Explanation
Correct answer: B.
Choice B is the best answer. Dramaturges help playwrights with storytelling and characterization. Choreographers often tell stories through dance, so they are also concerned with storytelling and characterization. This suggests that the fact that choreographers seek the help of dramaturges with the storytelling aspects of their dances should be “unsurprising.”
Why the other choices are wrong
Choice A
Choice A is incorrect. This inference isn’t supported. The beginning of the text does imply that this is true, but the end is leading to a conclusion about how choreographers use dramaturges.
Choice C
Choice C is incorrect. This inference isn’t supported. The text never mentions dances by choreographers who don’t incorporate narrative elements.
Choice D
Choice D is incorrect. This inference isn’t supported. The text mentions in passing that directors use dramaturges to conduct research, but it never suggests that directors and actors are too reliant on them. Also, the text is leading to a conclusion about how choreographers use dramaturges.
