Example Input: Question: Has the the team against which Duda hit three home runs on July 29 ever played in a World Series? Passage:On July 29, during a 7–3 loss to the San Diego Padres, Duda became the eleventh Mets player to hit three home runs in a single game, and only the second Met to do so at home after Kirk Nieuwenhuis had accomplished the feat less than a month before. Duda set a Mets franchise record on August 1 when eight of his consecutive hits came in the form of home runs; he and teammate Noah Syndergaard were named National League Co-Players of the Week for the week ending on August 2. On September 26, Duda hit his first career grand slam in the Mets' 10–2 victory over the Cincinnati Reds. That victory clinched the NL East division title for the New York Mets. On the final day of the season, Duda was hit by a pitch from the Washington Nationals' Tanner Roark, giving him 14 total HBP on the season and breaking the Mets single season record, previously shared by John Olerud and Ron Hunt. For the season, he had the highest fly ball percentage (50.6%), and the lowest ground ball percentage (27.4%), of all major league hitters.

Passage:He was educated in the German Gymnasium, where he learned the classical languages, and trained as an Indo-Europeanist and a historical and comparative linguist in universities in Munich, Zurich, Padua, and Florence.

He was a member of the Linguistic Society of America, of which he was elected President in 1958, and a member of the American Philosophical Society for more than 30 years.
