This question is about the article "Lin-Manuel Miranda", by Jessica McBirney.
Answer:
a. The author shows how Miranda changed Hamilton from song to mixtape to musical.
Step-by-step explanation:
In the section "In the Heights" we can see how Miranda ascended to musicals, being a notable name in this industry. He took advantage of this moment to specialize and take his talents and skills to another level, the level that would allow him to succeed in writing songs for "Hamilton".
Mirando wanted to capture Hamilton's mentality, his anxieties and his intelligence. So he started writing a song for Hamilton, which soon led him to a mixtape that captured all the complexity of this character. The mixtape did so well that it was transformed into the musical "Hamilton", one of the biggest and most sought after musicals on Broadway.
