Question: Of the 8 fraternities at the University of Alabama in the 1800s, which was the oldest on a national level? Passage:Greek letter organizations (GLOs) first appeared at the university in 1847 when two men visiting from Yale University installed a chapter of Delta Kappa Epsilon. When DKE members began holding secret meetings in the old state capitol building that year, the administration strongly voiced its disapproval. Over a few more decades, 7 other fraternities appeared at UA: Alpha Delta Phi in 1850, Phi Gamma Delta in 1855, Sigma Alpha Epsilon in 1856 (this was the founding chapter), Kappa Sigma in 1867, Sigma Nu in 1874, Sigma Chi in 1876, and Phi Delta Theta in 1877. Anti-fraternity laws were imposed that year, but were lifted in the 1890s. Women at the university founded the Zeta chapter of Kappa Delta sorority in 1903. Alpha Delta Pi soon followed.

Question: Which city that the Montgomery Canal ran through after an extension has the largest population? Passage:In the Middle Ages Cilthriew was one of the townships in Kerry. The township is also referred to as Kilroith or Kilroyth. Richard Williams makes the claim that Cilthriew and the neighbouring house of Brynllywarch (which was also a township) were in the ownership of the Pugh (ap Hugh) family from at least 1500. A William Pugh of Kilroith is mentioned in 1632, when he purchased from Ann Foxe, widow of Somerset Foxe lands in Kilroith including Maes y Deynant William Pugh of ‘‘Kilthrew’’ was the Sheriff of Montgomeryshire in 1767 and his son William, who was also Sheriff of Montgomeryshire in 1813, became a very successful attorney and purchased the Caer Howell estate in Montgomery. His son was the notable William Pugh, an entrepreneur, who did much to develop trade and infrastructure in the Montgomeryshire Severn valley. He paid for the final extension of the Montgomery Canal from Berriew to Newtown, and for various road building schemes including a road from Abermule along the Mule valley. In Newtown he encouraged the growth of the textile industry and was responsible for the Flannel exchange, designed by Thomas Penson. In 1828 he sold the Caer Howell estate, using the proceeds to develop Brynllywarch. For this work he may have employed T G Newnham and J W Poundley as his architects and surveyors. His schemes were over ambitious and in June 1835 he fled to Caen in Normandy to escape his creditors. This resulted in the Brynllywarch and Cilthriew estates, which then consisted of 27 farms, being sold in 1839 to Richard Leyland (Bullin), a very wealthy banker from Liverpool. Leyland was to give these estates, together with the Leighton Hall Estates to his nephew John Naylor in 1846. The very detailed survey of the estates purchased by Leyland and later John Naylor, drawn up by J W Poundley, is now in the National Library of Wales. John Naylor died on13th July 1889 and the estates continued in the Naylor family ownership until about 1930, when the various farms including Cilthriew were sold.
