26 The tiny transistors that control the flow of electricity in modern devices may one day be made of wood. Researchers in Switzerland have found a way to use heat and chemicals to widen the grooves in dry pieces of balsa wood. b l a n k these grooves become wide enough that electrical conductors can be passed through them. Which choice completes the text with the most logical transition?
Correct answer: D (parsed from the explanation — this source omits an answer key for this item)
Explanation
Choice D is the best answer. “As a result” logically signals that the information in this sentence—that the widened grooves in balsa wood can accommodate electrical conductors—is a direct consequence of the researchers’ method described in the previous sentence (using heat and chemicals to widen the grooves). Choice A is incorrect because “for example” illogically signals that this sentence provides an example of the researchers’ method described in the previous sentence. Instead, the sentence indicates a consequence of that method. Choice B is incorrect because “previously” illogically signals that this sentence describes an event that occurred before the researchers’ development of the method described in the previous sentence. Instead, the sentence indicates a consequence of that method. Choice C is incorrect because “in contrast” illogically signals that the information in this sentence contrasts with the previous sentence’s description of the researchers’ method. Instead, the sentence indicates a consequence of that method.
