Explanation
Correct answer: B.
Choice B is the best answer. “Conversely” logically signals that the information in this sentence—that the actors’ responses were normal in nonacting contexts—presents the opposite of the previous finding that actors showed suppressed responses when their names were called during performances.
Why the other choices are wrong
Choice A
Choice A is incorrect because “specifically” illogically signals that the information about the actors’ normal responses in nonacting contexts provides specific details elaborating on the previous finding of suppressed responses during performances. Instead, the sentence presents the responses as opposites.
Choice C
Choice C is incorrect because “likewise” illogically signals that the actors’ normal responses in nonacting contexts are similar to the suppressed responses observed during performances. Instead, the sentence presents the responses as opposites.
Choice D
Choice D is incorrect because “thus” illogically signals that the actors’ normal responses in nonacting contexts are a result or consequence of the suppressed responses observed during performances. Instead, the sentence presents the responses as opposites.
