Question: On 1 February 1908, the king Dom Carlos I of Portugal and his heir apparent, Prince Royal Dom Luis Filipe, Duke of Braganza, were murdered in Lisbon. Under his rule, Portugal had twice been declared bankrupt on 14 June 1892, and again on 10 May 1902 causing social turmoil, economic disturbances, protests, revolts and criticism of the monarchy. Manuel II of Portugal became the new king, but was eventually overthrown by the 5 October 1910 revolution, which abolished the regime and instated republicanism in Portugal. Political instability and economic weaknesses were fertile ground for chaos and unrest during the Portuguese First Republic. These conditions would lead to the failed Monarchy of the North, 28 May 1926 coup d'etat, and the creation of the National Dictatorship (Ditadura Nacional).
Is there an answer to this question: On what day was King Manuel II overthrown?

Answer: 5 October 1910

Question: Following the 197475 Loans Affair, the Malcolm Fraser led Liberal-Country Party Coalition argued that the Whitlam Government was incompetent and delayed passage of the Government's money bills in the Senate, until the government would promise a new election. Whitlam refused, Fraser insisted leading to the divisive 1975 Australian constitutional crisis. The deadlock came to an end when the Whitlam government was dismissed by the Governor-General, Sir John Kerr on 11 November 1975 and Fraser was installed as caretaker Prime Minister, pending an election. Fraser won in a landslide at the resulting 1975 election.
Is there an answer to this question: When was Kerr installed as caretaker Prime Minister?

Question: A January 2013 press release from the USB group revealed plans to update USB 3.0 to 10 Gbit/s. The group ended up creating a new USB version, USB 3.1, which was released on 31 July 2013, introducing a faster transfer mode called SuperSpeed USB 10 Gbit/s, putting it on par with a single first-generation Thunderbolt channel. The new mode's logo features a "Superspeed+" caption (stylized as SUPERSPEED+). The USB 3.1 standard increases the data signaling rate to 10 Gbit/s in the USB 3.1 Gen2 mode, double that of USB 3.0 (referred to as USB 3.1 Gen1) and reduces line encoding overhead to just 3% by changing the encoding scheme to 128b/132b. The first USB 3.1 implementation demonstrated transfer speeds of 7.2 Gbit/s.
Is there an answer to this question: What actually happened whenever USB 3.0 was updated?

Answer: The group ended up creating a new USB version

Question: The effect of these differences was accentuated by the pre-war preparations. The Prussian General Staff had drawn up minutely detailed mobilization plans using the railway system, which in turn had been partly laid out in response to recommendations of a Railway Section within the General Staff. The French railway system, with multiple competing companies, had developed purely from commercial pressures and many journeys to the front in Alsace and Lorraine involved long diversions and frequent changes between trains. Furthermore, no system had been put in place for military control of the railways, and officers simply commandeered trains as they saw fit. Rail sidings and marshalling yards became choked with loaded wagons, with nobody responsible for unloading them or directing them to the destination.
Is there an answer to this question: What factor especially affected travel to the front in Alsace and Lorraine?

Answer:
frequent changes between trains
