Which title names a musician who is hired on an as-needed basis as part of an orchestra or band being recorded, but is not part of the featured group?
a. contractor
b. recording artist
c. session musician
d. core musician

I think the answer is b, but i'm not sure

The answer is a. dramatic movement

Iwould go with write exactly two extra paragraphs to point out additional information. but the keyword "exactly" throws me off. leads me to believe it's d. go with your gut feeling. either "write exactly two extra paragraphs" or "none of these".
