Codex Berinensis,a Florentine copy of an ancient Roman medical treatise, is undated but contains clues to when it was produced. Its first 80 pages are by a single copiest, but the remaining 20 pages are by three different copiests,which indicates some significant disruption .Since a letter in handwriting identified as that of the fourth copiest mentions a plague that killed many people in Florence in 1148, Codex Berinensis was probably produced in that year.Which of the follwoing, if ture, most strongly supports the hyposthesis that Codex Berinensis was produced in 1148?A. Other than Codex Berinensis, there are no known samples of the handwriting of the first three copyists.B. According to the account by the fourth copiest, the plague went on for 10 months.C. A scribe woud be able to copy a page of text the size and style of Codex Berinensis in a day.D. There was only one outbreak of plague in Florence in the 1100s. E. The number of pages of Codex Berinensis produced by a single scribe becomes smaller with each successive change of copiest.答案是D ABCE我是能排除但是就是不懂为什么D是对的? 这题他说因为第四个copyist在一封信里提到了1148年有一场鼠疫导致很多人死了。作者怎么能够推断出这个copyist也一定死在那场鼠疫中呢导致CB就中断了?如果他真的是死在那场鼠疫中,那不是确定了就是1148年完成了么因为他自己信里也说了是1148年的鼠疫。为什么还要管这个世纪有没有发生其他鼠疫?
