Input: Article: Its written transmission, along with the veneration bestowed on certain classical works, has led to the expectation that performers will play a work in a way that realizes in detail the original intentions of the composer. During the 19th century the details that composers put in their scores generally increased. Yet the opposite trend—admiration of performers for new "interpretations" of the composer's work—can be seen, and it is not unknown for a composer to praise a performer for achieving a better realization of the original intent than the composer was able to imagine. Thus, classical performers often achieve high reputations for their musicianship, even if they do not compose themselves. Generally however, it is the composers who are remembered more than the performers.

Now answer this question: How are performers expected to play a work due to written transmission?

Output: in a way that realizes in detail the original intentions of the composer

Input: Article: Although not specifically prepared to conduct independent strategic air operations against an opponent, the Luftwaffe was expected to do so over Britain. From July until September 1940 the Luftwaffe attacked RAF Fighter Command to gain air superiority as a prelude to invasion. This involved the bombing of English Channel convoys, ports, and RAF airfields and supporting industries. Destroying RAF Fighter Command would allow the Germans to gain control of the skies over the invasion area. It was supposed that Bomber Command, RAF Coastal Command and the Royal Navy could not operate under conditions of German air superiority.

Now answer this question: Why did the Luftwaffe bomb the RAF Fighter Command?

Output:
to gain air superiority
