Question: Which of the actors playing Qatermass and Paterson was younger? Passage 1:Born in Philadelphia, Day studied at the Jacobs School of Music at Indiana University and at the Curtis Institute of Music where she was a pupil of Margaret Harshaw. She placed third in the finals of the Metropolitan Opera National Council Auditions in 1973, which led to her debut performance at the Metropolitan Opera House on March 25, 1973 singing "Come scoglio" from Così fan tutte and "Song to the Moon" from Rusalka. She made her professional opera debut in 1972 with the Pennsylvania Opera Company as Violetta in La traviata. That same year she was the soprano soloist in Verdi's Requiem with the Mendelssohn Club. In 1973 she portrayed Mimi in La bohème and Violetta with the Little Lyric Opera Company in Philadelphia. In 1974 she made her debut with the Philadelphia Lyric Opera Company as Nella in Gianni Schicchi.
 Passage 2:Actor Jason Flemyng was cast as Quatermass, with long-time Kneale admirer Mark Gatiss as Paterson, Andrew Tiernan as Carroon, Indira Varma as his wife Judith, David Tennant as Briscoe, Adrian Bower as Fullalove and Adrian Dunbar as Lomax—now a Ministry of Defence official rather than a policeman. Isla Blair was cast as Home Secretary Margaret Blaker, a combination of parts of Lomax's character and two officials from the original serial, and she brought to rehearsals a photograph of her husband Julian Glover on the set of the 1967 film version of Quatermass and the Pit. Blair stated that she was delighted to be joining "the Quatermass club".
 Passage 3:The conflict emerged from the First Indochina War against the communist-led Viet Minh. Most of the funding for the French war effort was provided by the U.S. After the French quit Indochina in 1954, the US assumed financial and military support for the South Vietnamese state. The Việt Cộng, also known as or NLF (the National Liberation Front), a South Vietnamese common front under the direction of North Vietnam, initiated a guerrilla war in the south. North Vietnam had also invaded Laos in the mid-1950s in support of insurgents, establishing the Ho Chi Minh Trail to supply and reinforce the Việt Cộng. U.S. involvement escalated under President John F. Kennedy through the MAAG program from just under a thousand military advisors in 1959 to 16,000 in 1963. By 1963, the North Vietnamese had sent 40,000 soldiers to fight in South Vietnam. North Vietnam was heavily backed by the USSR and the People's Republic of China. China also sent hundreds of PLA servicemen to North Vietnam to serve in air-defense and support roles.

Question: What was the lithography previous to 45 nm? Passage 1:In 2000, Parrish was featured in Disney's live-action television film based on the Pinocchio story, Geppetto, portraying the role of Natalie. She then went on to appear as Vanessa in The WB's short-lived sitcom The O'Keefes. Parrish also appeared in shows and made-for-television films on the Disney Channel, and also guest starred in Fox's sitcom The Bernie Mac Show, Nickelodeon's children's comedy-drama series Zoey 101, and Fox's teen drama series The O.C.. Parrish then portrayed Bratz member Jade in the 2007 live-action film Bratz. The role was her first in a motion picture, as well as her first starring role. In May 2007, shortly before the release of Bratz, she was signed to the William Morris Agency. She then landed a recurring role in the NBC supernatural drama series Heroes.
 Passage 2:Somuncu Baba is one of the virtuous men who came to Anadolu for spiritual conquest, he was also a descendant of Islamic prophet Muhammad After receiving an education in cities which are the center of knowledge like Şam, Tabriz, Erdebil, he settled in Bursa for his guidance and duty. He taught at the Bursa Grand Mosque where he was installed by Sultan Bayezid I after it was completed. For hiding his spiritual side, he baked bread and sold them so he was known as Somuncu Baba. He became known after he had translated the sura of Al-Fatiha, in seven different ways during the opening of Bursa Grand Mosque, in Bursa. He avoided becoming famous so he left Bursa and moved Aksaray. He left his son Yusuf Hakiki Baba in Aksaray and he went to Mecca with his son Halil Taybi when they got back to Anadolu they settled in Darende and he died here in 1412. His tomb is still in Darende.
