[Q]: Passage: Greek drama exemplifies the earliest form of drama of which we have substantial knowledge. Tragedy, as a dramatic genre, developed as a performance associated with religious and civic festivals, typically enacting or developing upon well-known historical or mythological themes. Tragedies generally presented very serious themes. With the advent of newer technologies, scripts written for non-stage media have been added to this form. War of the Worlds (radio) in 1938 saw the advent of literature written for radio broadcast, and many works of Drama have been adapted for film or television. Conversely, television, film, and radio literature have been adapted to printed or electronic media.
[A]: The earliest form of drama we know about is from the Roman and what other culture?


[Q]: Passage: In July 1977, General Zia-ul-Haq overthrew Prime Minister Zulfiqar Ali Bhutto's regime in Pakistan. Ali Bhutto, a leftist in democratic competition with Islamists, had announced banning alcohol and nightclubs within six months, shortly before he was overthrown. Zia-ul-Haq was much more committed to Islamism, and "Islamization" or implementation of Islamic law, became a cornerstone of his eleven-year military dictatorship and Islamism became his "official state ideology". Zia ul Haq was an admirer of Mawdudi and Mawdudi's party Jamaat-e-Islami became the "regime's ideological and political arm". In Pakistan this Islamization from above was "probably" more complete "than under any other regime except those in Iran and Sudan," but Zia-ul-Haq was also criticized by many Islamists for imposing "symbols" rather than substance, and using Islamization to legitimize his means of seizing power. Unlike neighboring Iran, Zia-ul-Haq's policies were intended to "avoid revolutionary excess", and not to strain relations with his American and Persian Gulf state allies. Zia-ul-Haq was killed in 1988 but Islamization remains an important element in Pakistani society.
[A]: When was the regime in Pakistan accepted by General Zia-ul-Haq?
