Problem: By 1975 the majority of local authorities in England and Wales had abandoned the 11-plus examination and moved to a comprehensive system. Over that 10-year period many secondary modern schools and grammar schools were amalgamated to form large neighbourhood comprehensives, whilst a number of new schools were built to accommodate a growing school population. By the mid-1970s the system had been almost fully implemented, with virtually no secondary modern schools remaining. Many grammar schools were either closed or changed to comprehensive status. Some local authorities, including Sandwell and Dudley in the West Midlands, changed all of its state secondary schools to comprehensive schools during the 1970s.
Grammar schools that did not close were converted to what?
The answer is the following: comprehensive schools

Problem: Television has played a major role in the history of the Premier League.

What was the cause of this?
The answer is the following:
a combination of Sky's strategy, the quality of Premier League football and the public's appetite for the game
