Passage: As far as we know, the earliest cantatas of Johann Sebastian Bach were performed in Mühlhausen from 1706 to 1708. He was employed as an organist there, but he occasionally composed cantatas, mostly for special occasions. The cantatas were based mainly on biblical texts and hymns, such as Aus der Tiefen rufe ich, Herr, zu dir, BWV 131 (a psalm setting), and the Easter chorale cantata Christ lag in Todes Banden, BWV 4.
Bach was next appointed organist and chamber musician in Weimar on 25 June 1708 at the court of the co-reigning dukes in Saxe-Weimar, Wilhelm Ernst and his nephew Ernst August. He initially concentrated on the organ, composing major works for the instrument, including the Orgelbüchlein, the Toccata and Fugue in D minor, BWV 565, and the Prelude and Fugue in E major, BWV 566. He was promoted to Konzertmeister on 2 March 1714, an honour that entailed performing a church cantata monthly in the Schlosskirche. The first cantatas he composed in the new position were Himmelskönig, sei willkommen, BWV 182, for Palm Sunday, Weinen, Klagen, Sorgen, Zagen, BWV 12 for Jubilate Sunday, and Erschallet, ihr Lieder, BWV 172, for Pentecost. Mostly inspired by texts by the court poet, Salomo Franck, they contain recitatives and arias. When Johann Samuel Drese, the Kapellmeister (director of music), died in 1716, Bach hoped in vain to become his successor. Bach looked for a better position and found it as Kapellmeister at the court of Leopold, Prince of Anhalt-Köthen. However, the duke in Weimar did not dismiss him and arrested him for disobedience. He was released on 2 December 1717.In Köthen, Bach found an employer who was an enthusiastic musician himself. The court was Calvinist, therefore Bach's work from this period was mostly secular, including the orchestral suites, the cello suites, the sonatas and partitas for solo violin, and the Brandenburg Concertos. He composed secular cantatas for the court for occasions such as New Year's Day and the prince's birthday, including Die Zeit, die Tag und Jahre macht, BWV 134a. He later parodied some of them as church cantatas without major changes, for example Ein Herz, das seinen Jesum lebend weiß, BWV 134. 
Question: What is the last name of the person who parodied some secular cantatas as church cantatas without major changes, for example Ein Herz, das seinen Jesum lebend weiß, BWV 134?

Ex Output:
Bach.

Passage: The second major American company to set up a manufacturing base in Trafford Park was the Ford Motor Company, in 1911. Initially Ford used its factory as an assembly plant for the Model T, although other vehicles were assembled there in later years, before moving to a new factory at Dagenham, Essex, in 1931. By 1915, 100 American companies had moved into the park, peaking at more than 200 by 1933. When the cotton industry began to decline in the early 20th century, Trafford Park and the Manchester Ship Canal helped Manchester – and to a lesser extent the rest of south Lancashire – to weather the economic depression from which the rest of Lancashire suffered. During the First World War the park was used for the manufacture of munitions, chemicals and other materiel. Most firms at Trafford Park succeeded in avoiding bankruptcy during the Great Depression, unlike the rest of Lancashire. Ford moved to Dagenham in 1931, but returned temporarily to Trafford Park during the Second World War.Metropolitan Vickers set up Manchester's and one of the UK's first radio stations at their factory in 1921. The station's first broadcast took place on 17 May 1922. In October that year the company was one of six who formed the British Broadcasting Company (BBC), which started broadcasting from the Metrovicks studio under the call sign 2ZY on 15 November 1922. Much of the station's content was musical, but news, plays, and children's programmes were also transmitted. Conditions in the small 30-by-16-foot (9.1 m × 4.9 m) studio were cramped, and the BBC moved the station to larger premises outside the park in 1923. 
Question: Where had 100 American companies moved to by 1915?

Ex Output:

Trafford Park.
