Alright so I never actually read the book so please take this with a grain of salt. From what I have just read it seems that Gogol comes to accept his non-American side and appreciate his Indian-American identity. I'm not sure why he comes to terms with it, but apparently he does. In the ending he sits down and reads the book his dad gives him by Nikolai Gogol. So yes, I think he does accept his name. However I strongly encourage you to verify that if you have the book. I hope this helped :)
Do you have options or no?
D, 19th century refers to 1800 and 20th to 1900 but it doesn’t include/contrast past music, so wrong. C doesn’t help you with past music. B could be of use, but the report is about 1920 big band music and not hip hop. And A would allow you to have the best information from a first person source along with their contracting ideas with today’s and the pasts music, so A is the right answer.
