Why the other choices are wrong
Choice A
Choice A is incorrect. This choice doesn’t emphasize a potential problem with the wood-wide web theory. It uses a quotation to introduce the theory and its originator. It doesn’t mention any criticism or challenge to the theory.
Choice B
Choice B is incorrect. This choice uses a quotation, but it doesn’t emphasize a potential problem with the wood-wide web theory. It uses a quotation to describe the appeal and interest of the theory, but it doesn’t indicate why the authors are concerned or what evidence they have.
Choice D
Choice D is incorrect. This choice doesn’t use a quotation at all. It paraphrases the main idea of the 2022 study, but it doesn’t include any specific words or phrases from the notes. It also doesn’t emphasize a potential problem with the theory, but rather its popularity.
