单选题 .  ①Benjamin Franklin is portrayed in American history as the quintessential self-made man. ②In "Self-reliance," Emerson asks, "Where is the master who could have instructed Franklin...?" ③In fact, Franklin took instruction widely, and his scientific work was highly collaborative. ④Friends in England sent equipment needed for his electrical experiments, others, in Philadelphia, helped him set up his workshop there. ⑤Philip Syng constructed a device for generating electrical charges, while Tomas Hopkinson demonstrated the potential of pointed conductors. ⑥Franklin, in addition to being the group's theoretician, wrote and published its results. ⑦His fame as an individual researcher is partly a consequence of the shorthand by which when one person writes about a group's discoveries, history sometimes grants singular credit for collective effort.
45.  Which of the following best describes the function of the highlighted sentence? ______

   A:这句话就是作者提出的,作者不可能反对自己的观点。
   B:无关选项。
   D:这句话重点解释为什么人们认为富兰克林是独立的,而非强调富兰克林对集体的依赖程度。
   E:无关选项。