 Passage 3:The Intel Core microarchitecture (previously known as the Next-Generation Micro-Architecture) is a multi-core processor microarchitecture unveiled by Intel in Q1 2006. It is based on the Yonah processor design and can be considered an iteration of the P6 microarchitecture introduced in 1995 with Pentium Pro. High power consumption and heat intensity, the resulting inability to effectively increase clock speed, and other shortcomings such as an inefficient pipeline were the primary reasons why Intel abandoned the NetBurst microarchitecture and switched to a completely different architectural design, delivering high efficiency through a small pipeline rather than high clock speeds. The Core microarchitecture initially did not reached the clock speeds of the NetBurst microarchitecture, even after moving to 45 nm lithography. However after many generations of successor microarchitectures which used Core as their basis (such as Nehalem, Sandy Bridge and more), Intel managed to eventually surpass the clock speeds of Netburst with the Devil's Canyon (Improved version of Haswell) microarchitecture reaching a base frequency of 4 GHz and a maximum tested frequency of 4.4 GHz using 22 nm lithography.

Question: How long had Arthur's father's place of employment existed when Arthur was born? Passage 1:Arthur Aloysius O'Leary was born on September 27, 1887, in Washington, D.C. His father was a worker on the Baltimore and Ohio Railroad. He was educated at Gonzaga College, and his parish was the adjacent St. Aloysius Church. He entered the Society of Jesus on August 14, 1903, and was sent to St. Andrew-on-Hudson in New York for his scholasticate. He then completed his studies at Woodstock College in Maryland, where he earned a Doctor of Philosophy. He went to Georgetown University in 1912, as a professor of philosophy, holding the position until 1916. At the same time, he was also spiritual director for the university. He was finally ordained a priest in 1919, becoming a member of the first class of priests ordained at Georgetown. He then returned to St. Andrew-on-Hudson, where he taught for several years.
 Passage 2:Vicelinus was called to Bremen to act as teacher and principal of the school, and was offered a canonry by Archbishop Frederick of the Archbishopric of Hamburg-Bremen. In 1122 he may have gone to Laon to complete his studies under Abelard. In 1126, Vicelinus decided to travel to Madgeburg, in order to see St. Norbert, who at that time was the archbishop. He hoped that St. Norbert would ordain him a priest and he could begin missionary work among the Slavs. For one reason or another this plan failed and so Vicelinus returned to Bremen, where Bishop Albero ordained him. Hamburg-Bremen's Archbishop Adalbero sent him among the Polabian Slavs, and in the fall of 1126 Henry, Prince of the Obotrites, gave him a church in Liubice, near the site of the later Lübeck. At the death of Henry (22 March 1127) Vicelinus returned to Bremen, and was appointed pastor at Wippenthorp. This gave him an opportunity to work among the Wagrians and neighbouring Obotrites.
 Passage 3:Howard was born to Ossian Gregory Howard, a lawyer, and Lucy Denham Thurber on 11 June 1857. His relatives from his mother's side included the Harvard astronomer E.C. Pickering while other distant relatives included Senator J.M. Howard and President William Howard Taft. Shortly after his birth, the family moved from Rockford, to Ithaca, New York where his father worked with a law firm. Howard attended Ithaca Academy. An interest in insect collecting encouraged by his parents with the gift of The Butterfly Hunters by Mary Treat at the age of 10 followed by more books and at the age of 13, along with another collector friend, recorded the introduction of the European cabbage butterfly (Pieris rapae) in the Catskill region. Along with his friends, he founded the Ithaca Natural History Society to meet and discuss papers and insects. While out collecting one day, he met John Henry Comstock, who invited him to his lab at Cornell University. Howard enrolled in Cornell in September 1873, three years after the death of his father, and following the advice of his mother's friends, went to study civil engineering. Doing poorly in differential calculus made him drop engineering and he began to study other subjects including French, German, and Italian. He then joined Comstock's lab as the first research student and graduated in June 1877 with a thesis on respiration in the larva of Corydalis cornutus. He worked with Burt Green Wilder and Simon Henry Gage and received a masters at Cornell. In the 1880s, he also attended Columbian College (now George Washington University) for medicine, although he didn't complete it. He however received an honorary MD from the same university in 1911 for his contribution to medical entomology.
