In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Ex Input:
Of the potential effects on Russia that resulted in large-scale population losses, which one would be considered out of the nation's control?, Context: The first half of the 20th century in Russia and the Soviet Union was marked by a succession of wars, famines and other disasters, each accompanied by large-scale population losses. Stephen J. Lee estimates that, by the end of World War II in 1945, the Russian population was about 90 million fewer than it could have been otherwise.

Ex Output:
disasters


Ex Input:
Which sector of public higher education offers a more narrow range of degrees?, Context: According to the Framework Law (3549/2007), Public higher education "Highest Educational Institutions" (Ανώτατα Εκπαιδευτικά Ιδρύματα, Anótata Ekpaideytiká Idrýmata, "ΑΕΙ") consists of two parallel sectors:the University sector (Universities, Polytechnics, Fine Arts Schools, the Open University) and the Technological sector (Technological Education Institutions (TEI) and the School of Pedagogic and Technological Education). There are also State Non-University Tertiary Institutes offering vocationally oriented courses of shorter duration (2 to 3 years) which operate under the authority of other Ministries. Students are admitted to these Institutes according to their performance at national level examinations taking place after completion of the third grade of Lykeio. Additionally, students over twenty-two years old may be admitted to the Hellenic Open University through a form of lottery. The Capodistrian University of Athens is the oldest university in the eastern Mediterranean.

Ex Output:
Technological sector (Technological Education Institutions (TEI) and the School of Pedagogic and Technological Education)


Ex Input:
What happens if an antenna has a greater reactance versus impedance?, Context: Instead, it is often desired to have an antenna whose impedance does not vary so greatly over a certain bandwidth. It turns out that the amount of reactance seen at the terminals of a resonant antenna when the frequency is shifted, say, by 5%, depends very much on the diameter of the conductor used. A long thin wire used as a half-wave dipole (or quarter wave monopole) will have a reactance significantly greater than the resistive impedance it has at resonance, leading to a poor match and generally unacceptable performance. Making the element using a tube of a diameter perhaps 1/50 of its length, however, results in a reactance at this altered frequency which is not so great, and a much less serious mismatch which will only modestly damage the antenna's net performance. Thus rather thick tubes are typically used for the solid elements of such antennas, including Yagi-Uda arrays.

Ex Output:
poor match
