The problem: Answer a question about this article:
As the initial punk movement dwindled, vibrant new scenes began to coalesce out of a variety of bands pursuing experimental sounds and wider conceptual territory in their work. Many of these artists drew on backgrounds in art and viewed their music as invested in particular political or aesthetic agendas. British music publications such as the NME and Sounds developed an influential part in this nascent post-punk culture, with writers like Jon Savage, Paul Morley and Ian Penman developing a dense (and often playful) style of criticism that drew on critical theory, radical politics and an eclectic variety of other sources.
What was a common theme to post-punk music?
****
The answer: political or aesthetic agendas

The problem: Answer a question about this article:
The theoretical difficulties arise from the fact that all of the methods except the X-ray crystal density method rely on the theoretical basis of the Josephson effect and the quantum Hall effect. If these theories are slightly inaccurate – though there is no evidence at present to suggest they are – the methods would not give accurate values for the Planck constant. More importantly, the values of the Planck constant obtained in this way cannot be used as tests of the theories without falling into a circular argument. Fortunately, there are other statistical ways of testing the theories, and the theories have yet to be refuted.
What is the saving grace of relying on these theories?
****
The answer: there are other statistical ways of testing the theories, and the theories have yet to be refuted.
