Choice A is the best answer. Passage 1 discusses research conducted by biochemist Kim Lewis. As described in the second paragraph of  the passage, this research explored "a new way to tap the powers of soil microorganisms" in the laboratory and led to the development of teixobactin, a promising new drug that could "function effectively for decades," thereby addressing the problem of pathogens' resistance to antibiotics. The author of Passage 2 critiques the research described in Passage 1. In the first paragraph of Passage 2, the author declares that the methodology Lewis and others developed "is their most important finding . . . for it opens a gateway to cultivating a wealth of potentially antibiotic-producing bacteria." However, teixobactin "is less exciting" to the author of Passage 2 because it has proved ineffective at combating certain types of bacteria and large investments of time and money will be needed before it can be made available to the public at large, according to the second and third paragraphs of Passage 2. Therefore, the best description of the relationship between Passage 1 and Passage 2 is that Passage 2 offers an evaluation of the significance of the research discussed in Passage 1.
Choice B is incorrect because Passage 2 doesn't suggest a modification to the methodology described in Passage 1. Instead, the author of Passage 2 embraces the "simple and elegant" methodology described in Passage 1. Choice C is incorrect because Passage 2 doesn't use concrete examples to illustrate concepts considered in Passage 1. Instead, it evaluates the significance of the research. Choice D is incorrect because Passage 2 doesn't take a dismissive stance regarding the findings mentioned in Passage 1. The author of Passage 2 endorses the methodology described in Passage 1, and concedes that teixobactin "doesn't look bad," while outlining some reservations about the drug's value.
