The 68020-powered Macintosh LC, in its distinctive "pizza box" case, offered color graphics and was accompanied by a new, low-cost 512×384 pixel monitor.

QUES: According to the Sunni scholar Ibn ʻAsākir in the 12th century, there were opportunities for female education in the medieval Islamic world, writing that women could study, earn ijazahs (academic degrees), and qualify as scholars and teachers.

The 'OtherOS' functionality was not present in the updated PS Slim models, and the feature was subsequently removed from previous versions of the PS3 as part of the machine's firmware update version 3.21 which was released on April 1, 2010; Sony cited security concerns as the rationale. The firmware update 3.21 was mandatory for access to the PlayStation Network. The removal caused some controversy; as the update removed officially advertised features from already sold products, and gave rise to several class action lawsuits aimed at making Sony return the feature or provide compensation.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What legal action did some happy OtherOS users take against Sony?
Ah, so.. unanswerable

Problem: 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.
