Problem: Miami:

Miami is the southern terminus of Amtrak's Atlantic Coast services, running two lines, the Silver Meteor and the Silver Star, both terminating in New York City. The Miami Amtrak Station is located in the suburb of Hialeah near the Tri-Rail/Metrorail Station on NW 79 St and NW 38 Ave. Current construction of the Miami Central Station will move all Amtrak operations from its current out-of-the-way location to a centralized location with Metrorail, MIA Mover, Tri-Rail, Miami International Airport, and the Miami Intermodal Center all within the same station closer to Downtown. The station was expected to be completed by 2012, but experienced several delays and was later expected to be completed in late 2014, again pushed back to early 2015.

Along with the Silver Star, what Amtrak line runs to Miami?

A: Silver Meteor

Problem: When a historic document survives only in translation, the original having been lost, researchers sometimes undertake back-translation in an effort to reconstruct the original text. An example involves the novel The Saragossa Manuscript by the Polish aristocrat Jan Potocki (17611815), who wrote the novel in French and anonymously published fragments in 1804 and 181314. Portions of the original French-language manuscript were subsequently lost; however, the missing fragments survived in a Polish translation that was made by Edmund Chojecki in 1847 from a complete French copy, now lost. French-language versions of the complete Saragossa Manuscript have since been produced, based on extant French-language fragments and on French-language versions that have been back-translated from Chojecki's Polish version.
Who was Jan Potocki related to?

On December 15, 2012, several news outlets reported that President Barack Obama would nominate Kerry to succeed Hillary Clinton as Secretary of State, after Susan Rice, widely seen as Obama's preferred choice, withdrew her name from consideration citing a politicized confirmation process following criticism of her response to the 2012 Benghazi attack. On December 21, Obama proposed the nomination which received positive commentary. His confirmation hearing took place on January 24, 2013, before the Senate Foreign Relations Committee, the same panel where he first testified in 1971. The committee unanimously voted to approve him on January 29, 2013, and the same day the full Senate confirmed him on a vote of 943. In a letter to Massachusetts Governor Deval Patrick, Kerry announced his resignation from the Senate effective February 1.
Why did Rice withdraw?
A: a politicized confirmation process following criticism of her response to the 2012 Benghazi attack

Question: The Roman Catholic Church celebrates his feast day not on the date of his death, June 3, as is usual, nor even on the day of his papal inauguration (as is sometimes done with Popes who are Saints, such as with John Paul II) but on 11 October, the day of the first session of the Second Vatican Council. This is understandable, since he was the one who had had the idea for it and had convened it. On Thursday, 11 September 2014, Pope Francis added his optional memorial to the worldwide General Roman Calendar of saints' feast days, in response to global requests. He is commemorated on the date of his death, 3 June, by the Evangelical Lutheran Church in America and on the following day, 4 June, by the Anglican Church of Canada and the Episcopal Church (United States).
Is there an answer to this question: When is his feast day celebrated?

Answer: 11 October

Romila Thapar notes that the division into Hindu-Muslim-British periods of Indian history gives too much weight to "ruling dynasties and foreign invasions", neglecting the social-economic history which often showed a strong continuity. The division into Ancient-Medieval-Modern periods overlooks the fact that the Muslim conquests occurred gradually during which time many things came and went off, while the south was never completely conquered. According to Thapar, a periodisation could also be based on "significant social and economic changes", which are not strictly related to a change of ruling powers.[note 1]
What type of history period is often neglected in Indian histories?
A:
social-economic
