Input: Article: Through the 1960s, 1970s, and 1980s, various methods to improve the dynamic range of mass-produced records involved highly advanced disc cutting equipment. These techniques, marketed, to name two, as the CBS DisComputer and Teldec Direct Metal Mastering, were used to reduce inner-groove distortion. RCA Victor introduced another system to reduce dynamic range and achieve a groove with less surface noise under the commercial name of Dynagroove. Two main elements were combined: another disk material with less surface noise in the groove and dynamic compression for masking background noise. Sometimes this was called "diaphragming" the source material and not favoured by some music lovers for its unnatural side effects. Both elements were reflected in the brandname of Dynagroove, described elsewhere in more detail. It also used the earlier advanced method of forward-looking control on groove spacing with respect to volume of sound and position on the disk. Lower recorded volume used closer spacing; higher recorded volume used wider spacing, especially with lower frequencies. Also, the higher track density at lower volumes enabled disk recordings to end farther away from the disk center than usual, helping to reduce endtrack distortion even further.

Now answer this question: What technique were used to reduce inner-groove distortion?

Output: CBS DisComputer and Teldec Direct Metal Mastering

Input: Article: In 1899, the local postage stamps were overprinted "Guam" as was done for the other former Spanish colonies, but this was discontinued shortly thereafter and regular U.S. postage stamps have been used ever since. Because Guam is also part of the U.S. Postal System (postal abbreviation: GU, ZIP code range: 9691096932), mail to Guam from the U.S. mainland is considered domestic and no additional charges are required. Private shipping companies, such as FedEx, UPS, and DHL, however, have no obligation to do so, and do not regard Guam as domestic.

Now answer this question: What is the current Zip Code range in Guam?

Output: 9691096932

Input: Article: Terry Neill was recruited by the Arsenal board to replace Bertie Mee on 9 July 1976 and at the age of 34 he became the youngest Arsenal manager to date. With new signings like Malcolm Macdonald and Pat Jennings, and a crop of talent in the side such as Liam Brady and Frank Stapleton, the club enjoyed their best form since the 1971 double, reaching a trio of FA Cup finals (1978, 1979 and 1980), and losing the 1980 European Cup Winners' Cup Final on penalties. The club's only success during this time was a last-minute 32 victory over Manchester United in the 1979 FA Cup Final, widely regarded as a classic.

Now answer this question: On what date was Bertie Mee replaced by Arsenal?

Output:
9 July 1976
