Input: Elevator
Some types of residential elevators do not use a traditional elevator shaft, machine room, and elevator hoistway. This allows an elevator to be installed where a traditional elevator may not fit, and simplifies installation. The ASME board first approved machine-room-less systems in a revision of the ASME A17.1 in 2007. Machine-room-less elevators have been available commercially since the mid 1990s, however cost and overall size prevented their adoption to the residential elevator market until around 2010.

This decision reflected a revision of what?
Output: the ASME A17.1

Input: Presbyterianism
In 1972, the Presbyterian Church of England (PCofE) united with the Congregational Church in England and Wales to form the United Reformed Church (URC). Among the congregations the PCofE brought to the URC were Tunley (Lancashire), Aston Tirrold (Oxfordshire) and John Knox Presbyterian Church, Stepney, London (now part of Stepney Meeting House URC) these are among the sole survivors today of the English Presbyterian churches of the 17th century. The URC also has a presence in Scotland, mostly of former Congregationalist Churches. Two former Presbyterian congregations, St Columba's, Cambridge (founded in 1879), and St Columba's, Oxford (founded as a chaplaincy by the PCofE and the Church of Scotland in 1908 and as a congregation of the PCofE in 1929), continue as congregations of the URC and university chaplaincies of the Church of Scotland.

What are the two former Presbyterian congregations in England?
Output: St Columba's, Cambridge (founded in 1879), and St Columba's, Oxford

Input: LaserDisc
Apple's HyperCard scripting language provided Macintosh computer users with a means to design databases of slides, animation, video and sounds from LaserDiscs and then to create interfaces for users to play specific content from the disc through software called LaserStacks. User-created "stacks" were shared and were especially popular in education where teacher-generated stacks were used to access discs ranging from art collections to basic biological processes. Commercially available stacks were also popular with the Voyager company being possibly the most successful distributor.

Which commercial company was LaserStack's most successful distributor?
Output: Voyager
