It refers to his composition which lasts for four minutes and 33 seconds. It is rather controversial because there is no music at all - John Cage performed this before his confused audience who didn't know what was going on.

I think the best answer would be : c. Classic rock emerged in the 1960s at the same time the society rebelled

Hope this helps
