Explanation
Correct answer: B.
Choice B is the best answer. "In so doing" logically signals that the information in this sentence about Gibson’s piece—that it blurs the distinction between contemporary art and traditional crafts—is a result or consequence of the piece’s blending of particular Native and non-Native cultural symbols.
Why the other choices are wrong
Choice A
Choice A is incorrect. "Conversely" illogically signals that the information in this sentence contrasts with the previous information about the blending of particular cultural symbols in Gibson’s piece. Instead, it presents a result or consequence of that information.
Choice C
Choice C is incorrect. "For instance" illogically signals that this sentence provides an example supporting the previous information about the blending of particular cultural symbols in Gibson’s piece. Instead, it presents a result or consequence of that information.
Choice D
Choice D is incorrect. "In particular" illogically signals that this sentence provides specific details elaborating on the previous information about the blending of particular cultural symbols in Gibson’s piece. Instead, it presents a result or consequence of that information.
