Answer:
Allusion
Step-by-step explanation:
The term allusion refers to a figure of speech in which an object or circumstance from a different context is referenced to in an indirect way. Usually, this reference is only implied and it is up to the reader to make the connection. In this case, the author is making an allusion to the world of Broadway and to certain actresses. The author is also making an allusion to the character of Joan of Arc.
