Question: Did the USS Stribling visit Hawaii before making her way to Japan? Passage:On 30 January 1969, Stribling put to sea from Mayport, Florida, to make her second voyage to the Far East. Heading via the Panama Canal, San Diego, and Pearl Harbor, the destroyer made for Yokosuka, Japan, and then operations off the coast of Vietnam. Stribling participated in "Sea Dragon" and "Market Time" operations, and her duties also included bombardments on the gunline, search and rescue missions usually for downed carrier pilots, and Positive Identification Radar Advisory Zone (PIRAZ) duty. The latter assignment involved riding "shotgun" for larger PIRAZ ships armed with more sophisticated radar and target designation systems. That summer, Stribling plane-guarded for the carriers operating on "Yankee Station" in the Gulf of Tonkin. When not operating in the combat zone, she put into Kaohsiung, Taiwan; Hong Kong; and Subic Bay in the Philippines for repairs after a collision with a barge being towed by RVN tug during a nighttime underway replenishment . On 2 August 1969, Stribling cleared the combat zone to return home. On her way, she stopped at Kure and Yokosuka, Japan; Pearl Harbor; San Diego; Acapulco Mexico, and Panama. On 17 September 1969, she reentered Mayport.

Question: In what city is the university located from which Marjorie Grene gave another account of the philosophy of biology? Passage:While the overwhelming majority of English-speaking scholars operating under the banner of "philosophy of biology" work within the Anglo-American tradition of analytical philosophy, there is a stream of philosophic work in continental philosophy which seeks to deal with issues deriving from biological science. The communication difficulties involved between these two traditions are well known, not helped by differences in language. Gerhard Vollmer is often thought of as a bridge but, despite his education and residence in Germany, he largely works in the Anglo-American tradition, particularly pragmatism, and is famous for his development of Konrad Lorenz's and Willard Van Orman Quine's idea of evolutionary epistemology. On the other hand, one scholar who has attempted to give a more continental account of the philosophy of biology is Hans Jonas. His "The Phenomenon of Life" (New York, 1966) sets out boldly to offer an "existential interpretation of biological facts", starting with the organism's response to stimulus and ending with man confronting the Universe, and drawing upon a detailed reading of phenomenology. This is unlikely to have much influence on mainstream philosophy of biology, but indicates, as does Vollmer's work, the current powerful influence of biological thought on philosophy. Another account is given by the late Virginia Tech philosopher Marjorie Grene.

Question: How old was the last Prince of Morgannwg when he died? Passage:Jenkins was born in Merthyr Tydfil, Glamorgan on 30 January 1828. His father, William David Jenkins, could allegedly trace his ancestry back to Iestyn ap Gwrgant, the last Prince of Morgannwg. After attending Taliesin Williams's school in Merthyr Tydfil and Cowbridge Grammar School, Jenkins studied at Oxford University, matriculating at Jesus College in 1846 with the benefit of the Sir Leoline Jenkins scholarship. He studied Literae Humaniores, obtaining a third-class BA degree in 1850. He subsequently obtained further degrees: M.A. in 1852, BD in 1859 and DD in 1871. He became a good classical and oriental scholar whilst at Oxford, developing a fluency in modern languages in later life. Whilst an undergraduate, he tried and failed on several occasions for the Pusey and Ellerton Hebrew Scholarship; after his final failure, Dr Pusey presented him with some books to acknowledge his abilities in Hebrew.
