Question: On what date did Recitation win its maiden race at Newbury Racecourse? Passage:After finishing third over five furlongs on his racecourse debut, Recitation won a maiden race over the same distance at Newbury Racecourse, beating I'll See You by half a length. The colt was then moved up sharply in class for the Group Three Coventry Stakes over six furlongs at Royal Ascot in June in which he was ridden by Greville Starkey and started at odds of 11/1. In a performance which Timeform described as "a revelation", Recitation took the lead a quarter mile from the finish and drew clear of the field to win easily by five lengths from Motavato, Bel Bolide and Another Realm. The form of the race was subsequently boosted when the third and fourth placed horses won the Gimcrack Stakes and the Richmond Stakes respectively. In the July Stakes at Newmarket Racecourse Recitation started 2/5 favourite against two opponents, but was beaten two and a half lengths by Age Quod Agis.

Question: How wide is the body of water that separates the Eurasian and North American continents? Passage:The Russian Empire began its interest of the Pacific Northwest in the 18th century, initially curious if there was a land connection between the Eurasian and North American Continents. Two expeditions were led by Vitus Bering, with the findings proving the separation of two continents through the Bering Sea. Being the first European nation to chart much of what comprises the modern American state of Alaska, many locations retain Russian place names. The discovery of sizable fur bearing populations by Bering drew the attention of promyshlenniki previously engaged in the Siberian fur trade. Based out of the Siberian ports of Okhotsk or Petropavlovsk, fur trappers sailed and reported the location of land formations like the Aleutian Islands, Kodiak Island and portions of the Alaskan mainland. Relations with Native Alaskans was often terse due to the uncontrolled actions of particular promyshlenniki who killed and raped Indigenous on islands they trapped furs.

Question: How many years did the Batavian Revolution take place? Passage:In 1795 Fijnje returned to the Netherlands (after the Batavian Revolution), after which he became a member of the commité van waakzaamheid (the Batavian version of the French Committee of Public Safety), chaired the Provisional Representatives of the People of Holland for a while. and - together with Samuel Iperusz Wiselius and professor Theodorus van Kooten - served on the committee for the liquidation of the VOC. In all these posts he took radical viewpoints, but he also enjoyed himself thoroughly. On 22 January 1798, he performed a Coup d'état with general Herman Willem Daendels, Pieter Vreede and Van Langen to guarantee "the unity and indivisibility" of the Batavian republic. The radical and omnipresent Fijnje represented the Uitvoerend Bewind and founded the "Binnenlandse Bataafse Courant" (Interior Batavian Courier). The controversial unitarissen did not long remain in power, for on 12 June 1798 general Daendels led another coup, this time putting the "moderates" in power in the Uitvoerend Bewind. For the corrupt former exiles with explicit opinions, whether democrat or aristocrat, there was no longer any place. Fijnje and Van Langen were locked up until the end of the year in the Gevangenpoort, accused of embezzling state money by the public prosecutor Van Maanen, but never put on trial.
