In this task, you're given a passage, further information available on a particular linked term from the statement, and a question. Your job is to generate the answer to the question by using the information provided. If there is no clear answer obtainable, output 'none'.

Passage: Linda was introduced as the wife of Mick Carter, played by Danny Dyer, the brother of established character Shirley Carter (Linda Henry), who has appeared in EastEnders since 2006. Luisa Bradshaw-White joined the cast as Shirley's sister Tina Carter in early November, and Linda was the second new Carter to appear after her. Kellie Bright's casting was announced alongside Danny Dyer's on 1 October 2013, a week after Bradshaw-White's casting was revealed. Linda was described as having been with Mick since they were teenagers, and despite not being 'blessed with brains', is a 'tough woman who will always fight tooth and nail for her family - especially her children'. Bright previously appeared as a bridesmaid in 1986 at the wedding of Michelle Fowler (Susan Tully) and Lofty Holloway (Tom Watt), and starred in scenes opposite her current co-star Letitia Dean, who continues to appear as Sharon Watts. Bright estimated herself to be aged 10 at the time. She also auditioned for the role of Tanya Branning in 2006, a role that was eventually given to Jo Joyner.

Answer: Susan Tully

Passage: The minesweeper departed Sasebo on 5 January 1966 for an "Operation Market Time" deployment off the coast of Vietnam. On the 9th she paused briefly at Kaohsiung to take on fuel and provisions. She arrived on her station south of Vung Tau on 14 January and patrolled the sea lanes in her area until relieved on 22 February. The minesweeper returned to Sasebo on 5 March to begin one and one-half months of upkeep and training. On 21 April Albatross sailed in company with Epping Forest (MCS-7), Warbler (MSC-206), and Peacock (MSC-198) for Chinhae, Korea and an exercise with the Republic of Korea Navy. Following the five-day exercise, she visited Kure on 29 April before returning to Sasebo on 4 May. Albatross got underway on 20 May for the South China Sea in company with Warbler. Her station was located off the tip of the Camau peninsula, and her patrol lasted through 9 July. Albatross then sailed due south to visit Singapore from 12 to 16 July and made a port call at Hong Kong before among back in Sasebo on 30 July.

Answer: none

Passage: In 1979 Hirschfeld published the first of a trilogy on Galois geometry, pegged at a level depending only on "the group theory and linear algebra taught in a first degree course, as well as a little projective geometry, and a very little algebraic geometry." When q is a prime power then there is a finite field GF(q) with q elements called a Galois field. A vector space over GF(q) of n + 1 dimensions produces an n-dimensional Galois geometry PG(n,q) with its subspaces: one-dimensional subspaces are the points of the Galois geometry and two-dimensional subspaces are the lines. Non-singular linear transformations of the vector space provide motions of PG(n,q). The first book (1979) covered PG(1,q) and PG(2,q). The second book addressed PG(3,q) and the third PG(n,q). Chapters are numbered sequentially through the trilogy: 14 in the first book, 15 to 21 in the second, and 22 to 27 in the third. Finite geometry has contributed to coding theory, such as the Goppa code, so the field is supported by computer science. In the preface of the 1991 text Hirschfeld summarizes the status of Galois geometry, mentioning maximum distance separable code, mathematics journals publishing finite geometry, and conferences on combinatorics featuring Galois geometry. Colleague Joseph A. Thas is coauthor of General Galois Geometries on PG(n,q) where n 4.
Link Information: ystems of linear equations arose in Europe with the introduction in 1637 by Rene Descartes of coordinates in geometry. Question: Of the types of math Hirschfeld in 1979 considered necessary to learn before reading his work on Galois geometry, which is the oldest mathematical discipline?
Answer: algebraic geometry
