Whatemerged in the middle east after ww1, Context: After World War I, when Britain and France divided up the Middle East's countries, apart from Turkey, between them, pursuant to the Sykes-Picot agreementin violation of solemn wartime promises of postwar Arab autonomythere came an immediate reaction: the Muslim Brotherhood emerged in Egypt, the House of Saud took over the Hijaz, and regimes led by army officers came to power in Iran and Turkey. "[B]oth illiberal currents of the modern Middle East," writes de Bellaigne, "Islamism and militarism, received a major impetus from Western empire-builders." As often happens in countries undergoing social crisis, the aspirations of the Muslim world's translators and modernizers, such as Muhammad Abduh, largely had to yield to retrograde currents.

Ex Output:
Islamism and militarism

Ex Input:
What needs consistency?, Context: The simplest valve gears give events of fixed length during the engine cycle and often make the engine rotate in only one direction. Most however have a reversing mechanism which additionally can provide means for saving steam as speed and momentum are gained by gradually "shortening the cutoff" or rather, shortening the admission event; this in turn proportionately lengthens the expansion period. However, as one and the same valve usually controls both steam flows, a short cutoff at admission adversely affects the exhaust and compression periods which should ideally always be kept fairly constant; if the exhaust event is too brief, the totality of the exhaust steam cannot evacuate the cylinder, choking it and giving excessive compression ("kick back").[citation needed]

Ex Output:
exhaust and compression periods

When was the first Greek opera preformed?, Context: The modern Greek theatre was born after the Greek independence, in the early 19th century, and initially was influenced by the Heptanesean theatre and melodrama, such as the Italian opera. The Nobile Teatro di San Giacomo di Corfu was the first theatre and opera house of modern Greece and the place where the first Greek opera, Spyridon Xyndas' The Parliamentary Candidate (based on an exclusively Greek libretto) was performed. During the late 19th and early 20th century, the Athenian theatre scene was dominated by revues, musical comedies, operettas and nocturnes and notable playwrights included Spyridon Samaras, Dionysios Lavrangas, Theophrastos Sakellaridis and others.
