Input: Read this: Colin Humphreys and W. G. Waddington of Oxford University considered the possibility that a lunar, rather than solar, eclipse might have taken place. They concluded that such an eclipse would have been visible, for thirty minutes, from Jerusalem and suggested the gospel reference to a solar eclipse was the result of a scribe wrongly amending a text. Historian David Henige dismisses this explanation as 'indefensible' and astronomer Bradley Schaefer points out that the lunar eclipse would not have been visible during daylight hours.
Question: What city was Henige originally from?

Input: Read this: As early as 1794, Lieutenant-Governor of New South Wales Francis Grose suggested its closure as a penal settlement, as it was too remote and difficult for shipping and too costly to maintain. The first group of people left in February 1805, and by 1808 only about 200 remained, forming a small settlement until the remnants were removed in 1813. A small party remained to slaughter stock and destroy all buildings, so that there would be no inducement for anyone, especially from other European powers, to visit and lay claim to the place. From 15 February 1814 to 6 June 1825 the island was abandoned.
Question: When did Lieutenant-Governor of New South Wales Francis Grose start suggesting Norfolk Island be closed as a penal settlement?

Input: Read this: European colonialism in the Sahara began in the 19th century. France conquered the regency of Algiers from the Ottomans in 1830, and French rule spread south from Algeria and eastwards from Senegal into the upper Niger to include present-day Algeria, Chad, Mali then French Sudan including Timbuktu, Mauritania, Morocco (1912), Niger, and Tunisia (1881). By the beginning of the 20th century, the trans-Saharan trade had clearly declined because goods were moved through more modern and efficient means, such as airplanes, rather than across the desert.
