答案精析：词组辨析题。本题重点考查句子与上文之间的逻辑关系。前一句中提到，基于预防原则，人们可以考虑听从食品标准局的建议。而空格所在句的大意是：____，吸烟会引发癌症这一传言在被证实____之前，就已经流传了许多年。由此可知，后一句话是对前一句话起到支撑论证的作用。用吸烟致癌的例子来进一步说明听从食品标准局的建议是可取的。After all表示“毕竟”，在这里可以起到加强语气、推出结论的作用，符合语境，故正确。

错项排除：吸烟致癌的传言很多年后才得以证实这件事，并不是经常发生的，也没有遵循任何定义或是存在必然性，故A、C两项错误。B项In particular表示一种递进关系，与原文中前后两句话的逻辑不符，故排除。
