Choice C is the best answer. The fourth paragraph describes Reznick's rationale for moving populations of guppies from one body of water to another. The last sentence of the paragraph states, "This kind of real-world manipulation of nature is called 'experimental evolution,'and it is growing increasingly popular among scientists working with organisms that reproduce quickly enough for humans to be able to see the outcome within our lifetimes." In other words, the fact that this type of research is "growing increasingly popular" means that it is becoming more widespread. Thus, the word "popular" as used in the passage most nearly means widespread.
Choices A, B, and D are incorrect because in the context of the passage, "popular" means widespread, not accessible (choice A), suitable (choice B), or likable (choice D).
