We don't know that much about the Swing Mikado other than what we have in lines 45-51. The passage tells us that it drew on the m minstrel tradition in an ironic adaptation of a white classic- and in doing so it challenged audiences to think about race.
This is not much to go on- but we know two main things: It made audiences think critically, and it melded black traditions with a "white classic"
From this, we can determine that this play fits into the third approach mentioned between lines 30 and 35. Answer choice D would reflect a play that fits into the second (urban realism) approach.
