Scientists typically do their most creative work before the age of forty. It is commonly thought that this happens because aging by itself brings about a ------------------------------- loss of creative capacity. However, a study has found that almost all ------------------------- scientists who produce highly creative work beyond the age of forty entered their fields late and less than a dozen years before their creative breakthroughs. Since creative breakthroughs by scientists under forty also ------------------------------------------------------------ generally occur within a dozen years of the scientists’ entry into the --------------------------------------------------------------------------- field, the study’s finding strongly suggests that the real reason why ----- scientists over forty rarely produce highly creative work is not due to age but rather because most have spent too long in their fields. boldface題 C.The first is an explanation that the argument challenges; the second provides evidence in support of a competing explanation that the argument defends. E.The first is an explanation that the argument defends; the second is evidence that has been used to challenge that explanation. 答案是C 可是我覺得E好像也對 請問這兩個選項有啥不同和為啥選C 謝謝~ --
