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.

Ex Output:
The earliest form of drama we know about is from the Roman and what other culture?

Passage: The Quran describes itself as "the discernment" (al-furqān), "the mother book" (umm al-kitāb), "the guide" (huda), "the wisdom" (hikmah), "the remembrance" (dhikr) and "the revelation" (tanzīl; something sent down, signifying the descent of an object from a higher place to lower place). Another term is al-kitāb (The Book), though it is also used in the Arabic language for other scriptures, such as the Torah and the Gospels. The adjective of "Quran" has multiple transliterations including "quranic", "koranic", and "qur'anic", or capitalised as "Qur'anic", "Koranic", and "Quranic". The term mus'haf ('written work') is often used to refer to particular Quranic manuscripts but is also used in the Quran to identify earlier revealed books. Other transliterations of "Quran" include "al-Coran", "Coran", "Kuran", and "al-Qurʼan".

Ex Output:
Which term meaning "the mother book" doesn't the Quran apply to itself?

Passage: Memories and lessons from the war are still a major factor in American politics. One side views the war as a necessary part of the Containment policy, which allowed the enemy to choose the time and place of warfare. Others note the U.S. made major strategic gains as the Communists were defeated in Indonesia, and by 1972 both Moscow and Beijing were competing for American support, at the expense of their allies in Hanoi. Critics see the conflict as a "quagmire"—an endless waste of American blood and treasure in a conflict that did not concern US interests. Fears of another quagmire have been major factors in foreign policy debates ever since. The draft became extremely unpopular, and President Nixon ended it in 1973, forcing the military (the Army especially) to rely entirely upon volunteers. That raised the issue of how well the professional military reflected overall American society and values; the soldiers typically took the position that their service represented the highest and best American values.

Ex Output:

 The Vietnam War was an element of what UK diplomatic policy?
