Passage: Five-time world champion Sébastien Ogier was the fastest man to finish the day other than the defending rally winner Ott Tänak, who set five out of six fastest stage times and built a 12.3-second lead over the Frenchman, while championship leader Thierry Neuville was another 15.1 seconds behind. Elfyn Evans climbed up three places in the afternoon loop and edged Jari-Matti Latvala by a second. Dani Sordo completed the day in sixth, only one-tenth of a second ahead of Esapekka Lappi, who failed to come to terms with dirt dragged onto the roads by the early starters. Craig Breen lost some time due to being caught in a heavy rain shower in the early stage in the eighth place, followed by Andreas Mikkelsen, who was struggling with his i20's handling and chose to change his driving style, in ninth, only one second behind. Teemu Suninen, driving a third Fiesta, in tenth. Lacking of power caused Mads Østberg to fail to find the pace like Finland, which made him cleared the day off the leaderboard in eleventh overall.

question:
Passage: Sylvester began his study of mathematics at St John's College, Cambridge in 1831, where his tutor was John Hymers. Although his studies were interrupted for almost two years due to a prolonged illness, he nevertheless ranked second in Cambridge's famous mathematical examination, the tripos, for which he sat in 1837. However, Sylvester was not issued a degree, because graduates at that time were required to state their acceptance of the Thirty-Nine Articles of the Church of England, and Sylvester could not do so because he was Jewish. For the same reason, he was unable to compete for a Fellowship or obtain a Smith's prize. In 1838, Sylvester became professor of natural philosophy at University College London and in 1839 a Fellow of the Royal Society of London. In 1841, he was awarded a BA and an MA by the University of Dublin (Trinity College). In the same year he moved to the United States to become a professor of mathematics at the University of Virginia, but left after less than four months following a violent encounter with two students he had disciplined. He moved to New York City and began friendships with the Harvard mathematician Benjamin Peirce (father of Charles Sanders Peirce) and the Princeton physicist Joseph Henry. However, he left in November 1843 after being denied appointment as Professor of Mathematics at Columbia College (now University), again for his Judaism, and returned to England.
