various places around the globe. United States is home to approximately 50 million German Americans or one third of the German diaspora, making it the largest centre of German-descended people outside Germany. Brazil is the second largest with 5 million people claiming German ancestry. Other significant centres are Canada, Argentina, South Africa and France each accounting for at least 1 million. While the exact number of German-descended people is difficult to calculate, the available data makes it safe to claim the number is exceeding 100 million people.
How many Germans live in Brazil?
The answer is the following: 5 million


Input: Article: One senator represents the island in the French Senate. The first election was held on 21 September 2008 with the last election in September 2014. St. Barthélemy became an overseas territory of the European Union on 1 January 2012, but the island's inhabitants remain French citizens with EU status holding EU passports. France is responsible for the defence of the island and as such has stationed a security force on the island comprising six policemen and thirteen gendarmes (posted on two-year term).

Now answer this question: How many policemen does the French government pay for on St. Barts?

Output:
thirteen
