Problem: Electric motor:

A major turning point in the development of DC machines took place in 1864, when Antonio Pacinotti described for the first time the ring armature with its symmetrically grouped coils closed upon themselves and connected to the bars of a commutator, the brushes of which delivered practically non-fluctuating current. The first commercially successful DC motors followed the invention by Zénobe Gramme who, in 1871, reinvented Pacinotti's design. In 1873, Gramme showed that his dynamo could be used as a motor, which he demonstrated to great effect at exhibitions in Vienna and Philadelphia by connecting two such DC motors at a distance of up to 2 km away from each other, one as a generator. (See also 1873 : l'expérience décisive [Decisive Workaround] .)

How far from each other were the motors in Gramme's demonstrations?
---
A: 2 km


Problem: In May 2013, Microsoft launched a new television campaign for Windows 8 illustrating the capabilities and pricing of Windows 8 tablets in comparison to the iPad, which featured the voice of Siri remarking on the iPad's limitations in a parody of Apple's "Get a Mac" advertisements. On June 12, 2013 during game 1 of the 2013 Stanley Cup Finals, Microsoft premiered the first ad in its "Windows Everywhere" campaign, which promoted Windows 8, Windows Phone 8, and the company's suite of online services as an interconnected platform.
When was the last game of the 2014 Stanley Cup Finals?

Context and question: Florey and Chain succeeded in purifying the first penicillin, penicillin G, in 1942, but it did not become widely available outside the Allied military before 1945. Later, Norman Heatley developed the back extraction technique for efficiently purifying penicillin in bulk. The chemical structure of penicillin was determined by Dorothy Crowfoot Hodgkin in 1945. Purified penicillin displayed potent antibacterial activity against a wide range of bacteria and had low toxicity in humans. Furthermore, its activity was not inhibited by biological constituents such as pus, unlike the synthetic sulfonamides. The discovery of such a powerful antibiotic was unprecedented, and the development of penicillin led to renewed interest in the search for antibiotic compounds with similar efficacy and safety. For their successful development of penicillin, which Fleming had accidentally discovered but could not develop himself, as a therapeutic drug, Ernst Chain and Howard Florey shared the 1945 Nobel Prize in Medicine with Fleming. Florey credited Dubos with pioneering the approach of deliberately and systematically searching for antibacterial compounds, which had led to the discovery of gramicidin and had revived Florey's research in penicillin.
When did penicillin G become available outside of military use?
Answer: 1945


Question: A year later, at the height of the 1975 Australian constitutional crisis, the Australian Prime Minister, Gough Whitlam, was dismissed from his post by Governor-General Sir John Kerr, after the Opposition-controlled Senate rejected Whitlam's budget proposals. As Whitlam had a majority in the House of Representatives, Speaker Gordon Scholes appealed to the Queen to reverse Kerr's decision. She declined, stating that she would not interfere in decisions reserved by the Constitution of Australia for the governor-general. The crisis fuelled Australian republicanism.
Is there an answer to this question: In what year did Gordon Scholes become Speaker of the House of Representatives in Australia?

Answer: unanswerable

The party was a member of the Labour and Socialist International between 1923 and 1940. Since 1951 the party has been a member of the Socialist International, which was founded thanks to the efforts of the Clement Attlee leadership. However, in February 2013, the Labour Party NEC decided to downgrade participation to observer membership status, "in view of ethical concerns, and to develop international co-operation through new networks". Labour was a founding member of the Progressive Alliance international founded in co-operation with the Social Democratic Party of Germany and other social-democratic parties on 22 May 2013.
What was the party a member of before 1923?
A:
unanswerable
