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

Example 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]
Example Output: exhaust and compression periods

Example Input: What was the view of superioroty of the Indian race seen as in the 18th century?, Context: Orientalist scholars of the 18th century like Sir William Jones marked a wave of enthusiasm for Indian culture and for Sanskrit. According to Thomas Trautmann, after this period of "Indomania", a certain hostility to Sanskrit and to Indian culture in general began to assert itself in early 19th century Britain, manifested by a neglect of Sanskrit in British academia. This was the beginning of a general push in favor of the idea that India should be culturally, religiously and linguistically assimilated to Britain as far as possible. Trautmann considers two separate and logically opposite sources for the growing hostility: one was "British Indophobia", which he calls essentially a developmentalist, progressivist, liberal, and non-racial-essentialist critique of Hindu civilisation as an aid for the improvement of India along European lines; the other was scientific racism, a theory of the English "common-sense view" that Indians constituted a "separate, inferior and unimprovable race".
Example Output: English "common-sense view

Example Input: How did a record company promote the 16 2/3 rpm records?, Context: Some recordings, such as books for the blind, were pressed at 16 2⁄3 rpm. Prestige Records released jazz records in this format in the late 1950s; for example, two of their Miles Davis albums were paired together in this format. Peter Goldmark, the man who developed the 33 1⁄3 rpm record, developed the Highway Hi-Fi 16 2⁄3 rpm record to be played in Chrysler automobiles, but poor performance of the system and weak implementation by Chrysler and Columbia led to the demise of the 16 2⁄3 rpm records. Subsequently, the 16 2⁄3 rpm speed was used for narrated publications for the blind and visually impaired, and were never widely commercially available, although it was common to see new turntable models with a 16 rpm speed setting produced as late as the 1970s.
Example Output:
two of their Miles Davis albums were paired together in this format
