Answer:
autobiography,
since she's writing it about herself
I think it could be six but if you mean their is 3 more dancers added then it would be 9 singers
Opaque means it's not see through, not clear, or transparent
Period goes inside the quotations and what is the question
First person
It takes a bit of reading into the passage to see what point of view it is, because there is little indication in the first paragraph. The first indication that it is written in first person is the use of "us" at the end of that first paragraph. Then, in the subsequent paragraphs the reader sees that the author uses "I" several times, indicating first person perspective.
