The main point of the last paragraph can be seen in its final sentence, which states that "mathematical equations can sometimes tell such a convincing tale, they can seemingly radiate reality so strongly, that they become entrenched
in the vernacular of working physicists, even before there's data to confirm them." This point is borne out by the preceding lines of the paragraph, which recount the author's own experience of studying the still unproven Higgs field as it if were already a settled fact.
Choice B is incorrect because the anecdote the author shares about his own education does not demonstrate that physics, as a discipline, has come to operate differently over the course of his career. Choice C is incorrect because the details of the author's experience do not point to the process by which the existence of the Higgs field was confirmed, and indeed the passage does not describe that process at all. Choice D is incorrect because the passage broadly discusses the status of Higgs's theory at two different times (its initial rejection and later acceptance by physicists) and never considers how the details of the theory may have evolved.
